Epidemiological survey of supracondylar humeral fractures from 2003 to 2012 at The Third Affiliated Hospital to Hebei Medical University / 中华创伤骨科杂志

ABSTRACT

Objective To investigate the epidemiological features and trends of supracondylar humeral fractures from 2003 to 2012 at The Third Affiliated Hospital to Hebei Medical University.Methods The data of the patients with supracondylar humeral fracture who had been treated between 2003 and 2012 at our hospital were collected through the PACS system and case reports checking system.The data between 2003 and 2007 were classified as group A and those between 2008 and 2012 as group B.The data concerning gender,age and fracture type were statistically analyzed and compared between the 2 groups.Results Atotalof3,111 supracondylar humeral fractures were treated,accounting for54.4％ (3,111/5,723) of the distal humeral fractures,34.8％ (3,111/8,932) of the elbow fractures and 2.5％ (3,111/126,479) of the total fractures.They were 2,018 males (64.9％) and 1,093 females (35.1％).The age range from 1 to 10 years obtained the highest constitute ratio for both genders,77.0％ (1,554/2,018) for males and 78.2％ (854/1,093) for females.The extension type and flexion type had 2,693 (86.6％) and 418 (13.4％) cases,respectively,and their male to female ratios were 2.01 and 1.21 respectively,all showing significant differences (P ＜ 0.001).There were 1,902 cases in group A and 1,209 cases in group B,accounting for 60.0％ (1,902/3,168) and 47.3％ (1,209/2,555) of the distal humeral fractures,41.4％ (1,902/4,199) and 27.9％ (1,209/4,333) of the elbow fractures,and 2.9％ (1,902/65,267) and 2.0％ (1,209/61,212) of the total fractures,respectively,all showing significant differences between groups (P ＜ 0.001).The male to female ratio was 1.91 for group A and 1.81 for group B,showing an insignificant difference (P ＞ 0.05).The age range from 1 to 10 years had a constitute ratio of 75.0％ (1,426/1,902) for group A and that of 81.2％ (982/1,209) for group B,showing a significant difference (P ＜ 0.001).The proportion of extension type was 85.4％ (1,624/1,902) for group A and 88.4％ (1,069/1,209) for group B,showing a significant difference (P ＜ 0.05).Conclusions The current investigation has revealed the epidemiological features and trends of supracondylar humeral fractures which had been treated between 2003 and 2012.They were mostly seen in children from 1 to 10 years old.The extension type predominated.Compared with the first 5 years,the proportion of age range from 1 to 10 years and the extension type increased in the latter 5 years.
