摘要目的 对比分析东部沿海和西部内陆地区成人股骨颈骨折的流行病学特征. 方法 回顾性分析2010年1月至2011年12月期间东部沿海和西部内陆地区各4家医院诊治的成人股骨颈骨折患者资料,分为3个年龄段:青年(16 ～45岁)、中年(46 ～65岁)、老年(≥66岁).将东部沿海地区4家医院患者资料定为A组,西部内陆地区4家医院患者资料定为B组,对比分析两组患者的性别、年龄、各年龄段骨折例数及骨折Garden分型等. 结果 A组1 251例,B组928例,分别占同期成人股骨近端骨折的50.55％(1 251/2 475)和51.36％ (928/1 807),差异无统计学意义(P＞0.05);分别占同期成人全身骨折的3.29％(1 251/38 060)和2.84％ (928/32 623),差异有统计学意义(P＜0.05).A、B组男女比分别为0.45:1、0.88:1,平均年龄分别为(68.8±16.5)、(64.9±18.2)岁,差异均有统计学意义(P＜0.05).A、B组均为老年患者构成比最高,分别占63.55％、58.19％,差异有统计学意义(P＜0.05).A组青年患者构成比(10.31％)显著低于B组(15.30％),差异有统计学意义(P＜0.05).A、B组高发骨折类型均为GardenⅢ型,构成比分别为60.60％、71.98％,差异有统计学意义(P＜0.05). 结论 东部沿海和西部内陆地区成人股骨颈骨折分别占同期成人股骨近端骨折的50.55％和51.36％,占同期成人全身骨折的3.29％和2.84％.东部沿海地区女性患者比例、平均年龄及老年患者构成比高于西部内陆地区,而青年患者构成比、GardenⅢ型骨折患者构成比低于西部内陆地区.

abstractsObjective To compare epidemiological characteristics of adult femoral neck fractures between the east coast and west inland areas in China from 2010 through 2011.Methods Four hospitals in the east coast area (group A) and 4 hospitals in the west inland area (group B) were selected.The data of adult femoral neck fractures treated between January 2010 and December 2011 at the 8 hospitals were collected through the PACS system and medical records inquiry system.The data were assigned into 3 age groups:young group (from 16 to 45 years),middle-aged group (from 46 to 65 years) and elderly group (≥66 years).Analytic items included gender,age and Garden type.Comparisons were made between groups A and B.Results There were 1,251 adult femoral neck fractures in group A and 928 in group B,accounting for 50.55％ (1,251/2,475) and 51.36％ (928/1,807) of the adult proximal femoral fractures,and 3.29％ (1,251/38,060) and 2.84％ (928/32,623) of all the adult fractures,respectively.There were significant differences between the 2 groups (P ＜ 0.05).The ratio of male to female was 0.45∶1 in group A and 0.88:1 in group B,showing a significant difference (P ＜ 0.05).The average age was 68.8 ± 16.5 years in group A and 64.9 ± 18.2 years in group B,also showing a significant difference (P ＜ 0.05).The elderly group in both groups had the highest proportion of femoral neck fractures (63.55％ in group A versus 58.19％ in group B) but there was a significant difference between the 2 groups (P ＜ 0.05).The prevailing fracture type was Garden type Ⅲ in both groups (60.60％ in group A versus 71.98％ in group B),but there was also a significant difference between the 2 groups (P ＜ 0.05).Conclusions The adult femoral neck fractures in the east coast and west inland areas accounted for 50.55％ and 51.36％ of the adult proximal femoral fractures,and 3.29％ and 2.84％ of all the adult fractures,respectively.The east coast area witnessed higher proportions of female and elderly patients and patients with a higher average age than the west inland area,but lower proportions of young and Garden type Ⅲ patients.
