Medial Femoral Condyle Microvascular Bone Transfer as a Treatment for Capitate Avascular Necrosis: Surgical Technique and Case Report.

UNLABELLED: Avascular necrosis (AVN) of the capitate is a rare clinical entity for which a variety of treatment options have been described, ranging from immobilization to microvascular bone transfer. Outcomes following medial femoral condyle corticocancellous free flap reconstruction have not been reported for this specific pathology. We present the case of a 16-year-old girl with posttraumatic capitate AVN who was treated with curettage and medial femoral condyle corticocancellous vascularized bone grafting. At 18 months after surgery, the patient remains pain-free and had resumed all activities including lifeguarding by 6 months after surgery. This microsurgical technique, described previously for AVN of the scaphoid and lunate, may be applied in a similar fashion for the capitate with promising clinical results.

TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic V.
