Unilateral pure dislocation of the fifth carpometacarpal joint (CMCJ) is a very rare injury. We are reporting the second case of an ulnar type of unilateral dislocation of a fifth CMCJ. Indian salutation (Namaskar) test and radiographs aid in diagnosis. Closed reduction and internal fixation by K-wires restored the normal anatomic relationships of the fifth CMC joint. This type of injury is prone to be missed in an emergency room due to soft tissue swelling, and particular attention should be paid to diagnose it in polytrauma patients. A review of the literature is presented.
第五掌指关节(CMCJ)的单纯性单侧脱位非常罕见。我们报告了第二例第五掌指关节尺侧型单侧脱位病例。印度问候礼(Namaskar)试验和X线片有助于诊断。克氏针闭合复位及内固定恢复了第五掌指关节的正常解剖关系。由于软组织肿胀,这类损伤在急诊室容易被漏诊,对于多发伤患者应特别注意诊断。现对相关文献进行综述。
