Introduction: Fracture of the lateral tubercle of the posterior process of the talus (Shepherd fracture) is an uncommon injury seen in sport. It is secondary either to indirect trauma on the plantarflexed foot or to high-impact direct trauma. The fracture can be missed with conventional X-rays and therefore advanced imaging methods such as CT scans are usually warranted for management planning. There is a low threshold towards surgical management in the displaced or comminuted case as the delayed functional outcome with conservative treatment is frequently sub-optimal with long-term pain, degenerative changes and non-union. In this regard, recent years saw an increasing interest in the role of minimally invasive approaches for Shepherd´s fracture treatment, such as arthroscopic reduction and internal fixation (ARIF). Case report: We present a case of a 27-year-old white male professional football player from Serbia who had Shepard fracture and successfully managed with arthroscopic osteosynthesis. The technical approach is detailed with posterior ankle arthroscopy offering the advantages of a minimally invasive approach with low morbidity and a rapid return to regular sporting activities. Conclusion: The utilization of the 2-port arthroscopic approach this method enables the direct observation of the articular surface along with the corresponding fracture lines, thereby affording the surgeon the chance to achieve accurate reduction via a minimally invasive soft tissue aperture. We advocate that Arthroscopic reduction and internal fixation (ARIF) is a reliable method for the fixation of Shepherd's fracture in the hands of experienced ankle arthroscopists. © The Author(s) 2024.

This case report provides a history of a female patient with achondroplasia who underwent bilateral total hip arthroplasty (THA) using short femoral stem. On preoperative radiography, a severe bilateral hip osteoarthritis was noted, with deformity of the femoral metaphyses. After THA, the gait pattern improved significantly, the range of motion of both hips increased, and limb length discrepancy was corrected. There was also an improvement in Harris Hip Score value from 65 to 87. In patients with achondroplasia who develop end-stage hip osteoarthritis, there is a unique challenge for arthroplasty surgeons, including implant design, sizing, positioning, and soft-tissue balancing. We believe that the use of short femoral stems might represent an acceptable surgical strategy in the setting of complex changes in femoral anatomy. © 2025 The Authors

Background: The external fixation (EF) Ilizarov method, shown to offer efficacy and relative safety, has unique biomechanical properties. Intramedullary nail fixation (IMN) is an advantageous alternative, offering biomechanical stability and a minimally invasive procedure. The aim of this study was to assess outcomes in patients undergoing tibia fracture fixation, comparing the Ilizarov EF and IMN methods in an early phase of IMN implementation in Serbia. Methods: This was a retrospective study including patients with radiologically confirmed closed and open (Gustilo and Anderson type I) tibial diaphysis fractures treated at the Institute for Orthopedic Surgery “Banjica’’ from January 2013 to June 2017. The following demographic and clinical data were retrieved: age, sex, chronic disease diagnoses, length of hospital stay, surgical wait times, surgery length, type of anesthesia used, fracture, prophylaxis, mechanism of injury, postsurgical complications, time to recovery, and pain reduction. Pain intensity was measured by the Visual Analog Scale (VAS), a self-reported scale ranging from 0 to 100 mm. Results: A total of 58 IMN patients were compared to 74 patients who underwent Ilizarov EF. Study groups differed in time to recovery (p < 0.001), length of hospitalization (p = 0.007), pain intensity at the fracture site (p < 0.001), and frequency of general anesthesia in favor of intramedullary fixation (p < 0.001). A shorter surgery time (p < 0.001) and less antibiotic use (p < 0.001) were observed when EF was used. Additionally, we identified that the intramedullary fixation was a significant predictor of pain intensity. Conclusions: The IMN method offers faster recovery and reduced pain intensity in comparison to EF, while the length of surgery predicted the occurrence of any complication. © 2024 by the authors.

Objective: To test the hypothesis if presence and amount of effusion in the tibiotalar and talocalcaneal joints are associated with an increased risk for severe structural injury in ankle sprains. Methods: A total of 261 athletes sustaining acute ankle sprains were assessed on MRI for the presence and the amount of joint effusion in the tibiotalar and talocalcaneal joints, as well as for ligamentous and osteochondral injury. Specific patterns of injury severity were defined based on lateral collateral ligament, syndesmotic, and talar osteochondral involvement. The presence and the amount effusion (grades 1 and 2) were considered as risk factors for severe injury, while physiological amount of fluid (grade 0) was considered as the referent. Conditional logistic regression was used to assess the risk for associated severe injuries (syndesmotic ligament rupture and talar osteochondral lesions) based on the presence and amount of tibiotalar and talocalcaneal effusions. Results: For ankles exhibiting large (grade 2) effusion in the tibiotalar joint (without concomitant grade 2 effusion in the talocalcaneal joint), the risk for partial or complete syndesmotic ligament rupture was increased more than eightfold (adjusted odds ratio 8.7 (95% confidence intervals 3.7–20.7); p < 0.001). The presence of any degree of effusion in any of the joints was associated with an increased risk for severe talar osteochondral involvement (several odds ratio values reported; p < 0.001), including large subchondral contusions and any acute osteochondral lesion. Conclusion: The presence of tibiotalar and talocalcaneal effusions is associated with an increased risk for severe concomitant structural injury in acute ankle sprains. Key Points: • For ankles exhibiting severe (grade 2) effusion in the tibiotalar joint after sprain, the risk for partial or complete syndesmotic ligament rupture increases more than eightfold. • The presence of effusion in both tibiotalar and talocalcaneal joints is associated with an increased risk for severe ligament injury such as complete ATFL rupture as well as partial or complete syndesmotic ligament rupture. • The presence of effusion in the tibiotalar or talocalcaneal joints after sprain is associated with an increased risk for severe talar osteochondral involvement. © 2019, European Society of Radiology.

Purpose: Tunnel syndromes around the foot and ankle are underrecognized and frequently misdiagnosed nerve entrapments that can significantly impact patients' quality of life. This review aims to provide a comprehensive overview of the etiology, clinical presentation, diagnostic challenges, and management strategies for these syndromes, focusing on the sural nerve, deep peroneal nerve, tibial nerve, medial plantar nerve, and inferior calcaneal nerve. Methods: A thorough literature review was conducted, examining studies and case reports on nerve entrapments in the foot and ankle. The review covers the clinical assessment, differential diagnosis, and treatment options, including conservative and surgical interventions. Results: Tunnel syndromes of the foot and ankle can arise from various causes, including trauma, anatomical variations, repetitive strain, and systemic conditions. Clinical manifestations often include burning pain, tingling, and motor weakness, depending on the affected nerve. Accurate diagnosis relies on a detailed patient history, physical examination, and adjunctive tests such as electrodiagnostic and imaging. Conservative treatments, such as physical therapy, orthotics, and corticosteroid injections, are often effective, while surgical decompression is reserved for refractory cases. Conclusions: Recognizing and diagnosing tunnel syndromes in the foot and ankle is essential for effective management and preventing permanent nerve damage. A systematic approach that integrates clinical evaluation and appropriate imaging can improve patient outcomes. Timely intervention, whether conservative or surgical, is crucial for alleviating symptoms and restoring function. © The Author(s) 2025.

Background: The purpose of this study was to collect all available randomized controlled trials (RCT) on the treatment of open tibial fractures with an external fixator (EF) and intramedullary nailing (IMN) for meta-analysis to provide reliable evidence-based data for clinical decision-making. Material and methods: The systematic review was undertaken in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and AMSTAR (Assessing the Methodological Quality of Systematic Review). An electronic search of PubMed, Cochrane Library, and Web of Science was performed until 1 March 2023 to identify RCTs which compared either IMN or EF to fix the open tibial fracture. Outcome measures were: postoperative superficial and deep infection, time to union, delayed union, malunion, nonunion and hardware failure. In addition, pain and health-related quality of life were evaluated after 3 and 12 months of follow-up. Results: Sixteen publications comprising 1011 patients were included in the meta-analysis. The pooled results suggested that the IMN technique had a lower postoperative superficial infection and malunion rate (RR = 3.56, 95%CI = 2.56–4.95 and RR = 1.96, 95%CI = 1.12–3.44, respectively), but higher hardware failure occurrence in contrast to EF (RR = 0.30; 95%CI = 0.13–0.69). No significant differences were found in the union time, delayed union or nonunion rate, and postoperative deep infection rate between the treatments. Lower levels of pain were found in the EF group (RR = 0.05, 95%CI = 0.02–0.17, p < 0.001). A difference in quality of life favoring IMN after 3 months was found (RR = −0.04, 95%CI = −0.05–0.03, p < 0.001), however, no statistical difference was found after 12 months (RR = 0.03, 95%CI = −0.05–0.11, p = 0.44). Conclusions: Meta-analysis presented reduced incidence rates of superficial infection, malunion, and health-related quality of life 3 months after treatment in IMN. However, EF led to a significant reduction in pain and incidence rate of hardware failure. Postoperative deep infection, delayed union, nonunion and health-related quality of life 12 months following therapy were similar between groups. More high-quality RCTs should be conducted to provide reliable evidence-based data for clinical decision-making. © 2023 by the authors.
