Abstract:
Objective To compare the epidemiological characteristics of glenoid fractures between the east and west areas in China from 2010 through 2011.Methods The data of glenoid fractures treated between January 2010 and December 2011 at 35 east hospitals and 28 west ones in China were analyzed retrospectively.The patients' gender,age and type of Ideberg classification were documented.The data from the 35 east hospitals were classified as group A while those from the 28 west ones as group B.Comparisons were made to find out the general epidemiological characteristics.Results A total of 347 glenoid fractures were collected.The total male/female ratio was 2.69∶ 1.The glenoid fractures predominated in 2 age ranges from 41 to 50 years and from 51 to 60 years (19.60％).According to the Ideberg classification,there were 75 cases (21.61％) of type Ⅰ,152 ones (43.80％) of type Ⅱ,27 ones (7.78％) of type Ⅲ,20 ones (5.76％) of type Ⅳ,46 ones (13.26％) of type Ⅴ and 27 ones (7.78％) of type Ⅵ.The male/female ratio was 2.80∶1 in group A of 228 patients and 2.50∶1 in group B of 119 patients.The median age of group A was 47 years old and that of group B 44 years old.The differences were not statistically significant in male/female ratio,median age or distribution of age between the 2 groups (P ＞ 0.05).The fractures predominated in the age range from 51 to 60 years old (23.68％) in group A and in the age range from 31 to 40 years old (21.85％) in group B.The most frequent fracture type was type Ⅱin both groups,accounting for 41.23％ and 48.74％ respectively.There was a significant difference between the 2 groups in distribution of Ideberg classification (P ＜ 0.05).Conclusions The peak age of glenoid fractures was from 41 to 60 years,the high-risk type was Ideberg type Ⅱ and there were more male patients than female ones.The proportion of Ideberg type Ⅴ in the east area was higher than that in the west area.
