OBJECTIVE: To analyze the clinical feature and constituent ratio of adult @entity173 in Southwest China. METHODS: The data of adult inpatients and outpatients with @entity173 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 @entity174 pattern according to AO classification. RESULTS: There were a total of 2 833 adult @entity173 , 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 @entity173 was seen in the 71 to 85 years age group (42.18%, 1 195/2 833). There were 844 @entity174 (29.79%) in the young and middle-aged group (16-<60 years) and 1 898 @entity174 (70.21%) in the geriatric group (>= 60 years). @entity1 had a higher rate than @entity1 ( @entity1 : 577 @entity174 , 68.4%) in the young and middle-aged group, while @entity1 had a higher rate than @entity1 ( @entity1 : 1 226 @entity174 , 61.64%) in the geriatric group, with a significant difference in the sex distribution between the two groups (  (2) = 214.001, P<0.01). The proportion of intertrochanteric @entity174 (type 31-A), femoral neck (type 31-B) and femoral @entity174 (type 31-C) was 46.59%, 49.74% and 3.67% respectively. The highest frequency of the sub-type in each @entity174 type was type 31-A2, type 31-B2 and type 31-C2. CONCLUSIONS: @entity1 have a higher rate than @entity1 in Southwest China. Geriatric @entity1 are more than the young and middle-aged @entity1 . The @entity2249 , intertrochanteric @entity174 and @entity3330 are in descending orders according to the proportion of the three different @entity173 .
