OBJECTIVE: The microfracture technique is often considered the standard therapy for treating cartilage defects. The aim of the treatment is the migration of mesenchymal stem cells from the bone marrow into the defect area. However, this regeneration process often results in the formation of fibrocartilage instead of natural hyaline cartilage, due to cellular mechanisms whose causes are not well understood. Therefore, in this study, the differences in bioactivity and apoptosis of fibrocartilage tissue-derived chondrocytes (FCh) obtained by bone marrow stimulation and natural hyaline cartilage tissue-derived chondrocytes (HCh) in the knee joint of rats were compared. METHODS: A total of 24 Wistar albino rats were used in this study, and one hind leg of each animal was operated on, while the other served as a control. A 2-step surgical procedure was performed: First, a microfracture was generated at a 2 mm × 2 mm cartilage defect area in the medial condyle of the femur after a left knee arthrotomy. Second, 6 weeks later, after a double knee arthrotomy, fibrocartilage from the microfracture area of the left knee and 2 × 2 mm of hyaline cartilage from the medial femoral condyle of the right knee were harvested. Chondrocytes were isolated and grouped as HCh or FCh, and cell viability and apoptosis were determined by MTT (4,5-dimethylthiazol -2-yl)-2,5-diphenyltetrazolium bromide) and caspase-3 assays using enzyme-linked immunosorbent assay (ELISA) kits. RESULTS: Fibrocartilage tissue-derived chondrocytes showed similar bioactivity and apoptotic response as HCh under physiological conditions. However, low-dose H2O2 decreased viability (bioactivity) and increased apoptosis in FCh without affecting HCh. High-dose H2O2 reduced the bioactivity of both cell types and induced apoptosis, while the response of FCh to oxidative stress was more aggressive than that of HCh. CONCLUSION: The different response patterns in oxidative stress may provide a basis for understanding the limited survival time of bone marrow-derived fibrocartilage tissue induced by microfractures.

Anterior tibial tuberosity fracture avulsion is an uncommon injury. A concomitant patellar rupture is even more scarcely encountered. We report the case of a 14-year-old male patient who suffered bilateral anterior tuberosity fractures with concomitant bilateral complete patellar tendon rupture. Adolescence, athletic activity, and high BMI may have contributed to this concomitant bilateral injury. Both lesions were treated in a one-stage repair surgery, performing an open reduction and internal fixation of the tibial tuberosity with a cannulated cortical screw and a primary tendon suture following the Krakow technique. To the authors' knowledge, no other cases of bilateral presentation of both lesions have been reported so far in the literature.

The incidence of traumatic spine fractures (TSF) is increasing worldwide, with a reported annual incidence of up to 32.8 per 100000 persons. However, there are only a few cases of spine fractures reported in adolescent idiopathic scoliosis (AIS) patients after posterior spinal fusion (PSF) in the literature. Fractures adjacent to fusion blocks that extend into the lower lumbar spine pose a unique challenge as stabilization of such fractures might require an extension of instrumentation to L5 or the pelvis. We report a novel surgical technique where bilateral pedicle and cortical screws at L4 and supplementary rods that connect the cortical screws to the main rods via dominos were implemented for optimizing the distal anchorage for TSF stabilization following an L3 Chance fracture in an AIS patient who had undergone T4-L2 posterior spinal fusion.

This study aimed to investigate the mid-to-long-term surgical outcomes of open reduction and internal fixation (ORIF) using a hybrid locking plate/cable technique for the treatment of Vancouver type B1 and type C periprosthetic femoral fractures (PPFs) in a consecutive group of patients from a single tertiary referral center. Twenty-five patients (25 PPFs; 17 female, 8 male) in whom a Vancouver type B1 or type C PPF was diagnosed and treated by a hybrid locking plate/cable technique from 2005 to 2016 were included in the study. Patients' functional status was categorized into 4 groups based on the Harris Hip Score (HHS) at the final follow-up: 70=poor result; 70-80=fair; 80-90=good, and 90-100=excellent. Intraand postoperative complications were also recorded. PPF union was defined clinically as the patient's ability to bear full weight with or without assistance and radiographically as the presence of a callus bridging the fracture. Subgroup analyses were conducted according to the Vancouver classification and type of fixation regarding the HHS and time to union. The mean age was 57 ± 16.6 (range, 17-82) years at the time of the primary hip replacement and 64 ± 18.7 (range, 24-88) years at the time of PPF. The mean follow-up was 5.6 ± 3.3 (range, 2-14) years from primary procedure to PPF and 6.5 ± 4.1 (range, 3-15) years following PPF. There were 7 type B1 and 18 type C PPFs. At the final follow-up, the mean HHS was 71 ± 7.74 (range, 57-89). According to HHS, functional results were poor in 8 patients, fair in 14 patients, and good in 3 patients. No major intra- or postoperative complications were noted. Fracture union was achieved in all patients without complications at an average of 13 ± 4.9 (range, 6-24) weeks. In subgroup analysis, while no significant differences were observed in the HHS (P=.87 for the Vancouver type, P=.96 for the type of fixation), time to union differed among groups. Time to union was significantly shorter in type B1 than in type C PPFs (P=.006). Time to union was considerably shorter in the uncemented group compared to the cemented one (P=.017). Adding cables to the locking plate can provide adequate stability to preserve fracture alignment and achieve bony union in Vancouver type B1 and C PPFs. Although union can be achieved by ORIF in such patients, a longer union time may be required for PPFs in the setting of a cemented femoral stem or Vancouver type C. Level IV, Therapeutic study.

The aim of this study was to review the characteristics and classifications of pelvic injuries due to earthquake trauma, to determine the treatment options and outcomes, and to present the experiences of our single trauma center. Sixty patients (23 male, 37 female) who underwent surgical treatment for pelvic ring injuries after the earthquake were analyzed in this study. Demographic data, such as age and gender, operations, and fracture details were recorded. Laboratory results and the amount of blood used were included in the analysis. Fractures were classified according to the Young-Burgess classification. Surgical treatment methods, side of injury, accompanying injuries, and treatment results were analyzed using SPSS software. Left-sided trauma was the most common mechanism of injury, with 36 patients (60%) sustaining left-sided pelvic fractures. Pelvic ring fractures were detected in 78.3% of patients, and combined acetabulum and pelvic ring fractures were identified in 21.7% of patients. Thoracic trauma and extra-pelvic fractures were seen in 12 (20%) and 18 (30%) patients, respectively. Twenty percent of patients underwent emergency abdominal surgery prior to pelvic surgery. Complications were observed in 7 patients (11.6%) in the early period. The average amount of blood used for patients was 2.91 U (min: 0, max: 13 U, SD: 2.66). This study has shown us that lateral compression injuries are more common, and that low hemoglobin levels, high inflammation parameters, previous abdominal surgery, accompanying fractures, and lung injury are the main characteristics of patients with earthquake-related pelvic injuries. It also demonstrates that for the optimal use of materials and implants, experience in different techniques is required, and shows the significant need for blood transfusions in the treatment of these injuries.

Frozen shoulder, a condition characterized by the limitation of active and passive shoulder movements, is predominantly managed conservatively. Corticosteroid injection stands as a widely utilized and effective method for treatment. Nevertheless, the optimal approach for administering the injection remains a subject of controversy. We hypothesized that the injection of corticosteroid through anterior into the extra-articular area would yield superior results than the posterior intra-articular injection. This prospective, randomized, single-blind, and single-center clinical study aimed to compare the therapeutic effectiveness of ultrasound (USG)-guided injection techniques in patients with primary frozen shoulder. We continued the study with 54 patients who met the inclusion criteria. We evaluated patients pre-injection and at the first, third, and sixth weeks after injection. Two distinct approaches were employed: (1) Injection through the anterior extra-articular area around the coracohumeral ligament (CHL), and (2) injection through the posterior route into the glenohumeral joint. Evaluation parameters, including Visual Analog Scale (VAS) scores, active range of motion (ROM), American Shoulder and Elbow Surgeons (ASES) scores, and Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) scores, were assessed pre-injection and at the first, third, and sixth weeks post injection. No significant differences in the demographic and clinical characteristics, laboratory, or radiological findings were observed between the groups. It was observed that both groups exhibited similar and significant improvement in all measured parameters within their respective groups. Regarding pain scores, a notable decrease in VAS scores was observed in both groups (P = .000). There was no difference between the groups in terms of pre-injection VAS, QuickDASH, and ASES scores and active ROM measurements. The study concluded that there was no significant difference between ultrasound-guided injection of posterior intra-articular injection and anterior extra-articular injection concerning pain, ROM, and functional scores. Both techniques can be considered as viable options in the early stage of the disease. Level I, Therapeutic study.

This study aimed to compare the novel Estaş Medical Anodization (EMA) surface treatment technique with the techniques commonly used in the literature and to examine their effects on osteointegration in the rabbit tibia. A total of 24 rabbits used in this study were divided into 3 groups, with 8 rabbits in each group. Using both tibias of all rabbits in the study, screws belonging to the control group were placed in the left tibia, and the right tibia belonging to the experimental group were placed. In the first 8 rabbits, a single experimental group in the right tibia were used; in the second 8 rabbits, 2 different experimental groups in the right tibia were used; and in the last 8 rabbits, 2 different experimental groups in the right tibia were used. Thus, 5 different experimental groups with 8 screws in each group and a separate control group were formed for each of them. EMA-treated surfaces were named 200-800 nm iris oxidation and 800-1200 nm gray oxidation according to the TiO2 layer thickness. Group 1 was implanted with mini-screws prepared with chemical etching+EMA iris oxidation, while group 2 was implanted with sandblasted, large-grit and acid-etched (SLA) mini screws treated with EMA gray oxidation. Group 3 was implanted with mini-screws treated with EMA gray oxidation, group 4 was implanted with mini-screws treated with chemical etching+micro-arc oxidation, and group 5 was implanted with mini-screws treated with chemical etching+EMA gray oxidation. The control group was implanted with mini-screws prepared with pure titanium. At the end of 6 weeks, osseointegration percentages were calculated and compared using histological and scanning electron microscope (SEM) analyses. The histological results confirmed the increase in osseointegration percentages in all experimental groups compared to those that received pure titanium implants (P values control group vs group 1=.005, control group vs group 2, 3, 4, 5=.001). The comparison between the groups revealed that the chemical etching+EMA gray oxidation modification technique (group 5) significantly increased osseointegration compared to the SLA+EMA gray oxidation technique (group 5 vs group 2 P=.016) and the chemical etching+EMA iris oxidation technique (group 5 vs group 1 Pp=.001). The EMA gray oxidation technique (group 3) significantly increased osseointegration compared to the chemical etching+EMA iris oxidation technique (group 1) (group 3 vs group 1 P=.043). The results of the SEM analysis showed that osseointegration was significantly increased in all experimental groups compared to that in the pure titanium (control) group (P values control group vs group 1, 2, 3=.001, control group vs Group 4,5=.006). The mean osseointegration percentage in the experimental groups was the highest in group 5, followed by group 4, group 3 and group 1 equally, and group 2. However, the differences among the experimental were not significant (group 1, group 2, group 3, group 4 vs group 5 P=.408). The EMA titanium surface modification techniques we developed significantly increased osseointegration compared to the pure titanium surface. The EMA gray oxidation technique seems to result in higher osseointegration rates than the EMA iris oxidation technique, and similar rates can be found with the SLA and chemical etching techniques.

This study aimed to investigate the outcomes of Gamma3 nails fitted with U-blade lag screws in the management of combined neck and trochanter fracture of the femur. Two hundred-fifty patients with fractures in the proximal femur underwent treatment using Gamma3 nails integrated with U-blade lag screws from 2015 to 2022. Among these cases, 33 had combined neck and trochanteric fractures; 8 patients were excluded because of follow-up for <1 year. The remaining data of 25 patients (7 males and 18 females) were reviewed. Bone mineral density (BMD), body mass index (BMI), tip-apex distance (TAD), extent of lag screw migration, femoral neck-shaft angle, callus formation, fracture type, and treatment failure were analyzed. The mean patient age was 76.3 (range, 61-91) years, and the mean follow-up duration was 17.3 (range, 12.5-57.3) months. The mean BMD T-scores for the spine and femoral neck were -2.3 ± 1.0 and -2.8 ± 0.7, respectively; 18 patients had T-scores ≤-2.5, indicating osteoporosis. The mean BMI was 23.2 ± 3.8 kg/m2 , and the mean operative time was 69.8 (range, 45-90) minutes. Twenty-one patients experienced injuries from slipping, 2 sustained injuries from falling, and 2 from car traffic accidents. The mean TAD was 21.6 ± 5.9 mm, with 16 patients showing <25 mm. The mean extent of lag screw migration was 5.7 ± 5.1 mm. The mean femoral neck-shaft angle on plain radiographs was 125.1 ± 8.6 degrees immediately postoperatively and 120.3 ± 9.5 degrees at the final follow-up. During the follow-up period, the first callus formation was observed at 3.8 months (range, 1.4-7.3) on plain radiographs in the anteroposterior and axial views. Based on our fracture criteria, 4 patients had a two-part fracture type, 12 patients had three-part, and 9 patients had four-part. Out of 25 patients, 3 exhibited treatment failure. No significant differences were observed between the groups with and without bone union regarding age, BMD, BMI, operative time, TAD of the lag screw, extent of lag screw migration, and femoral neck-shaft angle. The bone union was achieved in 88% of patients who underwent treatment utilizing the U-blade Gamma3 nail for concomitant ipsilateral neck and trochanteric fractures. Level IV, Therapeutic Study.

This study aimed to evaluate the effectiveness and feasibility of the posterior-only approach for debridement, interbody fusion, and internal fixation in treating upper thoracic tuberculosis. This study retrospectively analysed the clinical and radiographic data of 8 patients diagnosed with upper thoracic tuberculosis. All patients underwent posterior approach debridement, interbody fusion, and internal fixation. We conducted pre- and postoperative assessments of the visual analog scale (VAS), Oswestry disability index (ODI) scores, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), ASIA score, and kyphotic Cobb angle. Back pain and lower limb weakness were the most common presenting symptoms. The mean duration of surgery, amount of blood loss, and volume of postoperative drainage were 262.5 ± 43.3 min, 625.0 ± 333.8 mL, and 285.0 ± 118.1 mL, respectively. Patients were followed up for 36 to 48 months. Three months after surgery, there was a significant improvement in VAS and ODI scores, which further improved until the final follow-up. A statistically significant difference was observed between the preoperative and postoperative periods (P < .05). At the final follow-up, lower extremity function had fully returned to normal in all 5 paralyzed patients. The ESR and CRP returned to normal, 18.1 ± 7.3 mm/h and 9.95 ± 5.41 mg/L, respectively, within 3 months postoperatively. There were statistical differences between the preoperative and postoperative periods (P < .05). The average kyphotic correction rate was (71.5 ± 7.3)%, and the average loss of correction angle was (3.5 ± 1.4)°. Intervertebral bone fusion was achieved by all patients within 15 months (mean 8.3 ± 3.2 months) postoperatively. The posterior-only approach seems an effective, safe, and reliable treatment method for upper thoracic tuberculosis, with favourable clinical and radiological outcomes. Level IV, Therapeutic study.

This study aimed to investigate the long-term serum metal ion levels of patients who received metal-on-metal hip resurfacing arthroplasty (MoM HRA). We conducted a retrospective study of 99 patients (110 hips) from March 2006 to May 2017 who underwent MoM HRA. The Harris Hip Score (HHS) and the University of California at Los Angeles (UCLA) activity score were measured, and the patients underwent clinical and radiological management. Serum levels of cobalt (Co), chromium (Cr), and molybdenum (Mo) were measured using inductively coupled plasma mass spectrometry (ICPMS) at 1, 6, and 12 months, and each year follow-up after prosthesis implantation. Patients were followed up from 1 to 156 months, with a mean of 98 months. No complications occurred. Metal ion analysis revealed significantly elevated levels compared to preoperative levels. The metal ions levels increased and reached a peak after surgery, and then the levels began to decline gradually. Approximately 84-108 months after surgery, the metal ion levels increased again to approximately peak levels. Then, up to 156 months after surgery, the metal ions levels will drop approximately to preoperative levels. The serum levels of Cr in women were higher than those in men, with the difference being statistically significant. Patients with a body mass index (BMI) of ≥24.9 kg/m2 Co levels were significantly higher than those of normal-weight patients. The serum levels of metal ions showed no significant differences between the prostheses. The use of the MoM HRA was clinically effective, and the Co, Cr, and Mo levels increased significantly after HRA; however, upon long-term follow-up, serum metal ion levels tended to decrease to preoperative levels. Longer follow-up periods and larger study samples are needed to establish the long-term outcome of patients undergoing HRA with MoM bearings. Level IV, Therapeutic Study.

The term "dyskinesia" has often been used interchangeably with "winging," leading to ambiguity in the literature. To address this, the broader term "scapulothoracic abnormal motion (STAM)" was introduced to describe any abnormal position or movement of the scapula on the chest, resulting in pain and dysfunction. Scapulothoracic abnormal motion has a wide range of causes, including musculoskeletal imbalances such as pectoralis minor hyperactivity, neurological impairments such as long thoracic nerve palsy, and genetic conditions like facioscapulohumeral muscular dystrophy (FSHD). This review aims to identify the different causes and classifications of STAM and to propose a detailed treatment algorithm specifically designed to manage these conditions effectively.

The Quality of Life Profile for spinal deformities (QLPSD) was developed to evaluate the quality of life of patients with scoliosis and other spinal deformities. The purpose of the study was to systematically translate the QLPSD into Turkish and examine the reliability and validity of the Turkish version. This methodological study was conducted with 125 participants with idiopathic scoliosis. After the translation of the QLPSD into Turkish systematically, all participants answered the Turkish version of the QLPSD (T-QLPSD) and Scoliosis Research Society-22 items (SRS-22) questionnaires. Intraclass correlation coefficient (ICC) and Cronbach's α statistics were used to test the reliability of the tools: convergent and construct validity of the tools was assessed using exploratory factor analysis and Pearson's correlation analysis. One hundred twenty-five participants were included in the study. The mean age of them was 13.7 ± 2.2 years. For the T-QLPSD total score, Cronbach's α was 0.91, and the ICC was 0.94. A very good correlation was found between T-QLPSD and SRS-22 total scores (r = -0.71). Participants with mild scoliosis reported less back pain (P = .038), better back flexibility (P=.001), and body image (P=.044) compared to moderate scoliosis. The T-QLPSD was found to be a reliable and valid scale for assessing quality of life in idiopathic scoliotic patients in Türkiye.

Three computed tomography (CT)-based classifications, including Haraguchi, Bartoníček-Rammelt, and Mason-Molloy systems, have been developed to better determine the characteristics of posterior malleolus fractures (PMFs). The aims of this study were (1) to determine the intra- and inter-observer reliability of the computed tomography-based classification systems and (2) to investigate the clinical experience and expertise on their reliabilities. Sixty-seven preoperative ankle CT scans of 67 adult patients with "ankle fracture with the involvement of the posterior malleolus"'' were retrospectively identified. CT images were assessed by 10 observers with different levels of clinical experience from 2 different specialties, including orthopedics and radiology. The observers were asked to classify PMFs according to 3 CT-based classifications on 2 separate occasions with a 4-week interval. Cohen's κ values were measured for 2 raters and Fleiss' κ values were measured for 3 raters and more. Overall, each classification had moderate to very good intraobserver reliability (κ=0.41 to 0.95, P < .01) as well as moderate interobserver reliability for each of the 2 separate assessments (κ=0.41 to 0.60, P < .01 for the first occasion; κ=0.44 to 0.59, P < .01 for the second occasion). Interobserver agreement among the foot and ankle surgeons regarding the Haraguchi and Bartoníček classifications was substantial for both assessment periods, whereas there was a moderate agreement for the Mason classification. Orthopedic residents showed moderate interobserver agreement in each period for both Bartoníček and Mason classifications. Radiology experts illustrated slight and fair agreements in the 2 assessments for Mason classification, moderate agreement in both assessments for Haraguchi classification, and substantial to moderate agreement in the first and second assessments for Bartoníček classification, respectively. Computed tomography-based classification system for PMFs demonstrated moderate interobserver reliability as well as moderate to very good intraobserver reliability. Moreover, foot and ankle specialists exhibit enhanced K values for both inter and intraobserver reliability for each classification system, consistency seems to increase as the interest in the field condenses.

Checkrein deformity of the hallux is commonly characterized by rigid flexion of the interphalangeal joint in ankle dorsiflexion but with flexibility in ankle plantarflexion which can be named as flexion checkrein deformity and as rare condition, extension checkrein deformity, characterized by rigid extension of the first metatarsophalangeal joint in ankle plantarflexion and flexibility in ankle dorsiflexion, has been reported. However, there has not reported coexistence of flexion and extension checkrein deformity. The patient, a 27-year-old male, was referred to our department 3 years after tibial and fibular fractures which was treated by open reduction and internal fixation at a previous hospital. His chief complaint was pain and impaired plantarflexion of the affected great toe. The diagnosis was double checkrein deformity characterized by simultaneous rigidity in both flexion and extension of the hallux due to the adhesion of the flexor hallucis longus (FHL) muscle and the extensor hallucis longus (EHL) tendon after a fracture. Surgical intervention was performed, which involved the transection of the FHL tendon using hindfoot endoscopy and transfer of the EHL to the extensor digitorum longus, resulting in a successful outcome with no postoperative complications. The patient demonstrated a favorable prognosis 2 years after the procedure. This report represents the first documented case of double checkrein deformity and underscores the importance of considering this condition and the potential advantages of surgical intervention.

The purpose of this study was to identify the relationship between scapula morphology and rotator cuff tears (RCT). Hundred seventeen shoulders with and 87 shoulders without RCTs were included in this retrospective study. The critical shoulder angle (CSA) and lateral acromion angle in the coronal view, and the acromial coverage angle (ACA) and coracoid and scapular spine angle (CSSA) in the sagittal view were evaluated using 3-dimensional computed tomography. The glenoid anterior tilt, anterior acromial projection angle (AAPA), coracoid process angle, scapular spine angle (SSA), and inferior angle angle (IAA) with respect to the scapular plane were measured in the sagittal view. In univariate logistic regression analysis, CSA, ACA, AAPA, SSA, and IAA were significantly greater in shoulders with RCTs, whereas CSSA was greater in shoulders without RCTs. In multivariate logistic regression analysis, CSA and IAA were greater in shoulders with RCT and were significantly associated with this condition (P=.00073, P=.0032). This study has shown us that RCTs were associated with a greater curvature of the scapular body and greater CSA and IAA.

We investigated oxidative status in patients with rotator cuff tendinopathy (RCT) and evaluated their relationship with radiological and clinical parameters. In this cross-section study, 88 patients with RCT (59 males and 29 females) and 86 healthy controls (66 males, 20 females) were enrolled. The sample consisted of nontraumatic patients who are suffering from shoulder pain because of rotator cuff disease, which was established by clinical tests and MRI scanning. Oxidative stress in patients with RCT was analyzed via the dynamic thiol/disulfide homeostasis (TDH). Thiol/disulfide homeostasis was measured by a new colorimetric method. Furthermore, oxidative stress was indirectly measured by serum total oxidant status (TOS), oxidative stress index (OSI), and total antioxidant capacity (TAC). Serum disulfide levels and the other oxidative stress parameters of the RCT group were significantly greater than those of the control group (P < .001 for all), whereas the anti-oxidative stress parameters remained unchanged (P > .05 for all). The lowest and highest serum disulfide levels were detected in patients with grades 1 and 3, respectively (P < .001). Furthermore, in a multiple regression analysis, the disulfide/natural thiol ratio (β=-4.886, P = .004) and the MRI grading (β=0.314, P=.001) were independently associated with the Western Ontario Rotator Cuff Index WORC score. We found an association between the levels of various serum markers of oxidative injury, especially serum disulfide levels, and the increasing severity of RCT. Thiol/disulfide homeostasis seems to play a critical role in RCT, both in the beginning and during the progression of disease.

This study aimed to summarize our experience with modified drilling epiphysiodesis and prediction methods for accurate timing of surgery and to compare the results with those of recent work by other authors. The Macnicol and Gupta modified drilling technique was used. Distal femoral and/or proximal tibial permanent epiphysiodesis was performed in 42 children (21 boys, 21 girls; median age at surgery=12.6 years, age range=9.4-15.4 years) between 2004 and 2016. Based on the groundwork of previous studies, we developed an auxological prediction method. The limb length discrepancy (LLD) was assessed by clinical examination and verified by an x-ray of the hips when standing with blocks under the shorter leg. The predicted shortening was 2.7 cm ± 1.1 cm. The final discrepancy after finishing skeletal growth was 0.5 ± 0.5 cm. In 26 patients (61.9%), equalization of both legs was achieved (0-0.5 cm). In 4 patients (9.5%), the remaining shortening was more than 1.0 cm. Shortening of an initially longer leg occurred in two patients (0.5 cm and 0.6 cm). Failure of growth plate arrest was observed in 1 patient. In another 3 patients, the efficacy of tibial epiphysiodesis was unsatisfactory. Minor complications occurred in 5 cases, but there was no evidence of angular deformity in the frontal and sagittal planes or proximal fibula overgrowth. Three patients (7.1%) returned to the operating room. Compared to published data, more patients achieved complete equalization of leg length. The results of this study verified the accuracy of the auxological prediction algorithm of LLD based on Shapiro's findings. The surgical outcome is comparable between Shapiro patterns 1 and 3. Auxological examination, assessment of bone age, and sexual maturation are crucial tools for accurate timing of surgery.

The aim of this study was to evaluate the effects of favipiravir on fracture healing. Forty-eight female rats which had a femur fracture with intramedullary Kirschner wire fixation performed were divided into 6 groups; 2 control groups (C1, C2) and 4 experimental groups (F1, F2, F3, F4). The control groups (C1, C2) received physiological saline by oral gavage for 14 days. Two of the experimental groups (F1, F2) received favipiravir by oral gavage for 5 days, whereas the other groups (F3, F4) received it for 14 days. C1, F1 and F3 groups were sacrificed and evaluated on the 14th day, and C2, F2 and F4 groups were sacrificed and evaluated on the 28th day. The fracture sites were assessed for healing radiologically using the Lane and Sandhu scoring system, and assessed histologically using the Huo et al. scoring system. There was no difference between the groups regarding radiological and histological evaluations made on the 14th day (P > .05, P=.216, respectively). On the 28th day, the radiological scores were found to be significantly higher in the control group when compared to the experimental groups (P < .05). Histologically, the control group demonstrated better fracture healing than the groups that had favipiravir administered (P < .001). This study has shown that favipiravir can have negative effects on fracture healing both radiologically and histologically.

Pediatric bone sarcomas, particularly osteosarcomas, present unique challenges in the realm of orthopedic oncology, given their predilection for the metaphyseal regions of long bones and the intricate balance required between achieving oncologic control and preserving limb function. This abstract encapsulates findings from a comprehensive review aimed at advancing pediatric bone sarcoma care, focusing on navigating the complications and innovating solutions for complications of limb salvage and reconstruction focusing on limb length inequalities and accompanying bone defects. Advancements in imaging, surgical techniques, and adjuvant therapies have shifted the paradigm from amputation to limb-sparing surgeries, albeit with significant challenges, especially in young patients where growth potential complicates reconstructive outcomes. The series highlights the complexity of managing limb length discrepancies (LLD), the cornerstone of limb salvage challenges, and the innovative approaches to address them, including modular endoprosthetic reconstruction with expandable prostheses, magnetic lengthening nails and biological reconstruction strategies like vascularized fibula grafts. This review underlines the importance of a multidisciplinary approach in managing pediatric bone sarcomas, where the aim extends beyond mere survival to ensuring quality of life through functional limb preservation. It highlights the need for ongoing innovation in surgical and reconstructive techniques tailored to the pediatric population's unique needs, emphasizing the potential of emerging technologies and methodologies to improve outcomes. Future research should aim to fill the existing knowledge gaps, particularly in comparing pediatric and adult surgical outcomes, to refine treatment protocols and improve patient care in this challenging domain.
