The yield of subsequent radiographs during nonoperative treatment of radial head and neck fractures

Abstract

Objectives: After diagnosis of an isolated radial head or neck fracture and selection of nonoperative treatment, the value of subsequent radiographs is uncertain. This study tested the null hypothesis that there are no patient, surgeon, or injury factors associated with alteration in patient management based on subsequent radiographs. Secondarily, we tested the null hypothesis that the use of subsequent radiographs is not associated with patient, surgeon, and fracture characteristics.

Methods: We identified 415 adult patients with nonoperative treatment for isolated Broberg and Morrey modified Mason type 1 or 2 fractures at a large urban hospital system during years 2013 and 2014. Patient demographics, fracture characteristics, provider characteristics, and treatment details were obtained from a hospital database. Bivariate analysis and multivariable logistic regression modeling were performed.

Results: One of 255 patients with 262 fractures that had subsequent radiographs (0.4%) was offered surgery but declined. In multivariable analysis, displaced fractures were more likely to have subsequent radiographs, but surgeon-to-surgeon variation was a far more influential factor.

Conclusions: Radiographs subsequent to diagnosis do not alter treatment of radial head fractures with no associated ligament injuries or fractures. The substantial surgeon-to-surgeon variation in the use of subsequent radiographs suggests that this may be a good focus for quality improvement initiatives.
