摘要
目的探讨累及内踝后丘的三踝骨折患者的流行病构成及损伤特征。方法利用图像处娜系统（PACS）和病例查询系统收集2005年1月至2007年6月间收治的成人累及内踝后阡的三踝骨折患并的影像学资料和病历资料。对所有忠栉的性别、年龄段、致伤原凶和骨折AO分型等项日进行统计和综合分析，结果共统计成人累及内踝后丘的三踝骨折66例，占同期三踝骨折总数的21．6％（66／306）。其中男36例（54．5％），女30例（45．5％）；平均年龄41．1岁。不同年龄段男女比率差异无统计学意义（X2=4．2I3，P=0．519），其中16-20年龄段粥女比率最高（3．0：1），60岁以上年龄段男女比率最低（0．4：1）。骨折发病高峰年龄段为41．50岁，占28．8％（19／66）。骨折的AO分型中44-B3．2型发病最高率（75．8％，50／66），44-c1．3型发病最低率（3．0％，2／66）。损伤以扭伤（33．3％，22／66）和摔伤（27．3％，18／66）多见。，结论累及内踝后丘的二三踝骨折是特有的骨折类型，在三踝骨折中占有一定比例，应引起临床医师的重视。此类骨折多发牛于中年人，大部分山低能垃损伤导致。
Objective To investigate the epidemiological and injury features of adult trimalleolar fraetures involving the posterior colliculus of medial malleolus. Methods The imaging and cliuical data were collected of the adult patients with trimalleolar fractures involving the posterior culliculus who had been treated between January 2005 and June 2007 at our hospital. The gender age injury mechanism and AO classification of the patients were analyzed. Results A total of 66 cases of such fractures were identified aecounting fot 21.6% of the total number of trimalleolar fractures （66/306） over the same period. They were 36 men（54.5% ） and 30 women （45.5%）, with an average age of 41. 1 years. There was no significant difference in the ratio of make to fenale between different age groups （X2 = 4. 213, P = 0. 519）, with the highest（3.0：1 ） in the age group of 16 to 20 years and the lowest （0.4：1 ） in the age group of over 60 years. Sueh fraelures mostly occurred in the age of 41 to 50 years, accounting for 28.8%. By the AO classification, the proportiun of 44-B3.2 was the highest（75.8%, 50/66） while that of44-Cl. 3 the lowest （3.0%, 2/66）. The injury was mostly caused by sprain（33.3%, 22/66） and fall （27.3%, 18/66） . Conclusions Or-thopedists should be aware ttlat trimalleolar fractures involving the posterior collieulus of medial malleolus acenunt fur quite a high proportion of trimalleolar ones. Such fractures mostly occur in the middle-aged adults. Most of such fractures are caused t）y low energy iujury.
