Few data on ankle fractures in China from large multicenter epidemiological and clinical studies are available. The aim of this research was to evaluate the epidemiological features and surgical outcomes of ankle fractures by reviewing 235 patients who underwent ankle fracture surgery at five hospitals in China.
This study included patients who underwent ankle fracture surgery at five Chinese hospitals from January 2000 to July 2009. Age, gender, mechanism of injury, Arbeitsgemeinschaft für Osteosynthesefragen (AO) fracture type, fracture pattern, length of hospital stay and treatment outcome were recorded. Statistical analyses were conducted using SPSS software. The American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot scale, visual analogue scale (VAS), and arthritis scale were used to evaluate outcome.
Of 235 patients with ankle fractures, 105 were male with an average age of 37.8 years and 130 were female with an average age of 47.3 years. The average follow-up period was 55.7 months. There were significant differences in the ratios of patients in different age groups between males and females, and in mechanisms of injury among different age groups. There were also significant differences in the length of hospital stay among different fracture types and mechanisms of injury. In healed fractures, the average AOFAS ankle-hindfoot score was 95.5, with an excellence rate of 99.6%, the average VAS score was 0.17, and the average arthritis score was 0.18. Movement of the injured ankle was significantly different to that of the uninjured ankle. There were no significant differences between AO fracture types, fracture patterns or follow-up periods and AOFAS score, but there were some significant differences between these parameters and ankle joint movements, pain VAS score and arthritis score.
Ankle fractures occur most commonly in middle-aged and young males aged 20 - 39 years and in elderly females aged 50 - 69 years. The most common mechanisms of injury are twisting injuries and falls from a standing height or less. The results of surgical treatment are satisfactory.
中国很少有大型多中心流行病学和临床研究提供有关踝关节骨折的数据。本研究旨在通过对在中国五家医院接受踝关节骨折手术的 235 例患者进行评估，来评估踝关节骨折的流行病学特征和手术结果。
本研究纳入了 2000 年 1 月至 2009 年 7 月在中国五家医院接受踝关节骨折手术的患者。记录年龄、性别、损伤机制、 Arbeitsgemeinschaft für Osteosynthesefragen（AO）骨折分型、骨折类型、住院时间和治疗结果。使用 SPSS 软件进行统计学分析。采用美国矫形足踝协会（AOFAS）踝-后足评分、视觉模拟评分（VAS）和关节炎评分评估疗效。
235 例踝关节骨折患者中，男性 105 例，平均年龄 37.8 岁，女性 130 例，平均年龄 47.3 岁。平均随访时间为 55.7 个月。不同性别患者在不同年龄组的比例、不同年龄组的损伤机制存在显著差异，不同骨折类型和损伤机制的住院时间也存在显著差异。在愈合骨折中，AOFAS 踝-后足评分平均为 95.5，优良率为 99.6%，VAS 评分平均为 0.17，关节炎评分平均为 0.18。受伤踝关节的活动明显不同于未受伤踝关节。AO 骨折分型、骨折类型或随访时间与 AOFAS 评分无显著差异，但与踝关节活动度、疼痛 VAS 评分和关节炎评分有一定差异。
踝关节骨折最常发生在 20-39 岁的中年和青年男性以及 50-69 岁的老年女性中。最常见的损伤机制是扭转伤和从站立或更低的高度跌倒。手术治疗效果满意。
