title: Treatment of triplane fractures of the head of the proximal phalanx.
abstract: We report the morphology and treatment of 2 cases of a triplane intra-articular bicondylar fracture of the head of the proximal phalanx. Fracture lines in the coronal, sagittal, and transverse planes characterize this fracture, making it highly unstable. Open reduction and internal fixation using two 1.5-mm interfragmentary screws oriented in a dorsal to volar direction resulted in anatomic restoration of the articular surfaces and satisfactory functional results. In 1 case, autogenous cancellous bone graft was harvested from the ipsilateral radial styloid to support the articular fragments.
