PURPOSE OF STUDY: Inadequate treatment of displaced fractures of the navicular bone may result in malalignment, formation of non-union, accelerated development of osteoarthritis or avascular necrosis and thus a fundamental limitation of mobility and gait disturbance. The aim of our study was to evaluate the results in our group of patients undergoing surgery for navicular fractures. MATERIAL AND METHOD: Our retrospective monocentric study included all surgically treated navicular fractures in patients over 18 years of age performed in our department between 2009 and 2018. A total of 18 patients met these criteria and were invited for clinical and radiographic follow-up. One patient refused to attend and two were lost to follow-up. The remaining 15 patients underwent clinical assessment, including the use of AOFAS midfoot and VAS scores, and the grade of osteoarthritis was determined using radiographs. RESULTS: Our final group of patients consisted of six women and nine men. The mean age of the patients at the time of surgery was 43 (21-67) years, with mean follow-up duration of 68 (18-130) months. The most common mechanism of trauma was high-energy injury occurring in nine of cases. According to the Schmid classification, six fractures were Type I and II each whereas three cases were Type III fractures. Concomitant injuries involving the foot and ankle were present in six cases. All fractures healed.Open reduction and internal fixation (ORIF) was performed in 14 cases. The radiographs showed the presence of osteoarthritis grade 0 or I in nine patients and osteoarthritis grades II and III in six patients. The AOFAS Midfoot scale was excellent and good in eleven cases, satisfactory in two and poor also in two cases. The average AOFAS Midfoot scale was 87.7 points. A procedure-related complication was a case of skin necrosis in a patient eventually undergoing cuneonaviculotalar arthrodesis in another hospital. DISCUSSION: Consistent with literature data, our group showed a higher incidence of concomitant injuries in the foot region. Use of two approaches was not associated with an increased risk of developing avascular necrosis. We do not recommend the use of Kirschner wires for definitive osteosynthesis although we do use them as part of staged treatment or as an additional type of fixation. Like other authors, we observed higher grades of post-traumatic osteoarthritis in the subgroup of patients with more severe injuries. CONCLUSION: Open reduction and stable osteosynthesis of navicular fracture-displacements are associated with good outcomes in most patients. The most serious consequences of these fractures are post-traumatic arthritis and pain. It is critical to search for concomitant injuries. Given the rarity of these fractures, they should be preferably treated in specialised medical centres.

PURPOSE OF THE STUDY: Given the risk of venous thromboembolism (DVT) and pulmonary embolism (PE) after large joint replacement, the role of thromboprophylaxis is crucial. This retrospective study aims to evaluate the effectiveness of aspirin as thromboprophylaxis in patients undergoing TKA or THA. MATERIAL AND METHODS: In this retrospective review of a database of patients who underwent total hip and total knee replacements between 2021 and 2023, we divided patients into two groups: those with no anticoagulation therapy before surgery and those on chronic anticoagulant use prior to surgery. The primary endpoint was the number of patients with complications after aspirin use in the postoperative period. We collected patient demographic information, history of anticoagulant use, postoperative anticoagulant usage, comorbidities, type of surgery, reactions to anticoagulants, complications related to thromboembolism, length of hospital stay, and hospital readmissions. RESULTS: For patients who underwent elective THA or TKA, no significant difference in overall VTE or PE rates was detected when comparing aspirin with other anticoagulants. No mortality events were reported. However, there were differences in bleeding event rates between the aspirin group and other anticoagulant groups. CONCLUSIONS: Proper patient selection and early postoperative mobilization support the use of aspirin as a thromboprophylaxis therapy. The results of this study confirm that aspirin is a safe alternative to other anticoagulants in the postoperative management of THA and TKA.

PURPOSE OF THE STUDY: The study aimed to systematically review the available literature focusing on upper cervical spine injuries in children, namely the age and sex of patients, epidemiology of injuries, classifications used, diagnosis and treatment methods, neurologic deficit, concomitant injuries, and potential complications. MATERIAL AND METHODS: The systematic review was elaborated in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol. The studies assessing pediatric upper cervical spine injuries were searched for in the MEDLINE database in September 2023. The studies included were published between 1991 and 2022. RESULTS: A total of 1354 studies were found through the database search. Subsequently, 53 articles were excluded as duplicates and 1217 due to irrelevant title or abstract. The full text of 84 studies was reviewed. Sixty-nine manuscripts failed to meet the predefined criteria. In the end, the systematic review was based on 15 studies. In the cohort of paediatric patients with upper cervical spine injuries, the girls accounted for 51.1% and boys for 48.9%. X-ray (64.9%) and CT (56.2%) were the most commonly used imaging for diagnosis, with MRI (51.5%) being the least used diagnostic method. Surgical procedure was opted for in treating more than a quarter of cases (27.6%). Most of the surviving patients were neurologically intact (69.2%), a fairly large number of patients (14.4%) died. The most common concomitant injury was craniocerebral trauma (39%) and the most common treatment complication was the instrumentation failure (11.3%). DISCUSSION: Upper cervical spine injuries are rare in children and represent a relatively heterogeneous group. The literature on this topic is mostly inconsistent. Currently, there is just a few studies dealing with pediatric upper cervical spine injuries as a whole; more often the papers focus on a single type of injury. Inconsistencies also occur in defining the age limit for the pediatric spine and in defining the upper cervical spine. For these reasons, comparing the results of individual studies can be difficult. CONCLUSIONS: The mean age of pediatric patients with upper cervical spine injuries was 6.7 years, with a slight predominance of girls. The most common cause of injury was traffic accidents. X-ray and CT were the most commonly used diagnostic methods and surgical therapy was opted for in treating more than a quarter of cases. More than two-thirds of the surviving patients were neurologically intact. Instrumentation failure was the most common treatment complication and craniocerebral trauma was the most common concomitant injury.

PURPOSE OF THE STUDY: Pelvic avulsion fractures in children are rare and usually associated with sports. The study aimed to evaluate the epidemiology, complications, and displacement cutoff value for surgical treatment. MATERIAL AND METHODS: In a retrospective study (2007-2022), we used a group of 201 boys and 20 girls (p < 0.0001). The mean age of boys was 14.9 ± 1.7, and 14.0 ± 1.9 years for girls (p = 0.0129). Injuries included 86 anterior superior iliac spine (ASIS), 83 anterior inferior iliac spine (AIIS), 28 ischial tuberosity (ITU), 13 iliac crest, nine reflected head of the rectus femoris avulsions, and two ipsilateral ASIS + AIIS avulsions. The displacement cutoff value was determined using logistic regression. Complications were assessed using Cox regression and Kaplan-Meier plots. RESULTS: The mean incidence of avulsions was 21 per 1,000,000 children per year. The highest prevalence of osteosynthesis was in ITU (10 out of 28, 35.71%); iliac crest and reflexed head avulsions were treated conservatively. Running was related to the highest risk of ASIS, football for AIIS, and gymnastics for ITU. Most avulsions occurred in September, the fewest in July. Displacement cutoff values were calculated as 10.5 mm for ASIS, 9.5 mm for AIIS, and 14.5 mm for ITU. The most common healing complication was distraction 31 (14.0%), refracture in 2 ITU and non-union in 1 ITU; ITU complications were treated with osteosynthesis. According to the Cox regression, the following items significantly affected outcomes: fracture type (p < 0.0001), early verticalization (p = 0.0062), and initial displacement (p < 0.0001). DISCUSSION: Our study had several limitations, such as it was retrospective, there was a loss of patients from follow-up, and a lack of functional evaluations, for example, using Majeed's score modified for pediatric patients. The positives of the study included a relatively large group of patients from multiple hospitals, the use of logistic regression to determine displacement values to help differentiate between OS and conservative treatment, the inclusion of fracture incidence data, and the inclusion of patients with both surgical and conservative treatment. CONCLUSIONS: In the case of ASIS and AIIS avulsions, osteosynthesis can be considered for displacements ≥ 1 cm and ≥ 1.5 cm for ITU avulsions. Early verticalization was associated with a lower risk of healing complications in distraction injuries.

PURPOSE OF THE STUDY: Open (incisional) biopsies have long been accepted as the gold standard in diagnosing bone and soft tissue tumors. However, the main disadvantage of this method is that it can lead to increased contamination, hematoma, infection, and pathological fracture. Compared to open biopsies, percutaneous core needle biopsies are less invasive, do not require hospitalization, have low costs and low complication rates, and there is no need for wound healing in cases that require radiotherapy. This study evaluated the diagnostic accuracy and reliability of percutaneous core needle biopsy. MATERIAL AND METHODS: The study included the results of 250 percutaneous core needle biopsies of 244 patients who presented at the tertiary university hospital between September 2012 - September 2022 and were diagnosed with a bone or soft tissue tumor using the percutaneous core needle biopsy method and then underwent surgical excision in the Orthopaedics and Traumatology Clinic. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and diagnostic accuracy rates were calculated for the percutaneous core needle biopsy method according to the compatibility of the results. RESULTS: A fluoroscopy-guided percutaneous Jamshidi needle biopsy performed by an orthopedist for lesions originating from the bone has a diagnostic accuracy of 96%. CT-guided percutaneous Jamshidi needle biopsy performed by a radiologist for lesions originating from the bone has a diagnostic accuracy of 88.9%. Percutaneous Tru-cut needle biopsy performed by an orthopedist without imaging guidance for lesions originating from soft tissue has a diagnostic accuracy of 92%. USGguided percutaneous Tru-cut needle biopsy performed by a radiologist for lesions originating from soft tissue has a diagnostic accuracy of 96,7% (p<0.001). DISCUSSION: The diagnostic accuracy of open biopsies ranges from 91% to 99% in the literature. Additionally, the diagnostic accuracy of core needle biopsies in recent studies ranges from 76% to 99%. Compared to the literature, our study has shown that biopsies performed by orthopedic specialists have a high diagnostic power (96% for bone-derived lesions; 92% for soft tissue-derived lesions). CONCLUSIONS: Percutaneous core needle biopsy is highly effective and reliable in diagnosing bone and soft tissue tumors. Managing patients by a team using a multidisciplinary approach will increase diagnostic success. KEY WORDS: core needle biopsy, percutaneous, diagnostic accuracy, radiology guided biopsy, bone and soft tissue tumors.

PURPOSE OF THE STUDY: Lisfranc is a challenging injury both diagnostically and surgically, with sparse long-term literature evidence of surgical practice. We aim to review our long-term specialist orthopaedic institutional experience of Lisfranc injuries and the surgical management of this complex injury, specifically considering surgical outcomes as per radiological and clinical assessment. MATERIAL AND METHODS: We present data from a prospectively maintained institutional database, reviewing patients who underwent operative fixation for Lisfranc injury between April 2014 and August 2020. Patients were referred to our institution from hospitals across the country. We included all operatively managed Lisfranc injuries, primary procedures, and patients over the age of 16. Revision procedures, open injuries, polytrauma patients, patients under the age of 16, and those with multiple foot injuries were excluded. We assessed post-operative results as per the Wilpulla radiographic and clinical criteria. RESULTS: We treated 27 patients across the study period, of mean age 37.5 (SD 18.3), 55% male and 45% female. 33.3% of our patients were obese as defined by body mass index >30. As per the Myerson classification, we had 2 category A, 24 category B, and 1 category C injuries. Time to operation was median 14 days (range 0-116), with 2 delayed presentations following failure of conservative treatment. Our median length of stay was 1 day (range 0-16). We had 3 complications: 2 wound infections and 1 re-operation for non-union. Post-operative assessment as per Wilpulla demonstrated 74% of good, 18.5% fair and 7% poor fixation results. CONCLUSIONS: In our institutional experience, partial congruity lateral displacement injuries were the majority of surgical referrals. Surgical treatment through open reduction and internal fixation delivers good clinical and radiographically anatomical results. Further to conventional mechanisms of injury, we propose obesity to be an important risk factor for indirect, low-energy injuries that may help identify this injury. KEY WORDS: Lisfranc injury, long-term, orthopaedic surgery, obesity.

PURPOSE OF THE STUDY: The aim of this study to evaluate the subjective and objective results of Extensor indicis proprius (EIP) to extensor pollicis longus (EPL) transfer with an emphasis on donor site morbidity. MATERIAL AND METHODS: 17 patients (59% men, 41% women) who underwent EIP-EPL transfer were retrospectively analyzed. The mean age was 43 (9-64) years, and the mean follow-up was 72 (19-124) months. The extensor strengths were measured according to the Medical Research Council (MRC) scoring system. Nail tip-table surface distance (NTD) was measured to evaluate extension loss, and pulp-palm distance (PPD) to evaluate thumb flexion-adduction limitation. Grip and key pinch strengths were measured and corrected regarding the dominance and compared with those of the non-operated side. Quick Disability of Arm, Shoulder, and Hand (QDASH) and satisfaction scores of the patients were evaluated. RESULTS: Donor site morbidity was detected in 6 patients (35%). The extension strength of the index finger was found to be significantly lower than the non-operative side (p<0.05). Thumb mean NTD and PPD values were 6.8 (0-50) and 2.9 (0-20) mm, respectively. The index finger mean NTD was 0.6 (0-10) mm. The grip strength was 86% (43%-100%) and the pinch strength was 82% (31-100%) of the expected strengths. Compared to the preoperative period, there was a significant decrease in the QDASH score (p <0.05). Postoperative QDASH scores of patients with donor site morbidity were significantly higher than those without (p <0.05). CONCLUSIONS: Although patients are generally satisfied with the EIP-EPL transfer results, the permanent morbidity rate in the index finger is high. Therefore, alternatives other than EIP should be considered for transfer to EPL in individuals whose occupation requires complete and strong index finger extension. KEY WORDS: extensor pollicis longus, neglected tendon laceration, extensor indicis proprius, tendon transfer, donor site morbidity.

PURPOSE OF THE STUDY: The annual number of spinal fusion procedures has been increasing and is well documented worldwide. The O-arm is slowly becoming the standard for transpedicular screw insertion. The accuracy and safety of this method have been confirmed by many studies. Therefore, the learning curve of this method and its use by younger surgeons is the focus of our investigation. Longer operative time and radiation exposure to the patient are its only disadvantages. Our aim was to evaluate the learning curve of neurosurgical residents receiving specialist training and to demonstrate the safety and accuracy compared to the conventional C-arm-guided screw insertion used in the surgical management of spondylolisthesis. MATERIAL AND METHODS: Two groups of patients were evaluated - a retrospective cohort composed of patients with degenerative lumbar spinal instability indicated for C-arm-guided posterior transpedicular screw fixation and a prospective group of patients with the same diagnosis and surgical indication for O-arm-navigated screw insertion. In the retrospective group, the surgeons were largely experienced certified spine surgeons and neurosurgeons, whereas in the prospective group there were mainly neurosurgical residents receiving specialist training under the supervision of a certified physician. Both groups underwent a postoperative CT scan to evaluate the pedicle screw malposition using the Grade system and the anatomical plane of malposition. The operative times for both groups were recorded and for the O-arm navigated group a learning curve from the introduction of the method was generated. The values obtained were statistically analysed. RESULTS: A relatively favourable learning curve of the O-arm-navigation was obtained, with operative times approximating the Carm-guided group at two years after the introduction of the method. Safety of the O-arm navigation applied by less experienced surgeons was confirmed through statistically significantly higher accuracy achieved in the O-arm group at the expense of longer operative times. Also, a significantly lower number of significant Grade 2 and 3 malposition was reported in the O-arm group. DISCUSSION: The higher accuracy of transpedicular screw insertion in the navigation method has been confirmed multiple times. In our study, even in the group of less experienced surgeons. The favourable learning curve of neurological residents receiving specialist training is less documented. Time efficiency of the method and its safety when applied by younger surgeons could help make O-arm navigation the new gold standard in spine surgery. The longer operative time, the purchase price of the device, and a relatively higher radiation exposure to the patient continue to be its disadvantages. CONCLUSIONS: Based on the data obtained, a conclusion can be drawn that the O-arm navigation in spine surgery represents a safer and more accurate method for transpedicular fixation compared to the conventional C-arm technique, even when used by less experienced surgeons. In future, we should focus on increasing its time-efficiency. We are convinced that the navigationassisted spinal instrumentation will soon become a necessity for spine surgery centres. KEY WORDS: O-arm, transpedicular fixation, spondylolisthesis, fusion, navigation, learning curve.

PURPOSE OF THE STUDY: Cognitive disorders are common in geriatric surgical patients We conducted a study to evaluate depression and cognitive behavior in geriatric patients undergoing orthopedic surgery. MATERIAL AND METHODS: This descriptive cross-sectional study was conducted at a university hospital in Turkey, involving 262 elderly patients who underwent orthopedic surgeries. Data were collected using The Patient Information Form, Standardized Mini-Mental Test, and Geriatric Depression Scale. RESULTS: The mean score of the Standardized Mini-Mental Test scale of the patients after surgery was 17.97±4.99, mean score of the Geriatric Depression Scale was 6.20±2.78. The study revealed that 85.1% (n=223) of the participants had cognitive impairment and 69.1% (n=181) depressive symptoms. Additionally, cognitive impairment and depressive symptoms increased as age, pain scores, and length of hospital stay increased. Our research also showed that individuals with a history of falls, visual/hearing impairment, malnutrition, use of assistive devices, dependence on others for daily activities, non-educated or single, individuals are more likely to experience geriatric depression and have a higher of cognitive impairment. Additionally, patients who have had hip arthroplasty, have low hemoglobin levels, or have high ASA scores are more prone to cognitive impairment. Cognitive impairment was more common in patients with higher depression scores. CONCLUSIONS: Considering these findings, it is crucial to identify the cognitive disorders and depressive symptoms during their initial hospitalization to prevent or treat them in geriatric patients. Regular monitoring of geriatric patients in orthopedic clinics for symptoms of cognitive status and depression is recommended, and caregivers should be made aware of this issue. KEY WORDS: geriatric patients, orthopedic procedures, cognitive status, depression.

PURPOSE OF THE STUDY: Intraarticular fractures of the distal femur rank among the most severe musculoskeletal injuries. Various treatment options, such as plate osteosynthesis or retrograde nailing, can be employed. This study aims to evaluate the clinical outcomes and complications of intraarticular distal femoral fractures treated with retrograde femoral nail, with particular emphasis on C3 fractures. MATERIAL AND METHODS: Between January 2016 and January 2023, 18 AO/33.C3 fractures were treated with a retrograde femoral nail. Of these, two were classified as 33.C1, eight as 33.C2 and eight as 33.C3. Twelve of the fractures were open. After the initial treatment and stabilizing the patient's overall condition, we proceeded with the definitive osteosynthesis. The first phase involved open reduction and fixation using individual screws to reconstruct the articular surface. The second phase consisted in retrograde nailing with correction of the length, axis and rotation of the femur. The evaluation criteria included: complication rate, number of revisions, knee range of motion, mechanical axis and length of the lower extremity, progression of gonarthrosis, pain level, need of walking support, Lysholm and Tegner Activity Score for functional outcome. RESULTS: Overall, we evaluated the complications and the outcomes of 12 patients (13 fractures). Of these, 8 patients experienced some kind of postoperative complications, primarily insufficient healing or nonunion, which were managed through revision surgery. Plate reosteosynthesis was used in 2 patients who were then excluded from the final clinical evaluation. No cases of deep infection or deep vein thrombosis were reported and no patient required total knee replacement. Seven AO/33.C3 fractures were individually evaluated. The average knee range of motion was nearly 0-93°, maximum flexion was 120°. On average, the lower extremity was 1.6 cm shorter and 7.3° varus to the mechanical axis. Only little progression of gonarthrosis was observed along with low levels of pain. The Lysholm Score ranged between 52 and 84 points (averaging 73.1). The mean Tegner Activity Score was 3.4. All results showed adequate improvement in 33.C2 and 33.C1 groups. DISCUSSION: The retrograde femoral nail demonstrates several advantages over the locking compression plate, particularly in biomechanical aspects. Various clinical studies have reported superior outcomes in terms of healing, complication rate, blood loss and functional outcome. Our study findings align with some of those international studies, particularly in the rate of infectious complications (0%), mean Lysholm Score (79.3 p.) and Tegner Activity Score (4.1). On the other hand, we observed a higher rate of revision surgery (53.8 %), mainly due to evaluating 33.C fractures only. The main advantage of this method lies in complete visualization, leading to better reconstruction of the articular surface coupled with excellent biomechanical properties of the intramedullary nail. CONCLUSIONS: Intraarticular distal femoral fractures pose significant challenges to treatment and frequently lead to permanent damage. The primary treatment goals involve achieving anatomical reposition of the articular surface, stable osteosynthesis, correction of the femoral length and axis and early rehabilitation. Our study demonstrates good clinical outcomes with a relatively low rate of complications. Patients are capable of walking without pain, achieving a good range of motion, returning to their occupations and becoming self-sufficient. Moreover, there were no infectious complications and no significant progression of gonarthrosis. KEY WORDS: retrograde femoral nail, intraarticular distal femoral fracture, functional outcome, complication rate.

PURPOSE OF THE STUDY: Hand enchondromas are benign cartilage bone tumors. Curettage represents the actual gold standard for hand enchondromas. Little has been written about the effectiveness of curettage on hand functionality. MATERIAL AND METHODS: In this retrospective study, we evaluated the effectiveness of curettage and bone grafting on the hand. For each case, we compared the pre-operative and post-operative QuickDASH of the treated limb. The final functional outcome was also evaluated by calculating the affected finger's Total Active Movement (TAM). Complications and local recurrences were recorded. RESULTS: Forty-five cases were included in our study. Fifteen of them had a pathological fracture. The mean pre-operative QuickDASH score was 48.4. No intraoperative complications occurred. After a mean follow-up of 38.1 months, the mean QuickDASH score had decreased to 4.4, and the TAM was optimal or sub-optimal. QuickDASH and TAM were significantly better for those with pathologic fractures before surgery. Only 3 cases (7%) had postoperative complications, and 1 (2%) had a local recurrence. DISCUSSION: Our results prove the effectiveness of curettage and early rehabilitation in increasing and restoring the performances of the treated hands. Our patients experienced a significant improvement in their functionality after surgery, generally passing from a poor to an excellent status. In our cohort, those who had a pathologic fracture before surgery had slightly but significantly worse functional outcomes compared to those who did not suffer pre-operative lesions. CONCLUSIONS: Curettage and early postoperative rehabilitation can lead to good clinical and functional outcomes for hand enchondromas. Patients with pathologic fractures, although slightly exposed to a higher risk of sub-optimal outcomes, can also aim for good post-operative functionality. KEY WORDS: hand, chondroma, QuickDASH, fracture, rehabilitation.

PURPOSE OF THE STUDY: Temporary hemiepiphyseodesis using figure-eight plates is currently one of the main surgical techniques to correct axial deformities of lower limbs in paediatric patients. Comprehensive analysis, correct indication and monitoring of treatment are the basic prerequisites for successful therapy. The aim of the study was to analyse parameters that could become an alternative to standard parameters used nowadays, namely the inserted screw angle (SA), and a new parameter - condylar ratio (CR). MATERIAL AND METHODS: The study included 47 patients treated at the Department of Paediatric Surgery, Orthopaedics and Traumatology at the University Hospital in Brno between 2014 and 2021 and diagnosed with idiopathic bilateral axis deviation of lower limbs, namely genu valgum. After having met the inclusion criteria, the patients underwent a clinical check-up, and long leg radiographs were also obtained. Anthropometric parameters (age, sex, BMI, intermalleolar distance (IMD)), duration of treatment as well as radiographic parameters - mechanical lateral distal femoral angle (mLDFA), mechanical medial proximal tibial angle (mMPTA), SA and CR, and their derived parameters expressing the change per unit time and defined as a rate of correction (r-mLDFA, r-mMPTA, r-SA, r-CR) were recorded. The obtained values were subsequently statistically analysed, namely by comparing the pretreatment and posttreatment values and through correlation analysis. RESULTS: The mean age of the population was 11.4 years, BMI 26.9 and IMD 14.1. The mean duration of treatment in the study population was 13.9 months. A significant difference was established between the pretreatment and posttreatment values of all measured radiographic parameters (p<.05). A significant correlation was identified between r-mLDFA and r-SA (p=.002), while no significant correlation was found between r-mLDFA and r-CA or between r-CA and r-SA (p=.650; p=.884). DISCUSSION: Comprehensive evaluation of the treatment of axial deformities of lower limbs and its optimization are crucial for successful therapy. In addition to the standard mechanical or even anatomical parameters assessing the axis deviation of lower limbs, the authors seek to evaluate also other parameters that may provide a new insight into the deformity or offer additional benefits such as reduced radiation exposure. Such a parameter is for instance the angle of inserted screws in the eight-figure plate system, although there is a difference in opinion among the authors. In our study, we concluded that it is the change in the screw angle that significantly correlates with the mechanical axis of the femur, and thus, under certain circumstances, can become a monitoring parameter. Contrarily, the condylar ratio is a newly introduced quantity which in our study did not show any significant correlation with the mechanical axis of the femur, although a significant change before and after therapy was observed. CONCLUSIONS: A significant correlation was established between the rate of change in screw angle and r-mLDFA, which may, under certain circumstances, serve as a parameter for treatment evaluation, with the advantage of reduced radiation exposure since the assessment requires one scan of the knee joints under loading only. On the other hand, though, no significant correlation was established between the CR as the newly defined parameter and r-mLDFA, which is why it can only be considered as a complementary parameter rather than a decisive one. KEY WORDS: temporary hemiepiphysiodesis, growth plate, genua valga, screw angle, correlation.

PURPOSE OF THE STUDY: The preclinical study aimed to compare the healing of segmental bone defects treated with biodegradable hyaluronic acid and tricalcium phosphate-based hydrogel with the established autologous spongioplasty. Another aim was to evaluate the hydrogel as a scaffold for osteoinductive growth factor of bone morphogenetic protein-2 (BMP-2) and stem cells. MATERIAL AND METHODS: The study was conducted in an in vivo animal model. A standardized rabbit model of a 15 mm long segmental bone defect of left radius was used. A total of 40 animals were divided into 5 groups of 8 individuals. In the KO- (negative control) group, the created defect was left to heal spontaneously. In the KO+ (positive control) group, the defect was filled with morselized bone autograft prepared from the resected segment. In the study group A, the defect was filled with hydrogel based on hyaluronic acid derivative and tricalcium phosphate. In the study group B, the defect was filled with hydrogel based on hyaluronic acid derivative, tricalcium phosphate and bone marrow aspirate. In the study group C, the defect was filled with hydrogel based on hyaluronic acid derivative, tricalcium phosphate, bone marrow aspirate and BMP-2. Healing was assessed using radiographs at 1, 6, and 12 weeks postoperatively and histology specimens were collected at 16 weeks postoperatively. RESULTS: Altogether 35 rabbits survived (KO- 7, KO+ 7, A 7, B 6, C 8) until the end of the study. As concerns the radiographic assessment, the best results were achieved by the groups KO+ and C, where new bone formation across the entire width of the bone defect was clearly seen at 6 and 12 weeks and the osteotomy line was completely healed too. At 12 weeks, complete bone remodelling was observed in all animals in the group KO+, whereas in the group C, bone remodelling was fully completed in 5 animals and partially completed in 3 animals. In terms of histological assessment, however, the best results were achieved by the group C, where the bone defect was completely remodelled into lamellar bone in 7 specimens, while in 1 specimen it healed with bony callus formation. In the group KO+, the defect was healed in 4 specimens by cartilaginous callus with loci of remodelling into bony callus, in 2 specimens the bony callus was predominant with cartilaginous callus areas, and only one defect was completely remodelled into lamellar bone. DISCUSSION: Compared to autografts that manifest osteogenic, osteoinductive and osteoconductive properties, the biodegradable hyaluronic acid and tricalcium phosphate-based hydrogel has osteoconductive properties only. Thus, it was also tested in our study as a scaffold for bone marrow cells and BMP-2 osteoinductive growth factor. Thanks to its semi-liquid properties, the biodegradable hyaluronic acid and tricalcium phosphate-based hydrogel is a promising material for use in 3D printing. CONCLUSIONS: The preclinical study in an in vivo animal model confirmed the beneficial effect of the biodegradable hyaluronic acid and tricalcium phosphate-based hydrogel on the healing of critical-size segmental bone defects. Better healing of these defects was also confirmed for filling composed of hydrogel and BMP-2 osteoinductive growth factor. The benefit of bone marrow aspirate mixed with hydrogel was not confirmed. KEY WORDS: bone defect, non-union, rabbit, hyaluronic acid, calcium phosphate, stem cells, BMP-2, scaffold, bone healing, spongioplasty.

Hallux extensus is a persistent dorsiflexion of the first metatarsophalangeal joint. Apart from many other causes, it can also be caused by contracture of the extensor hallucis longus muscle, in our case resulting from surgical treatment of crural fracture. The authors present the case of a 17-year-old soccer player who sustained a fracture of both shin and calf bone during a soccer match and underwent surgical treatment with intramedullary nailing. While compartment syndrome wasn't observed, a postoperative complication in the form of progressive development of a dynamic type of hallux extensus was reported. The reason behind this complication was later found to be the interaction of the osteosynthesis material with the extensor hallucis longus muscle, which led to its scarring and shortening. A Z-lengthening of the musculus extensor hallucis longus tendon was indicated and performed with a good clinical outcome. During surgery, an anatomical variation in the course of the extensor hallucis longus was observed, which had to be taken into account to achieve a successful surgical outcome. Key words: cock-up big toe deformity, musculus extensor hallucis longus contracture, Z-lengthening tenotomy, crural fracture complication.

PURPOSE OF THE STUDY: Os vesalianum pedis (OVP) is a rare accessory bone of the foot located at the base of the fifth metatarsal bone. It is usually asymptomatic and incidentally seen on radiographs. When symptomatic, it manifests itself with lateral foot pain. OVP, which can become symptomatic as a result of traumatic injuries, can also be confused with fracture. The aim of this study is to determine the prevalence and morphometric characteristics of OVP in the Turkish population. MATERIAL AND METHODS: Radiographic images of 5268 individuals aged 16 years and older (mean 39.65±17.21) who completed ossification of the fifth metatarsal bone were evaluated for OVP. Of the cases included in the study, 44.8% were female and 55.2% were male. The general and sex-based prevalence of OVP was calculated, and morphometric measurements were done. RESULTS: OVP prevalence in the Turkish population was found to be 0.15% regardless of sex. OVP prevalence was calculated to be 0.24% in men and 0.04% in women. CONCLUSIONS: Anatomy, radiology, orthopedics and emergency medicine physicians are frequently encountered with foot disorders in clinical and educational practices. It is important to keep in mind the rare presence of OVP (0.15%), in the preliminary diagnosis. KEY WORDS: os vesalianum pedis, accessory ossicle, foot, radiography.

PURPOSE OF THE STUDY: Intertrochanteric hip fractures in elderly patients are a significant cause of morbidity and mortality, with increasing incidence due to the aging population. Despite advancements in intramedullary nailing (IMN) technology, fixation failure remains a concern. This study aims to evaluate pre-and postoperative radiographic risk factors for varus collapse in geriatric intertrochanteric fractures treated with twin interlocking derotation and compression screw cephalomedullary nail (InterTAN, Smith & Nephew). MATERIAL AND METHODS: This retrospective study included patients over 60 years with AO 31A1 and 31A2 intertrochanteric femur fractures treated with InterTAN at a tertiary referral center from August 2012 to August 2017. Patients with high-energy fractures, AO 31A3 fractures, or those requiring open reduction were excluded. Data on demographics, fracture classification, implant sizes, imaging studies, and follow-up were collected. Radiographic assessments included Chang's medial cortical support concept, tip-apex distance (TAD), calcar-referenced TAD (CalTAD), neck-shaft angles (NSA), and screw placement according to Cleveland zones. Varus collapse was defined as a >5° change in NSA within three months postoperatively. Multivariate logistic regression analysis was used to identify risk factors for varus collapse. RESULTS: The study included 136 patients with a mean age of 79.8 years, of whom 38.2% were male. The early postoperative tipapex distance (TAD) averaged 21.9mm, with 30.1% of patients experiencing varus collapse greater than 5°. Positive medial cortical support (PMCS) or neutral position (NP) type reduction was highly protective against varus collapse (p < 0.001), as well as TAD less than 25mm (p < 0.001). Additionally, the placement of screws in the central-central or central-inferior zones provided a protective effect against varus collapse (p = 0.031). Conversely, having an OTA/AO type A2.2 or A2.3 fracture significantly increased the risk of varus collapse (p = 0.030). Other factors, such as CalTAD and the nail width to medullary canal ratio, did not significantly predict varus collapse (p = 0.831 and p = 0.952, respectively). DISCUSSION: Our findings align with previous studies highlighting TAD and screw placement as critical factors in preventing fixation failure. The protective effect of PMCS or NP reduction and the increased risk associated with OTA/AO type A2.2 and A2.3 fractures are noteworthy. Unlike previous studies, CalTAD was not significantly associated with varus collapse in our cohort. The study underscores the importance of surgical technique and radiographic parameters in optimizing outcomes for elderly patients with intertrochanteric fractures. CONCLUSIONS: In elderly patients treated with InterTAN nails, varus collapse is influenced by fracture type, TAD, reduction quality, and screw placement. Ensuring a TAD <25mm, achieving PMCS or NP reduction, and placing screws in central-central or central-inferior zones are crucial for minimizing varus collapse. These findings highlight the importance of meticulous surgical technique and radiographic assessment in managing intertrochanteric fractures in the elderly. KEY WORDS: hip fractures, intertrochanteric fractures, internal Fixation, geriatrics, cephalomedullary nail.

PURPOSE OF THE STUDY: Osteoarthritis (OA) of the joints of the hand is one of the most common musculoskeletal disorders in the elderly population. It is a complex, degenerative disease affecting all components of the joint. Surgical treatment is indicated when conservative therapy fails. The ultimate solution is arthrodesis of the distal interphalangeal (DIP) joint. Various methods of arthrodesis have been described, ranging from the use of K-wires or compression screw to different types of intra-articular (intramedullary) implants. The aim of this study is to evaluate the surgical outcomes of arthrodesis of the distal interphalangeal (DIP) joint of the fingers using intramedullary implants. MATERIAL AND METHODS: Since 2011, arthrodesis of the distal interphalangeal joint using an intramedullary implant has been performed at our department 97 times in total, in 59 patients. 9 patients (15 cases of arthrodesis) were excluded from the study group due to their failure to complete the questionnaire, 1 female patient died. In the final group, 82 cases of arthrodesis in 49 patients (47 women, 2 men) were evaluated. In 72% of cases, the surgery was performed on the dominant hand. The mean age at the time of surgery was 58 years (median 59 years). The patients were indicated for surgery after the failure of all conservative treatment options. In addition to radiographs, also the hand function and pain were assessed based on the preand postoperative DASH score questionnaires. RESULTS: The surgical outcomes for all implants are satisfactory. In all 82 patients, the surgical wounds healed per primam. In one case, implant extraction was performed due to infection. Another complication was an unhealed fusion and formation of a non-union with minimum pathological mobility (the patient is satisfied with the outcome). In three patients, a fracture at the base of the distal phalanx was observed on postoperative radiographs, which fully healed within 3 months after surgery. The mean DASH score decreased from 41.95 preoperatively to 14.93 postoperatively. The mean time to healing of the arthrodesis observed on radiographs was 9.1 weeks. DISCUSSION: Currently, there are many different types of arthrodesis of the distal interphalangeal joint of the hand. Each method has its pros and cons. Arthrodesis using an intramedullary implant has the advantages of the older methods while minimizing postoperative complications. Our results are comparable to those reported in the foreign literature. CONCLUSIONS: Based on the evaluated outcomes, arthrodesis of the distal interphalangeal joint using an intramedullary implant can be considered valid. It definitely deserves to be included in the portfolio of surgical treatment of osteoarthritis of the DIP joints of the hand. According to our observation, the differences between various types of implants are minimal and their outcomes are comparable to those reported in foreign publications. The pain relief, restored finger function and fusion rate are comparable to, if not better than, those achieved by the older surgical methods. The advantage of this method is mainly easier implantation, fewer complications, and the possibility of implantation without the use of an X-ray image intensifier, which ultimately reduces the cost of surgery. The main disadvantage is the higher purchase price of the implant. KEY WORDS: osteoarthritis, distal interphalangeal joint, arthrodesis.

INTRODUCTION: During the 20th century, the life expectancy increased by 30 years. At the same time, the number of people living longer than that has grown significantly. The aim of this study was to investigate whether total hip or knee arthroplasty (THA or TKA) in patients over 80 years of age does not reduce their life expectancy. MATERIAL AND METHODS: The study examined the data of patients who had undergone THA or TKA between 1994 and 2002 and were older than 80 years at the time of surgery. The study group was divided into a group of patients in whom elective total hip or knee arthroplasty was performed for arthritis and into a group of patients who underwent the same procedure for proximal femur fracture. The investigated parameter was the real survival, which was compared with the life expectancy predicted by the Institute of Health Information and Statistics of the Czech Republic. We also monitored postoperative mortality and postoperative interval after which the life expectancy was no longer reduced. RESULTS: The study included 547 patients. Of whom, 96 patients underwent elective surgery (36%) and 351 patients underwent surgery for intracapsular hip fracture (64%). In the elective surgery group, the survival was longer than the national average: In the 80-84-year group, the median survival was 6.0 years vs. median life expectancy of 5.6 years; in the 85-89-year group, the median survival was 6.3 years vs. median life expectancy of 3.9 years. The fracture surgery group showed a decrease in the life expectancy compared to the national average - in the 80-84-year group, the median survival was 3.5 years vs. median life expectancy of 5.6 years, and in the 85-89-year group, the median survival was 2.9 years vs. median life expectancy of 3.9 years. The likelihood of postoperative mortality was significantly higher in the fracture group than in the elective group (p = 0.05 vs. 0.01), with the difference being the highest in the first 8 weeks after surgery. CONCLUSIONS: Correctly indicated THA or TKA in patients over 80 years of age improves the quality of life of these patients and does not reduce the life expectancy. Intracapsular femoral neck fractures in patients of that age can still be considered as an indication for surgical treatment as a life-saving procedure. KEY WORDS: total hip arthroplasty, total knee arthroplasty, osteoarthritis, hip fracture, life expectancy.

The bone transport technique uses the principle of distraction-osteogenesis and fill bone defects with the aid of an external fixator. In order to evaluate the clinical effect of femoral internal fixation with Ortho-Bridge System after bone transport, 4 patients after femoral bone transport from October 2020 to October 2022 are studied in this paper. Among them, 3 patients ran refracture of femur after removal of the Limb reconstruction system, 1 patient just finish femoral bone transport and request internal fixation. The surgery results show that Ortho-Bridge System can be used in the situation that conventional Locking compression plate and intramedullary nail are not suitable due to anatomical variation after femoral bone transport. Key words: femoral fracture; Ortho-Bridge System; bone transport; postoperative complications of bone transport.

Significant malrotation of the femur after osteosynthesis is a serious complication of treatment and has a number of consequences for the patients and causes deterioration of their quality of life. Therefore, it is necessary to be familiar with intraoperative techniques to control the correct rotation, mostly clinical and radiological, which give us the possibility to minimize rotational errors. In the postoperative period, with even a slight suspicion of malrotation, it is necessary to proceed to its exact verification and, in indicated cases, to perform necessary correction. We recommend one of the CT techniques as a very reliable method, however in younger patients we prefer to use MRI. Early diagnosis of the rotational error and especially its size is essential from the point of view of potential reconstructive surgery, which is then chosen also with regard to the location of the original lesion. Key words: femoral osteosynthesis, limb malrotation, methods of measuring.
