Abstract

Background: Evidence for the efficacy of surgical stabilization of rib fractures in patients with rib fractures is controversial. Objective: We aim to compare the clinical outcomes of surgical rib fixation for rib fracture with non-operative treatment. Methods: Our institutional database from three general hospitals (Viet Duc Hospital, Viet Tiep Friendship Hospital & Cho Ray Hospital) was queried to identify patients with flail chest treated with locked plate fixation between December 2021 and February 2023. A medical record review for demographic, injury, hospital, and surgical data was also retrospectively performed for all patients. Characteristics and outcomes of the patients receiving the surgical rib fixation for rib fracture were compared with those without surgery. Results: A total of 166 patients with thoracic trauma were included. The majority of patients were male, and the age range was from 18 to 80 years old, with a mean age of 51.6 years. 52 (31.3%) underwent surgical stabilization of rib fractures (SSRF). The highest combined injuries were limb injuries, followed by traumatic brain injury, and maxillofacial trauma. While 1 patient died in the non-surgical group, there was no significant difference in the mortality between the two groups. The surgical group had a slightly shorter hospital stay than the non-surgical group (8.6 days vs. 10.0 days, p-value: 0.038). SSRF group tended toward a lower incidence of pneumonia compared to the non-surgical group (SSRF: 3.8% vs. non-surgical: 7%), but this difference was not statistically significant (p-value: 0.426). SSRF group also had a lower incidence of tracheostomy than the non-operative group (SSRF: 0% vs. non-surgical: 1.8%, p-value: 0.337). Conclusion: Operative fixation of a rib fracture in trauma patients resulted in a lower incidence of pneumonia, fewer days of mechanical ventilation, and a shorter hospital stay compared to non-operative treatment group.

Key words: Rib fracture, surgical stabilization of rib fractures, SSRF, rib fixation.
