PURPOSE OF THE STUDY Partial knee replacement appears to be an appropriate surgical solution of unicompartmental knee joint osteoarthritis in correctly indicated cases. The purpose of our study was to evaluate the mid-term outcomes of unicondylar knee replacement using the Oxford Phase III system in the group of patients treated by the First Department of Orthopaedic Surgery, St. Anne s University Hospital Brno. MATERIAL AND METHODS The prospective study evaluated 47 patients (in 4 patients bilaterally) after the Oxford unicompartmental knee replacement performed between 2011 and 2016. The patients were evaluated using the Knee Society Score (KSS), Oxford Knee Score (OKS) and radiological examination performed at 7.3 years after surgery on average. All the patients were operated on by the same surgeon. RESULTS Based on the questionnaires and the clinical examination, the clinical and functional status was assessed, using the Knee Society Score (KSS). The mean preoperative KSS and FS values were 59.8 and 56.5, respectively. The postoperative KSS and FS values were 91.2 and 83.4. The mean preoperative value of the Oxford Knee Score (OKS) was 27.3. Postoperatively the values reached 40.7 on average. Based on the radiological examination, the lower limb correction of axis in the frontal plane was assessed. The mean axis correction was 3.1°. The mean tibial component slope measured on lateral radiograph was 82.7°. The basic analysis of X-rays did not reveal any component malposition. The implant survival rate was calculated using the Kaplan-Meier cumulative survival curve. In our group of patients, the mean survival rate of Oxford Phase III unicondylar knee replacement at 7.3 years postoperatively is 98.0%. DISCUSSION Many studies have reported excellent results of unicondylar knee replacement and a long survival rate of over 90%. Still debated, however, are the indication criteria and also the importance of the surgeon s experience and mastery of the surgical technique. CONCLUSIONS The results of the study confirm our excellent clinical experience and the survival rate of 98% at the mean follow up of 7.3 years after surgery shows great promise for quality long-term results. Overall, crucial for the success of UKR continues to be the compliance with the indication criteria for surgery. The choice of the type of implant and, last but not least, the correct surgical technique and postoperative rehabilitation programme are also important. Key words: unicompartmental knee replacement, Oxford Phase III, osteoarthritis of the knee.

PURPOSE OF THE STUDY Our study aimed to assess the mid-term outcomes and complications with the ICON hip resurfacing system and to carry out a detailed analysis of pitfalls and risks associated with pairing the bearing surfaces of metal-on-metal hip implants. MATERIAL AND METHODS A total of 52 hip joints were assessed in 43 patients who received the ICON hip resurfacing system at our department between 2009 and 2013. The cohort included 34 men and 9 women. Their age at the time of primary surgery ranged from 34 to 67 years, with the mean age of 51.8 years. The mean follow-up was 7.6 years. The evaluation focused on the position and osseointegration of both components, bone remodelling around the implant, and signs of potential aseptic loosening. The functional status of the hip was assessed by Harris Hip Score. RESULTS The primary stability of both components was always good, there were no femoral neck fractures reported in our cohort. All the acetabular components were stable, showing appropriate osseointegration, with no radiolucent zones or signs of osteolysis around them. There was not a single case of the femoral component stem being in a biomechanically disadvantageous varus position. In zone I and III according to Beaulé, cancellous bone osteolysis developed in two patients. The narrowing of the femoral neck below the end of the femoral component, compared to postoperative X-rays, achieved the mean value of 1.3% according to Grammatopolouse. The HHS increased from 64 to 95.5 points. An excellent outcome was observed in 48 joints, whereas the outcome of the remaining 4 joints was very good. The mean survival rate of the resurfacing hip implant calculated using the Kaplan-Meier analysis achieved 100%. The cobalt and chromium levels in the blood of patients did not exceed the reference physiological value. DISCUSSION The resurfacing system enables to preserve the bone tissue of the metaphysis and a part of the femoral head. The reduced mechanical endurance of the peripheral part of femoral components smaller in size caused by implant malposition resulted in fatal consequences in the ASR system. Greater range of motion conditioned by the design of the resurfacing system led to a mechanical wear, with a significant increase in the concentration of metal particles in the effective joint space. The elevated levels of cobalt and chromium ions in some patients induced delayed-type hypersensitivity with subsequent development of aseptic lymphocyte-dominated vasculitis associated lesions presented as peri-acetabular changes (pseudotumors to osteolysis) with subsequent failure of implant fixation. We have not observed this complication in the ICON system as yet. In patients suffering from hip pain after the resurfacing hip arthroplasty and simultaneous high chromium and cobalt blood levels, pelvic CT/MRI is indicated with reduction of artefacts around the metal material. Surgical treatment of soft tissue affections, bone defects and reimplantation using conventional or revisioncementless components is a possible treatment option. CONCLUSIONS The ideal patient indicated for hip resurfacing is a physically active man under 60 years of age (with a femoral head size of 54-60 mm), with primary or secondary osteoarthritis, no joint deformity, with a good quality bone tissue in the femoral neck and head region. As for the functional performance, the resurfacing system allows the patients a large range of motion with very good joint stability immediately after surgery. Despite that, the metal-on-metal tribological pairing must be approached with caution. The risk of developing lesions associated with ALVAL is unpredictable. In our cohort of patients with ICON hip resurfacing system, mostly excellent outcomes with minimum complications were reported provided the indication criteria and the correct surgical procedure had been complied with. Key words: hip resurfacing system, metal articulating surfaces, adverse reaction to metal particles, aseptic lymphocytedominated vasculitis associated lesions, pseudotumor.

The case report presents the case of a five-year-old boy who fell off a scooter and sustained a blow to the left temporal region of his head. During a CT examination in the district hospital he suddenly showed a deterioration in the level of consciousness. Subsequent treatment along with transport to a specialized department were aimed at preventing secondary pathological changes and maintaining pressure-volume homeostasis of the brain. High-quality controlled ventilation with effective pharmacotherapy and gentle transport were essential. At the target specialized department, cerebral oedema in the left temporal region and aspiration in the right upper lung lobe were identified. The boy was extubated after 6 hours of controlled ventilation and discharged to an intermediate care bed two days later without any serious consequences. Key words: cerebral oedema, haemodynamic swelling, severe head injury.

PURPOSE OF THE STUDY The retrospective study of patients treated for sacral chordoma with respect of complications, clinical outcomes and longterm survival is presented. Three main hypotheses have been formulated. Hypothesis 1: survival of patients with respect to generalization of the disease, manifestation of local recurrence and metastases with a R0 resection margin achieved is longer than survival of patients with a R1 or R2 resection margin. Hypothesis 2: survival of patients with the tumor resected from low endplate of S2 distally is longer than in tumors with resection above this level. Hypothesis 3: resection of large tumors with tumor volume greater than 800 cm³ is associated with a significantly shorter survival than resection of tumors with tumor volume less than 800 cm³. MATERIAL AND METHODS A total of 12 patients (7 women, 5 men), with the mean age of 54.3 years, underwent surgical treatment at our department in 1998-2018. Sacral chordoma proximally achieved S1 level in three cases, S2 level in four cases and S3 level in five cases with volume less than 800 cm³ in eight and greater in four patients. In nine patients sacrectomy using isolated posterior approach was performed and in three patients antero-posterior approach was applied. The Kaplan-Meier survival curve was calculated to estimate the survival of patients. The patients were divided into groups and subsequently compared with respect of achieved radicality of surgical resection, i.e. R0 vs. R1 or R2 resection, secondly of the proximal margin of the tumor/resection, i.e. S1 or S2 vs. S3 distally, and thirdly of the volume of the tumor, i.e. less than 800 cm³ vs. more than 800 cm³. RESULTS At the time of evaluation, a total of seven patients were alive (58.3%), with the mean survival of 9.5 years. One patient died from complications associated with the treatment of obstructive ileus manifested 10 months after primary surgery. The remaining four patients died in relation to the generalization of the disease 14.8 years after primary surgery on average. All the patients, in whom R0 resection was achieved, at the average time of evaluation of 7.3 years (range 2.8-15.8 years) showed no signs of local recurrence or generalization of the disease, whereas in group with R1, R2 resection at the time of evaluation only two patients were still alive, both 16.8 years on average (range 15.2-18.4 years) after surgery with repeatedly treated recurrencies. Frequent postoperative complications were observed in a total of five patients (41.7%). DISCUSSION The study did not confirm any difference in patient's survival with respect of the proximal margin affection of sacrum or tumor size. The decisive factor for survival of patients with sacral chordoma is achieving the R0 resection. The size of the chordoma and proximal achievement increase the complexity of surgery, manifestation of early perioperative and subsequently postoperative complications. CONCLUSIONS In primary surgical treatment of sacral chordoma, we always try to achieve R0 resection. In the case of low-volume tumors from S3 distally, we resect the tumor using the isolated posterior approach. The anterior-posterior approach is preferred in the case of large tumors presenting in the S1/2 region. Key words: sacral chordoma, sacral cancer, wide resection, sacrectomy, vertical rectus abdominus myocutaneous (VRAM) flap.

PURPOSE OF THE STUDY We aimed to evaluate the biomechanical properties of quadriceps tendon graft with a bone plug ending (QTBP) and a quadriceps graft with a tendinous ending(QTT) fixed on the femoral side with different fixation devices. MATERIAL AND METHODS Twenty-five paired 2-year-old calf QTs and 25 paired 2-year-old sheep femurs were used for this study. 90x8 mm central part of the quadriceps tendons with or without a bone plug was harvested. 8×25 mm tunnel was placed in lateral condyles. The QTT was fixed with four different fixation devices, including the adjustable suspensory system (QTT-ASS, group 1), biodegradable interference screws (QTT-BIS, group 2), titanium interference screws (QTT-TIS, group 3), and an adjustable suspensory system + biodegradable interference screws (QTT-(ASS+BIS), group 4); QTBP was fixed with titanium interference screws (QTBP-TIS, group 5). All groups were tested in a servohydraulic materials testing machine. Stiffness(N/mm), slippage of the tendon(mm), and the ultimate tensile load-bearing ability(N) of the groups were tested. The Kruskal-Wallis H test was used with the Monte Carlo simulation technique to compare the nonparametric variables of stiffness, slippage, and ultimate tensile load. Dunn's test was used for the post hoc analyses. RESULTS Group 3 had the stiffest fixation (median 45.09 N/mm). The amount of slippage was highest in group 1(median 6.41mm). Group 1 was the most resistant group against a tensile load during the load-to-failure test(464 N). Fixing the QTT with the ASS and BIS in group 4 increased both stiffness and ultimate tensile load strength. There was no significant difference between the QTBP and QTT fixed with titanium screws. Fixing QTT with titanium screws was significantly superior to fixation with BIS(p < 0.05). CONCLUSIONS This study demonstrates that QTBP fixation with TIS have no advantage over QTT fixation with TIS on the femoral side. Although the QTT group fixed with ASS was the most resistant group against tensile forces during load-to-failure test, amount of slippage was highest for this group as well. Thus, if an ASS is to be used, a strong tension force must be applied prior to tibial side fixation to prevent further slippage of the graft in the tunnel. Key words: anterior cruciate ligament, quadriceps tendon graft, femoral side, fixation, biomechanical properties.

PURPOSE OF THE STUDY To compare topical and intravenous (IV) administration of tranexamic acid (TXA) 2 g in patients undergoing total hip arthroplasty (THA), or total knee arthroplasty (TKA). MATERIAL AND METHODS In total, 452 patients undergoing THA or TKA were randomised to 3 groups: 1) the IV TXA group received 2 doses of TXA 1 g intravenously 3 hours apart; 2) the topical TXA group received TXA 2 g topically, and 3) the NO TXA - control group. Furthermore, each group was divided in two subgroups by performed surgery (THA versus TKA). The following endpoints were used for final analysis: postoperative blood loss, transfusion requirement, haemoglobin drop and postoperative complications (haematoma, surgical site infection, thromboembolism, early surgical revision). RESULTS Both topical and IV administration of TXA significantly reduced postoperative bleeding (mean ± standard deviation) after THA and TKA (topical 504.4±281.0 ml, IV 497.3±251.7 ml, NO 863.1±326.4 ml, p<0.001). Topical use was superior to IV in reducing postoperative drainage output in THA (topical 377±213.3 ml, IV 518.1±259.0 ml, p<0.01). On the opposite, IV use was superior to topical in drainage output in TKA (topical 646.1±281.3 ml, IV 457.8±235.8 ml, p<0.01). The differences in transfusion requirement and Hb drop between these administration methods were not statistically significant (p≥0.05), but any TXA administration was significantly better than no TXA in all endpoints of efficacy (p<0.001). The lowest complication rate was observed in the topical group (NO 24%, IV 19%, topical 7.5%). DISCUSSION Consensus on optimal TXA dosing regime in primary hip and knee arthroplasties is still missing. Use of TXA therapy in routine clinical practice is highly individualized in accordance with the current approach of personalized medicine. Topical application seems to be the safest route of TXA administration. However, precise application technique is essential. IV TXA is beneficial especially in patients with some bleeding coagulopathies undergoing TKA with a tourniquet. Repeat doses of TXA are not usually necessary after completed primary arthroplasties. CONCLUSIONS IV and topical TXA 2 g have similar effect on reduction of transfusion requirements and haemoglobin drop in THA and TKA. The IV route is superior to topical in TKA while topical TXA reduces complications in both THA and TKA. Key words: tranexamic acid, total hip arthroplasty, total knee arthroplasty, topical administration, intravenous administration.

PURPOSE OF THE STUDY It was a prospective, randomised, unblinded study. Effects of the application of platelet-rich fibrin (PRF) on the anatomic anterior ligament reconstruction were examined. MATERIAL AND METHODS A total of 40 patients who underwent a surgery between 2012 and 2014 were enrolled in the study. The patients were randomised into two groups: the group with PRF application (n=20) and the group without PRF application (n=20, control group). The study included 11 women and 29 men, with the mean age at the time of inclusion into the study 29.1 years. Vivostat ® PRF was obtained perioperatively from the patient s blood and applied intraoperatively to the hamstring tendon graft. The ACL graft healing was assessed through magnetic resonance (MRI) at 6 and 12 months postoperatively. The clinical outcomes (the Lysholm score and the IKDC Subjective score, return to pre-injury sport levels, Pivot-shift test, graft failure) as well as standardised laxity measurements using GenouRob arthrometer were performed preoperatively and 12 months after surgery. RESULTS The study was completed by thirty-three (33) patients (17 in the PRF group and 16 in the control group). In two cases, postoperative graft failure was reported (both cases in the control group). No significant differences were found in the process of graft ligamentization evaluated through MRI (p=0.07). No significant difference between the groups was identified with respect to return to pre-injury sport levels (p=0.232), or the Lysholm score and IKDC Subjective score (p=0.259, and p=0.364 respectively). The postoperative knee laxity measurement using Genourob arthrometer did not reveal any significant differences between the PRF group and the control group. DISCUSSION Results similar to those arrived at by our study have recently been published also by other authors worldwide. We can therefore assume that the application of PRF can be of benefit, especially at the early stage of healing. The results still need to be verified on a larger study group, the study design should focus on the development in the early postoperative period. CONCLUSIONS In our study group, no significant difference was observed in the evaluated subjective and objective clinical parameters. Only the parameter regarding the ACL graft failure fell just short of statistical significance, namely to the disadvantage of the group without the PRF application. Key words: anterior cruciate ligament, arthroscopy, anatomic ACL reconstruction, magnetic resonance imaging of the graft, platelet-rich fibrin, graft healing, MRI signal intensity of the graft.

PURPOSE OF THE STUDY The literature is conflicting as to whether the high hip center (HHC) reconstruction in total hip arthroplasty (THA) is an ideal option for patients with severe developmental dysplasia of the hip (DDH). This study aimed to compare the mid-term functional and radiographic outcomes of THA using HHC versus anatomical hip center (AHC) technique in Crowe types II and III DDH. Our hypothesis was that there may be no differences in terms of functional and radiographic outcomes between patients who underwent THA using HHC or AHC. MATERIAL AND METHODS Fifty-seven patients who underwent a primary THA due to Crowe type-II or type-III DDH were retrospectively reviewed and included. Patients were divided into two groups as per the hip center reconstruction: Group A (AHC technique) and group H (HHC technique). A cementless cup was inserted in 25 hips (19 female, 6 male; mean age = 51 years, age range = 28-67)) at near-AHC in group A and 32 hips (22 female, 10 male; mean age = 53 years, age range = 29-68) at HHC position in group H. To assess clinical status, the Harris Hip Score (HHS) was used at the final follow-up. In radiographical assessment, component loosening and osseointegration of the acetabular cup were examined on follow-up radiographs. Complications were also recorded. RESULTS The mean follow-up was 41 months (range, 25-84) in group A and 40 months (range, 24-86) in group H. The mean HHS was 83 (range, 74-91) in group A and 83.6 (range, 73-94) in group H (p = 0.741). Osteolysis was determined in three patients from each group. The other 51 cups demonstrated a minimum of one radiographic sign of osseointegration. Although the overall complication rate was higher in group A (64%) than in group H (46%), this difference reached no statistical significance (p = 0.11). CONCLUSIONS The HHC technique using cementless acetabular fixation seems to be a valuable alternative option to AHC technique in cases of Crowe types II and III DDH. Key words: High hip center; anatomical hip center; center of rotation; total hip arthroplasty; dysplastic hip; developmental dysplasia of the hip; Crowe type II; Crowe Type III.

PURPOSE OF THE STUDY The paper focuses on the potential use of nail osteosynthesis in diaphyseal metastases of long bones. The purpose of the paper is to assess the outcomes of intramedullary osteosynthesis in pathologic and impending pathologic fractures, to evaluate patient survival and potential complications. MATERIAL AND METHODS The retrospective study evaluated a cohort of 42 patients (19 men and 23 women) in whom intramedullary osteosynthesis was performed for complete pathologic fracture (28 patients) or impending pathologic fracture (14 patients) between 2010 and 2019. Of the total number of 42 patients, 31 patients' lower limbs were affected, namely by 17 pathologic fractures and 14 impending fractures. There were 11 humerus fractures. The mean age was 61.8 years (range 41-84 years). In the followed-up cohort, the patient survival after osteosynthesis with intramedullary nails, complications occurred and post-operative mobility of the patient were assessed. The functional outcomes were evaluated using the Musculoskeletal Tumor Society (MSTS) scoring system. The unpaired Mann-Whitney test was used to test the significance of the difference in functional outcomes and survival between the followed-up groups. Survival longer than 6 months was evaluated using Fisher's exact test. The level of statistical significance used for the test was p 0.05. RESULTS The investigated indicator was patient survival, which was 11.3 months (range 1-50 months) on average. In the group of impending fractures, the mean survival was 13.5 months. In the group of pathologic fractures, the survival was 10 months. The functional outcome in 16 followed-up patients at three months after intramedullary osteosynthesis according to the MSTS score was 46.9% (30-66.7%). At the level of significance of p 0.05, the statistically significant difference in the functional outcomes between the group with preventive intramedullary osteosynthesis and the group with nail osteosynthesis of the pathologic fracture was not confirmed (p=0.952). When comparing the patient survival after nail osteosynthesis with impending pathologic fracture and the survival of patients with pathologic fracture, a statistically significant difference in survival between these two groups (p=0.520) was not confirmed. The patient survival of longer than 6 months was 71% in the group of impending fractures and 40% in the group of pathologic fractures. DISCUSSION The occurrence of pathologic fracture is associated with increased pain, loss of function, and according to some authors, a higher risk of death. Surgical treatment options include intramedullary osteosynthesis, plate osteosynthesis with cement filling, implantation of an intercalary spacer, and implantation of tumor endoprostheses. When deciding on a surgical procedure, an account is taken of the expected survival of the patient. In patients with an expected survival of up to 6 months, intramedullary osteosynthesis is indicated as a palliative surgical intervention. The most common complications include implant failure and metastatic progression. CONCLUSIONS Intramedullary osteosynthesis is the method of choice in treating pathologic fractures or impending pathologic diaphyseal fractures of long bones in patients with an expected predicted survival of up to 6 months. Intramedullary osteosynthesis aims to reduce pain and enable early verticalization. The study confirmed the importance of preventive intramedullary osteosynthesis and its effect on survival compared to the survival of patients with a pathologic fracture. Key words: skeletal metastases, diaphyseal metastases, intramedullary osteosynthesis, pathologic fracture, impending fracture.

PURPOSE OF THE STUDY This paper aims to detect, through a retrospective study, the migration of the tips of used metal implants (K-wires or a screw) in the direction out from the proximal femoral epiphysis as a part of studied basic radiometric characteristics of the cohort, with no intention of the authors to evaluate the therapy outcomes. MATERIAL AND METHODS It was a retrospective multicentre study including patients of two orthopaedic clinics and one department of orthopaedics treated in the period 2005-2018. The same treatment procedure was used in all three centres. The "in situ" fixation was indicated in patients, in whom the Southwick angle in anteroposterior and Lauenstein views was not much greater than 30°, whether primarily due to a mild slip or thanks to careful reduction either in acute or acute-on-chronic forms. All X-rays were measured by a single author (M.S.). In AP and Lauenstein view, overlap of the implant tip (K-wire or a screw) above the subcapital growth plate, the height of epiphysis and Southwick angle are measured at the beginning and at the end of treatment. In a smaller group of patients, also the inter-observer error (M.S. and J.P.) was identified. RESULTS K-wire transfixation was used in 43 patients (50 joints), with the mean age of 11.7 years and the mean duration of transfixation of 18.2 months. The slip of the implant tip out of the head, assessed separately for each introduced K-wire and then averaged, was in both views considered statistically significant (in AP view the level of significance was 5% (p-value = 1.393 x 10^(-6) < 0.05) , in Lauenstein view the level of significance was also 5% (p-value = 0.0001652 < 0.05)). The Wilcoxon signed rank test with continuity correction was used. Transfixation by screw alternatively with one K-wire was used in 23 patients (28 joints), with the mean age of 12.4 years and the mean duration of transfixation of 14.4 months. The slip of the screw tip outside the head was assessed as significant (in AP view at the level of significance of 5% (p-value = 9.41 x 10^(-5) < 0.05), in Lauenstein view at the level of significance of 5% (p-value = 0.003557 < 0.05)). The Wilcoxon signed rank test with continuity correction was used. DISCUSSION This paper aims to detect, through a retrospective study, the so-called migration of the tips of used metal implants (K-wires or a screw) outside the femoral head. Smooth and thin implants such as Kirschner wires should not compromise the continuing growth from subcapital growth plate contrary to the AO screw with threads in the femoral head, the screw head rested against the lateral cortical bone and the screw inserted as a compression one. Nonetheless, with some exceptions, the literature confirms the continued growth of the femoral neck even in the case of screws. In general, implants that do not compromise femoral neck growth provide an opportunity to remodel the anterolateral prominence of the femoral metaphysis, especially in younger patients. In agreement with other authors, the data from our study confirmed, even after a short period of time, a certain degree of proximal femoral remodelling expressed by changes in the Southwick angle. CONCLUSIONS Our study confirmed that in the case of "smooth" K-wires as well as cannulated screws the tips of both implants migrate outside the head. The differences were statistically significant. Therefore, the introduction of a conventional cannulated screw cannot be claimed to immediately produce the effect of epiphyseodesis. Yet, smooth implants less compromise the growth of the femoral neck, which is why they have recently been preferred. Key words: coxa vara adolescentium, metal implants, migration.

PURPOSE OF THE STUDY The purpose of this study was to conduct an epidemiological study of hand fractures in adult population. MATERIAL AND METHODS A retrospective observational study in a population of 470,000 habitants was performed. Over the course of three years, all patients over 16 years of age who were diagnosed with fracture or fracture-dislocation at the level of a carpal bone, metacarpal and/or phalange were included. These fractures were classified according to the International Classification of Diseases 10th edition (ICD-10). Incidence rates, along with gender and age distribution were also studied. RESULTS 1,267 patients with a total of 1,341 hand fractures were included. They represented 29.7% of all upper limb fractures and 7.6% of all traumatological emergencies involving a bone fracture during that period. The most frequent ICD-10 group was S62.3, with the fifth metacarpal as the most often affected bone (39.7%). The most frequent location at the level of the phalanges (S62.5) was the proximal third of the proximal phalanx of the fifth radius. The global incidence rate was 99 fractures per 100,000 persons/year. No seasonal variation was observed. Only 10.2% of hand fractures received surgical treatment. DISCUSSION Several epidemiological studies have been published on fractures in the hand, but none have used the ICD-10 classification. Although the distribution of our stratified sample by age and gender was similar to those previously published, the incidence rate in our study was much lower. We may possibly extrapolate our results to the rest of the Spanish population and even to the rest of the population of southern Europe, given the scarcity of epidemiological studies on this matter in these geographical areas. CONCLUSIONS The ICD-10 classification is useful for the description and classification of hand fractures. The most often affected group is that including metacarpals of the long fingers (S62.3), being the distal level of the fifth metacarpal in young male patients the most frequent one. Most fractures are treated conservatively and in case of surgical treatment, the preferred surgical techniques include K-wire fixation, interfragmentary compression screws and plate osteosynthesis. Key words: epidemiology, incidence, fracture, fracture dislocation, carpal bones, metacarpals, finger phalanges.

PURPOSE OF THE STUDY Unplanned revision spinal surgeries constitute a complication in the treatment algorithm for the patient, surgeon and the entire treatment team. Any complication leading to an unplanned revision surgery is therefore undesirable. The percentage of complications referred to in publications on this topic focusing on unplanned revision surgeries only varies from 0.7% to 29.8%, with obvious diversity of causes and significant risk factors. The purpose of the submitted paper is to carry out a prospective evaluation of the most serious complications requiring unplanned revision spinal surgeries in the course of 13 years at a single department performing a broad range of spinal surgeries, namely 1300 procedures annually on average. MATERIAL AND METHODS In the period 2006 - 2018, a total of 16872 patients underwent a surgery at our department. During this period, in 556 patients an unplanned revision spinal surgery was performed. In agreement with literature, the patients were categorised by cause for revision: 1/ impaired wound suprafascial (superficial) healing - superficial infection, 2/ impaired wound subfascial (deep) healing - deep infection, 3/ surgical wound hematoma, 4/ deterioration or occurrence of new neurological symptoms, 5/ cerebrospinal fluid leak (liquorrhoea) and 6/ others. The patients operated on for inflammatory diseases of the spine with subsequent infectious complications, primarily treated at another department, and the patients with open spinal injury were excluded from the study. According to these criteria, a cohort of 521 patients was followed up, namely 236 (45.3%) women and 285 (54.7%) men, aged 1 year to 86 years, with the mean age of 55.0 years (median 60 years). Demographic effects, tobacco smoking and comorbidities were followed up in the cohort, together with the effects of surgery, diagnosis, surgical approach and physician. All parameters were statistically evaluated at a p-value below 0.05, including comparison with the control group. RESULTS Of the total number of 16872 operated patients, a group of 521 (3.09%) patients undergoing a revision surgery for complications was analysed in detail. Impaired wound healing - infection (SSI) was found in 199 (1.18%) patients, of whom superficial infection in 124 cases (0.73%) and deep infection in 75 cases (0.44%). Hematoma in a surgical site was detected in 149 (0.88%) patients. In 63 (0.37%) cases, deterioration of the existing neurological finding or occurrence of a new neurological finding were observed, in 68 (0.40%) cases cerebrospinal fluid leak was reported and in 40 (0.24%) cases other complications were identified. As concerns the surgical assistant, the percentage of complications in a board-certified physician is 2.77 (1.14 - 3.29%), in a medical resident it increases to 3.60 (0.00 - 9.38%) (p<0.05). The prevalence of smokers in the group with complications (N=521) was 34.7%. The control group (N=3650) included 30.1% of smokers (p<0.05). The mean age of patients in the group with complications (N=521) was higher, i.e. 55.0 years, with the median age of 60.0 years, than in the primary cohort (N=16872) with the mean age of 49.8 years and the median age of 52.0 years (p<0.05). The mean BMI in the group with complications was (N=521) 27.3, the median BMI was 26.9. In the control group (N=16872), the mean BMI was 27.11, the median BMI was 26.8. In this case the significance (p>0.05) was not confirmed. The complications prevailed strongly in posterior surgical approach, namely in 483 patients (92.7%). As concerns the surgically treated segment, lumber spine dominates with 320 (61.4%) cases. Corticosteroid therapy was used twice as often in women, namely in 13.1% vs. 6.3%. The group of patients with complications (N=521) showed a much higher average length of hospital stay of 12.8 days compared to the average of 4.6 days (N=16872). DISCUSSION In our cohort, the complication rate was 3.09%, of which infections constituted 1.18%, which is in agreement with similarly focused papers. As regards the patient-related factors, in our study the results reported by literature were confirmed with respect to the age, smoking and comorbidities. Moreover, the posterior surgical procedure, lumber spine surgery and presence of a medical resident are essential (p<0.05). No major age difference was observed between women and men (p>0.05). Obesity is one of the key risk factors, especially in infectious complications. In our cohort, a higher BMI did not increase the risk of complications in general (p>0.05). CONCLUSIONS In correlation with current literature, our cohort confirmed a significantly higher risk of complications leading to revision spinal surgery associated with age, smoking, posterior surgical procedure in thoracic or lumber spine, and presence of a medical resident as a surgical assistant. The average length of hospital stay was demonstrably longer in complicated patients, it almost tripled compared to the whole cohort. Contrary to literature, the effect of obesity on the occurrence of complications was not confirmed. Key words: spinal surgery, complications, infection, reoperation, risk factor, hematoma, cerebrospinal fluid leak, screw malposition, smoking, obesity.

With this case report, we introduced a rare and commonly overlooked cause of lateral snapping knee, a snapping popliteus in a 14-year-old female patient. She was initially treated for a lateral discoid meniscus, a common diagnosis in this age group. Because of the non-resolving symptoms, a second-look arthroscopy was performed and showed a popliteus tendon snapping over a tubercle on the lateral femoral condyle. Resection of the tubercle resulted with a successful outcome. In evaluating the snapping knee in young children, popliteus tendon should be kept in mind. Key words: snapping popliteus, tubercle, knee, arthroscopy, popping.

Osteoid osteoma is a primary benign bone tumor with rare intra-articular occurrence. Our case report describes a rare case of a 21-year-old man with long-term severe pain in the right hip region caused by osteoid osteoma managed by arthroscopic excision. The clinical finding of pains and a limited range of motion did not correlate with the normal plain X-ray finding. The osteoid osteoma was suspected based on the CT scan. In literature, several methods of resection of intraarticular osteoid osteoma of the hip are described. Since our department has long specialised in arthroscopic hip surgery and based on the available examinations the tumor appeared to be located within the arthroscopic reach, we decided for arthroscopic resection of the tumor. Our study comprises a detailed description of the entire surgical procedure, the used arthroscopic approaches and the arthroscopic technique of tumor excision. The histological examination of samples taken from the mass confirmed the suspected osteoid osteoma. The success of arthroscopic excision of the tumor was later confirmed also by very positive postoperative recovery when the patient very soon experienced a considerable reduction of pain observed during our five-year follow-up of the patient (Day 13, Week 2 and 6, Year 1, 2 and 5). During the follow-up period, an increase of the Harris Hip Score (13.5 preoperatively vs 76.6/91/94/96/96 postoperatively) and a decrease in VAS (9 preoperatively vs. 3/1/1/1/1) were reported. The follow-up CT and MRI performed at 2 or 5 years after surgery did not show tumor recurrence. The case report includes also illustrations consisting of X-rays, CT and MRI scans before and after surgery as well as multiple scans taken intraoperatively. It has to be emphasized that this is a rare case and an evaluation of a larger group of patients would be necessary to verify the successful outcomes of arthroscopic technique in treatment of the hip joint osteoid osteoma.

Given the low incidence of musculoskeletal tumors during pregnancy, publications on the subject are scarce and treatment guidelines nonexistent. We present five cases of musculoskeletal tumors in pregnant women, three with metastasizing malignant neoplasms and two with aggressive giant cell tumors. The three patients diagnosed during their gestational period were operated before the end of pregnancy, adapting surgical techniques to minimize risk to mother and fetus. Adjuvant therapies were postponed until the end of gestation. All newborns were delivered at term vaginally, except for one where a cesarean section was required. After a mean follow-up of 69.96 months (±56.38), all patients were free of disease, except for the one diagnosed with an extraskeletal myxoid chondrosarcoma who died at 4 years from diagnosis. Surgery plays a key role in the treatment of musculoskeletal tumors diagnosed during pregnancy. These patients must be treated by multidisciplinary teams at sarcoma reference hospitals, involving the obstetrics team in the decision-making process, and adapting each step of the diagnosis and treatment to the gestational period. Key words: pregnancy, musculoskeletal tumors, sarcoma, cancer, oncological surgery.

PURPOSE OF THE STUDY Radial head fractures in paediatric patients account for 5-19% of all elbow injuries and approximately 1% of all fractures in children. Non-displaced fractures are treated with plaster cast fixation. If the fracture is displaced, we proceed to closed reduction, or to osteosynthesis in case of unstable fragments. If closed reduction fails, we opt for open reduction and osteosynthesis. The prospective randomised clinical study aims to compare the two methods of minimally invasive osteosynthesis using the pre-bent Kirschner wire or Prévot nail and to identify differences between them. MATERIAL AND METHODS The prospective randomised clinical study was conducted in 2015-2019. The final cohort included 32 patients who met the inclusion criteria. The patients in whom other osteosynthesis implants had been used or in whom open reduction had to be performed were excluded from the study. Also excluded were the patients with serious concomitant injuries of elbow. For patients included in the cohort, demographic data, precise evaluation of the displacement and location of the fracture as well as the duration of plaster cast fixation and osteosynthesis implants used were recorded. In the clinical part, the methods were compared based on the achievement of full range of motion in dependence on the degree of original displacement, use of osteosynthesis implant, and occurrence of early and delayed complications. Clinical and radiological outcomes were compared. In both types of minimally invasive osteosynthesis, Métaizeau surgical technique was used. RESULTS Based on the clinical trial criteria, 26 (81%) excellent, 4 (13%) good and 2 (6%) acceptable outcomes were achieved. In 3 cases the loss of rotation was up to 20°, in 1 case the loss of flexion was up to 10°. In one patient the loss of flexion was 15° and rotation up to 30°. In another patient the loss of rotation was up to 40°. The radiological assessment showed 14 (44%) excellent outcomes, 15 good (47%) and 3 (9%) acceptable outcomes. The statistical analysis of both the groups of the cohort using non-parametric tests revealed no statistically significant differences in individual demographic parameters. The comparisons of both types of osteosynthesis in dependence on the degree of displacement by non-parametric Fisher's exact test showed no statistically significant difference in the radiologic or clinical results. The only statistically significant difference was observed in the duration of metal implant placement. DISCUSSION Comparable studies report excellent or good clinical outcomes in 80-95% of cases (1,13,16). In our cohort, excellent or good clinical outcomes were achieved in 30 patients (94%). In two patients, in whom Prévot nail was used, the outcomes were acceptable. Nonetheless, this fact did not result in any statistical significance when comparing the two methods separately or in comparisons based on the degree of displacement. CONCLUSIONS The comparison of the two methods of minimally invasive osteosynthesis revealed no statistically significant difference, namely not even when both the methods were compared based on the degree of displacement. When Kirschner wire is used, the possibility to remove the metal implant in the outpatient setting is considered to be an advantage. The drawback consists in potential penetration of the sharp Kirschner wire in the radiocapitellar joint, which we did not encounter when the second technique of osteosynthesis was used. The advantage of Prévot nail includes a lower risk of pin-tract infection. Key words: minimally invasive osteosynthesis, radial head, fracture, child.

PURPOSE OF THE STUDY Most humeral nonunions can be successfully treated with a single procedure, but some are more difficult to heal. Humeral nonunions which have two or more surgical procedures were defined as refractory humeral nonunions, and this condition is a very challenging condition. The aim of the study is to show the results of atrophic refractory humeral nonunion treated with open reduction and internal fixation and autogenous block iliac crest graft and spongioplasty. MATERIAL AND METHODS Refractory humeral nonunions treated with open reduction and internal fixation and autogenous block iliac crest graft and spongioplasty from January 2010 to March 2019 were included this study retrospectively. Patient baseline information, number of previous surgeries, comorbidities, follow-up time, fracture union time, and complications were recorded. The functional outcome was evaluated with the Constant scores and Mayo scores at the end of the first year. The primary outcome variable was mentioned as bony union. RESULTS A total of 13 refractory humeral nonunions included this study. The average age of the patients was 50.92±15.55 years (range, 26-78 years), and 8 of them were female. Preoperative and postoperative mean Mayo scores were; 56.54±17.84, and 85.38±7.49 respectively (p<0.001). Preoperative and postoperative mean Constant scores were; 45±11.71, and 80.62±5.38 respectively (p<0.001). DISCUSSION The strict application of basic nonunion principles can result in successful salvage of refractory humeral nonunions. But this concept may not provide sufficient solution for each situation. On the other hand, we also applied the basic nonunion principles. Compression plating and autogenous bone grafting and spongioplasty have been considered as the gold standard in the management of humeral shaft nonunion. CONCLUSIONS Open reduction and internal fixation and autogenous block iliac crest graft and spongioplasty should be considered as an alternative for the treatment of refractory atrophic humeral nonunions, whose treatment is a very challenging condition for surgeons. Key words: block graft, bone grafting, nonunion, refractory humeral nonunion, spongioplasty.

PURPOSE OF THE STUDY Population aging is connected with an increased incidence of chronic diseases. A common related problem is chronic skin ulcers, which, while not life-threatening, can significantly decrease the quality of the patient's life. The present study aims to evaluate new materials and methods to improve and accelerate the treatment of leg ulcers. MATERIAL AND METHODS Twenty-five patients with chronic ulcers treated using autologous growth factors applied on a nanofiber carrier were included in the cohort. The control group consisted of 15 patients treated using standard moist wound therapy. The surface area of the ulcer was measured on the 0th, 14th, 28th, 56th, 84th, 112th, 140th, 140th, and 168th day of treatment. Ulcer depth was measured on the 0th, 5th, 28th, 84th, and 168th day of treatment. Results were statistically processed and evaluated. RESULTS During the study, the defect area decreased in both the control and experimental group. Statistically significantly better results were observed in the experimental group relative to the progress of ulcer depth. The experimental group also had more healed ulcers. DISCUSSION Moistness is necessary for chronic wounds to heal; it is needed to ensure optimal cell growth, angiogenesis, and fibrinolysis. Wounds can be treated using non-active dressings with high absorption qualities; however, these do not guarantee optimal conditions for healing, or wounds can be treated with an interactive dressing that interacts with the wound surface. The third option for treatment is the use of bioactive materials that adhere to the wound and participate directly in the individual stages of healing. CONCLUSIONS The study found that autologous growth factors had statistically significant effects on the treatment of chronic ulcers. The authors believe that this method can accelerate the healing of primary post-injury or secondary postoperative wounds of lower leg soft tissues. Key words: trophic ulcer, autologous growth factors, microangiopathy, polyneuropathy, diabetes mellitus.

PURPOSE OF THE STUDY The hip fracture is the leading cause of disability and deaths in elderly. If left untreated, the hip fracture results in inability to walk, and therefore the patient is dependent on the other's people help. The aim of this study was to determine the predictive values of the functional status, present comorbidities, and the types of treatment on the long-term functional status and mortality in patients with the hip fracture. MATERIAL AND METHODS We analyzed the data about the patients with the hip fractures treated in the period between 01.07.2006. and 01.07.2016., with the mean follow-up period between 34.3±4.9 months. The data included radiographs, age, comorbidities, functional status on admission, functional status on discharge, and follow-ups. RESULTS Female sex, increasing age, and poorer functional status upon admission, conservative treatment, trochanteric fracture, the presence of neurological or lung disease, diabetes, were all significant risk factors leading to poorer functional outcomes on the latest follow-up (p < 0.05). On the other hand, the patients who were mobile upon admission had a longer survival (38.1±3.51 months) as compared with the other patients (12.3±5.1 months; χ2=25.202, p = 0.001). Besides, the results of this study revealed that the direct, statistically significant relationship exists between the untreated internal and neurological diseases, and increased mortality and poorer functional outcomes on the latest follow-up. CONCLUSIONS These results are useful for the orthopedic and trauma surgeons, who are treating these patients, the physical medicine and rehabilitation specialists, who are performing the rehabilitation of these patients, but also the health policy makers, who may promote the programmes of healthy aging (treating the diseases, maintaining fitness, etc.) Key words: hip fracture; comorbidity; mortality; functional status.
