Abstract:
Objective To analyze and compare epidemiological characteristics of adult single metatarsal fractures between the east and west areas in China from 2010 through 2011.Methods Thirty-five hospitals in the east area (group A) and 28 hospitals in the west area (group B) participated in this epidemiological investigation of adult single metatarsal fractures treated from January 2010 through December 2011.Data concerning gender,age and fracture location and type were documented and compared between groups A and group B.Results There were 4,779 fractures in group A and 1,708 in group B,accounting for 21.28％ (4,779/22,455) and 26.88％ (1,708/6,354) of the adult foot fractures,and 2.48％ (4,779/192,991) and 2.10％ (1,708/81,143) of all the adult fractures,respectively,showing significant differences between the 2 groups (P ＜ 0.05).The ratio of male to female was 1.21:1 in group A and 1.48:1 in group B,showing a significant difference (x2 =11.768,P =0.001).The median age of group A (43 years) was significantly older than that of group B (40 years) (Z =-6.275,P ＜ 0.001).The proportions of the patients aged from 21 to 30 years (19.02％) and of those aged from 31 to 40 years (18.62％) in group A were significantly lower than those in group B (22.66％ and 21.60％),but the proportion of the patients aged from 51 to 60 years in group A (21.09％) was significantly higher than that in group B (14.64 ％) (P ＜ 0.05).The proportions of type 87-A (40.18％) and type 87-C (5.52％) in group A were significantly lower than those in group B (44.38％ and 8.20％),but the proportion of type 87-B in group A (54.30％) was significantly higher than that in group B (47.42％) (P ＜ 0.05).There was no significant difference between the 2 groups in the distribution of fracture locations (P ＞ 0.05).Conclusions The most common single metatarsal fracture was that of the fifth metatarsal bone and the fractures of proximal metatarsal bone accounted for the largest proportion in both the cast and west areas.The west area had higher proportions of male patients and single metatarsal fracture than the east area.
