Abstract
Surgical stabilization of rib fractures (SSRF) has garnered increased attention recently for treatment of blunt chest trauma (BCT). This study evaluated temporal trends in rates and timing of SSRF in isolated BCT patients, hypothesizing increased rates of early SSRF and SSRF overall. The 2017-2023 Trauma Quality Improvement Program (TQIP) database was queried for patients with ≥2 rib fractures and abbreviated injury scale <2 in non-chest regions to delineate an isolated BCT cohort. Patients were stratified by timing of SSRF from arrival: early (≤72 h), intermediate (>72-≤ 120 h), and late (>120 h). The primary outcome was annual rate of SSRF. Of 371,193 isolated BCT patients, 17 966 (4.8%) underwent SSRF from 2017 to 2023. The median age of patients undergoing SSRF increased from 58 years in 2017 to 61 years in 2023 (P < 0.001). There was an increased rate of SSRF performed from 2017 to 2023 (n = 1,594, 3.5% vs n = 3,435, 5.5%, P < 0.001). When stratified by timing, early (1.8% [2017]; 3.4% [2023], P < 0.001) and intermediate SSRF (0.9% [2017]; 1.3% [2023], P < 0.001) increased over time, whereas late SSRF remained similar across 2017 to 2023 (late: 0.8%; 0.8%, P = 0.25). For all SSRF patients, median overall length of stay (LOS) decreased over time (12 [IQR: 8-17] days [2017]; 11 [IQR: 8-16] days [2023]; P < 0.001). This study demonstrates a nearly 60% relative national increase in SSRF from 2017 to 2023, with a progressively older patient cohort and shorter LOS. This was predominantly attributable to increased early (≤72 h) and intermediate (>72-≤120 h) SSRF cases, aligning with existing guidelines.
Introduction
Rib fractures are a common consequence of blunt thoracic trauma, with some studies reporting fractures in 10% of all trauma patients 1 and up to 55% of patients who experienced specifically blunt chest trauma.2,3 Mortality associated with rib fractures ranges from 6% to 12% and increases with a greater number of fractures.2,3 Among patients older than 65 years, rib fractures are associated with a 2-fold higher risk of mortality compared to younger adults.4,5
Historically, the management of rib fractures has been predominantly nonoperative, emphasizing analgesia, pulmonary hygiene, and supportive care. 6 Though there have been several surgical approaches to rib fixation dating back to over a century ago, 7 widespread adoption did not occur until more recent randomized trials demonstrated benefits for patients who failed to liberate from mechanical ventilation, as well as patients with flail chest and those with significant non-flail patterns of rib fractures.8–10 These data supported more routine use of surgical stabilization of rib fractures (SSRF)8,10 in contemporary trauma practice, leading to the formation of the Chest Wall Injury Society (CWIS) and the publication of national guidelines.11,12
In addition to patient selection, the timing of SSRF has become an important area of investigation. Multiple studies have demonstrated improved outcomes when SSRF is performed within 72
Therefore, this study aimed to evaluate how the timing and rates of SSRF have changed in recent years (2017-2023) for isolated blunt chest trauma patients and whether this has impacted outcomes including LOS. We hypothesized there would be an increase in the overall rate of SSRF over this time period, with a specific increase in early SSRF (≤72 h from arrival) in 2023 compared to the pre-guideline period of 2017.
Methods
The 2017-2023 TQIP database was queried for all patients 18 years of age and older presenting with ≥2 rib fractures. Patients with an abbreviated injury scale (AIS) grade <2 in non-chest regions (head, face, spine, and abdomen) were included to delineate a near-isolated blunt chest trauma cohort, excluding patients with AIS ≥2 injuries in these regions, as concomitant injuries may delay or preclude SSRF. This was done using International Classification of Disease, 10th Revision codes (ICD-10) which are included in a separate appendix. We did not incorporate AIS thorax into our analysis for the following reasons: first, we excluded patients by number of rib fractures and second, AIS thorax was clinically similar (albeit statistically different) across the study period with a median of 3 (interquartile range 3-3) in each year.
The primary outcome was the annual rate of SSRF from 2017 to 2023. Patients were stratified by and compared across years. Additional planned analyses were performed where patients were stratified by timing of SSRF and compared across years from 2017 to 2023. Early SSRF was defined as ≤72 h from hospital arrival, intermediate SSRF as >72 to ≤120 h from arrival, and late SSRF as >120 h from arrival. Additional variables evaluated included the median age of patients and median total hospital LOS across the study period. Some patients were missing data for LOS and timing of operation and were excluded for those respective analyses.
Bivariate analyses were performed using chi-square tests to compare categorical variables. Continuous variables were compared across years using the Kruskal-Wallis test, given non-normal distributions and reporting of medians with interquartile range. Chi-square analysis was also used to assess variation over time. Logistic regression analysis using year as a predictor was additionally performed to assess trends over time for SSRF rates. Categorical data were reported as percentages, and continuous data were reported as medians with interquartile range (IQR). SSRF rates were calculated percentages of the total isolated blunt chest trauma cohort and of the proportion of all SSRF patients each year. All P-values were two-sided, with a statistical significance level of <0.05. All statistical analyses were performed using IBM SPSS Statistics for Windows (Version 31, IBM Corp., Armonk, NY). This study was deemed exempt by our institutional review board as it utilizes a national deidentified database.

Discussion
Rib fractures remain a frequent and morbid injury following blunt chest trauma, and SSRF has become an increasingly utilized operative strategy for select patients. In this national analysis of isolated blunt chest trauma patients, we found a nearly 60% relative increase in SSRF utilization from 2017 to 2023, driven largely by growth in early and intermediate fixation, alongside a progressively older operative cohort and a modest reduction in hospital LOS. When evaluating SSRF within each year, the proportion of early SSRF increased, whereas the proportion of late SSRF decreased. Overall, these findings suggest evolving national practice patterns that parallel published evidence and guideline recommendations regarding both patient selection and timing of SSRF.
At times, surgical procedures may have increased research but not receive widespread adoption due to cost, technical challenges, and/or other potential barriers. 15 Prior to 2017, one study using the National Trauma Database (NTDB) demonstrated an over 35% increase in SSRF utilization from 2007 to 2014, with the overall rate of SSRF performed during the study period being 4.3%. 16 Our more contemporary analysis following the publication of recent guidelines in 2017 12 found a more than 50% increase in the national rate of SSRF for near-isolated blunt chest trauma during the study period. This is similar to findings by Zangbar et al across 2017-2021. 17 This is likely due to a combination of factors including increased research on the short and long-term benefits of SSRF,16,18 as well as the improved fidelity of existing hardware and increased opportunities for education led by industry as well as societies such as CWIS. 7 Additionally, there are multiple studies now demonstrating safety and benefit of SSRF in older adults,6,19 which likely led to the increasing age of the cohort in our study as well other reports.19,20
With increasing adoption of SSRF, there has also been increased discussion regarding the optimal timing of SSRF. Several studies, including but not limited to the Eastern Association for the Surgery of Trauma (EAST) and CWIS guidelines, recommend performing SSRF as early as possible, with CWIS recommending within 3 days of arrival.11–14 While a 2018 multicenter prospective study found an increase in both overall SSRF cases and early SSRF (<24
While much of the current evidence shows that patients undergoing SSRF have a shorter overall and/or intensive care unit LOS when compared with patients undergoing nonoperative management,8,10,12,21 some research has shown equivalent or longer LOS with SSRF.

This study is limited by multiple factors inherent to large national database studies, namely, a risk of misclassification as well as selection and reporting bias. Additionally, our results do not capture the full extent of SSRF cases performed nationally, as we excluded the majority of polytrauma patients who underwent SSRF (eg, AIS ≥2 in non-chest regions). The TQIP also only includes patients with a minimum Injury Severity Score of 9. Therefore, the results may not be generalizable to all blunt trauma patients. In addition, our study lacks granular details related to the injury profiles (ie, Rib Score and flail vs non-flail), indications for the SSRF, and other pertinent factors including pain scores, analgesia and adjuncts including epidural catheters, peripheral blocks, and nerve cryoablation18,24 surgeon experience, and type of SSRF system used. Though there is significant variation of the median LOS over time, there is an inflection point earlier in the study period than 2023. Our statistical analysis did not take into account hospital variations, AIS thorax scores, comorbid conditions, or mechanisms of injury which may affect decisions related to SSRF. Lastly, our study did not exclude patients with AIS ≥2 in upper or lower extremities, which can include some pelvic fractures. The omission of these variables could potentially lead to bias due to delays in operative timing. Despite these limitations, this study is strengthened by its large power and inclusion of centers across the country thus providing increased generalizability of its findings.
Conclusions
This national analysis spanning 7 years of data demonstrates a nearly 60% relative national increase in SSRF from 2017 to 2023, with a progressively older cohort of near-isolated blunt trauma patients undergoing SSRF. This increase was primarily driven by greater use of early and intermediate fixation, while rates of late SSRF remained unchanged. In parallel, a progressively older patient population underwent SSRF, and a small reduction in overall hospital LOS was observed over time. Together, these findings suggest increasing national alignment with contemporary evidence and guideline recommendations favoring earlier SSRF.
