Abstract

Isolated thumb carpometacarpal joint dislocation is a rare lesion that accounts for less than 1% of all hand lesions.

The authors present two cases of traumatic isolated thumb carpometacarpal joint dislocation. One of them was treated with closed reduction and cast immobilization, and the other was treated with closed reduction, Kirschner-wires pinning, and cast immobilization.

The first patient had a good functional outcome and showed no signs of thumb carpometacarpal instability. The patient treated with Kirschner wires presented signs of clinical instability and radiological subluxation.

Isolated thumb carpometacarpal dislocation is a rare lesion that can cause joint instability, which interferes with the normal function of the hand and can lead to articular degenerative changes.

The best management of this lesion is still controversial, since there is lack of evidence in the literature showing superiority of one treatment over the other.
