摘　　要：目的 探讨半腱肌移植修复陈旧性踝关节外侧副韧带损伤及踝关节不稳的有效性.方法 选择陈旧性踝关节外侧副韧带损伤患者2例,其中男1例,女1例;男25岁,女17岁.左侧1例,右侧1例.患者入院前均有2年以上反复踝部旋后位扭伤的病史.踝部损伤为Ⅲ度（美国足踝外科学院分度）;前抽屉试验及距骨倾斜试验阳性.应力X线片显示距骨倾斜平均21°,且在侧位片显示距骨前脱位.2例均采用同侧自体半腱肌肌腱移植重建踝关节外侧副韧带.结果 2例平均随访8个月.患足局部无肿痛,行走正常,踝关节主动活动与被动活动良好,患足前抽屉试验及距骨倾斜试验阴性,应力X线片检查显示距骨无前脱位,距骨倾斜角＜5°.根据Mazur疗效评分标准,优1例,良1例.患者对踝关节功能主观满意.结论 （1）踝关节外侧副韧带损伤是导致慢性踝关节不稳,甚至踝关节骨性关节炎的常见原因;（2）Brostr（o）m法仍不失为修复新鲜踝关节外侧副韧带损伤的有效方法,但对陈旧性损伤无效.（3）采用自体半腱肌肌腱修复重建陈旧性踝关节外侧副韧带的方法简单,有效,对于治疗踝关节不稳、防止踝关节骨性关节炎的发生具有重要的作用.Objective To explore the effectiveness of ipsilateral autologous semitendinosus ten don graft in treatment of lateral ankle ligament injuries and ankle instability. Methods Two patients including one male （25 years old） and one female （17 years old） with chronic lateral instability of the ankle were enrolled in the study. Both patients had the history of repeated ankle sprain in supination position and had grade Ⅲ injury of the lateral ankle ligament according to the American College of Foot and Ankle Surgeons Grading System. Anterior drawer test and talar tilt test were all positive. The stress-inversion radiograph demonstrated the average inclination of the talus for 21 ° and the lateral radiograph demonstrated anterior dislocation of the talus. The chronic ankle instabilities in two patients were treated by using the ipsilateral autologous semitendinosus tendon graft to reconstruct the lateral ankle ligament. Results The two patients were followed up for mean eight months, which revealed that the active and passive range of motion was good, with no pain or swelling. The anterior drawer test and talar tilt test were all negative. The stress-inversion radiograph demonstrated that the average inclination of the talus was less than 5°, with no anterior dislocation of the talus. According to the Mazur grading system, the clinical outcome was excellent in one patient and good in one. The two patients were satisfied with the stability of the ankle. Conclusions （ 1 ） Lateral ankle ligament injury is a common cause of chronic ankle instability,even the ankle osteoarthritis. （ 2 ） Brostr（o）m method can attain satisfactory result for fresh lateral injury of the ankle, but not for the old injuries. （ 3 ） Ipsilateral autologous semitendinosus tendon graft is simpleand effective for treatment of lateral ankle ligament injuries and chronic ankle instability and may play an important role in the treatment of lateral ankle instability and prevention of the occurrence of ankle osteoarthritis.
