Complex dislocations of the metacarpophalangeal (MCP) joint of the hand are uncommon. Most are irreducible by closed means and require open reduction. The structure most frequently blocking reduction is the volar plate, which is often interposed between the metacarpal head and the base of the proximal phalanx by the partially torn deep transverse metacarpal ligaments and MCP collateral ligaments. A review of the literature reveals controversy concerning which surgical approach, dorsal or volar, should be used to reduce these dislocations. We present an unusual case of a closed dorsal complex dislocation of the middle finger MCP joint to advocate the dorsal approach.
手部掌指（MCP）关节的复杂脱位并不常见。大多数无法通过闭合手法复位，需要切开复位。最常阻碍复位的结构是掌板，它常被部分撕裂的掌骨深横韧带和MCP侧副韧带夹在掌骨头和近节指骨基底之间。文献回顾显示，对于应采用背侧还是掌侧手术入路来复位这些脱位存在争议。我们报告一例罕见的中指MCP关节闭合性背侧复杂脱位病例，以支持采用背侧入路。
