骨膜下游离腓骨移植治疗儿童肢体良性骨肿瘤

目的 探讨儿童巨大良性骨肿瘤切除后骨支架重建的方式。方法 1995年6月～2000年10月，收治骨纤维异常增殖症4例，动脉瘤祥骨囊肿1例，单纯性骨囊肿1例，共6例。年龄6～14岁。其中位于肱骨2例，桡骨1例，股骨2例，胫骨1例。依次采用骨膜下病灶骨节段性切除，骨膜下自体腓骨游离移植，游离腓骨移植长度4～14cm。骨膜原位严密缝合，仅2例肱骨用克氏针单针固定，术后石膏外固定。结果 术后6例随访时间18～78个月。骨膜下游离移植腓骨全部达骨性愈合。骨肿瘤病灶无复发，切除腓骨处腓骨又重新长出。踝关节功能正常。结论 骨膜下游离腓骨移植是治疗儿童良性骨肿瘤，骨支架重建的较好方法。

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.
