[Fracture of the lunatotriquetrum bone in the triquetral part. Case report and review of the literature].
The fusion of the lunate and triquetrum is the most common type of carpal fusion. Fractures of the os lunatotriquetrum are rare and usually occur at the point of union. In our case we found an isolated transverse fracture of the triquetral part of the fused bone without dislocation. In case of non-union, the differential diagnosis of an incomplete fusion must be taken into consideration.
