手指近端指间关节不可复位纽扣孔样脱位（病例报告）

J Hand Surg Br. 1985 Feb;10(1):100. doi: 10.1016/s0266-7681(85)80030-9.

Dislocations of the proximal interphalangeal joints of the finger rarely present a problem in reduction. However, reduction may be prevented by buttonholing of the joint capsule and volar plate by the head of the proximal phalanx.

手指近端指间关节脱位在复位方面很少出现问题。然而，近端指骨头部可能会穿破关节囊和掌板，从而阻碍复位。
