In the last decade, the sinus tarsi approach (STA) has gained interest over the extensile lateral approach (ELA) in the operative treatment of displaced intra-articular calcaneal fractures (DIACF's), mainly because of the lower rate of surgical site infections (SSIs). However, most studies are small and retrospective. The aim of this study was to evaluate the rate of SSIs of the STA in a large, prospective series of patients and to identify predictors for SSIs. ⋯ This study confirms the low risk of SSI in DIACFs treated via STA. Significant predictors for SSIs were surgery within one week after injury, ASA of 2 or higher and blood loss > 150cc.

Intra-articular fractures of the distal humerus are typically treated with bicolumnar plate fixation. Despite prompt and accurate reduction and fixation, there is a high rate of complications post-surgical fixation. The purpose of this study was to determine the indications, technique, and outcomes of patients who had undergone an elbow release and hardware removal following bicolumnar plate fixation for an intra-articular fracture of the distal humerus. ⋯ It appears safe to remove both plates and to re-intervene relatively early. There is a modest but consistent improvement in flexion-extension arc, and the re-operation rate is low. Although there is a high rate of post-traumatic arthritic change radiographically, TEA was rare, and elbow-based outcome scores were good, although not normal.

Aims The aim of this study was to assess functional outcome, at medium-term follow up, in patients undergoing intra-medullary nailing of tibial shaft fractures, using the supra-patellar approach. Materials and methods The study included patients with intra-medullary nailing, for diaphysial tibia fractures, between March 2013 to August 2015. An initial audit compared short-term functional outcomes at 15 months, between the supra and infra-patellar approaches, using a cohort of 20 patients (10 in each group). ⋯ The initial audit showed that the supra-patellar group had statistically significantly better Oxford and Kujala scores when compared to infra-patellar group (p < 0.05). At 5 years following supra-patellar nailing, the medium-term cohort showed improved outcome scores compared to the infra-patellar group at 1 year (p < 0.01) but showed no difference with the supra-patellar group at 1 year (p value >0.1). Conclusion Our study suggests that patients undergoing supra-patellar tibial nailing have better outcomes at 15 months compared to traditional infra-patellar nailing and more importantly, they continue to do well even at 5 years, despite perceived risks associated with this technique.

Complications related to treatment of long bone fractures still stand as a major challenge for orthopaedic surgeons. Elucidation of the mechanisms of bone healing and development, and the subsequent alteration of these mechanisms to improve outcomes, typically requires animal models as an intermediary between in vitro and human clinical studies. ⋯ We lay out the general procedure for execution of each model, evaluate the practical implications and important advantages/disadvantages of each and describe recent innovations. Furthermore, we explore the applications that each model is best adapted for in the context of the current state of murine orthopaedic research.
