对 4例四肢长骨骨纤维异常增殖症伴有病理性骨折的患者进行彻底病灶切除后 ,采用带血管蒂的双腓骨串联、双腓骨合并移植治疗肿瘤切除造成的长段骨缺损 ,以加速骨愈合 ,早期恢复肢体功能。随访 1～ 2年 ,移植的双腓骨在 6个月内达到骨性连接 ,双侧肢体等长 ,对负重无明显影响 ,功能接近正常。说明该方法对治疗四肢骨良性肿瘤切除后遗留的长段骨缺损是有效的 Four patients with long bone and fibrous dysplasia accompanied with pathological fracture of limbs were completely excised. Two long fibulas with vascularized pedicle were used in combination with double fibula transplantation for the treatment of long segmental bone defects caused by tumor resection to accelerate bone healing Early recovery of limb function. Followed up for 1 to 2 years, the transplanted biflambons reached the osseous connection within 6 months, the bilateral limbs were equal in length, had no significant effect on the weight bearing, and the function was close to normal. This method is effective in treating long segmental bone defects left after benign tumor resection of the limbs
