Epidemiological comparison of adult talus fractures between East China and West China from 2010 to 2011

Abstract

Objective To compare and analyze the epidemiological features of adult talus fractures between East China and West China from 2010 to 2011. Methods The data of adult talus fractures from January 2010 to December 2011 in 63 hospitals in East China and West China were collected through the PACS system and medical records systems. The data of 35 hospitals in East China were assigned into group A while the data of 28 hospitals in West China into group B. The analytic items included gender, age, and type of AO classification. Results A total of 1,014 cases were collected. In group A of 825 cases, there were 624 (75.64%) males and 201 (24.36%) females; in group B of 189 cases, there were 130 (68.78%) males and 59 (31.22%) females. There was no significant difference between groups A and B in male to female ratio (χ2=3.788, P=0.052). The mean age was 36 years old (26, 47) in group A and 35 (24, 48) years old in group B, showing no significant difference between the 2 groups (Z=-8.244, P< 0.001). There was a significant difference between the 2 groups in the constituent ratio of age ranges(P< 0.05). The peak age range was from 21 to 30 years old in group A (27.76%, 229/825), and from 31 to 40 years old in group B (24.34%, 46/189). The high-risk type of fracture was AO type 81-A in both groups. Conclusions There were more male talus fractures than female ones in both East China and West China. Most talus fractures happened in patients aged from 21 to 30 years in East China and in patients aged from 31 to 40 years in West China. AO Type 81-A was the most common in both West and East China.
