Epidemiological survey of scapular neck fractures between the east and west areas in China from 2010 through 2011 / 中华创伤骨科杂志

ABSTRACT

Objective To compare the epidemiological characteristics of scapular neck fracture between the east and west areas in China from 2010 through 2011.Methods Tbe data of scapular neck fractures treated between January 2010 and December 2011 at 35 east hospitals and 28 west ones were analyzed retrospectively.The patients' gender,age and Miller classification were documented.The data from the 35 east hospitals were classified as group A while the data from the 28 west ones as group B.Comparisons were made to find out the general epidemiological characteristics.Results A total of 584 scapular neck fractures were collected.The total male/female ratio was 3.46∶ 1.The scapular neck fractures predominated in an age range from 41 to 50 years (25.17％).According to the Miller classification,there were 150 cases (25.68％) of type Ⅰ,306 ones (52.40％) of type Ⅱ and 128 ones (21.92％) of type Ⅲ.426 cases (72.95％) were stable fractures and 158 ones (27.05％) unstable fractures.The male/female ratio was 3.64∶1 in group A of 427 patients and 3.03∶1 in group B of 157 patients.There were no significant differences between the 2 groups in male/female ratio (P ＞ 0.05).The median age of group A (44 years) was significantly older than that of group B (39 years).The fractures predominated in an age range from 41 to 50 years (24.36％) in group A and in the age range from 31 to 40 years (36.31％) in group B.The most frequent fracture type was type Ⅱ in both groups,accounting for 51.52％ and 54.78％ respectively.There were no significant differences between the 2 groups in distribution of Miller classification (P ＞ 0.05).Conclusions The peak age of scapular neck fractures was from 41 to 50 years,the high-risk type was Miller type Ⅱ and stable fractures were more common.There were more male patients than female ones.The median age in the east area was older than that in the west area.
