Ligament contribution to patterns of articular fractures of the distal radius.

Purpose: Intra-articular fractures of the distal radius are common injuries, but the correlation between ligament attachments and fracture location is poorly understood. The purpose of this study was to assess the location of intra-articular fractures compared to the known ligament attachments of the distal radius.

Methods: The authors retrospectively reviewed computed tomography scans of acute intra-articular distal radius fractures performed at 1 institution between 2001 and 2008.

Cement-within-cement stem exchange using the collarless polished double-taper stem.

The clinical and radiographic outcomes of the cement-within-cement femoral stem exchange technique at revision hip arthroplasty were determined. Twenty-three revisions with a collarless polished double-taper stem design were prospectively monitored at up to 12 years. The most common indications for revision were recurrent dislocation and acetabular revision.
