Factors Associated With Surgical Treatment of Isolated, Displaced Midshaft Clavicle Fractures.

Abstract

Given the current available evidence, surgical treatment of isolated, displaced midshaft clavicle fractures is discretionary. The aim of this study was to determine whether there are identifiable factors associated with the surgical treatment of isolated, displaced midshaft clavicle fractures. A retrospective cohort study of 150 patients who underwent nonoperative treatment and 290 patients who underwent surgical treatment of isolated, displaced midshaft clavicle fractures from January 2010 to March 2019 at 2 level I trauma centers was performed. Multivariable regression analysis demonstrated that younger age (odds ratio [OR], 0.97; 95% CI, 0.95-0.99), absence of diabetes mellitus (OR, 0.045; 95% CI, 0.003-0.79), nonsmoking status (OR, 0.31; 95% CI, 0.13-0.75), higher American Society of Anesthesiologists classification (OR, 5.0; 95% CI, 2.7-9.2), fracture comminution (OR, 2.3; 95% CI, 1.3-3.9), and fracture displacement (OR, 1.1; 95% CI, 1.0-1.1) were associated with surgical treatment of an isolated, displaced midshaft clavicle fracture. Furthermore, lower social deprivation (OR, 0.99; 95% CI, 0.97-0.99) and private insurance compared with Medicare (OR, 6.6; 95% CI, 1.6-27) were associated with surgical treatment. The authors conclude that surgical treatment of discretionary midshaft clavicle fractures is influenced by patient factors, fracture characteristics, and socioeconomic factors. Further study is needed to understand the etiology of social disparities in clavicle surgery and rectify unintended trends in treatment. [Orthopedics. 2021;44(4):e515-e520.].
