RESUMEN
OBJECTIVE: Most car occupant fatalities occur in frontal crashes and the thorax is the most frequently injured body region. The objectives of the study were, firstly, to quantify the relation between risk factors (such as speed and occupant age) and rib and sternum fracture injury probability in frontal car crashes, and, secondly, to evaluate whether rib fracture occurrence can predict sternum fractures. METHODS: Weighted German data from 1999-2021 were used to create the injury risk curves to predict both, at least moderate and at least serious, rib and sternum fracture risks. A contingency table for rib and sternum fractures allowed the calculation of sensitivity, specificity, and precision, as well as testing for the association. RESULTS: Elderly occupants (≥65 years old) had increased rib and sternum fracture risk compared to mid aged occupants (18-64 years old). Besides occupant age, delta-V was always and sex sometimes a significant predictor for skeletal thoracic injury. Sternum fractures were more common than rib fractures and more likely to occur at any given delta-V. Sternum fractures occurred often in isolation. Female occupants were at higher risk than males to sustain at least moderate rib and sternum fractures together and sternum fractures in isolation. Rib and sternum fractures were associated, but low sensitivity and precision show that rib fractures do not predict sternum fractures well. CONCLUSIONS: Elderly and female occupants were at the highest risk and should be targeted by thoracic injury criteria and thresholds for frontal crash occupant protection. Rib and sternum fractures were not associated. Therefore, sternum fractures need to be predicted and evaluated separately from rib fractures.

BACKGROUND: This study aimed to determine the incidence and influencing factors of venous thromboembolism (VTE) in patients with traumatic rib fractures. METHODS: The retrospective study analyzed medical records of patients with traumatic rib fractures from 33 hospitals. RESULTS: The overall incidence of VTE in hospitalized patients with traumatic rib fractures was 8.1%. Patients with isolated traumatic rib fractures had a significantly lower incidence of VTE (4.4%) compared to patients with rib fractures combined with other injuries (12.0%). Multivariate analysis identified the number of rib fractures as an independent risk factor for thrombosis. Surgical stabilization of isolated rib fractures involving three or more ribs was associated with a lower VTE incidence compared to conservative treatment. CONCLUSIONS: Patients with rib fractures have a higher incidence of VTE, positively correlated with the number of rib fractures. However, the occurrence of thrombosis is relatively low in isolated rib fractures. Targeted thromboprophylaxis strategies should be implemented for these patients, and surgical stabilization of rib fractures may be beneficial in reducing the risk of VTE.

INTRODUCTION: Fractures of the ribs and sternum are associated with significant morbidity and mortality. Characterization of the injury burden across England is necessary to inform and evaluate developments in trauma care and infrastructure, however is yet to be comprehensively undertaken. Therefore, the aim of this study was to describe trends in the incidence of sternal and rib fractures across England between 1990 and 2019. MATERIALS AND METHODS: Age-standardised incidence rates (ASIRs) for rib and sternal fractures in males and females were extracted from the 2019 Global Burden of Disease (GBD) study by all causes, falls and road traffic collisions for 9 sub-regions of England. Temporal trends within the study period were analysed using Joinpoint regression analysis. RESULTS: The overall ASIRs in England in 2019 were 30.34/100,000 and 46.02/100,000 for females and males, respectively. Between 1990 and 2019, the estimated overall percentage change across England was +0.20 % among females and -7.05 % among males. A statistically significant increase in ASIR was observed in all 9 sub-regions of England among females from 2014-2019 (p<0.001). Among males, a statistically significant increase in ASIR was observed in 7 of the 9 regions from 2014-2019 (p<0.001) and in the remaining 2 regions from 2015-2019 (p<0.001). DISCUSSION: Increasing ASIRs of rib and sternal fractures were observed among females and decreasing ASIRs among males, with overall ASIRs higher among males. Developments in trauma infrastructure and associated variations in diagnostic and management strategies over the observation period likely contribute to changes in the national injury burden. The findings are suggestive of the importance of ongoing financial investment in trauma infrastructure and of clear clinical guidelines to manage an increasing national injury burden.

OBJECTIVE: The objective of this study is to compare patients with severe and mild blunt thoracic trauma, who survived an earthquake and presented to the emergency department (ED), in order to identify factors influencing the severity of trauma in earthquake-related thoracic injuries. METHODS: This retrospective, cross-sectional, observational comparative study included patients with isolated thoracic injuries due to the February 6th Kahramanmaras earthquake. The patients were categorized into severe and mild groups based on chest trauma scoring (CTS), and their characteristics were compared. RESULTS: The study included 53 patients, with 43 (88.1%) classified as having mild thoracic trauma and 10 (18.9%) classified as having severe thoracic trauma. There was no significant difference in the duration of entrapment between the groups (p = 0.824). The incidence of hemothorax, pneumothorax, rib fractures, and pneumomediastinum did not differ significantly between the two groups (p > 0.05). However, severe thoracic trauma was associated with a higher rate of lung contusion compared to the mild group (p = 0.045). The severe group exhibited significantly higher median scores for lung contusion, rib fractures, and total CTS compared to the mild group (p < 0.001). The mortality rate was significantly higher in the severe group (40%, n = 4) compared to the mild group (2.3%, n = 1) (p = 0.003). CONCLUSION: The duration of entrapment did not significantly affect the severity of thoracic injuries in earthquake-related blunt thoracic trauma. However, lung contusion was found to be a more prominent feature in these injuries compared to other clinical conditions such as hemothorax and pneumothorax. These findings highlight the distinct clinical implications of earthquake-related thoracic trauma and may have implications for management strategies in these cases.

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.

BACKGROUND: Although much is published reporting clinical outcomes in the patients with blunt chest wall trauma who are admitted to hospital from the ED, less is known about the patients' recovery when they are discharged directly without admission. The aim of this study was to investigate the health care utilization outcomes in adult patients with blunt chest wall trauma, discharged directly from ED in a trauma unit in the United Kingdom. METHODS: This was a longitudinal, retrospective, single-center, observational study incorporating analysis of linked datasets, using the Secure Anonymised Information Linkage databank for admissions to a trauma unit in the Wales, between January 1, 2016, and December 31, 2020. All patients 16 years or older with a primary diagnosis of blunt chest wall trauma discharged directly home were included. Data were analyzed using a negative binomial regression model. RESULTS: There were 3,205 presentations to the ED included. Mean age was 53 years, 57% were male, with the predominant injury mechanism being a low velocity fall (50%). 93% of the cohort sustained between 0 and 3 rib fractures. Four percent of the cohort were reported to have chronic obstructive pulmonary disease, and 4% using preinjury anticoagulants. On regression analysis, inpatient admissions, outpatient appointments and primary care contacts all significantly increased in the 12-week period postinjury, compared with the 12-week period preinjury (odds ratio [OR], 1.63; 95% confidence interval [CI], 1.33-1.99; p < 0.001; OR, 1.28; 95% CI, 1.14-1.43; p < 0.001; OR, 1.02; 95% CI, 1.01-1.02; p < 0.001, respectively). Risk of health care resource utilization increased significantly with each additional year of age, chronic obstructive pulmonary disease and preinjury anticoagulant use (all p < 0.05). Social deprivation and number of rib fracture did not impact outcomes. CONCLUSION: The results of this study demonstrate the need for appropriate signposting and follow-up for patients with blunt chest wall trauma presenting to the ED, not requiring admission to the hospital. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level IV.

OBJECTIVE: In 2020, 17% of all crash fatalities were individuals aged 65 years or older. Crash data also revealed that for older occupants, thoracic related injuries are among the leading causes of fatality. Historically, the majority of near-side impact postmortem human subjects (PMHS) studies used a generic load wall to capture external loads that were applied to PMHS. While these data were helpful in documenting biofidelity, they did not represent a realistic response an occupant would undergo in a near-side crash. The objective of this research was to test small, elderly female PMHS in a repeatable, realistic near-side impact crash scenario to investigate current injury criteria as they relate to this vulnerable population. METHOD: Ten small, elderly PMHS were subjected to a realistic near-side impact loading condition. The PMHS were targeted to be elderly females age 60+, approximately 5th percentile in height and weight, with osteopenic areal bone mineral density. Each subject was seated on a mass-production seat, equipped with a side airbag and standard three-point restraint with a pretensioner. Other boundary conditions included an intruding driver's side door. PMHS instrumentation included strain gages on ribs 3-10 bilaterally to identify fracture timing. Two chestbands were used to measure chest deflection, one at the level of the axilla and one at the level of the xiphoid process. RESULTS: Injuries observed included rib fractures, particularly on the struck side, and in multiple cases a flail chest was observed. Eight of ten subjects resulted in AIS3+ thoracic injuries, despite previously tested ATDs predicting less than a 10% chance of AIS3+ injury. Subjects crossed the threshold for AIS3 injury in the range of only 1% - 9% chest compression. Additionally, mechanisms of injury varied, as some injuries were incurred by door interactions while others came during airbag interactions. CONCLUSIONS: This research points to two areas of concern that likely require further analysis: (1) the appropriateness of potentially oversimplified PMHS testing to establish injury thresholds and define injury criteria for complicated crash scenarios; (2) the importance of identifying the precise timing of injuries to better understand the effect of current passive restraint systems.

BACKGROUND: Thoracic trauma is associated with a high morbidity and mortality. Assessing the risk for complications is essential for planning the further treatment strategies and managing resources in thoracic trauma. OBJECTIVE: The aim of the study was to analyze concomitant injuries in unilateral and bilateral rib fractures and pulmonary contusions and evaluate differences in complication rates between the two. MATERIAL AND METHODS: In a retrospective study, data from all patients diagnosed with thoracic trauma at a level I trauma center were analyzed. Bivariate and multivariate analysis were used to examine an association of unilateral or bilateral rib fractures, serial rib fractures, and pulmonary contusions with multiple injuries and outcomes. In addition, multivariate regression analysis was utilized to determine the impact of age, gender and additional injuries on outcome. RESULTS: A total of 714 patients were included in the analysis. The mean Injury Severity Score (ISS) was 19. Patients with an additional thoracic spine injury had a significantly higher incidence of bilateral rib fractures. Pulmonary contusions were associated with younger age. Abdominal injuries were predictors for bilateral pulmonary contusions. Complications occurred in 36% of the patients. Bilateral injuries increased the complication rate up to 70%. Pelvic and abdominal injuries as well as the need for a chest drain were significant risk factors for complications. The mortality rate was 10%, with higher age, head and pelvic injuries as predictors. CONCLUSION: Patients with bilateral chest trauma had an increased incidence of complications and a higher mortality rate. Bilateral injuries and significant risk factors must therefore be considered. Injury of the thoracic spine should be excluded in those patients.

INTRODUCTION: Thoracic trauma represents a significant burden of disease in Aotearoa, New Zealand (AoNZ). To date, no study has examined the incidence or outcomes of patients suffering major thoracic trauma, or major trauma and rib fractures in AoNZ. METHODS: A 6 year retrospective study of all major trauma (Injury Severity Score >12) patients in AoNZ was performed. The National Trauma Registry was searched to identify patients. The National Minimum Data Set was searched for all ICD-10 codes associated with surgical stabilisation of rib fractures (SSRF). Poisson regression was used to determine the change in incidence rate over the study period adjusted for age with the logarithm of population size as the offset variable. The incidence rate ratios (IRR) with 95% confidence intervals (CI) were reported. RESULTS: 12,218 patients sustained major trauma. 7,059 (57.8%) of these patients sustained thoracic injuries. Of these patients, 5,585 (79.1%) sustained rib fractures, and 180 (3.2%) proceeded to SSRF. A flail segment was observed in 16% of patients with rib fractures. Transport was the mechanism of injury in 53% of patients. During the study the incidence (cases per 100,000 people per year) of major trauma increased from 39.5 to 49.3 (IRR 1.05, 95%CI 1.04 to 1.07, <0.001), the incidence of thoracic injuries from 21.3 to 28.7 (1.07, 95% CI 1.05 to 1.08, <0.001) and the incidence of rib fractures from 16.0 to 22.9 (1.08, 95% CI 1.06 to 1.09, <0.001). SSRF was performed in 3.2% of patients with rib fractures and increased from 0.2 to 0.8 cases per 100,000 people per year (1.27, 95% CI 1.15 to 1.41, <0.001) during the study. CONCLUSION: This study reports the incidence of major trauma patients with thoracic injury, major trauma patients with rib fractures and the incidence of SSRF in AoNZ. Transport related injuries are the predominant mechanism of injury. The incidence of SSRF was low across AoNZ. To improve the quality of care in AoNZ for major trauma patients with rib fractures, consideration should be made to create national guidelines and robust referral pathways to specialist centres that provide multidisciplinary care including performing SSRF.

BACKGROUND: The utilization of stereotactic body radiation therapy (SBRT) is increasing for primary and secondary lung neoplasms. Despite encouraging results, SBRT is associated with an increased risk of osteoradionecrosis-induced rib fracture. We aimed to (1) evaluate potential clinical, demographic, and procedure-related risk factors for rib fractures and (2) describe the radiographic features of post-SBRT rib fractures. METHODS: We retrospectively identified 106 patients who received SBRT between 2015 and 2018 for a primary or metastatic lung tumor with at least 12 months of follow up. Exclusion criteria were incomplete records, previous ipsilateral thoracic radiation, or relevant prior trauma. Computed tomography (CT) images were reviewed to identify and characterize rib fractures. Multivariate logistic regression modeling was employed to determine clinical, demographic, and procedural risk factors (e.g., age, sex, race, medical comorbidities, dosage, and tumor location). RESULTS: A total of 106 patients with 111 treated tumors met the inclusion criteria, 35 (32%) of whom developed at least one fractured rib (60 total fractured ribs). The highest number of fractured ribs per patient was five. Multivariate regression identified posterolateral tumor location as the only independent risk factor for rib fracture. On CT, fractures showed discontinuity between healing edges in 77% of affected patients. CONCLUSIONS: Nearly one third of patients receiving SBRT for lung tumors experienced rib fractures, 34% of whom experienced pain. Many patients developed multiple fractures. Post-SBRT fractures demonstrated a unique discontinuity between the healing edges of the rib, a distinct feature of post-SBRT rib fractures. The only independent predictor of rib fracture was tumor location along the posterolateral chest wall. Given its increasing frequency of use, describing the risk profile of SBRT is vital to ensure patient safety and adequately inform patient expectations.

BACKGROUND: The disadvantages and complications of computed tomography (CT) can be minimized if CT is performed in rib fracture patients with high probability of intra-thoracic and intra-abdominal injuries and CT is omitted in rib fracture patients with low probability of intra-thoracic and intra-abdominal injuries. This study aimed to evaluate the factors that can identify patients with rib fractures with intra-thoracic and intra-abdominal injuries in the emergency department among patients with rib fracture. METHODS: This retrospective observational study included adult patients (age ≥ 18 years) diagnosed with rib fracture on chest radiography prior to chest CT due to blunt chest trauma in the emergency department who underwent chest CT from January 2016 to February 2021. The primary outcomes were intra-thoracic and intra-abdominal injuries that could be identified on a chest CT. Multivariate logistic regression analysis was performed. RESULTS: Among the characteristics of rib fractures, the number of rib fractures was greater (5.0 [3.0-7.0] vs. 2.0 [1.0-3.0], p < 0.001), bilateral rib fractures were frequent (56 [20.1%] vs. 12 [9.8%], p = 0.018), and lateral and posterior rib fracture was more frequent (lateral rib fracture: 160 [57.3%] vs. 25 [20.5%], p < 0.001; posterior rib fracture: 129 [46.2%] vs. 21 [17.2%], p < 0.001), and displacement was more frequent (99 [35.5%] vs. 6 [6.6%], p < 0.001) in the group with intra-thoracic and intra-abdominal injuries than in the group with no injury. The number of rib fractures (adjusted odds ratio [aOR], 1.44; 95% confidence interval [CI], 1.16-1.78; p = 0.001), lateral rib fracture (aOR, 2.80; 95% CI, 1.32-5.95; p = 0.008), and posterior rib fracture (aOR, 3.18; 95% CI, 1.45-6.94; p = 0.004) were independently associated with intra-thoracic and intra-abdominal injuries. The optimal cut-off for the number of rib fractures on the outcome was three. The number of rib fractures ≥ 3 (aOR, 3.01; 95% CI, 1.35-6.71; p = 0.007) was independently associated with intra-thoracic and intra-abdominal injuries. CONCLUSION: In patients with rib fractures due to blunt trauma, those with lateral or posterior rib fractures, those with ≥ 3 rib fractures, and those requiring O2 supplementation require chest CT to identify significant intra-thoracic and intra-abdominal injuries in the emergency department.

Thoracic injuries are infrequent among children, but still represent one of the leading causes of pediatric mortality. Studies on pediatric chest trauma are dated, and little is known of outcomes in different age categories. This study aims to provide an overview of the incidence, injury patterns, and in-hospital outcomes of children with chest injuries. A nationwide retrospective cohort study was performed on children with chest injuries, using data from the Dutch Trauma Registry. All patients admitted to a Dutch hospital between January 2015 and December 2019, with an abbreviated injury scale score of the thorax between 2 and 6, or at least one rib fracture, were included. Incidence rates of chest injuries were calculated with demographic data from the Dutch Population Register. Injury patterns and in-hospital outcomes were assessed in children in four different age groups. A total of 66,751 children were admitted to a hospital in the Netherlands after a trauma between January 2015 and December 2019, of whom 733 (1.1%) sustained chest injuries accounting for an incidence rate of 4.9 per 100,000 person-years. The median age was 10.9 (interquartile range (IQR) 5.7-14.2) years and 62.6% were male. In a quarter of all children, the mechanisms were not further specified or unknown. Most prevalent injuries were lung contusions (40.5%) and rib fractures (27.6%). The median hospital length of stay was 3 (IQR 2-8) days, with 43.4% being admitted to the intensive care unit. The 30-day mortality rate was 6.8%. CONCLUSION: Pediatric chest trauma still results in substantial adverse outcomes, such as disability and mortality. Lung contusions may be inflicted without fracturing the ribs. This contrasting injury pattern compared to adults underlines the importance of evaluating children with chest injuries with additional caution. WHAT IS KNOWN: ⢠Chest injuries are rare among children, but represent one of the leading causes of pediatric mortality. ⢠Children show distinct injury patterns in which pulmonary contusions are more prevalent than rib fractures. WHAT IS NEW: ⢠The proportion of chest injuries among pediatric trauma patients is currently lower than reported in previous literature, but still leads to substantial adverse outcomes, such as disabilities and death. ⢠The incidence of rib fractures gradually increases with age and in particular around puberty when ossification of the ribs becomes completed. The incidence of rib fractures among infants is remarkably high, which is strongly suggestive for nonaccidental trauma.

BACKGROUND: Scapula fractures (SFs) occur as a result of high-energy trauma and are significant in terms of life-threatening injuries. There are few studies showing the relationship between SFs and mortality and morbidity in patients with blunt thoracic trauma (BTT). Our study aims to investigate the relationship between SF and mortality and morbidity in BTT. METHODS: Adult patients admitted to the emergency department of Kahramanmaras Sutcu Imam University, School of Medicine with BTT between January 2019 and April 2021 were retrospectively scanned from hospital records. Patients' age, gender, trauma mechanism, additional organ injuries, need for intensive care, length of hospital stay, morbidity, and mortality rates were recorded. Statistical results were expressed as frequency, percentage, and mean±standard deviation (min-max). In comparisons between groups, p<0.05 was accepted as the significance level. RESULTS: Two hundred and thirty-eight cases were included in our study. The scapular fracture was present in 86 cases (36.1%). About 43% of the cases with SFs were falling from a height. Intrathoracic injuries accompanying SF were determined as rib fracture, lung contusion, pneumothorax, hemothorax, and sternum fracture, respectively (91.9%, 80.2%, 41.9%, 37.2%, and 15.1%). Extrathoracic injuries associated with SF were vertebral fractures, intracranial injuries, clavicle fractures, extremity fractures, and intra-abdominal injuries (18.6%, 16.3%, 12.8%, 10.5%, and 5.8%), respectively. When the groups with and without SF were compared, a statistically significant relationship was found between SF and the number of rib fractures, lung contusion, pneumothorax, and hemothorax (p<0.001, p=0.001, p=0.001, p=0.001). In extrathoracic injuries, there was a significant relationship between SFs and vertebral fractures, intra-cranial injuries, and clavicle fractures (p=0.004, p<0.001, p=0.005). There was no difference observed between the groups regarding sternum fractures, extremity fractures, and intra-abdominal organ injuries (p=0.288, p=0.682, p=0.261). In cases with accompanying SF, there was a significant difference in terms of length of hospital stay, need for intensive care, and mortality (p<0.001, p=0.001, p=0.002). CONCLUSION: The most common intrathoracic injuries accompanying SFs were rib fractures and lung contusion, and the most common extrathoracic injuries were vertebral fractures and intracranial injuries. Moreover, it was found that SF was highly correlated with length of hospital stay, need for intensive care, and mortality. The most common cause of mortality was found to be intracranial hemorrhage. Imaging of other systems is important in cases with SFs. Particular attention should be paid to head-and-neck injuries.

INTRODUCTION: Sternal fractures (SF) are uncommon injuries usually associated with a significant mechanism of injury. Concomitant injury is likely, and a risk of mortality is substantial. AIM: Our aim in this study was to identify the risk factors for mortality in patients who had sustained sternal fractures. METHODS: We conducted a single centre retrospective review of the trust's Trauma Audit and Research Network Database, from May 2014 to July 2021. Our inclusion criteria were any patients who had sustained a sternal fracture. The regions of injury were defined using the Abbreviated Injury Score. Pearson Chi-Squared, Fisher Exact tests and multivariate regression analyses were performed using IBM SPSS. RESULTS: A total of 249 patients were identified to have sustained a SF. There were 19 patients (7.63%) who had died. The most common concomitant injuries with SF were Rib fractures (56%), Lung Contusions (31.15%) and Haemothorax (21.88%). There was a significant increase in age (59.93 vs 70.06, p = .037) and admission troponin (36.34 vs. 100.50, p = .003) in those who died. There was a significantly lower GCS in those who died (10.05 vs. 14.01, p < .001). On multi regression analysis, bilateral rib injury (p = 0.037, OR 1.104) was the only nominal variable which showed significance in mortality. CONCLUSION: Sternal Fractures are uncommon but serious injuries. Our review has identified that bilateral rib injuries, increase in age, low GCS, and high admission troponin in the context of SF, were associated with mortality.

PURPOSE: Spontaneous rib fracture (SRF) is a common late complication in treated breast cancer patients. This study evaluated the incidence and risk factors of ipsilateral SRF after radiotherapy (RT) in breast cancer patients. In addition, we identified dosimetric parameters that were significantly associated with ipsilateral SRF. METHODS: We retrospectively reviewed 2204 patients with breast cancer who underwent RT between 2014 and 2016, and were followed up with bone scans. We evaluated clinical risk factors for ipsilateral SRF. Dose-volume histogram analysis was also performed for patients (nâ¯= 538) whose dosimetric data were available. All ipsilateral ribs were manually delineated, and dosimetric parameters of the ribs were converted into the equivalent dose in 2â¯Gy fractions (EQD2). RESULTS: Most of the patients with SRF (87.3%) were asymptomatic, and the remaining symptomatic patients complained of mild tenderness or chest wall discomfort; these symptoms all resolved within 6 months without any treatment. Ipsilateral SRF occurred in 14.5% of patients 3 years after RT. The median time to develop ipsilateral SRF was 15 months. In dosimetric analysis, near-maximum rib dose (D2cc) best predicted ipsilateral SRF. The cut-off value of D2cc was EQD2 52â¯Gy, as determined by receiver operating characteristic analysis. In multivariate analysis including dosimetric variables, D2cc EQD2â¯≥ 52â¯Gy was the only significant risk factor for ipsilateral SRF. CONCLUSION: Our data demonstrated that near-maximum rib dose was the best dosimetric parameter to predict ipsilateral SRF in RT-treated breast cancer patients. In addition, our results suggest that patients who received RT with exceeding rib dose cut-off value and had ipsilateral SRF on bone scan be recommended routine follow-up without additional imaging tests.

BACKGROUND: A prior single-site study from the Midwest exploring seasonality of traumatic rib fractures found injuries are more common during summer months and lower in winter months. There have been no modern studies evaluating seasonality of these common injuries nationally. Our aim was to describe temporal and spatial distribution of rib fractures in the United States. We hypothesized presentations for traumatic rib fractures follow a seasonal pattern, with greater frequency of rib fractures in the summer and lower levels in the winter. METHODS: We obtained hospital emergency department (ED) encounter data from Nationwide Emergency Department Sample (NEDS) from January 1, 2018 to December 31, 2018. We used ICD-10 codes to identify all patients with diagnostic codes specific to rib fractures. To examine seasonal patterns, we constructed negative binomial regression models using seasons as covariates to predict incidence of rib fracture encounters across regions. RESULTS: Of 15,439,004 trauma-related ED encounters in 2018, 384 431 (2%) encounters included a diagnosis of rib fracture(s). The percentage of ED trauma encounters with rib fractures was similar across the 4 regions. Rib fractures were more common in the summer in the Midwest, South, and West as compared to winter [22% (95% CI = 10-34%, P = .007), 12% (95% CI = 5-20%, P = 0.02), and 11% (95% CI = 5-17%, P = .008), respectively]. DISCUSSION: Our hypothesis was generally supported by our evaluation of NEDS. However, while seasonal variation in rib fractures does appear to exist in the Midwest, South, and West, this variation is not ubiquitous across the United States.

BACKGROUND: Thoracic injuries are common among trauma patients. Studies on trauma patients with thoracic injuries have reported considerable differences in morbidity and mortality, and there is limited research on comparison between trauma patients with and without thoracic injuries, particularly in the Scandinavian population. Thoracic injuries in trauma patients should be identified early and need special attention since the differences in injury patterns among patient population are important as they entail different treatment regimens and influence patient outcomes. The aim of the study was to describe the epidemiology of trauma patients with and without thoracic injuries and its influence on 30-day mortality. METHODS: Patients were identified through the Karolinska Trauma Register. The Abbreviated Injury Scale (AIS) system was used to find patients with thoracic injuries. Logistic regression analysis was performed to evaluate factors [age, gender, ASA class, GCS (Glasgow Coma Scale), NISS (New Injury Severity Score) and thoracic injury] associated with 30-day mortality. RESULTS: A total of 2397 patients were included. Of those, 768 patients (32%) had a thoracic injury. The mean (± SD, range) age of all patients (n = 2397) was 46 (20, 18-98) years, and the majority (n = 1709, 71%) of the patients were males. There was a greater proportion of patients with rib fractures among older (≥ 60 years) patients, whereas younger patients had a higher proportion of injuries to the internal thoracic organs. The 30-day mortality was 11% (n = 87) in patients with thoracic injury and 4.3% (n = 71) in patients without. After multivariable adjustment, a thoracic injury was found to be associated with an increased risk of 30-day mortality (OR 1.9, 95% CI 1.3-3.0); as was age ≥ 60 years (OR 3.7, 95% CI 2.3-6.0), ASA class 3-4 (OR 2.3, 95% CI 1.4-3.6), GCS 1-8 (OR 21, 95% CI 13-33) and NISS > 15 (OR 4.2, 2.4-7.3). CONCLUSION: Thoracic injury was an independent predictor of 30-day mortality after adjustment for relevant key variables. We also found a difference in injury patterns with older patients having a higher proportion of rib fractures, whilst younger patients suffered more internal thoracic organ injuries.

INTRODUCTION: The number of older adults hospitalised for injury is growing rapidly. The population-adjusted incidence of isolated thoracic injuries in older adults is also growing. While some older adults are at high risk of post-traumatic complications, not all older adults will need treatment in a major trauma service (MTS). The aim of this study was to characterise older patients with isolated chest injuries, determine the rates of post-traumatic complications, including respiratory failure and pneumonia, and the factors associated with the risk of developing these complications. PATIENTS AND METHODS: This was a retrospective review of patients aged 65 years and over with isolated chest trauma, from January 2007 to June 2017, using data from the Victorian State Trauma Registry. Patient characteristics and rates of complications were compared between patients with 1. isolated rib fractures, and 2. complex chest injury. Multivariable logistic regression was used to identify predictors of respiratory failure, and pneumonia. RESULTS: The study population comprised 5401 patients aged 65 years or more, with isolated chest injuries. Two-thirds (65%) of all patients had isolated rib fractures, and 58% of patients (n = 3156) were directly admitted to a non-major trauma centre. Complications were uncommon, with 5.45% of all patients (n = 295) having pneumonia and 3.2% (n = 175) having respiratory failure. Factors associated with increased risk of pneumonia and respiratory failure included advancing age, smoking, chronic obstructive pulmonary disease, congestive heart failure, and more severe and complex chest injury. The adjusted odds of complications were lowest amongst patients not classified as major trauma and receiving definitive treatment in non-MTS. DISCUSSION: Our findings suggest that rates of complications in older patients with isolated chest trauma in this study were low, and that there is a large group of patients with isolated, uncomplicated rib fractures, who may not need to be treated in a major trauma centre. Further work should be undertaken to appropriately risk stratify and manage older adults with isolated chest trauma.

INTRODUCTION: Cardiopulmonary resuscitation (CPR)-related injuries have not been assessed since the 2015 Resuscitation Guidelines were established. AIM: To describe the incidence and severity of CPR-related injuries, and to evaluate the impact of the 2015 European Resuscitation Council (ERC) guidelines on the objective assessment of injuries. METHODS: This multicenter, retrospective study analyzed autopsy reports of patients who underwent CPR. The most severe injuries were objectively assessed using the Abbreviated Injury Scale (AIS) and all injuries were summarized according to the New Injury Severity Score (NISS). RESULTS: Among 628 autopsy reports analyzed, patient characteristics and case details were distributed as follows: male sex, 71.1%; median age, 67 years; out-of-hospital cardiac arrest, 89.2%; bystander CPR, 56.8%. CPR-related injuries included: rib(s) 94.6%; lung(s), 9.9%; sternum, 62.4%; liver, 2.5%; and spleen, 1.8%. The incidence of bystander-provided CPR and severity of injury were similar to CPR provided only by professionals. There were no difference between mechanical and manual compressions. Females were older (p = 0.0001) and, although the frequency of their injuries was similar to males, they were significantly more severe (p = 0.01). Patients with life-threatening injury exhibited a baseline profile similar to those without injury . The median score (according to AIS) of the most severe injury was 3 and the median of summary of injuries was 13 according to the NISS-low risk of fatal injury. CONCLUSION: CPR-related injuries occurred frequently, although those that were life-threatening accounted for only 3% of cases. There were no differences between patients who were resuscitated by bystander(s) or by professionals and no differences between mechanical chest devices or manual resuscitation. Compared with a study based on the 2010 guidelines, similar injuries were found, but with more rib fractures, less visceral organ damage, and fewer life-threatening injuries.

OBJECTIVE: The objective of this study is to generate age targeted versions of the male and female Global Human Body Models Consortium (GHBMC) occupant human body models (HBMs), to validate each in frontal impacts, and to assess rib fracture probability of each. METHODS: Six age targeted models were developed based on the GHBMC average male and small female occupant models (M50-O v6.0 and F05-O v6.0, respectively). All age targeted models were modified to represent population means for height, weight, shape, and relevant material properties. The thin plate spline method was used to morph models, and material properties were modified using available literature. Validation focused on chest response. Models were evaluated in a rigid body frontal chest impact at 6.7 m/s. Furthermore, the male and female age targeted models were evaluated against published data from 40 km/hr and 30 km/hr frontal sled tests respectively. RESULTS: Chest deflections and landmark kinematics reasonably matched the respective corridors in the M50-O and F05-O aged models. Regional probability of rib fracture was assessed using probabilistic methods based on cortex strain. Increasing rib fracture with age was observed in both impacts for both sexes. For the rigid chest impact, the M50-O 70YO resulted in 10 ribs exceeding 50% probability of fracture whereas the younger ages reported 4 to 6 ribs exceeding the same probability. In the same simulation, the F05-O 70YO resulted in 8 regions exceeding 50% probability of rib fracture as opposed to 3 and 0 such regions at the youngest ages. Sled simulation demonstrated similar trends. The 70YO age adjusted models best aligned with the reported extent of fractures from the referenced PMHS studies, which tend to be composed of subjects of advanced age. CONCLUSIONS: Age targeted HBMs demonstrated increased fracture probability with age when subjected to equivalent impacts. Gross model kinematics approximate PMHS data but showed little difference between targeted age models. The findings indicate that while gross kinematics are unaffected by age-targeting models, such models can capture trends of increased thoracic injury risk observed in experimental and field studies, and further suggest their potential use to target interventions for vulnerable driving populations, such as older adults.
