RESUMO
Objective To analyze the epidemiological features and trends of glenoid fractures from 2003 through 2012 in the Third Affiliated Hospital to Hebei Medical University.Methods The clinical data were collected of the patients with glenoid fracture who had been treated between January 2003 and December 2012 in our hospital.The patients' gender,age and fracture type of Ideberg classification were documented.The data from January 2003 to December 2007 were assigned into group A and those from January 2008 to December 2012 into group B.The 2 groups were compared to find out the general epidemiological characteristics and trends in the recent 10 years.Results A total of 225 patients with glenoid fracture were collected,including 176 males and 49 females.The total male/female ratio was 3.59∶ 1.The glenoid fractures predominated in an age range of 31 to 40 years (23.56％).According to Ideberg classification,there were 35 cases (15.56％) of type Ⅰ,58 ones (25.78％) of type Ⅱ,64 ones (28.44％) of type Ⅲ,21 ones (9.33％) of type Ⅳ,30 ones(13.33％) of type Ⅴ and 17 ones(7.56％) of type Ⅵ.The male/female ratio was 5.29∶1 in group A of 107 patients and 2.69∶1 in group B of 118 patients.The mean age of group A was 40.2 ± 16.0 years and that of group B 47.5 ± 14.8 years.The differences in male/female ratio,mean age and distribution of age were statistically significant between the 2 groups (P ＜ O.05).The fractures predominated in an age range of 31 to 40 years (28.97％) in group A and in the age group of 51 to 60 years (27.12％) in group B.The most frequent fracture type was type Ⅲ in both groups,accounting for 29.91％ and 27.12％ respectively.There was no significant difference between the 2 groups in distribution of Ideberg classification (P ＞ 0.05).Conclusions The peak age of glenoid fractures was from 31 to 40 years.There was an increasing trend in the mean age.There were more male patients than female ones.The high-frequency type was Ideberg type Ⅲ.
