The Epidemiology of Radial Head and Neck Fractures

Purpose The aim of this study was to define the epidemiological characteristics of proximal radial fractures. Methods Using a prospective trauma database of 6,872 patients, we identified all patients who sustained a fracture of the radial head or neck over a 1-year period. Age, sex, socioeconomic status, mechanism of injury, fracture classification, and associated injuries were recorded and analyzed. Results We identified 285 radial head (n = 199) and neck (n = 86) fractures, with a patient median age of 43 years (range, 13–94 y). The mean age of male patients was younger when compared to female patients for radial head and neck fractures, with no gender predominance seen. Gender did influence the mechanism of injury, with female patients commonly sustaining their fracture following a low-energy fall. Radial head fractures were associated more commonly with complex injuries according to the Mason classification, while associated injuries were related to age, the mechanism of injury, and increasing fracture complexity. Conclusions Radial head and neck fractures have distinct epidemiological characteristics, and consideration for osteoporosis in a subset of patients is recommended. Type of study/level of evidence Prognostic IV.
