Surgical Rib Fixation is Associated With Lower Mortality in Patients With Traumatic Rib Fractures

INTRODUCTION

Nonoperative management (NOM) along with supportive care has been the adopted approach for traumatic rib fractures; however, surgical approaches have emerged recently to treat this common pathology. Despite this, there are no guidelines for surgical rib fixation in patients with traumatic rib fractures.

METHODS

An institutional review board-approved retrospective cohort study was performed at the Puerto Rico Trauma Hospital aiming to compare the outcomes and complications between patients with traumatic rib fractures who undergo surgical fixation and their counterparts with NOM. The study period comprised from January 2016 through July 2020. Outcomes were evaluated with negative binomial and logistic regressions.

RESULTS

Fifty patients were identified for the surgical rib fixation group, who were matched to 150 patients who received NOM. The majority of patients were male (91.5%), with a median (interquartile range) age of 53 (29) years. Concomitant chest injuries were significantly more prevalent in the operative group, such as flail segment (P < 0.001), number of fractures (P < 0.001), and displaced rib fractures (P < 0.001). Although hospital length of stay was 25% (95% confidence interval: 1.02-1.54) longer in the surgical group, this intervention was associated with an 85% (95% confidence interval: 0.03-0.70) lower mortality rate when compared to conservative management.

CONCLUSIONS

Rib fixation may offer some benefits in selected patients with traumatic rib fractures, such as those with bilateral rib fractures, multiple displaced rib fractures, flail segment, and concomitant thoracic injuries. This study may serve as a guide for treatment strategy and patient selection regarding the surgical management of traumatic rib fractures.

Long term outcomes following rib fracture fixation in patients with major chest trauma

BACKGROUND

Severe chest injuries are associated with significant morbidity and mortality. Surgical rib fixation has become a more commonplace procedure to improve chest wall mechanics, pain, and function. The aim of this study was to characterise the epidemiology and long-term functional outcomes of chest trauma patients who underwent rib fixation in a major trauma centre (MTC).

METHODOLOGY

This was a retrospective review (2014-19) of all adult patients with significant chest injury who had rib fixation surgery following blunt trauma to the chest. The primary outcome was functional recovery after hospital discharge, and secondary outcomes included length of intensive care unit (ICU) and hospital stay, maximum organ support, tracheostomy insertion, ventilator days.

RESULTS

60 patients underwent rib fixation. Patients were mainly male (82%) with median age 52 (range 24-83) years, injury severity score (ISS) of 29 (21-38), 10 (4-19) broken ribs, and flail segment in 90% of patients. Forty-six patients (77%) had a good outcome (GOSE grade 6-8). Patients in the poor outcome group (23%; GOSE 1-5) tended to be older [55 (39-83) years vs. 51 (24-78); p = 0.05] and had longer length of hospital stay [42 (19-82) days vs. 24 (7-90); p<0.01]. Injury severity, rate of mechanical ventilation or organ dysfunction did not affect long term outcome. Nineteen patients (32%) were not mechanically ventilated.

CONCLUSIONS

Rib fixation was associated with good long-term outcomes in severely injured patients. Age was the only predictor of long-term outcome. The results suggest that rib fixation be considered in patients with severe chest injuries and may also benefit those who are not mechanically ventilated but are at risk of deterioration.
