Bilateral carpometacarpal joint dislocations of the thumb

Changhoon Jeong et al. Clin Orthop Surg. 2012 Sep.

Abstract

A traumatic carpometacarpal joint dislocation of the thumb accounts for less than 1% of all hand injuries. Optimal treatment strategies for this injury are still a subject of debate. In this article, we report a case of bilateral thumb carpometacarpal joint dislocations: a unique combination of injuries. We believe our case is the second report of bilateral carpometacarpal joint dislocation regarding the thumb in English literature. It was successfully treated with closed reduction and percutaneous K-wires fixation on one side, and an open reduction and reconstruction of the ligament on the other side.

Keywords: Bilateral; Carpometacarpal joint; Dislocation; Thumb.

Intraoperative photographs for the reconstruction of the volar oblique ligament according to the Eaton and Littler technique. (A) Radial half of the flexor carpi radialis (black star) was passed through a drill hole in the base of the first metacarpal bone (MC). (B) It was placed beneath the abductor pollicis longus (white arrow) and then passed around the remaining flexor carpi radialis (white arrow head) and secured over the dorsal capsule.
