Pisiform bone fracture-dislocation and distal radius physeal fracture in two children.

We report two children with a Salter-Harris type 1 and 2 distal radius physeal fracture associated with a fracture-dislocation of the pisiform bone. The two patients were treated with closed reduction of both the distal radius and dislocated pisiform under general anaesthesia. Then a long-arm cast was applied for 30 days resulting in full healing of the fractures. The patients were re-evaluated after 30 years, and the wrists did not show any functional impairments. On radiographic evaluations, there were no signs of osteoarthritis or misalignment between the pisiform and the triquetral, in contrast to what has been reported in adult carpal fractures.
