Lateral radiographs are important for the evaluation of Garden I and II femoral neck fractures. These fractures appear undisplaced in the anteroposterior view, but posterior tilt of the femoral head may still be present in the lateral view. The influence of posterior tilt is, however, debated, which could be caused by the use of non-standardized cross-table radiographs in the conflicting reports. The aim of this bone-model study was therefore to evaluate the influence of the hips position on measurements of posterior tilt. ⋯ The range of posterior tilt measurements for positions of the proximal femur restricted from 10° IR to 40° ER and 0 to 30° flexion, was above the MDC for observer 1, and below the MDC for observer 2. These findings indicate that rotation and flexion affect measurements of posterior tilt, but the influence may be negligible for positions of the injured extremity that are clinically relevant during cross-table lateral radiographs. A larger study that accounts for variations in anatomy and fracture displacement is required to confirm these findings.

To evaluate the outcome and complications of unstable Pauwels type 3 femoral neck fractures treated with a combination fixation of three cannulated screws and a medial buttress plate. ⋯ Union without femoral neck shortening was achieved in 89% of cases. Implant failure was seen in 3 cases and was associated femoral neck shortening. Reduction loss with backing out of the cannulated screws occurred in these cases, and in one case there was also plate and screw breakage. There were no cases of avascular necrosis identified at a mean follow-up was 13.6 months CONCLUSION: At short time follow-up, treatment of Pauwels type 3 femoral neck fractures using cannulated screws combined with medial buttress plate improves the fracture union rate compared to historical series using cannulated screws alone. The method of medial buttress plate augmentation does not appear to increase any implant related complications, including avascular necrosis.

Ankle dislocation without fracture is rare. We used electronic hospital records to determine the incidence of pure ankle dislocation and performed a systematic review of the literature to investigate the occurrence, treatment and outcome of this injury to better inform treating clinicians. ⋯ Pure ankle dislocation is a rare injury. The literature reports that most injuries occur in sports and motor vehicle accidents. The majority of injuries treated with early reduction followed by a short period of immobilisation and functional rehabilitation have good clinical outcomes.

The purpose of this study was to elucidate whether body mass index (BMI), activity level, and other risk factors predispose patients to Achilles tendon ruptures. ⋯ There was no clinically significant difference found in BMI between patients with ruptures and controls. Furthermore, it was found that patients who sustained ruptures were also more likely to be active at baseline than their ankle sprain counterparts.

PEEK radiolucent plate for distal radius fractures: multicentre clinical results at 12 months follow up.
Open reduction and internal fixation (ORIF) with plate and screws represents the recommended treatment for unstable intra-articular distal radius fractures. Although significant progresses in surgical technique have been made, anatomical reconstruction of radio-carpal articular surface still represent a difficult task, especially in multifragmentary fractures. Available PEEK reinforced-carbon fiber composite radiolucent devices allow both an easier and more careful assessment of intra-operative reduction of the articular surface of distal radius and prompt correction of any residual step deformity. ⋯ PEEK reinforced-carbon fiber composite radiolucent plate represents a useful device for treatment of complex distal radius fractures in the adult population. It possesses unique biomechanical properties and allows for an easier anatomical reduction during surgical intervention.
