THE FIBULA-FLEXOR HALLUCIS LONGUS OSTEOMUSCULAR FLAPD. S. Ruch, MD, Assistant Professor; and L. A. Koman, MD, Professor of Orthopaedic SurgeryBowman Gray School of Medicine, Medical Center Boulevard, Winston-Salem, North Carolina 27157-1070, USA. Correspondence should be sent to Dr D. S. Ruch. Limb salvage after loss of bone and soft tissue may require many operations to obtain soft-tissue cover and bony continuity. We describe a fibula-flexor hallucis longus osteomuscular flap which can provide both soft tissue and bone in a single stage. The flap is based on the peroneal vessels and is covered by a split-thickness skin graft. We report the results in five patients with an average bone defect of 8.3 cm and soft-tissue and skin loss. All regained a normal gait on the donor side; four had clinical and radiological union with excellent soft-tissue cover, but one required later amputation due to diffuse coagulopathy. The flap provides free vascularised bone with muscle cover. It has a dependable, long pedicle with minimal morbidity at the donor site, and allows monitoring of the vascularity of the fibular graft.
