Distal radius reconstruction using a split vascularized fibula. Two cases following giant cell tumor resection

Abstract

We propose a distal radius reconstruction technique that provides a strong stable wrist while preserving mediocarpal range of motion. Two cases of giant cell tumor of the distal end of the radius were treated. The technique included en bloc resection of the lesion followed by wrist reconstruction with partial arthrodesis. A vascularized fibular graft was used. With 4 years of follow-up for patient 1 and 1year for patient 2, range of movement in flexion was, respectively, 20°and 20°; in extension, 20 and 30°; in pronation, 80 and 30°; and in supination, 20 and 15°. Strength reached 68 and 57% of the strength of the opposite side. The time to union of the radial graft and the carpal graft was 2months in both cases. This technique provided cosmetic and functional results matching the results reported in the literature. It increases the reliability of the procedure and the recovery process.
