Objective:To explore the clinical effects of combined medial and lateral malleolus in treating severe fracture of ankle. Methods: From May 2007 to January 2011,89 patients with ankle fracture who underment surgical treatment and had complete follow-up,the data were retrospectively analyzed. In this study,there were 66 males and 23 females with an average age of 30.9 years (ranged, 26 to 62 years). Cause of injury included road accidents in 52 cases, sprains from fall down in 17, construction injury in 16 and other injuries in 4. According to type of Denis-Weber, type A were in 13 cases, type B in 24, type C in 52. Operative technique was as follows. Chosen two-incision of combined medial and lateral malleolus, and reduced lateral malleolus fracture firstly,fixed it with 1/3 tubular armor plate or rebuilt-titanium plate. To chose one or two hollow screws according to the size of fracture block. If fracture of fibula was syntripsis, it can be multi-segmental fixed. If fracture line of posterior malleolus was no more than 1/3 articular surface of ankle or the bone displacement was not serious, it can be disregarded. And if the lesion level was over 1/3, or shift position more than 3 mm, it can be fixed with lag screw after reduction. Either front-to-back or back-to-front fixed direction was OK. At the third day after operation, the patients were instructed to exercise with affected limb,weight training after 6 weeks. Results:Eighty-nine patients were followed up from 6 to 24 months with an average of 16 months. Healing time of the fracture was 10 to 12 months. According to standard of the Baird-Jackson scoring system, 68 cases got excellent results, 18 good and 3 fair. Conclusion; Surgical treatment is quite effective for severe fracture of ankle. It should be chosen correctly according to types of the fracture and degree of ligament injury. At the same time, damage degree of the ligament around the ankle should be considered and properly treated.%目的:探讨内外踝联合手术治疗严重踝关节骨折的临床疗效.方法:回顾性分析2007年5月至2011年1月行手术治疗且有完整随访资料的89例严重踝关节骨折患者,男66例,女23例；年龄26～62岁,平均30.9岁.致伤原因:车祸伤52例,摔倒扭伤17例,施工损伤16例,其他损伤4例.按照Denis-Weber AO分型:A型13例,B型24例,C型52例.手术方法:选择内外踝双切口,先复位外踝骨折,一般用1/3管形钢板或重建钛扳固定,内踝视骨折块大小选择1枚或2枚空心螺钉固定；如果腓骨骨折是多块粉碎骨折,可多段固定.后踝骨折不超过关节面的1/3或移位不大者一般不予处理,若超过关节面1/3或移位超过3mm者,给予复位后拉力螺钉固定,固定方向可从后向前,也可从前向后.术后3d指导患者进行床上功能锻炼,6周左右部分负重.结果:89例均获得随访,时间6～24个月,平均16个月.骨折愈合时间为10～12周.根据Baird-Jackson评分系统进行疗效评定:优68例,良18例,可3例.结论:严重踝关节骨折的手术疗效满意,手术应根据骨折类型进行正确的选择,同时也要考虑周围韧带结构的损伤程度,进行有效处理.
