[Treatment of benign bone tumor in extremities of children by subperiosteal free fibula graft].

OBJECTIVE: To investigate the way to reconstruct bone scaffold after removal of giant benign bone tumor in extremities of children. METHODS: From June 1995 to October 2000, 6 cases of benign bone tumor were treated, aged 6-14 years. Of 6 cases, there were 4 cases of fibrous hyperplasia of bone, 1 case of aneurysmal bone cyst and 1 case of bone cyst; these tumors were located in humerus (2 cases), in radius (1 case), in femur (2 cases) and in tibia (1 case), respectively. All patients were given excision of subperiosteal affected bone fragment, autograft of subperiosteal free fibula(4-14 cm in length) and continuous suture of in situ periosteum; only in 2 cases, humerus was fixed with single Kirschner wire and external fixation of plaster. RESULTS: After followed up 18-78 months, all patients achieved bony union without tumor relapse. Fibula defect was repaired, and the function of ankle joint returned normal. CONCLUSION: Autograft of subperiosteal free fibula is an optimal method to reconstruct bone scaffold after excision of giant benign bone tumor in extremities of children.
