Abstract

Distal radius fractures in the younger population are often comminuted and intra-articular, which can increase the complexity of their management. In addition, these patients tend to place high demands on their wrists, and the prevention of functional arthritis necessitates excellent anatomical reduction. Complicated cases such as these are often limited in their management options. We present a complex case of distal radius fracture and bone loss in which initial therapy with nonvascularized bone graft failed, and osteomyelitis was a further complicating factor. With the aid of preoperative planning with computed tomographic angiography (CTA), a deep circumflex iliac artery (DCIA) bone flap was able to be assessed as a reconstructive option. The use of preoperative CTA, the first description of such imaging in this role, was able to delineate the bone to be harvested, confirm its vascular supply, and plan flap harvest. The use of a vascularized bone flap in this setting was thus undertaken and was able to provide an autologous anatomical support for the wrist while reducing the risk of recurrent infection and still preserving internal fixation. This unique application of the free DCIA bone flap was potentiated by CTA, achieving complete healing and good functional outcomes.
