Forty-Two-Year Follow-Up After Heterodigital Vascularized Hemijoint Transfer: A Case Report.

Heterodigital vascularized hemijoint transfer can theoretically produce a near normal joint by combining intact joint components from different fingers and maintaining the joint space over the long term. We present herein an extremely rare case of heterodigital vascularized hemijoint transfer with a 42-year follow-up, demonstrating the longevity of this joint reconstruction technique for the restoration of hand function. Our patient's outcome indicates that despite the gradual progression of osteoarthritic changes, good subjective results and maintenance of an active range of motion can be acquired even after a long period. Technical factors such as graft fixation and the congruity of the articular surface may influence the gradual degeneration of joint surfaces.
