A dorsal longitudinal incision provides excellent exposure for reducing complex dislocations of the metacarpophalangeal joints of the thumb and index finger. Within the past four years, we have successfully treated five patients with irreducible dislocations of the metacarpophalangeal joint of the thumb and four with dislocations of the index finger by open reduction through a dorsal incision. This approach exposes the joint and the major structure blocking reduction, the volar plate. The digital nerves, which are tented volarly over the metacarpal head, are not prone to injury and osteochondral fracture fragments can be easily removed from the joint. All of the dislocations were stable following reduction.
背侧纵向切口为复位拇指和示指掌指关节的复杂脱位提供了极佳的暴露。在过去四年中，我们通过背侧切口切开复位成功治疗了5例拇指掌指关节不可复位脱位患者和4例示指脱位患者。这种方法可暴露关节以及阻碍复位的主要结构——掌侧板。在掌骨头上方呈掌侧弓形的指神经不易受伤，并且可以轻松地从关节中取出骨软骨骨折碎片。所有脱位复位后均保持稳定。
