Eight patients underwent middle ray amputation with excision of the whole of the middle metacarpal and careful soft tissue repair. Excision of the base of the middle metacarpal allowed easier approximation of the index and ring rays without the tendency of these fingers to either scissor on finger flexion or to remain slightly apart. Complete removal of the middle metacarpal appears to allow the bases of the index and ring metacarpals to migrate together. The removal of the metacarpal base caused no functional problems and the technique created a good three-finger hand from both a functional and cosmetic point of view.
8例患者接受了中节指骨截肢术,切除了整个掌骨中部,并进行了仔细的软组织修复。切除掌骨中部基底可使示指和环指更容易靠拢,且这些手指在屈曲时不会出现交叉或仍稍有分开的倾向。完全切除掌骨中部似乎能使示指和环指的基底一起移动。切除掌骨基底未引起功能问题,从功能和美观角度来看,该技术创造了一个良好的三指手。
