目的 探讨同侧带血管蒂腓骨180°轴向旋转内移术治疗胫骨大段骨缺损的治疗方法和疗效。方法 根据胫骨缺损的长度,切取同侧带血管蒂腓骨并180°轴向旋转内移至胫骨缺损区,将腓骨两端分别插入胫骨髓腔内,远端用螺钉将胫腓骨固定,同时将远端残留腓骨与胫骨融合,预防术后踝关节不稳定。结果 手术治疗16例,经4 个月~19 年随访,骨愈合时间接近正常,踝关节功能无明显障碍。结论 同侧带血管蒂腓骨180°轴向旋转内移术,术式简捷,效果良好,是治疗胫骨大段骨缺损的一种值得推荐的理想方法。
Objective To investigate the treatment and efficacy of ipsilateral vascularized 180 ° axial rotation of the fibula for the treatment of large fragment of tibia. Methods According to the length of the tibial defect, the ipsilateral vascularized fibula was cut off and rotated 180 ° to the tibial defect. The two ends of the fibula were inserted into the medullary canal of the tibia. The distal end was fixed with screws to fix the tibiofibula. Residual fibula and tibial fusion, to prevent postoperative ankle instability. Results Surgical treatment of 16 cases, after 4 months to 19 years follow-up, bone healing time close to normal, no significant obstacle in ankle joint function. Conclusions The ipsilateral vascularized fibular 180 ° axial rotation is an ideal method for the treatment of large fragment of tibia.
