Treatment of triplane fractures of the head of the proximal phalanx

We report the morphology and treatment of 2 cases of a triplane intra-artic ular bicondylar fracture of the head of the proximal phalanx. Fracture line s in the coronal, sagittal, and transverse planes characterize this fractur e, making it highly unstable. Open reduction and internal fixation using tw o 1.5-mm interfragmentary screws oriented in a dorsal to volar direction re sulted in anatomic restoration of the articular surfaces and satisfactory f unctional results. In 1 case, autogenous cancellous bone graft was harveste d from the ipsilateral radial styloid to support the articular fragments. ( 1 Hand Surg 1999;24A:1263-1268.
