A congenital bilateral thumb-contracture due to dislocation of both extensor tendons over the metacarpophalangeal joint was treated in a fourteen-year-old boy. Intraoperatively the extensor tendons were shifted to a dorsal position and restrained over the center of the metacarpophalangeal joint of the thumb. By this method the previously useless thumbs were given normal function and cosmetic appearance. This congenital anomaly could not be classified as any known syndrome.
一名14岁男孩因双侧伸肌腱在掌指关节处脱位导致先天性双侧拇指挛缩，接受了治疗。术中，将伸肌腱移位至背侧位置，并固定在拇指掌指关节中心上方。通过这种方法，先前无用的拇指恢复了正常功能和外观。这种先天性异常无法归类为任何已知综合征。
