Isolated dislocation of the trapezio-metacarpal (TMC) joint of the thumb is an uncommon hand injury.

Ligaments do not only represent the primary source of joint stability, but also set the limits of motion in conjunction with the passive tension of muscles. Therefore their integrity is essential to maintain the static and dynamic stability between the 1st metacarpal bone and the trapezium. The optimal treatment strategy for the acute thumb CMC joint dislocation remains a subject of debate. Closed reduction and cast, closed or open reduction with transfixion with Kirschner wires and reconstruction of ligament and capsulorrhaphy have been performed so far according to joint stability and surgeon├ó┬?┬?s preference..
