[Isolated carpometacarpal dislocation of the thumb: a case report].

The traumatic fracture-dislocation of the first carpometacarpal joint is not frequent, isolated dislocation being even more uncommon. A twenty-five-year-old male patient was diagnosed as having carpometacarpal dislocation of the thumb by means of radiologic and physical examination findings. After immediate reduction, the thumb was immobilized in a short thumb spica cast for six weeks, after which he was enrolled into a rehabilitation program. No pain or instability were found at the end of six months.
