Supplemental graft fixation for distal radius vascularized bone graft.

Abstract

Vascularized bone grafts from the distal radius have been used successfully for the treatment of scaphoid nonunions. Typically, the harvested graft is secured into the scaphoid with a press-fit technique. This type of fixation may lead to graft extrusion in the early postoperative period, and thus to treatment failure. In this technical note, we describe the use of micro bone suture anchors for supplemental fixation of the vascularized bone graft into the scaphoid. It is a simple and quick technique and provides an enhanced fixation of the vascularized bone graft, which is beneficial during the early critical period of bone healing.
