An Unusual Case of Volar Dislocation of Thumb Metacarpophalangeal Joint: 病例報告—拇指掌指關節掌側脫位的罕見病例

Abstract

Thumb metacarpophalangeal joint dislocation is an uncommon injury. Most of the dislocations are dorsal, and volar dislocation is rare. Only a total of 18 cases of volar dislocation of thumb metacarpophalangeal joint are published in English and other international languages. Successful closed reduction was uncommon. The majority of these volar dislocations required open reduction. In this paper, an unusual case of volar dislocation of the thumb metacarpophalangeal joint that finally required arthrodesis was reported.
