RESUMO
INTRODUCTION: Rib fixation for ventilator dependent flail chest patients has become a mainstay of management in major trauma centres. However, the expansion of rib fixation for fractured ribs beyond this remains largely in the hands of enthusiasts with the benefits in non ventilator dependent groups largely unproven. Previous meta-analyses have largely included non-randomised and retrospective data, much of which is now more than two decades out of date. We wanted to perform an updated meta-analysis including only rigorous prospective trials which were randomised. Further we wanted to include quality of life outcomes which have not been previously examined in published meta-analyses. METHODS: This meta-analysis was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines and included randomised controlled trials only, of rib fixation compared to non-operative management in adult patients. RESULTS: Eight studies comprising 752 patients of whom 372 had been randomised to receive rib fixation were included. Benefits of rib fixation were identified with significant reductions in mechanical ventilation and lengths of stay (both ICU and hospital) as well as rates of pneumonia and tracheostomy. No significant benefit in quality of life at 6 months was identified. CONCLUSION: Operative intervention for rib fractures leads to significantly lower rates of pneumonia, lengths of intensive care stay and time on mechanical ventilation compared to non-operative intervention. Further study is needed to investigate quality of life improvements after rib fractures as operative rib fixation expands to non-ventilator dependent groups.

BACKGROUND: There is a lack of studies focusing on long-term chest function after chest wall injury due to cardiopulmonary resuscitation (CPR). The purpose of this cross-sectional study was to investigate long-term pain, lung function, physical function, and fracture healing after manual or mechanical CPR and in patients with and without flail chest. METHODS: Patients experiencing out-of-hospital cardiac arrest between 2013 and 2020 and transported to Sahlgrenska University Hospital were identified. Survivors who had undergone a computed tomography (CT) showing chest wall injury were contacted. Thirty-five patients answered a questionnaire regarding pain, physical function, and quality of life and 25 also attended a clinical examination to measure the respiratory and physical functions 3.9 (SD 1.7, min 2-max 8) years after the CPR. In addition, 22 patients underwent an additional CT scan to evaluate fracture healing. RESULTS: The initial CT showed bilateral rib fractures in all but one patient and sternum fracture in 69 %. At the time of the follow-up none of the patients had persistent pain, however, two patients were experiencing local discomfort in the chest wall. Lung function and thoracic expansion were significantly lower compared to reference values (FVC 14 %, FEV1 18 %, PEF 10 % and thoracic expansion 63 %) (p < 0.05). Three of the patients had remaining unhealed injuries. Patients who had received mechanical CPR in additional to manual CPR had a lower peak expiratory flow (80 vs 98 % of predicted values) (p=0.030) =0.030) and those having flail chest had less range of motion in the thoracic spine (84 vs 127 % of predicted) (p = 0.019) otherwise the results were similar between the groups. CONCLUSION: None of the survivors had long-term pain after CPR-related chest wall injuries. Despite decreased lower lung function and thoracic expansion, most patients had no limitations in physical mobility. Only minor differences were seen after manual vs. mechanical CPR or with and without flail chest.

BACKGROUND: Very large chest wall resections can lead to acute thoracic insufficiency syndrome due to the interdependence of lung expansion and thoracic volume. Chest wall tumor surgeries often encounter complications, with the size of the chest wall defect being a significant predictor. Several methods for large chest wall reconstruction have been described, aiming to provide stability, prevent flail chest, and ensure airtight closure. However, no single method fulfills all requirements. Composite chest wall reconstruction using titanium plates and Gore-Tex patches has shown the potential to minimize physiologic abnormalities caused by extensive defects. CASE PRESENTATION: A 42-year-old man with myxofibrosarcoma underwent multiple surgeries, chemotherapies, and radiation therapies due to repeated local recurrences. After right arm amputation and resection of the right third to fifth ribs, a local recurrence was detected. A 30 × 40 cm chest wall defect was resected en bloc, and a titanium plate was used for three-dimensional formability, preventing flail chest and volume loss. The Gore-Tex patch was then reconstructed into an arch shape, allowing lateral thoracic mobility. The patient recovered well and did not experience respiratory dysfunction or local recurrence but later succumbed to distant metastasis. CONCLUSIONS: In this case, the combination of a titanium plate and a Gore-Tex patch proved effective for reconstructing massive lateral chest wall defects. The approach provided stability, preserved thoracic volume, and allowed for lateral mobility. While the patient achieved a successful outcome in terms of local recurrence and respiratory function, distant metastasis remained a challenge for myxofibrosarcoma patients, and its impact on long-term prognosis requires further investigation. Nevertheless, the described procedure offers promise for managing extensive chest wall defects.

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.

INTRODUCTION: We aimed to examine impact of trauma center (TC) surgical stabilization of rib fracture (SSRF) volume on outcomes of patients undergoing SSRF. METHODS: Blunt rib fracture patients who underwent SSRF were included from ACS-TQIP2017-2021. TCs were stratified according to tertiles of SSRF volume:low (LV), middle, and high (HV). Outcomes were time to SSRF, respiratory complications, prolonged ventilator use, mortality. RESULTS: 16,872 patients were identified (LV:5470,HV:5836). Mean age was 56 years, 74% were male, median thorax-AIS was 3. HV centers had a lower proportion of patients with flail chest (HV41% vs LV50%), pulmonary contusion (HV44% vs LV52%) and had shorter time to SSRF(HV58 vs LV76 âh), less respiratory complications (HV3.2% vs LV4.5%), prolonged ventilator use (HV15% vs LV26%), mortality (HV2% vs LV2.6%) (all p â< â0.05). On multivariable regression analysis, HV centers were independently associated with reduced time to SSRF(ß â= â-18.77,95%CI â= â-21.30to-16.25), respiratory complications (OR â= â0.67,95%CI â= â0.49-0.94), prolonged ventilator use (OR â= â0.49,95%CI â= â0.41-0.59), but not mortality. CONCLUSIONS: HV SSRF centers have improved outcomes, however, there are variations in threshold for SSRF and indications must be standardized. LEVEL OF EVIDENCE: Level III. STUDY TYPE: Therapeutic/Care Management.

BACKGROUND: Obesity is a global health issue with increasing prevalence. Surgical procedures, such as surgical stabilization of rib fractures (SSRF), may be affected by obesity-related complications. The objective of the study is to investigate the effects of obesity on SSRF outcomes in multiple rib fractures. METHODS: This retrospective study analyzed data from adults aged ≥ 20 years in the Nationwide Inpatient Sample (NIS) database diagnosed with multiple rib fractures who underwent SSRF between 2005 and 2018. It investigated the relationship between obesity and in-patient outcomes, such as discharge status, length of stay (LOS), in-hospital mortality, hospital costs, and adverse events using logistic and linear regression analyses. RESULTS: Analysis of data from 1,754 patients (morbidly obese: 87; obese: 106; normal weight: 1,561) revealed that morbid obesity was associated with longer LOS (aBeta = 0.07, 95% CI: 0.06, 0.07), higher hospital costs (aBeta = 47.35, 95% CI: 38.55, 56.14), increased risks of adverse events (aOR = 1.63, 95% CI: 1.02, 2.61), hemorrhage/need for transfusion (aOR = 1.77, 95% CI: 1.12, 2.79) and mechanical ventilation ≥ 96 hours (aOR = 2.14, 95% CI: 1.28, 3.58) compared to normal weight patients. Among patients with flail chest, morbid obesity was significantly associated with tracheostomy (aOR = 2.13, 95% CI: 1.05, 4.32), ARDS/respiratory failure (aOR = 2.01, 95% CI: 1.09, 3.70), and mechanical ventilation ≥ 96 hours (aOR = 2.80, 95% CI: 1.47, 5.32). In contrast, morbid obesity had no significant associations with these adverse respiratory outcomes among patients without a flail chest (p > 0.05). CONCLUSIONS: Morbid obesity is associated with adverse outcomes following SSRF for multiple rib fractures, especially for flail chest patients.

BACKGROUND: Rib fracture nonunion is a probable cause of chronic pain following chest trauma, although its prevalence remains unknown. The aims of this study were to determine rib fracture nonunion prevalence following nonoperative management and to determine if presence of nonunion was associated with the number of rib fractures, or the rib fracture classification of anatomical location, type, and displacement. METHODS: This multicenter prospective cohort study included trauma patients with three or more fractured ribs but without a flail segment, who participated in the nonoperative management group of the FixCon trial between January 2019 and June 2022. The number and classification of rib fractures were assessed on trauma chest CT. Chest CTs conducted six months post-trauma were evaluated for the presence of nonunion. Radiological characteristics of nonunions were compared with normally healed rib fractures using the Mann-Whitney U, χ2 test, and Fisher's exact test as appropriate. A generalized linear model adjusted for multiple observations per patient when assessing the associations between nonunion and fracture characteristics. RESULTS: A total of 68 patients were included with 561 post-traumatic fractures in 429 ribs. Chest CT after six months revealed nonunions in 67 (12 %) rib fractures in 29 (43 %) patients with a median of 2 (P25-P75 1-3) nonunions per patient. Nonunion was most commonly observed in ribs seven to 10 (20-23 %, p < 0.001, adjusted p = 0.006). Nonunion occurred in 14 (5 %) undisplaced, 22 (19 %) offset, and 20 (23 %) displaced rib fractures (p < 0.001). No statistically significant association between rib fracture type and nonunion was found. CONCLUSIONS: Forty-three percent of patients with multiple rib fractures had radiographic nonunion six months after trauma. Fractures in ribs seven to 10 and dislocated fractures had an increased risk of rib fracture nonunion.

The impact of energy on the thorax can lead to serial rib fractures, sternal fractures, the combination of both and to injury of intrathoracic organs depending on the type, localization and intensity. Sometimes this results in chest wall instability with severe impairment of the respiratory mechanics. In the last decade the importance of surgical chest wall reconstruction in cases of chest wall instability has greatly increased. The evidence for a surgical approach has in the meantime been supported by prospective randomized multicenter studies, multiple retrospective data analyses and meta-analyses based on these studies, including a Cochrane review. The assessment of form and severity of the trauma and the degree of impairment of the respiratory mechanism are the basis for a structured decision on an extended conservative or surgical reconstructive strategy as well as the timing, type and extent of the operation. The morbidity (rate of pneumonia, duration of intensive care unit stay and mechanical ventilation) and fatality can be reduced by a timely surgery within 72â¯h after trauma. In this article the already established and evidence-based algorithms for surgical chest wall reconstruction are discussed in the context of the current evidence.

BACKGROUND: Given the lack of high-quality data on patient selection for surgical stabilization of rib fractures (SSRF), significant variability in practice likely exists across trauma centers. We aimed to determine whether centers with a more liberal approach to SSRF had improved outcomes. METHODS: We performed a retrospective cohort study of adult patients with flail chest admitted to Level I or II trauma centers participating in the American College of Surgeons' Trauma Quality Improvement Program. The primary outcome was hospital mortality; secondary outcomes included discharge status, tracheostomy, duration of mechanical ventilation, and hospital length of stay. Logistic regression was performed to calculate center-level observed/expected rates of SSRF and centers were grouped into quintiles from "most liberal" to "most restrictive." Multivariable regression was used to determine the association between these quintiles and outcomes. We also used an instrumental variable analysis to evaluate the association between SSRF and mortality at the patient level. RESULTS: Among 23,619 patients with flail chest across 354 centers, 22% underwent SSRF. Center rates of fixation ranged from 0% to 88%. Higher rates of SSRF were not associated with lower mortality overall (highest vs. lowest quintile: odds ratio, 0.86; 95% confidence interval, 0.63-1.17). However, centers with a more liberal approach to SSRF had lower rates of independent status at discharge, higher tracheostomy rates, longer duration of mechanical ventilation, and longer hospital and ICU length of stay. The patient level analysis demonstrated that SSRF as was associated with a 25% lower risk of death. CONCLUSION: Overall, centers with a liberal approach to SSRF do not show improved outcomes among patients with a flail chest, but have higher resource utilization. Results at the patient level suggest that there is a population likely to benefit but these patients remain to be identified through further research. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level III.

INTRODUCTION: The anterior stove-in chest (ASIC) is a rare form of flail chest involving bilateral rib or sternal fractures resulting in an unstable chest wall that caves into the thoracic cavity. Given ASIC has only been described in a handful of case reports, this study sought to review our institution's experience in the surgical management of ASIC injuries. METHODS: A retrospective review of patients with ASIC was conducted at our level I trauma center from 1//2021 to 3//2023. Information pertaining to patient demographics, fracture pattern, operative management, and outcomes was obtained and compared across patients in the case series. RESULTS: 6 patients met inclusion criteria, all males aged 37-78 years. 5 suffered motor vehicle collisions, and 1 was a pedestrian struck by an automobile. The median injury severity score was 28. All received ORIF within 5 days of admission, most commonly for ongoing respiratory distress. Patients 2 and 4 underwent bilateral ORIF of the ribs and sternum while patients 1, 5, and 6 underwent left-sided repair. Patient 3 required ORIF of left ribs and the sternum to stabilize their injuries. 5 of 6 patients were liberated from the ventilator and survived to discharge. CONCLUSIONS: This study demonstrates successful operative management of 6 patients with ASIC and suggests that early operative intervention with ORIF for affected segments may improve respiratory mechanics, ability to wean from the ventilator, and overall survival. Further research is needed to generate standardized guidelines for the management of this uncommon and complex thoracic injury.

RATIONALE AND OBJECTIVES: The aim of this study was to compare the use of computed tomography (CT) with automatic rib unfolding and three-dimensional (3D) volume-rendered imaging in the detection and characterization of rib fractures and flail chest. MATERIALS AND METHODS: A total of 130 patients with blunt chest trauma underwent whole-body CT, and five independent readers assessed the presence and characterization of rib fractures using traditional CT images, automatic rib unfolding, and 3D volume-rendered images in separate readout sessions at least 2 weeks apart. A gold standard was established by consensus among the readers based on the combined analysis of conventional and reformatted images. RESULTS: Automatic rib unfolding significantly reduced mean reading time by 47.5%-74.9% (P < 0.0001) while maintaining a comparable diagnostic performance for rib fractures (positive predictive value [PPV] of 82.1%-93.5%, negative predictive value [NPV] of 96.8%-98.2%, and 69.4%-94.2% and 96.9%-99.1% for conventional axial images and 70.4%-85.1% and 95.2%-96.6% for 3D images) and better interobserver agreement (kappa of 0.74-0.87). For flail chest, automatic rib unfolding showed a PPV of 85.7%-100%, NPV of 90.4%-99.0%, and 80.0%-100% and 89.7%-100% for conventional axial images and 76.9%-100% and 89.0%-92.1% for 3D images. CONCLUSION: Automatic rib unfolding demonstrated equivalent diagnostic performance to conventional images in detecting acute rib fractures and flail chest, with good interobserver agreement and time-saving benefits.

BACKGROUND: Often missed in blunt chest wall injury, costal cartilage injuries can cause chest wall instability, refractory pain, and deformity. Notably, there is only a small amount of evidence regarding hardware performance when applied to costal cartilage. In a prior multicenter study, hardware failure rate was found to be approximately 3% following surgical stabilization of rib fractures (SSRFs) for all fracture locations. The aim of the current study was to evaluate hardware performance for costal cartilage injuries. METHODS: All patients undergoing SSRF performed at our institution from 2016 to 2022 were queried, including both acute and chronic injuries. Both radiographic and clinical follow-up were retrospectively reviewed to evaluate for hardware failure defined as plate fracture, malposition, or screw migration following cartilage fixation. RESULTS: After screening 359 patients, 43 were included for analysis. Mean age was 64 years, and 67% of patients were male. Median number of fractures per patient was 7 with 60% of patients sustaining a flail chest injury pattern. Median total plates per operation was 6 and median costal cartilage plates was 3. In total, 144 plates were applied to the costal cartilage for the group. Mean follow-up was as follows: clinical 88 days, two-view plain radiography 164 days, and chest computed tomography 184 days. Hardware failure was observed in 3 of 144 plates (2.1%), in three separate patients. Two cases were asymptomatic and did not require intervention. One patient required revisional operation in the acute setting. CONCLUSION: In our institution, hardware failure for costal cartilage fractures was observed to be 2.1%. This aligns with prior reports of hardware failure during SSRF for all injury locations. Surgical stabilization of anterior and cartilaginous chest wall injury with appropriate plate contouring and fixation technique appears to provide adequate stabilization with a relatively low rate of hardware malfunction. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level V.

Traumatic injuries of the thorax can entail thoracic wall instability (flail chest), which can affect both the shape of the thorax and the mechanics of respiration; however, so far little is known about the biomechanics of the unstable thoracic wall and the optimal surgical fixation. This review article summarizes the current state of research regarding experimental models and previous findings. The thoracic wall is primarily burdened by complex muscle and compression forces during respiration and the mechanical coupling to spinal movement. Previous experimental models focused on the burden caused by respiration, but are mostly not validated, barely established, and severely limited with respect to the simulation of physiologically occurring forces. Nevertheless, previous results suggested that osteosynthesis of an unstable thoracic wall is essential from a biomechanical point of view to restore the native respiratory mechanics, thoracic shape and spinal stability. Moreover, in vitro studies also showed better stabilizing properties of plate osteosynthesis compared to intramedullary splints, wires or screws. The optimum number and selection of ribs to be fixated for the different types of thoracic wall instability is still unknown from a biomechanical perspective. Future biomechanical investigations should simulate respiratory and spinal movement by means of validated models.

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.

INTRODUCTION: Traumatic chest wall injuries are common however the incidence of non-union rib fractures is unknown. Previous studies have suggested that surgical management of symptomatic non-union rib fractures could be beneficial in selected patients, although many experience persisting pain despite surgery. The aim of this study is to investigate the long-term outcome after surgical management of symptomatic non-union rib fractures. METHODS: This is a cross-sectional study including adults (≥18 years) managed surgically for symptomatic non-union rib fractures with plate fixation during the period 2010-2020 at Sahlgrenska University Hospital. Patients operated for acute chest wall injury or injury due to cardiopulmonary resuscitation were excluded. Patients answered standardized questionnaires concerning remaining symptoms and satisfaction with surgery, quality of life (QoL, EQ-5D-5 L) and disability (Disability Rating Index, DRI). Lung function, movement of chest wall and thoracic spine, and shoulder function (Boström index) were assessed. RESULTS: Sixteen patients, 12 men and four women, with mean age 61.6± 11.1 were included in the study. The mechanism of injury was trauma in 10 patients and cough-induced injuries in five patients. Lung disease was significantly more prevalent in cough-induced injuries compared to traumatic injuries, 5 vs 1 (p = 0.008). The mean follow-up time was 3.5 years. Ninety-four percent were satisfied with the surgery and reported that their symptoms had decreased, although 69 % had remaining symptoms, especially pain, from the chest wall. Quality of Life was decreased with EQ-5D-5 L index 0.819 (0.477-0.976) and EQ-VAS 69 (10-100). Disability Rating Index was 31.5 (1.3-76.7) with problems running, lifting heavy objects, and performing heavy work. Predicted lung function was decreased with Forced Vital Capacity (FVC) 86.2 ± 14.2 %, Forced Expiratory Volume in 1 second (FEV1) 79.1 ± 10.7 % and Peak Expiratory Flow (PEF) 89.7 ± 14.5 %. Patients with cough-induced injuries had full shoulder mobility. CONCLUSIONS: Chest wall surgery for symptomatic non-union rib fractures results in decreased symptoms and patient satisfaction in most cases despite remaining symptoms, reduced lung function, chest wall movement, and QoL and persistent disability.

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.

Early surgical stabilization of rib fracture (SSRF) improves outcomes in patients with flail physiology and severely displaced fractures. We present two cases of patients with severe chest injury and large flail segment who underwent SSRF while on veno-venous extracorporeal membrane oxygenation (VV-ECMO). The patients developed respiratory failure within 24 hours of admission requiring VV-ECMO. The extent of their chest wall injury limited pulmonary mechanics prohibiting transition off VV-ECMO. Therefore, SSRF was performed on hospital days 2 and 3 and while on VV-ECMO support. Stabilizing the chest wall allowed for improved ventilation and successful decannulation from VV-ECMO on postoperative days 3 and 4. Ultimately, both achieved a functional recovery and were discharged home. These cases demonstrate a unique thoracic damage control strategy wherein SSRF is performed while on VV-ECMO. Improving chest stability and pulmonary mechanics with SSRF allowed for safe transition off VV-ECMO and achieved a favorable long-term outcome.

INTRODUCTION: Flail chest (FC) after blunt trauma is associated with significant morbidity and prolonged hospitalizations. The goal of this study was to examine the relationship between timing of rib fixation (ORIF) and pulmonary morbidity and mortality in patients with FC. METHODS: FC patients were identified from the Trauma Quality Improvement Program database over 3-year, ending 2019. Demographics, severity of injury and shock, time to ORIF, pulmonary morbidity, and mortality were recorded. Youden's index identified optimal time to ORIF. Patients were compared based on undergoing ORIF versus nonoperative management, then for patients undergoing ORIF based on time from admission to operation, utilizing Youden's index to determine the preferred time for fixation. Multivariable logistic regression determined predictors of pulmonary morbidity and mortality. RESULTS: 20,457 patients were identified: 3347 (16.4%) underwent ORIF. The majority were male (73%) with median age and injury severity score of 58 and 22, respectively. Patients undergoing ORIF were clinically similar to those managed nonoperatively but had increased pulmonary morbidity (27.6 versus 15.2%, P < 0.0001) and reduced mortality (2.9 versus 11.7%, P < 0.0001). Multivariable logistic regression identified ORIF as the only modifiable risk factor significantly associated with reduced mortality (odds ratio: 0.26; 95% CI:0.21-0.32, P < 0.0001). Youden's index identified the inflection point for time to ORIF as 4 d postinjury: EARLY (≤4 d) and LATE (>4 d). EARLY fixation was associated with a significant decrease in ventilator days, intensive care unit and hospital length of stay, and pulmonary morbidity. CONCLUSIONS: Patients undergoing ORIF for FC experienced increased pulmonary morbidity; however, had an associated reduced mortality benefit compared to the nonoperative cohort. EARLY ORIF was associated with a reduction in pulmonary morbidity, without impacting the mortality benefit found with ORIF. Thus, for patients with FC, ORIF performed within 4 d postinjury may help reduce pulmonary morbidity, length of stay, and mortality.

BACKGROUND: Multiple rib fractures can lead to flail chest with up to 35% mortality rate due to severe pulmonary complications. Current treatments of flail chest remain controversial. Studies have shown that surgical treatments can improve outcomes and reduce mortality, comparing to non-operative treatments. Current surgical fixation methods focus on stabilization of ribs on the outward facing side, and they require division of intercostal muscles. Damages to surrounding nerves and vessels may lead to chronic pain. This study tests a novel interior fixation method that minimizes neurovascular injuries. METHODS: Twelve healthy canines were divided in two surgical operation groups for exterior and interior fixation using titanium metal plates. Osteotomy with oblique fractures was prepared under general anesthesia. Exterior fixation was performed in open surgery. Interior fixation was minimally invasive using custom made tools including a flexible shaft extension screwdriver, solid plate stand, guiding wire loop and metal plates with threaded holes. RESULTS: Respiratory and cardiovascular functions (RR, PO2, PCO2, SpO2, and HR) together with body temperature were measured before anesthesia and within 48 h after surgery. The difference in measurements was not statistically significant between the two groups before surgery with P values greater than 0.05. However, the interior group canines had better RR and PO2 values starting from the 24th hour, and better PCO2, SpO2, and HR values starting from the 48th hour. It took longer operation time to complete the minimally invasive interior fixation surgery (P value less than 0.001), but the total blood loss was less than the exterior fixation group (P value less than 0.001). Results also showed that interior group canines suffered less pain, and they had quicker recovery in gastrointestinal and physical mobility. CONCLUSIONS: The investigative interior fixation method was safe and effective in rib stabilization on a canine rib fracture model, comparing to the exterior fixation method. The interior fixation was minimally invasive, with less damages to tissues and nerves surrounding the ribs, leading to better postoperative outcomes.

Background and Objectives: Protective equipment, including seatbelts and airbags, have dramatically reduced the morbidity and mortality rates associated with motor vehicle collisions (MVCs). While generally associated with a reduced rate of injury, the effect of motor vehicle protective equipment on patterns of chest wall trauma is unknown. We hypothesized that protective equipment would affect the rate of flail chest after an MVC. Materials and Methods: This study was a retrospective analysis of the 2019 iteration of the American College of Surgeons Trauma Quality Program (ACS-TQIP) database. Rib fracture types were categorized as non-flail chest rib fractures and flail chest using ICD-10 diagnosis coding. The primary outcome was the occurrence of flail chests after motor vehicle collisions. The protective equipment evaluated were seatbelts and airbags. We performed bivariate and multivariate logistic regression to determine the association of flail chest with the utilization of vehicle protective equipment. Results: We identified 25,101 patients with rib fractures after motor vehicle collisions. In bivariate analysis, the severity of the rib fractures was associated with seatbelt type, airbag status, smoking history, and history of cerebrovascular accident (CVA). In multivariate analysis, seatbelt use and airbag deployment (OR 0.76 CI 0.65-0.89) were independently associated with a decreased rate of flail chest. In an interaction analysis, flail chest was only reduced when a lap belt was used in combination with the deployed airbag (OR 0.59 CI 0.43-0.80) when a shoulder belt was used without airbag deployment (0.69 CI 0.49-0.97), or when a shoulder belt was used with airbag deployment (0.57 CI 0.46-0.70). Conclusions: Although motor vehicle protective equipment is associated with a decreased rate of flail chest after a motor vehicle collision, the benefit is only observed when lap belts and airbags are used simultaneously or when a shoulder belt is used. These data highlight the importance of occupant seatbelt compliance and suggest the effect of motor vehicle restraint systems in reducing severe chest wall injuries.
