Free non-vascularized fibular strut bone graft for treatment of post-traumatic lower extremity large bone loss.

Abstract

Post-traumatic large bone defects of more than 4 cm occur sometimes in open lower extremity fractures. Management of this kind trauma can be a challenge to orthopedic surgeons. We have managed this kind of bone defect by the use of free non-vascularized fibular strut bone grafts (FNVFG) harvested subperiosteally and held by screw fixation of the strut ends to the ends of the bone defect. Ten patients, eight males and two females, with a mean age of 44 years (range 26-76 years) underwent this procedure. The length of defect was 7.0 cm on average (ranging from 4 to 8 cm). Ten grafts (100%) united at both ends within an average of 6 months (range 5-9 months). Nine patients walked independently, and one patient walked with a stick. FNVFG is a simple procedure and a reliable method to bridge huge bone loss due to open fractures of lower extremities successfully in selected cases.
