Intramedullary percutaneous fixation of metacarpal fractures: screw versus connected K-wires.

The purpose of the present study was to determine clinical and radiographic outcomes in patients treated with limited-open retrograde intramedullary headless screw fixation for metacarpal neck and shaft fractures (group I) versus percutaneous antegrade and retrograde intramedullary double pinning linked by a connector (group II). We designed a retrospective comparative study, with the inclusion of two groups (20 patients each) of metacarpal unstable fractures. Both groups showed similar outcomes at the final follow-up, except for extension lag (significantly better in group II) and return to sport (significantly better in group I).

Survival Rate on a 10-Year Follow-Up of Total Wrist Replacement Implants: A 23-Patient Case Series.

 According to current literature, the estimated average survival rate for Remotion, the total wrist implants, is above 90% on an 8-year follow-up. We examined our series of Remotion to calculate its survival rate on a 10-year follow-up.  A total of 23 cases of total wrist implants were reviewed.

Radiographic measurement of the posterior femoral offset is not precise.

Purpose: The posterior femoral offset may significantly impact the final flexion range after total knee arthroplasty (TKA). The purpose of the present study was to compare a conventional, radiologic-based technique with an intra-operative, surgical navigation-based technique for the measurement of posterior femoral offset. The tested hypothesis was that the two measurement techniques produce different results both before and after TKA.
