2064例股骨颈骨折流行病学调查

目的 探讨股骨颈骨折的临床流行病学特征. 方法回顾性分析2003-2007年就诊的所有股骨颈骨折患者,将其按年龄分为儿童组(16岁以下)、青壮年组(16～60岁)和老年组(60岁以上).所有股骨颈骨折根据AO分型,分为31-B1型、31-B2型和31-B3型.对全部患者的性别、年龄、骨折类型、敛伤原因等进行综合性分析. 结果共统计股骨颈骨折2064例,男性971例,女性1093例.2003年356例,2004年381例,2005年397例,2006年454例,2007年476例.儿童组股骨颈骨折74例(3.59%),青壮年组979例(47.43%),老年组1 011例(48.98%).31-B1型960例(46.51%),31-B2型860例(41.67%),31-B3型244例(11.82%). 结论股骨颈骨折逐年上升,老年人所占比例最高,青壮年男性比例高于女性,老年人女性高于男性.儿童组、青壮年组股骨颈骨折AO分型以31-B2型最多,而老年组以31-B1型最多.

Epidemiological analysis of femoral neck fractures in 2064 patients

Objective To investigate the clinical epidemiological features of femoral neck frac-tures. Methods The clinical data of patients with femoral neck fractures admitted to Third Affiliated Hospital of Hebei Medical University from 2003 to 2007 were retrospectively analyzed. All patients were divided into children group (age < 16 years) , adult group (age ranged from 16 to 60 years) and older group (>60 years). The types of the femoral neck fractures included 31-B1, 31-B2 and 31-B3 according to AO classification. The gender, age, fracture type and injury causes were analyzed. Results A total of 2 064 patients (971 males and 1 093 females) with femoral neck fractures were involved in the study.There were 356, 381, 397, 454 and 476 patients respectively in 2003, 2004, 2005, 2006 and 2007.There were 74 patients (3.59%) in the children group, 979 (47.43%) in the adult group and 1 011 (48.98%) in the older group. There were 960 patients (46. 51%) with type 31-B1 fractures, 860 (41. 67%) with type 31-B2 fractures and 244 (11. 82%) with 31-B3 fractures. Conclusions Form 2003 to 2007, the incidence of femoral neck fracture shows a trend of increase, with the highest incidence in the old persons. The male patients with femoral neck fractures are more than female patients in adult group, while the female patients with femoral neck fractures are less than male patients in older group.The dominant fractures type according to AO classification are type 31-B2 fractures in children and adult groups, but type 31-B1 fractures in older group.
