A complex fracture-dislocation involving the fifth metacarpophalangeal (MCP) joint occurred in a 16-year-old boy approaching skeletal maturity. Roentgenographic examination demonstrated a widened MCP joint and a dorsally displaced Salter-Harris Type III fracture of the metacarpal head. Attempted manipulative closed reduction was unsuccessful. To achieve successful reduction and fixation it was necessary to make a dorsal approach, incise the interposed volar plate longitudinally, and lever it to the anatomic volar position. Successful fixation of the fracture would have been impossible through a volar approach. The Salter-Harris Type III fracture is a surgical problem.
一名接近骨骼成熟的16岁男孩发生了累及第五掌指（MCP）关节的复杂骨折脱位。X线检查显示MCP关节增宽，掌骨头背侧移位的Salter-Harris III型骨折。尝试手法闭合复位未成功。为了成功复位和固定，有必要采用背侧入路，纵向切开插入的掌板，并将其撬至掌侧解剖位置。通过掌侧入路不可能成功固定骨折。Salter-Harris III型骨折是一个手术问题。
