Abstract
A number of studies have described the epidemiological characteristics of clavicle fractures, including two previous reports from our institution. The Robinson classification system was described in 1998, after the analysis of 1,000 clavicle fractures. We aim to provide a contemporary analysis and compare current clavicle fracture patterns of our adult population with historical reports.
A retrospective analysis of a prospectively collected fracture database from an institution serving 598,000 was conducted. Demographic data were recorded prospectively for each patient with an acute clavicle fractures including age, gender, mode of injury, fracture classification, and the presence of associated skeletal injuries. Fractures were classified according to the Robinson system.
A total of 312 clavicle fractures were identified, occurring with an incidence of 55.9/100,000/yr (CI 49.8–62.5) and following a bimodal male and unimodal older female distribution. Sporting activity and a simple fall from standing caused the majority of injuries. More than half of simple fall fractures affected the lateral clavicle. The incidence of clavicle fractures has risen over a twenty year period, and a greater proportion of older adults are now affected. Overall, type II midshaft fractures remain the most common, but comparison of this series with historical data reveals that the epidemiology of clavicle fractures is changing.
We have identified an increase in the average patient age and overall incidence of clavicle fractures in our adult population. The incidence, relative frequency, and average patient age of type III lateral one-fifth fractures have increased. This epidemiological trend has implications for the future management of clavicle fractures in our region.
