BACKGROUND:Ankle fractures combined with deltoid ligament injury are not uncommon in clinical practice, prone to misdiagnosis and missed diagnosis, resulting in ankle instability, chronic pain and traumatic arthritis. In recent years, because of the research and development of anatomy and biomechanical characteristics of deltoid ligament, the treatment and surgical methods of ankle fracture combined with deltoid ligament injury have progress and development, but it remains controversial. OBJECTIVE:To evaluate the clinical effect of suture anchor repair in the treatment of ankle fracture combined with deltoid ligament injury. METHODS: Twenty-seven patients with ankle fracture combined with deltoid ligament injury were selected between January 2010 and January 2013. The lateral maleolus and posterior maleolus fracture patients were treated with open reduction and internal fixation, and al the deltoid ligament injury patients were treated with anchor repair. The tibiofibular syndesmosis isolated patients received internal fixation with a cancelous bone screw. RESULTS AND CONCLUSION:Al 27 patients were folowed-up for 11-35 months, averagely 23 months. The evaluation according to the American Orthopaedic Foot and Ankle Society score system showed that the excelent and good rate was 74.1%. The results indicate that anchor could perfectly restore the stability of ankle joint.%背景：踝关节骨折合并三角韧带损伤在临床上并不少见，容易发生漏诊及误诊，从而导致踝关节不稳、踝部慢性疼痛及创伤性关节炎。近年来对三角韧带解剖结构和生物力学特征的研究发展，踝关节骨折合并三角韧带损伤的治疗理念和手术方法都有了进步和发展，但仍存在争议。目的：评价带线锚钉治疗踝关节骨折合并三角韧带损伤的临床治疗效果。方法：于2010年1月至2013年1月利用带线锚钉治疗踝关节骨折合并三角韧带损伤27例，对外踝、后踝骨折均行切开复位内固定，利用带线锚钉修复重建三角韧带，对于确定有下胫腓联合分离的患者采用1枚松质骨螺钉固定。结果与结论：所有患者均获得随访，随访时间11-35个月，平均23个月；运用美国足踝骨科协会足踝评分系统对踝关节功能进行综合评估，优良率为74.1%，结果证实，利用带线锚钉可很好地恢复踝关节的稳定性。
