BACKGROUND Prospective studies of surgical stabilization of rib fractures (SSRF) have excluded elderly patients, and no study has exclusively addressed the ≥80-year-old subgroup. We hypothesized that SSRF is associated with decreased mortality in trauma patients 80 years or older. METHODS Multicenter retrospective cohort study involving eight centers. Patients who underwent SSRF from 2015 to 2020 were matched to controls by study center, age, injury severity score, and presence of intracranial hemorrhage. Patients with chest Abbreviated Injury Scale score less than 3, head Abbreviated Injury Scale score greater than 2, death within 24 hours, and desire for no escalation of care were excluded. A subgroup analysis compared early (0-2 days postinjury) to late (3-7 days postinjury) SSRF. Poisson regression accounting for clustered data by center calculated the relative risk (RR) of the primary outcome of mortality for SSRF versus nonoperative management. RESULTS Of 360 patients, 133 (36.9%) underwent SSRF. Compared with nonoperative patients, SSRF patients were more severely injured and more likely to receive locoregional analgesia. There were 31 hospital deaths among the entire sample (8.6%). Multivariable regression demonstrated a decreased risk of mortality for the SSRF group, as compared with the nonoperative group (RR, 0.41; 95% confidence interval, 0.24-0.69; p < 0.01). However, SSRF patients were more likely to develop pneumonia, and had an increased duration of both mechanical ventilation and intensive care unit stay. There were no differences in discharge destination, although the SSRF group was less likely to be discharged on narcotics (RR, 0.66; 95% confidence interval, 0.48-0.90; p = 0.01). There was no difference in adjusted mortality between the early and late SSRF subgroups. CONCLUSION Patients selected for SSRF were substantially more injured versus those managed nonoperatively. Despite this, SSRF was independently associated with decreased mortality. With careful patient selection, SSRF may be considered a viable treatment option in octogenarian/nonagenarians. LEVEL OF EVIDENCE Therapeutic, Level IV.

BACKGROUND: Outcomes after surgical stabilization of rib fractures (SSRF) have not been studied in patients with multiple rib fractures and traumatic brain injury (TBI). We hypothesized that SSRF, as compared with nonoperative management, is associated with favorable outcomes in patients with TBI. METHODS: A multicenter, retrospective cohort study was performed in patients with rib fractures and TBI between January 2012 and July 2019. Patients who underwent SSRF were compared to those managed nonoperatively. The primary outcome was mechanical ventilation-free days. Secondary outcomes were intensive care unit length of stay and hospital length of stay, tracheostomy, occurrence of complications, neurologic outcome, and mortality. Patients were further stratified into moderate (GCS score, 9-12) and severe (GCS score, ≤8) TBI. RESULTS: The study cohort consisted of 456 patients of which 111 (24.3%) underwent SSRF. The SSRF was performed at a median of 3 days, and SSRF-related complication rate was 3.6%. In multivariable analyses, there was no difference in mechanical ventilation-free days between the SSRF and nonoperative groups. The odds of developing pneumonia (odds ratio [OR], 0.59; 95% confidence interval [95% CI], 0.38-0.98; p = 0.043) and 30-day mortality (OR, 0.32; 95% CI, 0.11-0.91; p = 0.032) were significantly lower in the SSRF group. Patients with moderate TBI had similar outcome in both groups. In patients with severe TBI, the odds of 30-day mortality was significantly lower after SSRF (OR, 0.19; 95% CI, 0.04-0.88; p = 0.034). CONCLUSION: In patients with multiple rib fractures and TBI, the mechanical ventilation-free days did not differ between the two treatment groups. In addition, SSRF was associated with a significantly lower risk of pneumonia and 30-day mortality. In patients with moderate TBI, outcome was similar. In patients with severe TBI a lower 30-day mortality was observed. There was a low SSRF-related complication risk. These data suggest a potential role for SSRF in select patients with TBI. LEVEL OF EVIDENCE: Therapeutic, level IV.

BACKGROUND The efficacy of surgical stabilization of rib fracture (SSRF) in patients without flail chest has not been studied specifically. We hypothesized that SSRF improves outcomes among patients with displaced rib fractures in the absence of flail chest. METHODS Multicenter, prospective, controlled, clinical trial (12 centers) comparing SSRF within 72 hours to medical management. Inclusion criteria were three or more ipsilateral, severely displaced rib fractures without flail chest. The trial involved both randomized and observational arms at patient discretion. The primary outcome was the numeric pain score (NPS) at 2-week follow-up. Narcotic consumption, spirometry, pulmonary function tests, pleural space complications (tube thoracostomy or surgery for retained hemothorax or empyema >24 hours from admission) and both overall and respiratory disability-related quality of life (RD-QoL) were also compared. RESULTS One hundred ten subjects were enrolled. There were no significant differences between subjects who selected randomization (n = 23) versus observation (n = 87); these groups were combined for all analyses. Of the 110 subjects, 51 (46.4%) underwent SSRF. There were no significant baseline differences between the operative and nonoperative groups. At 2-week follow-up, the NPS was significantly lower in the operative, as compared with the nonoperative group (2.9 vs. 4.5, p < 0.01), and RD-QoL was significantly improved (disability score, 21 vs. 25, p = 0.03). Narcotic consumption also trended toward being lower in the operative, as compared with the nonoperative group (0.5 vs. 1.2 narcotic equivalents, p = 0.05). During the index admission, pleural space complications were significantly lower in the operative, as compared with the nonoperative group (0% vs. 10.2%, p = 0.02). CONCLUSION In this clinical trial, SSRF performed within 72 hours improved the primary outcome of NPS at 2-week follow-up among patients with three or more displaced fractures in the absence of flail chest. These data support the role of SSRF in patients without flail chest. LEVEL OF EVIDENCE Therapeutic, level II.

INTRODUCTION Locoregional analgesia (LRA) remains underused in patients with chest wall injuries. Surgical stabilization of rib fractures (SSRF) offers an opportunity to deliver surgeon-directed LRA under direct visualization at the site of surgical intervention. We hypothesized that a single-dose liposomal bupivacaine (LB) intercostal nerve block provides comparable analgesia to an indwelling, peripheral nerve plane analgesic catheter with continuous bupivacaine infusion (IC), each placed during SSRF. METHODS Noninferiority, single-center, randomized clinical trial (2017-2020) was performed. Patients were randomized to receive either IC or LB during SSRF. The IC was tunneled into the surgical field (subscapular space), and LB involved thoracoscopic intercostal blocks of ribs 3 to 8. The primary outcome was the Sequential Clinical Assessment of Respiratory Function score, measured daily for 5 days postoperatively. Secondary outcomes included daily narcotic equivalents and failure of primary LRA, defined as requiring a second LRA modality. RESULTS Thirty-four patients were enrolled: 16 IC and 18 LB. Age, Injury Severity Score, RibScore, Blunt Pulmonary Contusion Score, and use of nonnarcotic analgesics was similar between groups. Duration of IC was 4.5 days. There were three failures in the IC group versus one in the LB group (p = 0.23). There was no significant difference in Sequential Clinical Assessment of Respiratory Function score between the IC and LB groups. On postoperative days 2 to 4, narcotic requirements were less than half in the LB, as compared with the IC group; however, this difference was not statistically significant. Average wholesale price was US $605 for IC and US $434 for LB. CONCLUSION In this noninferiority trial, LB provided at least comparable and potentially superior LRA as compared with IC among patients undergoing SSRF. LEVEL OF EVIDENCE Therapeutic, level II.
