Twenty seven opponensplasties for ulnar and median paralysis in 25 leprosy patients were performed using extensor indicis proprius. An additional transfer of the radial half of flexor pollicis longus to extensor pollicis longus was done to stabilize the metacarpophalangeal joint of the thumb. The biomechanical aspects of extensor indicis proprius tendon transfer were studied and results evaluated using various anatomical and functional parameters. Extensor indicis proprius provides adequate strength to position the thumb. However, sometimes it does not reach its new insertion. There is no significant deficit at the donor site but in a few cases the index finger may lose its capability for independent extension and sometimes a proximal interphalangeal joint contracture may develop.
对25例麻风病患者的尺神经和正中神经麻痹进行了27次使用示指固有伸肌的对掌肌成形术。另外还将拇长屈肌桡侧半转移至拇长伸肌，以稳定拇指的掌指关节。研究了示指固有伸肌肌腱转移的生物力学方面，并使用各种解剖学和功能参数对结果进行了评估。示指固有伸肌为拇指定位提供了足够的力量。然而，有时它无法到达新的附着点。供区没有明显的功能缺失，但在少数情况下，示指可能会失去独立伸展的能力，有时还可能出现近端指间关节挛缩。
