Clinical features and proportion analysis of adult hip fractures at 11 hospitals in Southwest China from 2010 to 2011

目的 分析我国西南地区成人髋部骨折临床特征构成特点.方法 收集2010年1月至2011年12月我国西南地区11家医院诊治的成人髋部骨折资料,回顾性分析其性别、年龄构成及骨折AO分型分布等.结果 共收集2 833例成人髋部骨折病例资料,男性1 340例（47.30％）,女性1 493例（52.70％）,男女比例为1∶1.11,平均年龄为（66±18）岁.高发年龄段为71 ～ 85岁（42.18％,1 195/2 833）,青壮年组（16～＜60岁）844例（29.79％）,老年组（≥60岁）1 989例（70.21％）.青壮年组男性多见（577例,68.4％）,老年组女性多见（1 226例,61.64％）,两组男女性别差异有统计学意义（Х^2=214.001,P＜0.01）.转子间骨折、股骨颈骨折和股骨头骨折比例分别为46.59％、49.74％和3.67％,各类骨折中高发亚型分别为31-A2型、31-B2型和31-C2型.结论 西南地区成人髋部骨折以女性、老年人多见,其中股骨颈骨折最多,其次是转子间骨折,股骨头骨折最少.

Objective To analyze the clinical feature and constituent ratio of adult hip fractures in Southwest China.Methods The data of adult inpatients and outpatients with hip fractures treated between January 2010 and December 2011 in 11 hospitals of the Southwest China were collected and analyzed.The data includes gender,age,age distribution and fracture pattern according to AO classification.Results There were a total of 2 833 adult hip fractures,including 1 340 （47.30%） males and 1 493 （52.70%）females,with a male-to-female incidence ratio of 1 ∶ 1.11 and a mean age of （66 ± 18） years.The highest frequency of hip fractures was seen in the 71 to 85 years age group（42.18%,1 195/2 833）.There were 844 fractures （29.79%） in the young and middle-aged group （16-〈 60 years） and 1 898 fractures （70.21%） in the geriatric group（≥60 years）.Men had a higher rate than women （men：577 fractures,68.4%） in the young and middle-aged group,while women had a higher rate than men （women：1 226fractures,61.64%） in the geriatric group,with a significant difference in the sex distribution between the two groups （Х^2 =214.001,P 〈 0.01）.The proportion of intertrochanteric fracture （type 31-A）,femoral neck （type 31-B） and femoral head fracture （type 31-C） was 46.59%,49.74% and 3.67% respectively.The highest frequency of the sub-type in each fracture type was type 31-A2,type 31-B2 and type 31-C2.Conclusions Women have a higher rate than men in Southwest China.Geriatric patients are more than the young and middle-aged patients.The femoral neck fractures,intertrochanteric fractures and femoral head fractures are in descending orders according to the proportion of the three different hip fractures.
