Ankle Stability After Resection of the Distal Third of the Fibula for Giant-Cell Lesions

Giant-cell tumors and aneurysmal bone cysts involving the lower end of fibula pose special management problems. Excision of the lower end of the fibula in such cases is undertaken reluctantly because it may result in lateral instability of the ankle. Two cases, one of giant-cell tumor and one of aneurysmal bone cyst of the lower end of the fibula, were excised and the lateral ligaments of the ankle and the periarticular tissue were carefully repaired. In both patients the ankle joints were stable two years after the operation.
