Anterior cruciate ligament tears are one of the most frequent soft tissue injuries of the knee. A torn anterior cruciate ligament leaves the knee joint unstable and at risk for further damage to other soft tissues manifested as pain, dislocation, and osteoarthritis. A better understanding of the anatomical details of knee joints suffering anterior cruciate ligament tears is needed to understand and develop prediction models for anterior cruciate ligament injury and/or tear. ⋯ Anterior cruciate ligament injury has been shown to be caused by the forces which act on the ligament. These forces can result from hyperextension of the tibia or the internal rotation of tibia. The anatomical parameters of the knee joint (i.e., notch width index, anterior cruciate ligament width and length) have no role in the cause of an injury.

Wedge effect following intramedullary hip screw fixation of intertrochanteric proximal femur fracture.
The aim of the current study was to determine whether application of an intramedullary hip screw for definitive management of intertrochanteric fracture was associated with post-operative deformity. Specifically this study investigated whether nail insertion would cause a "wedge effect" of the intertrochanteric fracture manifesting as lateralization of the femoral shaft and varus malalignment. ⋯ Despite attention to detail, the application of an intramedullary hip screw for intertrochanteric fracture has the tendency to lateralize the shaft relative to the head/neck segment (The "wedge effect").

A simple and gentle technique for reduction after anterior shoulder dislocation.
Anterior shoulder dislocation (ASD) is a common sports injury. The goal of this study was to evaluate a new procedure for reduction after ASD with respect to success rate, the need for medication for muscle relaxation, sedation, and application of pain medication and put it into context to a systematic literature review. ⋯ The new method is a promising option to popular techniques for reduction of anterior shoulder dislocations. The benefits of this protocol are a gentle and simple application of the procedure as well as an easy acquisition.

Juvenile osteochondritis dissecans of the talus: predictors of conservative treatment failure.
The ideal treatment for juvenile osteochondritis dissecans of the talus (ODT) is still unclear. To determine predictors of failure of conservative treatment, children admitted for ODT were retrospectively analyzed. ⋯ Level III (retrospective comparative study).

Intramedullary nailing of humeral shaft fractures: failure analysis of a single centre series.
Intramedullary nailing (IMN) is an accepted technique for the treatment of humeral shaft fractures. Previous studies published concerns over whether this technique had higher complication rates such as nonunion and technical failures compared to plate osteosynthesis. We, therefore, conducted a single centre failure analysis to critically evaluate our results regarding IMN of humeral shaft fractures. ⋯ IMN is a valid therapeutic option for humeral shaft fractures. Good surgical technique and soft tissue handling are important for good outcome. Currently, patient demands are receiving greater consideration. In an era where early full range of motion and rapid return to work with minimal scarring is mandatory for most patients, the use of IMN will most likely increase in popularity in the future.
