The literature lacks recent epidemiological studies on the incidence, trauma mechanism and fracture classification of distal femur fractures. The aim of the present study was to provide up-to-date information concerning the incidence of distal femur fractures in a large and complete population and to report on the distribution of fracture classification, trauma mechanisms and patient baseline demographics.
The approach for this study was via a retrospective reviews of records.
A total of 293 patients were treated for 302 distal femur fractures between 2005 and 2010. The mean age at the time of fracture was 62.2 years. The mean age was 44.0 years for males and 71.6 years for females. The gender distribution was 33.4% males and 66.6% females. The overall incidence of distal femur fractures was 8.7/100,000/year. After the age of 60 years, a rapid increase in the incidence of distal femoral fractures was observed in both genders, with a large female predominance. Low-energy injuries were the most common mode of injury in both genders (97%), with approximately 61% being the result of a fall from standing height. AO classification type A (extra-articular fractures) was the most common of all fractures (38.6%). Eighty-four patients (28.7%) were admitted with periprosthetic fractures, corresponding to an overall incidence of periprosthetic fractures of 2.4/100,000/year.
The present study shows an incidence of 8.7/100,000/year of distal femur fractures. After the age of 60 years, a rapid increase in the incidence of distal femoral fractures was observed in both genders, with a considerable female predominance.
目前文献中缺乏关于股骨远端骨折的发病率、创伤机制及骨折分类的近期流行病学研究。本研究的目的是提供关于大量完整人群中股骨远端骨折发病率的最新信息，并报告骨折分类、创伤机制及患者基线人口统计学特征的分布情况。
本研究采用回顾性病历审查方法。
2005年至2010年间，共有293例患者接受了302例股骨远端骨折的治疗。骨折时的平均年龄为62.2岁。男性平均年龄为44.0岁，女性为71.6岁。性别分布为男性33.4%，女性66.6%。股骨远端骨折的总体发病率为8.7/10万/年。60岁以后，男女股骨远端骨折发病率均迅速上升，女性占主导。低能量损伤是男女最常见的损伤方式（97%），其中约61%是从站立高度跌倒所致。AO分类A型（关节外骨折）是所有骨折中最常见的类型（38.6%）。84例患者（28.7%）因假体周围骨折入院，假体周围骨折的总体发病率为2.4/10万/年。
本研究显示股骨远端骨折的发病率为8.7/10万/年。60岁以后，男女股骨远端骨折发病率均迅速上升，女性占相当大的主导地位。
