Vascularized fibula graft for reconstruction after resection of aggressive benign and malignant bone tumors

Abstract

From 1982 to 1991,19 patients at Nara Medical University, Kashihara, Japan, underwent resection of aggressive benign and malignant bone tumors, with limb salvage and reconstruction by free vascularized fibula grafts. The patients were followed up for an average of 54 months. The reconstructed site was the jaw in 6 cases, upper extremity in 3, spine in 1, pelvis in 2, and lower extremity in 7. Six patients had aggressive benign lesions, and 13 had malignant lesions. The sizes of the resultant bone defect ranged from 6 to 20 cm, and the lengths of fibula used ranged from 8 to 24 cm. The average time to union was 4.1 months (2–9 months) in the extremities and pelvis. Local recurrence was observed in 3 cases, for whom vascularized fibula grafts were performed for recurrent tumors. In cases of primary untreated tumors, no recurrences occurred. Therefore, this procedure should be performed at the time of primary operation after extensive resection of an aggressive benign or malignant bone tumor. © Wiley‐Liss, Inc.
