Toe-to-hand vascularized joint transfers in four children were reviewed 6 to 8 years after operation (average, 6.6 years). Two children had vascularized metatarsophalangeal (MTP) joints. Both children have near normal active range of motion. The transferred epiphyses have provided a major contribution to digital growth. The other two children had second toe proximal interphalangeal (PIP) joints transferred to damaged hand joints. Active PIP joint extension has been disappointing, and the overall growth contribution of the transferred epiphysis has been small. We conclude that MTP to metacarpophalangeal vascularized joint transfer can provide painless, functional, stable motion, with near normal growth potential, and the usefulness of toe PIP to hand PIP joint transfer is limited by the inability to achieve good active extension and limited growth potential.
对4例接受趾到手血管化关节移植的儿童进行了术后6至8年（平均6.6年）的随访。2例儿童接受了血管化的跖趾（MTP）关节移植。这2例儿童的关节活动范围接近正常。移植的骨骺对手指生长有重要贡献。另外2例儿童将第二趾近端指间（PIP）关节移植到手部受损关节。PIP关节的主动伸展情况令人失望，移植骨骺对整体生长的贡献较小。我们得出结论，MTP关节至掌指关节的血管化关节移植可提供无痛、功能性、稳定的活动，且具有接近正常的生长潜力，而趾PIP关节至手PIP关节移植的实用性受到无法实现良好主动伸展以及生长潜力有限的限制。
