To evaluate and present our experience using the expandable nail system for the treatment of acute tibial shaft fractures. ⋯ The expandable nail offers the theoretical advantages of improved load sharing and rotational control without the need for interlocking screws. This study demonstrates satisfactory healing and alignment for the treatment of tibial shaft fractures using this device. However, caution must be exercised when using this nail in cases of significant comminution and in cases where the fracture pattern involves the more proximal or distal aspect of the tibial shaft.

The 2-step closed reduction maneuver was developed to aid in the rarely encountered inferior shoulder dislocation. The maneuver converts the humeral head from an inferior dislocation to an anterior dislocation and then reduces the humeral head into the glenoid. The operator places one hand on the shaft of the humerus and the other hand on the medial condyle. ⋯ Once this is accomplished, the humerus is adducted against the body. The humerus is then external rotated reducing the humeral head into the glenoid. Two cases of inferior shoulder dislocation were closed reduced by using the described technique with minimal analgesia and without a change in the postreduction neurovascular status.

Avascular necrosis (AVN) is one of the most serious complications of femoral neck fractures in children. Variability in the reported rates of AVN and lack of statistical evidence has minimized the prognostic power of individual studies. The purpose of our study was to review our own cases as well as those from the literature in an effort to identify the risk factors for AVN. ⋯ Although several factors may contribute to the development of AVN, our meta-analysis provides statistical evidence that fracture type and age are the most significant predictors.
