Abstract
ObjectiveTo analyze the clinical feature and constituent ratio of adult hip fractures in Southwest China.
MethodsThe 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.
ResultsThere 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: 1 226 fractures, 61.64%) in the geriatric group, with a significant difference in the sex distribution between the two groups (χ2=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.
ConclusionsWomen 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.
