Flow-through fibula flap using soleus branch as distal runoff: a case report.

The flow-through fibula flap utilizing the soleus branch as a distal runoff has not yet been reported. We herein present a patient with left tibial adamantimoma in whom wide resection of the tumor resulted in a segmental tibial defect 22 cm in length. The defect was successfully reconstructed with a flow-through free fibula osteocutaneous flap using the soleus branch of the peroneal artery as a distal runoff. The short T-segment of the peroneal artery was interposed to the transected posterior tibial artery. The soleus branch has a constant anatomy and a larger diameter than the distal stump of the peroneal artery. Short interposed flow-through anastomosis to the major vessels is much easier and more reliable than the conventional methods. We believe that our method represents a versatile option for vascularized fibula bone grafting for extremity reconstruction. © 2012 Wiley Periodicals, Inc. Microsurgery, 2013
