BACKGROUND AND PURPOSE
Previous national epidemiological data on the characteristics and trends of patients with ankle fractures have been limited. We therefore analyzed data on Swedish inpatients with ankle fractures in this nationwide population study, based on data from 1987 through 2004.
PATIENTS AND METHODS
Data on all inpatients aged 15 years and older with ankle fracture were extracted from the Swedish National Patient Register for the period 1987-2004.
RESULTS
We identified 91,410 hospital admissions with ankle fracture, corresponding to an annual incidence rate of 71 per 10(5) person-years. During the study period, the number of hospital admissions increased by 0.2% annually, mainly from increase in fracture incidence in the elderly women. Mean age at admission was 45 (SD 19) years for men and 58 (18) for women. The major mechanism of injury was falling at the same level (64%).
INTERPRETATION
This nationwide study of inpatients with ankle fractures showed an increase in fracture incidence, particularly in elderly women.
背景与目的
之前关于踝关节骨折患者特征和趋势的全国性流行病学数据有限。因此，我们基于 1987 年至 2004 年的数据，在这项全国性的人群研究中，对瑞典踝关节骨折住院患者的数据进行了分析。
患者与方法
我们从 1987-2004 年的瑞典全国住院患者登记处提取了所有年龄在 15 岁及以上、患有踝关节骨折的住院患者的数据。
结果
我们共发现 91410 例踝关节骨折住院病例，每年发病率为 71/105 人年。在研究期间，住院人数每年增加 0.2%，主要是由于老年女性骨折发病率的增加。男性的平均入院年龄为 45（标准差 19）岁，女性为 58（18）岁。主要损伤机制为平地跌倒（64%）。
结论
这项关于踝关节骨折住院患者的全国性研究显示，骨折发病率，特别是老年女性的骨折发病率增加。
