Distal Radius Joint Surface Reconstruction Using a Pedicle Pisiform Osteochondral Transfer.

Treatment of a large articular cartilage defect in the distal radius poses a significant challenge to hand surgeons. To reduce the development of secondary degenerative arthritis, restoration of the articular surface is preferable. Pedicle pisiform transfer has been reported as a useful treatment option for Kienböck's disease. We describe a surgical technique involving vascularized pisiform transfer for large cartilage defects after intra-articular distal radius fractures and highlight the vascular supply of the pisiform.
