[Volar dislocation of the second and third carpometacarpal joint three months after a fall during a soccer game].

Volar dislocation of the second and third carpometacarpal joint is extremely rare and most often caused by high-energy trauma. In this case a 15-year-old boy fell on his hand while playing soccer. The injury was undiagnosed for three months, perhaps due to an ipsilateral forearm fracture. He was treated with open reduction and Kirchner wire fixation for nine weeks. At two years follow-up he had a painfree hand with a 20% reduction in grip strength.
