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.
异指带血管蒂半关节移植理论上可通过组合来自不同手指的完整关节部件并长期维持关节间隙来产生近乎正常的关节。我们在此报告一例极其罕见的异指带血管蒂半关节移植病例，并进行了42年的随访，证明了这种关节重建技术在恢复手部功能方面的持久性。我们患者的结果表明，尽管骨关节炎改变逐渐进展，但即使经过很长一段时间，仍可获得良好的主观结果并维持主动活动范围。诸如移植物固定和关节面一致性等技术因素可能会影响关节面的逐渐退变。
