To analyse the trend of changes in clinical features of clavicle fractures in Third Hospital of Hebei Medical University during past 10 years.

Collect general data and imaging data of inpatients with clavicle fractures in the Third Hospital of Hebei Medical University from January 1, 2010 to December 31, 2019 for retrospective classification. All patients were divided into the first 5 years group (group A) and the last 5 years group (group B) according to the year of admission. The general data of the two groups of patients were compared and the Epidemiological trends of clavicle fractures during the 10 years were summarized.

A total of 2, 188 patients with clavicle fractures were enrolled in this study, accounting for 2.46% (2, 188/88, 886) of systemic fractures, and the ratio of male to female was 2.05:1.1 The high incidence of clavicle fractures is 41-50 years old, among which males are 65-69 years old and females are 60-64 years old. The ratio of men to women in group A is 2.23:1; group B is 1.96:1. There was no statistically significant difference in gender composition ratio between the two groups. In Group A, male aged 41-50 accounted for the highest proportion, 23.2% (124/534), and female aged 51-60 accounted for the highest proportion, 15.8% (38/240). In group B, men aged 41-50 accounted for the highest proportion, 19.9% (186/936), and women aged 61-70 accounted for the highest proportion, 17.8% (85/478). In the two groups, there was a statistically significant difference in the sex ratio between the ages of 71-80 and older than 80 years (t=5.449, P<0.05), and the difference in the sex ratio of the other age groups was not statistically significant. Falling and indoor activity injuries accounted for the highest proportion of injuries (57.9%, 1, 266/2, 188), followed by traffic accidents (28.2%, 617/2, 188). There was a statistically significant difference in the composition ratio of the causes of injury between the two groups (χ²=194.38, P<0.001). The most frequent fracture types are Allman IB and IA. Group A has the highest proportion of type IB fractures (56.7%, 439/774), followed by type ⅡB (17.1%, 132/774); group B has the highest proportion of type IB fractures (59.4%, 840/1, 414), followed by type ⅡA (15.9%, 225/1, 414). The difference in the composition ratio of fracture types between the two groups was statistically significant (χ²=87.308, P<0.001). There were 1, 798 patients undergoing surgery, 628 patients in group A and 1, 170 patients in group B. The hospital stay of the patients was (10.98±6.01) days and (10.48±4.86) days, respectively. There was a statistically significant difference in the length of hospital stay between the two groups of surgical patients (t=1.917, P<0.05).

Clavicle fractures accounted for 2.46% of total body fractures in 10 years. Compared with the previous 5 years, the proportion of clavicle fractures in total body fractures increased in the latter five years. The changing trend of clinical characteristics is that men are more than women, falling and indoor activity injuries are the most common causes of injuries. All man type I has a high incidence, but the proportion of type ⅡA fractures has increased, and the number of hospital stays has a downward trend.
