To compare the amount of displacement and rigidity at the fracture line under static & dynamic axial loading and torsional stress of conventional cannulated screw (CS), plate screw fixation including inter-fragmentary screw (PL), and talon cannulated compression device or talon screw in other words (TS) in posterior column fracture models. Synthetic hemipelvis bone models presenting a posterior column fracture were used in this study. Group PL, CS, and TS were created with ten bone models prepared for each group for dynamic and static loading tests and another ten for torsional tests. ⋯ Group PL and Group TS exhibited similar behavior in dynamic, static axial loading tests and torsional rigidity. The maximum torque that Group PL could withstand was statistically significantly higher than the other two groups (p <0,001). Talon cannulated screws had promising results in posterior column fractures of the acetabulum, which may decline the need for open surgery for stable fixation.

Review Meta Analysis
A network meta-analysis of multiple modalities for the treatment of complex proximal humeral fractures in older adults.
Four principal treatment modalities are applied to treat complex proximal humeral fractures in older adults: conservative treatment, open reduction internal fixation, hemiarthroplasty, and reverse shoulder arthroplasty. However, among these, the optimal treatment modality has yet to be determined. Therefore, a network meta-analysis was carried out to compare treatment modalities and assess their effectiveness. ⋯ Compared with open reduction internal fixation, reverse shoulder arthroplasty yields better Constant shoulder scores and allows for greater forward flexion and outreach of range of motion of the shoulder joint in complex proximal humerus fractures in older patients. Meanwhile, hemiarthroplasty yields the best visual analogue scale scores and allows for maximum external rotation of the range of motion. However, open reduction with internal fixation remains the preferred clinical treatment for complex proximal humeral fractures in older patients.

Review Meta Analysis
Operative versus non-operative management of primary patellar dislocation: A systematic review and network meta-analysis.
Acute patellar dislocation is a common knee injury in adolescents and adults that is associated with a high incidence of medial patellofemoral ligament (MPFL) injuries. The aim of this network meta-analysis was to compare the different operative and non-operative protocols for the management of primary patellar dislocation (PPD). ⋯ This network meta-analysis demonstrated arthroscopic MPFL repair is the most effective treatment protocol for the management of acute primary patellar dislocation.

Depending on the severity of the injury and the involvement of the soft tissue envelope, clavicle fractures can be treated operatively or non-operatively. In the past, displaced fractures of the clavicle shaft in adults have been treated non-operatively. However, the rate of nonunion following non-operative treatment seems to be higher than previously reported. ⋯ In recent years this has led to a paradigm shift towards an increase of operative fracture treatment. The aim of this review article was to summarize the currently available evidence on the treatment of clavicle fractures. Classifications, indications, and treatment options for different fracture patterns of the medial, midshaft, and lateral clavicles are presented and discussed.

Recent decades have seen marked advances in the quality of clinical orthopaedic trauma research, and with this has come a rise in the number of randomised clinical trials (RCTs) being conducted in orthopaedic trauma. These trials have been largely valuable in driving evidence-based management of injuries which previously had clinical equipoise. ⋯ Most orthopaedic trials lie within a continuum between these designs, with varying degrees of both pragmatic and explanatory features. In this narrative review we provide a summary of the nuances within orthopaedic trial design, the advantages and limitations of such designs, and suggest tools which may aid clinicians in the appropriate selection and evaluation of trial designs.
