目的　探讨部分腓骨切除后对儿童供侧肢体功能及形态的影响。方法　对 3～ 12岁患原发性腓骨近端骨巨细胞瘤、胫骨骨折骨缺损及股骨头坏死的儿童共 6 3例 ,经小腿前外侧入路行部分带血管腓骨切取术。术后随访 3～ 10年 ,用踝关节功能测定仪、运动负荷试验、胫腓骨及踝关节X线片测量及评价双侧肢体功能及形态。结果　无一例肢体发育障碍或发生坏死。腓深神经或腓浅神经损伤占 11% ,但多数在术后 3月内自行恢复 ,仅 2例留有持久腓浅神经损伤表现。做运动负荷试验后检查 30例病人中 2例轻度踝疼 ,1例有较明显的踝疼。随患儿身高的增加 ,供骨侧腓骨远近两残端逐渐增长 ,但缺损间隙不变。结论　儿童部分腓骨被切除以后 ,多数供侧肢体无严重并发症。 30例中有 3例踝部疼痛者与腓骨切除较长有关。远期腓骨缺损间隙相对变短 ,这有利于儿童晚期供骨侧踝关节的稳定性 Objective To investigate the effect of partial fibular resection on the function and morphology of lateral limbs in children. Methods A total of 63 children with primary peroneal giant cell tumor of the fibula, tibial fracture and femoral head necrosis aged 3 to 12 years old were treated with vascularized fibular graft via the anterolateral approach of the lower leg. The patients were followed up for 3 to 10 years. The function and morphology of bilateral limbs were measured and evaluated by ankle function test, exercise load test, tibiofibula and ankle joint radiography. Results No case of limb deformities or necrosis. Deep peroneal nerve or peroneal nerve injury accounted for 11%, but most of them recovered within 3 months after surgery, only 2 cases left persistent peroneal nerve injury. After exercise stress test, 30 patients were examined in 2 cases of mild ankle pain, 1 case had a more obvious ankle pain. With the increase of the height of the children, the fibula near the fossa increased gradually from two stumps, but the defect gap remained unchanged. Conclusions After the pediatric part of the fibula is resected, most of the contralateral limbs have no serious complications. Three of 30 patients had ankle pain associated with longer fibula resection. Long-term fibular defect gap is relatively shorter, which is conducive to the stability of children with late lateral bony ankle joint
