Surgical Stabilization of Rib Fractures: Relative Importance of Risk Factors for Complications

Background Surgical stabilization of rib fractures (SSRF) remains controversial as studies search for the patient population who would benefit most from SSRF. This study aimed to identify the predictive risk factors in patients with chest wall injuries who underwent SSRF and sustained in-hospital complications. Methods This study is a retrospective review of the 2016-2019 Trauma Quality Improvement Program database. Data included age, sex, comorbidities, Abbreviated Injury Score (AIS), injury pattern, interventions, and complications. All adult patients who suffered ≥1 rib fracture following an isolated thoracic injury (AIS ≥2 but < 6 and AIS ≤ 1 in all other regions) and underwent SSRF were eligible for inclusion. Results A total of 1823 patients were included in this study of whom 4.8% ( N = 87) of patients suffered an in-hospital complication. Patients who suffered a complication were generally older, male, had a higher cardiac risk, were more severely injured, and tended to have a longer time to SSRF (3.8 vs 2.5 days, P < 0.001). The top 5 predictors of in-hospital complications were RCRI, thorax AIS, time to SSRF, age, and sex. These variables were sufficient for achieving an acceptable discriminative ability for complications (AUC (95% CI): 0.78 (0.73-0.83)). Discussion Cardiovascular risk, thoracic injury severity, and delayed SSRF were correlated with elevated risk of complications. As time to surgery constitutes the sole changeable factor, prompt intervention may substantially diminish postoperative morbidity. These findings can enhance risk classification and assist therapeutic decision making for SSRF.
