Use of pronator quadratus bone flap in bony reconstruction around the wrist.

Abstract

A bone graft can be raised from the distal end of the radius with intact blood supply derived from a vascular pedicle, i.e., the anterior interosseous artery proximally or the communicating branch from the dorsal carpal plexus distally. This graft has been used to produce proximal radiocarpal fusion, carpal bone replacement, and distal ulnar replacement. This viable graft with excellent blood supply gives very satisfactory clinical results.
