Reverse Transfer of the Proximal Vascularized Fibula to Reconstruct the Lateral Malleolus: A Case Report and Literature Review.

Abstract

Defects of the lateral malleolus and distal fibula occur occasionally, mainly because of severe trauma or wide resection of fibular neoplasms. These bony defects should be reconstructed to avoid persistent pain and to prevent an abnormal gait induced by ankle instability. Various methods of repair have been developed, including allografting, autologous iliac crest transplantation, scapular apophysis transplantation, and arthrodesis and prosthetic reconstruction. A reverse transfer of the proximal vascularized fibula is also effective. Its morphologic advantage is apparent, and the surgery is simple and direct, with no need for vascular anastomosis. We treated recurrent fibrous dysplasia in the distal fibula of a young male with wide resection and reconstruction using reverse transfer of the proximal, vascularized fibula. At the 6-year follow-up examination, the patient had an American Orthopaedic Foot and Ankle Society ankle-hindfoot score of 100, without any apparent complications. Additionally, we critically reviewed other methods for reconstructing the lateral malleolus and distal fibula and have concluded that reverse transfer of the proximal vascularized fibula compares favorably and could be the treatment of choice.
