Abstract
There are many challenges in the successful operative treatment of scaphoid nonunions with foreshortening (“humpback” deformity), carpal collapse, and avascular necrosis (AVN). Scaphoid collapse can be effectively managed with a volar, interposition, structural bone graft. Restoration of scaphoid length also aids in reestablishing carpal height and correcting static carpal instability, such as dorsal intercalated segmental instability (DISI). In the setting of AVN, vascularized bone grafting (VBG) serves to transplant viable osteocytes with delivery of a robust supply of blood. The vascularized free medial femoral condyle (MFC) corticocancellous VBG is a valid surgical option for the treatment of these complicated scaphoid nonunions.
