Delayed flail chest from osteomyelitis and malnutrition that emerged 3 weeks after blunt chest trauma: a case report.

We present the case of a victim of a motor vehicle accident in his late 60s who suffered from severe torso injuries. He initially presented with abdominal and chest pain, and underwent emergency laparotomy for hemoperitoneum. After surgery, the patient developed pneumonia and septicemia, which were responsive to antibiotics. The patient was treated with mechanical ventilation in the intensive care unit for approximately 10 days and experienced a severe weight loss of approximately 30%, but slowly recovered without dyspnea. Notably, on hospital day 24, he experienced sudden respiratory distress and flail motion of the chest wall in a general ward. This late presentation of flail chest was attributed to non-union at rib fracture sites, and was likely exacerbated by malnutrition and osteomyelitis. Surgical stabilization of rib fractures and excision of the infected rib were successfully performed. The findings from this case highlight the complexity of managing delayed onset of flail chest. The findings from this case suggest the importance of vigilance for late emerging complications in patients with trauma, even when initial symptoms are absent.

Evolution of Pulmonary Contusions in Patients With Severe Rib Fractures: Cause for Concern?

INTRODUCTION: The progression of pulmonary contusions remains poorly understood. This study aimed to measure the radiographic change in pulmonary contusions over time and evaluate the association of the radiographic change with clinical outcomes and surgical stabilization of rib fractures (SSRF). METHODS: This retrospective cohort study included adults admitted with three or more displaced rib fractures or flail segment on trauma CT and when a chest CT was repeated within one week after trauma. Radiographic severity of pulmonary contusions was assessed using the Blunt Pulmonary Contusion Score (BPC18). Logistic regression was performed to evaluate the relation between SSRF and worsening contusions on repeat CT, adjusted for potential confounders. RESULTS: Of 231 patients, 56 (24%) had a repeat CT scan. Of these, 55 (98%) had pulmonary contusion on the first CT scan with a median BPC18 score of 5 (P25-P75 3-7). Repeat CTs showed an overall decrease of the median BPC18 score to 4 (P25-P75 2-6, P = .02), but demonstrated a worsening of the pulmonary contusion in 16 patients (29%). All repeat CTs conducted within 12 hours post-injury demonstrated increasing BPC18. Radiographic worsening of pulmonary contusions was not associated with SSRF, nor with worse respiratory outcomes or intensive care length of stay, compared to patients with radiographically stable or improving contusions. DISCUSSION: In patients with severe rib fracture patterns who undergo repeat imaging, pulmonary contusions are prevalent and become radiographically worse within at least the first 12 hours after injury. No association between radiographic worsening and clinical outcomes was found.

Impact of flail chest injury on morbidity and outcome: ten years' experience at a tertiary care hospital in a developing country.

BACKGROUND: One of the worst types of severe chest injuries seen by clinicians is flail chest. This study aims to measure the overall mortality rate among flail chest patients and then to correlate mortality with several demographic, pathologic, and management factors. METHODOLOGY: A retrospective observational study tracked a total of 376 flail chest patients admitted to the emergency intensive care unit (EICU) and surgical intensive care unit (SICU) at Zagazig University over 120 months. The main outcome measurement was overall mortality. The secondary outcomes were the association of age and sex, concomitant head injury, lung and cardiac contusions, the onset of mechanical ventilation (MV) and chest tubes insertion, the length of mechanical ventilation and ICU stay in days, injury severity score (ISS), associated surgeries, pneumonia, sepsis, the implication of standard fluid therapy and steroid therapy, and the systemic and regional analgesia, with the overall mortality rates. RESULTS: The mortality rate was 19.9% overall. The shorter onset of MV and chest tube insertion, and the longer ICU, and hospital length of stay were noted in the mortality group compared with the survived group (P-value less than 0.05). Concomitant head injuries, associated surgeries, pneumonia, pneumothorax, sepsis, lung and myocardial contusion, standard fluid therapy, and steroid therapy were significantly correlated with mortality (P-value less than 0.05). MV had no statistically significant effect on mortality. Regional analgesia (58.8%) had a significantly higher survival rate than intravenous fentanyl infusion (41.2%). In multivariate analysis, sepsis, concomitant head injury, and high ISS were independent predictors for mortality [OR (95% CI) = 568.98 (19.49-16613.52), 6.86 (2.86-16.49), and 1.19 (1.09-1.30), respectively]. CONCLUSION: The current report recorded mortality of 19.9% between flail chest injury patients. Sepsis, concomitant head injury, and higher ISS are the independent risk factors for mortality when associated with flail chest injury. Considering restricted fluid management strategy and regional analgesia may help better outcome for flail chest injury patients.

Randomized Controlled Trial of Surgical Rib Fixation to Nonoperative Management in Severe Chest Wall Injury.

OBJECTIVE: To compare the effectiveness of surgical stabilization of rib fractures (SSRFs) to nonoperative management in severe chest wall injury. BACKGROUND: SSRF has been shown to improve outcomes in patients with clinical flail chest and respiratory failure. However, the effect of SSRF outcomes in severe chest wall injuries without clinical flail chest is unknown. METHODS: Randomized controlled trial comparing SSRF to nonoperative management in severe chest wall injury, defined as: (1) a radiographic flail segment without clinical flail or (2) ≥5 consecutive rib fractures or (3) any rib fracture with bicortical displacement. Randomization was stratified by the unit of admission as a proxy for injury severity. Primary outcome was hospital length of stay (LOS). Secondary outcomes included intensive care unit (ICU) LOS, ventilator days, opioid exposure, mortality, and incidences of pneumonia and tracheostomy. Quality of life at 1, 3, and 6 months was measured using the EQ-5D-5L survey. RESULTS: Eighty-four patients were randomized in an intention-to-treat analysis (usual care = 42, SSRF = 42). Baseline characteristics were similar between groups. The numbers of total fractures, displaced fractures, and segmental fractures per patient were also similar, as were the incidences of displaced fractures and radiographic flail segments. Hospital LOS was greater in the SSRF group. ICU LOS and ventilator days were similar. After adjusting for the stratification variable, hospital LOS remained greater in the SSRF group (RR: 1.48, 95% CI: 1.17-1.88). ICU LOS (RR: 1.65, 95% CI: 0.94-2.92) and ventilator days (RR: 1.49, 95% CI: 0.61--3.69) remained similar. Subgroup analysis showed that patients with displaced fractures were more likely to have LOS outcomes similar to their usual care counterparts. At 1 month, SSRF patients had greater impairment in mobility [3 (2-3) vs 2 (1-2), P = 0.012] and self-care [2 (1-2) vs 2 (2-3), P = 0.034] dimensions of the EQ-5D-5L. CONCLUSIONS: In severe chest wall injury, even in the absence of clinical flail chest, the majority of patients still reported moderate to extreme pain and impairment of usual physical activity at one month. SSRF increased hospital LOS and did not provide any quality of life benefit for up to 6 months.

Early Surgical Stabilization of Rib Fractures is Feasible in Patients With Non-Urgent Operative Pelvic Injuries.

INTRODUCTION: The feasibility of prioritizing surgical stabilization of rib fractures (SSRF) in patients with other injuries is unknown. The purpose of this study was to evaluate the timing and outcomes of SSRF between patients with and without non-urgent operative pelvic injuries. PATIENTS AND METHODS: In this retrospective observational study, all patients between 2010 and 2020 who underwent SSRF (SSRF group) and those who underwent SSRF and non-urgent operative management of pelvic fractures (SSRF + P group) were included. Demographics, injury characteristics, operative details, and outcomes were compared between the 2 groups. RESULTS: Over 11 years, 154 SSRF patients were identified, with 143 patients in the SSRF group (93%) and 11 patients in the SSRF + P group (7%). Median number of rib fractures (7 vs 9, P = .04), total number of fractures (11 vs 15, P < .01), and flail segment (54% vs 91%, P = .02) were higher in SSRF + P group. Median time to SSRF was similar (0 vs 1 day, P = .20) between the 2 groups. Median time to pelvic fixation was 3 days in SSRF + P group and 8 out of 11 patients (73%) underwent SSRF prior to pelvic fixation. Median operative time (137 vs 178 mins, P = .14) and median number of ribs plated (4 vs 5, P = .05) were higher in SSRF + P group. There was no difference in SSRF-related complications, pelvic fracture-related complications from operative positioning, rates of pneumonia, or mortality between the 2 groups. CONCLUSIONS: SSRF can be performed early in patients with non-urgent operative pelvic injuries without a difference in pelvic fracture-related complications, SSRF-related complications, pneumonia, or mortality.

Early surgical stabilization of rib fractures for flail chest is associated with improved patient outcomes: An ACS-TQIP review.

BACKGROUND: Rib fractures are a common in thoracic trauma. Increasingly, patients with flail chest are being treated with surgical stabilization of rib fractures (SSRF). We performed a retrospective review of the Trauma Quality Improvement Program database to determine if there was a difference in outcomes between patients undergoing early SSRF (≤3 days) versus late SSRF (>3 days). METHODS: Patients with flail chest in Trauma Quality Improvement Program were identified by CPT code, assessing those who underwent SSRF between 2017 and 2019. We excluded those younger than 18 years and Abbreviated Injury Scale head severity scores greater than 3. Patients were grouped based on SSRF before and after hospital Day 3. These patients were case matched based on age, Injury Severity Score, Abbreviated Injury Scale head and chest, body mass index, Glasgow Coma Scale, and five modified frailty index. All data were examined using χ2, one-way analysis of variance, and Fisher's exact test within SPSS version 28.0. RESULTS: For 3 years, 20,324 patients were noted to have flail chest, and 3,345 (16.46%) of these patients underwent SSRF. After case matching, 209 patients were found in each group. There were no significant differences between reported major comorbidities. Patients with early SSRF had fewer unplanned intubations (6.2% vs. 12.0%; p = 0.04), fewer median ventilator days (6 days Q1: 3 to Q3: 10.5 vs. 9 Q1: 4.25 to Q3: 14; p = 0.01), shorter intensive care unit length of stay (6 days Q1: 4 to Q3: 11 vs. 11 Q1: 6 to Q3: 17; p < 0.01), and hospital length of stay (15 days Q1: 11.75 to Q3: 22.25 vs. 20 Q1: 15.25 - Q3: 27, p < 0.01. Early plating was associated with lower rates of deep vein thrombosis and ventilator-acquired pneumonia. CONCLUSION: In trauma-accredited centers, patients with flail chest who underwent early SSRF (<3 days) had better outcomes, including fewer unplanned intubations, decreased ventilator days, shorter intensive care unit LOS and HLOS, and fewer DVTs, and ventilator-associated pneumonia. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level IV.

Age as a Barrier to Surgical Stabilization of Rib Fractures in Patients with Flail Chest.

INTRODUCTION: Although randomized trials demonstrate a benefit to surgical stabilization of rib fractures (SSRF), SSRF is rarely performed. We hypothesized older patients were less likely to receive SSRF nationally. METHODS: The 2016 National Inpatient Sample was used to identify adults with flail chest. Comorbidities and receipt of SSRF were categorized by ICD-10 code. Univariable testing and Multivariable regression were performed to determine the association of demographic characteristics and comorbidities to receipt of SSRF. RESULTS: 1021 patients with flail chest were identified, including 244 (23.9%) who received SSRF. Patients ≥70 years were less likely to receive SSRF. (<70 yrs 201/774 [26.0%] vs ≥70 43/247 [17.4%], P = .006) and had higher risk of death (<70 yrs 39/774 [5.0%] vs ≥70 33/247 [13.4%], P < .001) In multivariable modeling, only age ≥70 years was associated with SSRF (OR .591, P = .005). CONCLUSION: Despite guideline-based support of SSRF in flail chest, SSRF is performed in <25% of patients. Age ≥70 years is associated with lower rate of SSRF and higher risk of death. Future study should examine barriers to SSRF in older patients.

Surgical Rib Fixation in Obese Patients with Isolated Flail Chest Improves Outcomes: A Matched Cohort Study.

BACKGROUND: Obesity is associated with adverse outcomes after major operations. The role of operative rib fixation (RF) in obese patients with flail chest is not clear. The presence of other associated injuries may complicate the interpretation of outcomes. This study compared outcomes after RF to nonoperative management (NOM) in obese patients with isolated flail chest injury. METHODS: Adult obese patients (BMI > 29.9) with flail chest were identified from the Trauma Quality Improvement Program (TQIP) database (2016-2018). Hospital transfers, death within 72 h, and extrathoracic injuries were excluded. RF patients were propensity score matched (1:2) to similar NOM patients. Multivariate regression identified independent factors predicting adverse outcomes. RESULTS: Overall, 367 patients with isolated flail chest who underwent RF were matched with 734 in the NOM group. After matching, the mortality rate was significantly lower in the RF group (1.4% vs. 3.7%; p < 0.05). RF had longer HLOS (15.7 days vs. 12.8 days; p < 0.05) and ICU LOS (10.1 days vs. 8.6 days; p < 0.05), shorter ventilator days (9.2 days vs. 11.5 days; p < 0.05), and a higher rate of venous thromboembolism (7.1% vs. 3.5%, p < 0.05). On multivariate analysis, RF was associated with decreased mortality (OR 0.27; p < 0.05). Early RF (≤ 72 h) was associated with shorter ICU stay and mechanical ventilation. CONCLUSION: RF for isolated flail chest in obese patients is associated with decreased mortality and fewer ventilator days. When performed early, fixation decreases the need for prolonged ventilator use and ICU stay. A more aggressive VTE prophylaxis should be considered in patients undergoing RF.

Cryoablation for Chest Wall Trauma: A Brief Report.

Respiratory failure secondary to rib fractures is a major source of morbidity and mortality in trauma patients, particularly in older populations. Management of pain in these patients is complex due to the nature of the injuries. We present 3 patients who underwent a video-assisted thoracoscopic cryoablation of intercostal nerves for pain control after chest trauma. None of the patients developed post-operative complications related to poor respiratory status such as pneumonia or atelectasis. At one-month clinic follow-up, all patients reported no chest pain and were not using opiate analgesics. In patients for whom there is a contraindication to rib fixation in the setting of unstable rib fractures, cryoablation may be a method by which to improve respiratory status and decrease ventilator dependency due to pain. Cryoablation of intercostal nerves may provide a more durable and clinically feasible solution to aid in the healing process of these patients.

K-Rod: An Innovative Method of Personalized Rib Splinting for Expeditious Management of Flail Chest in Acute Care Settings.

Flail chest is a severe type of multiple rib fracture that can cause ventilation problems and respiratory complications. Historically, flail chest has been mainly managed through pain control and ventilatory support as needed. Operative fixation has recently become popular for the condition, and some studies have revealed its potentially positive effects on the outcomes of patients with flail chest. However, for those for whom surgery is unsuitable, few treatment options, other than simply providing analgesia, are available. Herein, we introduce our innovative method of applying personalized rib splinting for quick management of flail chest, which is easy, tailor-made, and has significant effects on pain reduction.

Concomitant Sternal Fractures: Harbinger of Worse Pulmonary Complications and Mortality in Patients With Rib Fractures.

BACKGROUND: Sternal and rib fractures are common concomitant injuries. However, the impact of concurrent sternal fractures on clinical outcomes of patients with rib fractures is unclear. We aimed to unveil the pulmonary morbidity and mortality impact of concomitant sternal fractures among patients with rib fractures. METHODS: We identified adult patients admitted with traumatic rib fractures with vs. without concomitant sternal fractures using the 2012-2014 National Inpatient Sample (NIS). After 2:1 propensity score matching and adjustment for residual imbalances, we compared risk of pulmonary morbidity and mortality between patients with vs. without concomitant sternal fractures. Subgroup analysis in patients with flail chest assessed whether sternal fractures modify the association between undergoing surgical stabilization of rib fractures (SSRF) and pulmonary morbidity or mortality. RESULTS: Of 475 710 encounters of adults admitted with rib fractures, 24 594 (5%) had concomitant sternal fractures. After 2:1 propensity score matching, patients with concomitant sternal fractures had 70% higher risk (95% CI: 50-90% higher, P < 0.001) of undergoing tracheostomy, 40% higher risk (30-50% higher, P <.001) of undergoing intubation, and 20% higher risk of respiratory failure (10-30% higher, P <.001) and mortality (10-40% higher, P =.007). Subgroup analysis of 8600 patients with flail chest showed concomitant sternal fractures did not impact the association between undergoing SSRF and any pulmonary morbidity or mortality. CONCLUSION: Concomitant sternal fractures are associated with increased risk for pulmonary morbidity and mortality among patients with rib fractures. However, our findings are limited by a binary definition of sternal fractures, which encompasses heterogeneous injury patterns with likely variable clinical relevance.

Multiple rib fractures: does flail chest matter?

BACKGROUND: Recent studies have reported significant morbidity and mortality in patients with multiple rib fractures, even without flail chest. The aim of this study was to compare the clinical outcome and incidence of associated chest injuries between patients with and without flail chest, with three or more rib fractures. METHODS: This study included patients with blunt trauma with at least three rib fractures, hospitalised during 2010-2019 in the Hillel Yaffe Medical Center in central Israel (level II trauma centre). Patients with and without radiologically defined flail chest were compared with regard to demographics, Injury Severity Score (ISS), GCS, systolic blood pressure (SBP) on admission, radiological evidence of flail chest, associated chest injuries, length of stay in intensive care unit, length of hospitalisation and mortality. RESULTS: The study included 407 patients, of which 79 (19.4%) had flail chest. Overall, pneumothorax and haemothorax were more common among patients with flail chest (p<0.05). When comparing patients with three to five rib fractures, there was no difference in length of intensive care and length of hospitalisation or mortality; however, there was a higher incidence of pneumothorax (24.6% vs 50.0%, p<0.05). When comparing patients with six or more rib fractures, no difference was found between patients with and without flail chest. CONCLUSION: In patients with three to five rib fractures, pneumothorax is more common among patients with flail chest. Clinical significance of flail chest in patients with more than six rib fractures is questionable and flail chest may not be a reliable marker for severity of chest injury in patients with more than six fractures.

Nationwide cost-effectiveness analysis of surgical stabilization of rib fractures by flail chest status and age groups.

BACKGROUND: Surgical stabilization of rib fracture (SSRF) is increasingly used to manage patients with rib fractures. Benefits of performing SSRF appear variable, and the procedure is costly, necessitating cost-effectiveness analysis for distinct subgroups. We aimed to assess the cost-effectiveness of SSRF versus nonoperative management among patients with rib fractures younger than 65 years versus 65 years or older, with versus without flail chest. We hypothesized that, compared with nonoperative management, SSRF is cost-effective only for patients with flail chest. METHODS: This economic evaluation used a decision-analytic Markov model with a lifetime time horizon incorporating US population-representative inputs to simulate benefits and risks of SSRF compared with nonoperative management. We report quality-adjusted life years (QALYs), costs, and incremental cost-effectiveness ratios. Deterministic and probabilistic sensitivity analyses accounted for most plausible clinical scenarios. RESULTS: Compared with nonoperative management, SSRF was cost-effective for patients with flail chest at willingness-to-pay threshold of US $150,000/QALY gained. Surgical stabilization of rib fracture costs US $25,338 and US $123,377/QALY gained for those with flail chest younger than 65 years and 65 years or older, respectively. Surgical stabilization of rib fracture was not cost-effective for patients without flail chest, costing US $172,704 and US $243,758/QALY gained for those younger than 65 years and 65 years or older, respectively. One-way sensitivity analyses showed that, under most plausible scenarios, SSRF remained cost-effective for subgroups with flail chest, and nonoperative management remained cost-effective for patients older than 65 years without flail chest. Probability that SSRF is cost-effective ranged from 98% among patients younger than 65 years with flail chest to 35% among patients 65 years or older without flail chest. CONCLUSIONS: Surgical stabilization of rib fracture is cost-effective for patients with flail chest. Surgical stabilization of rib fracture may be cost-effective in some patients without flail chest, but delineating these patients requires further study. LEVEL OF EVIDENCE: Economic/decision, level II.

Surgical stabilization of rib fractures is associated with improved survival but increased acute respiratory distress syndrome.

BACKGROUND: How the surgical stabilization of rib fractures after trauma affects the development of acute respiratory distress syndrome and impacts survival has yet to be determined in a large database. We hypothesized that surgical stabilization of rib fractures would not decrease the incidence of acute respiratory distress syndrome. METHODS: The National Trauma Data Bank was queried for all traumatic rib fractures in 2016. Patients were divided into groups with single rib fractures, multiple rib fractures, and flail chest. Nonoperative therapy was compared with stabilization of rib fractures of 1 to 2 ribs or 3+ ribs. RESULTS: There were 114,972 total patients with rib fractures meeting inclusion criteria, with 5,106 (4.4%) having flail chest, 24,726 (21.5%) having single rib fractures, and 85,140 (74.1%) having multiple rib fractures. Those with flail chest (15.9%) were most likely to get rib plating in comparison to multiple rib fractures (0.9%) and single rib fractures (0.2%); P < .001. On logistic regression, surgical stabilization of rib fractures 1 to 2 ribs (odds ratio: 0.17, 95% confidence interval: 0.10-0.28) or 3+ ribs (odds ratio: 0.17, 95% confidence interval: 0.11-0.28), with nonoperative therapy as the reference was associated with survival. Variables associated with mortality included increasing age, male sex, increasing injury severity score, decreased Glasgow coma scale, requirement of transfusions, and hypotension on admission. Surgical stabilization of rib fractures 3+ ribs (odds ratio: 2.30, 95% confidence interval: 1.58-3.37) was associated with acute respiratory distress syndrome but not 1 to 2 ribs (odd ratio: 1.55, 95% confidence interval: 0.97-2.48). On logistic regression of only patients with flail chest, stabilization of rib fractures was associated with decreased mortality but not increased risk of acute respiratory distress syndrome. CONCLUSION: The increased risk of acute respiratory distress syndrome should be considered in the preoperative assessment for stabilization of rib fractures.

Masquelet Technique for Chest Wall Reconstruction: A Case Report.

CASE: A 33-year-old man with recurrent intrathoracic scapular dislocation due to previous trauma-related chest wall resection successfully underwent the 2-stage induced membrane technique commonly known as the Masquelet technique; this procedure effectively created 2 new ribs that resolved his symptoms. CONCLUSIONS: Techniques for chest wall reconstruction for bone loss are quite limited, and these often consist of filling defects with a layered patch; this often cannot withstand the cyclical respiratory motion. Use of the induced membrane technique appears to carry potential when used in the chest wall, and this report describes a technique by which this procedure can be reliably performed.

Prone ventilation in a patient with severe ARDS having a floating sternum.

Prone ventilation is used to manage patients with refractory hypoxia in the critical care unit. Complex chest trauma and chest drains have been a considered relative contraindication to prone ventilation. To the best of our knowledge, it is hitherto unreported in patients having traumatic floating sternum and acute respiratory distress. We present a brief case report of a patient with floating sternum (complete disruption of sternum) managed successfully by prone position ventilation.

Rib fracture fixation as a tool for extubation in a resource-poor environment.

An elderly female with multiple comorbidities was involved in a pedestrian vehicle accident and sustained blunt chest trauma, arriving at a resource-poor hospital in rural South Africa. She had multiple bilateral rib fractures with a unilateral flail segment that caused her to develop respiratory failure. She was intubated and sent to the intensive care unit (ICU) for ventilation. She developed hospital and ventilator acquired pneumonia. She subsequently had hypoxic arrests on two separate occasions and two failed extubations. Despite inadequate access to provisions, this patient was taken to theatre for rib fracture fixation as an attempt to improve her lung function and get her off the ventilator. She was extubated two days after the procedure and discharged from ICU 4 days thereafter. On her follow-up, she reported that she had returned to normal daily living and tasks.

Surgical Stabilization Improves 30-day Mortality in Patients With Traumatic Flail Chest: A Comparative Case Series at a Major Trauma Center.

OBJECTIVES: To evaluate the outcomes including early mortality after surgical rib fixation using a locking plate system as part of a newly introduced chest trauma pathway. DESIGN: Prospective cohort study with retrospective case-controlled matching with a minimum of 1-year follow-up. SETTING: Regional Level 1 trauma center. PATIENTS/PARTICIPANTS: Consecutive patients undergoing surgical rib fixation were prospectively recruited over a 3-year period (56 patients) and matched to similar patients managed nonoperatively (89 patients) using our local trauma registry. Matching was based on injury severity scores and patient demographics. INTERVENTION: Surgical rib fixation with locking plates. MAIN OUTCOME MEASUREMENTS: The primary outcome measure was 30-day mortality with secondary outcomes of hospital length of stay, intensive care unit length of stay, and patient-reported outcome measures including quality of life (EuroQol-EQ-5D-5L). Official causes of death were obtained from the coroner including postmortem results. RESULTS: There was a significant reduction in 30-day mortality in the fixed patients with 1.8% (1/56) compared to 12.4% (11/89) of the nonfixed patients (P = 0.03). This difference remained significant after further exclusion of other nonsurvivable injuries (P = 0.046). Although hospital length of stay was significantly longer in the fixed group, there was no difference on multivariable analysis. Other secondary outcomes were comparable between the groups with no significant differences in any patient-reported measures. CONCLUSIONS: Mortality was significantly lower in patients who underwent rib stabilization. Quality of life and other patient-reported measures were similar, demonstrating no evidence of detrimental longer-term effects of rib stabilization. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Flail Chest: Influence on Length of Stay and Mortality in Blunt Chest Injury.

Flail chest is used as one of the indicators for rib fixation, which is being performed more frequently. Radiologic and clinical flail chest are not clearly differentiated in published studies and the relationship between radiologic flail chest (RFC) and outcomes are not clearly established. Our study was designed to evaluate the relationship of RFC to outcomes in patients with severe blunt chest injury. Adult patients with severe blunt chest injury admitted between January 1, 2014, and June 30, 2016, were identified retrospectively. Three hundred and eighty-three patients were studied and mortality rate was not significantly different in patients with an RFC diagnosis (5.88%) compared with patients without RFC (3.83%), P = 0.50. Length of stay (LOS) in patients with and without RFC were compared and patients with RFC were found to have a statistically significant increase in both hospital and intensive care unit LOS (P = 0.0178, P < 0.0017). Multivariate analysis confirmed RFC as an independent predictor of increased LOS when compared with the number of rib fractures and displacements. Our study suggests that RFC may drive inappropriate use of rib fixation. This questions the justification of liberal rib fixation based on the perceived high mortality rate of modern flail chest diagnoses.
