Large open chest wall wounds can be difficult to manage due to full-thickness tissue loss with underlying rib fractures and exposed lung parenchyma. Historically, the use of synthetic material has been discouraged in the traumatic setting with the concern that it may be associated with an increased risk of infection. We present 4 patients with large open injuries to the thorax-one from blunt and three from penetrating trauma. We describe our initial management followed by prompt surgical repair using biologic mesh, titanium rib spanning plates, and rotational tissue flaps with Z-plasty of the skin for definite closure. All patients did well post-operatively without complications or wound infections. With the appropriate management, we suspect there may be an advantage in performing immediate reconstruction and closure in large open thoracic injuries utilizing biologic mesh and titanium rib spanning plates with a lower risk of infection than previously believed., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Introduction: Sarcopenia has been shown to portend worse outcomes in injured patients; however, little is known about the impact of thoracic muscle wasting on outcomes of patients with chest wall injury. We hypothesized that reduced pectoralis muscle mass is associated with poor outcomes in patients with severe blunt chest wall injury., Methods: All patients admitted to the intensive care unit between 2014 and 2019 with blunt chest wall injury requiring mechanical ventilation were retrospectively identified. Blunt chest wall injury was defined as the presence of one or more rib fractures as a result of blunt injury mechanism. Exclusion criteria included lack of admission computed tomography imaging, penetrating trauma, <18 y of age, and primary neurologic injury. Thoracic musculature was assessed by measuring pectoralis muscle cross-sectional area (cm 2 ) that was obtained at the fourth thoracic vertebral level using Slice-O-Matic software. The area was then divided by the patient height in meters 2 to calculate pectoralis muscle index (PMI) (cm 2 /m 2 ). Patients were divided into two groups, 1) the lowest gender-specific quartile of PMI and 2) second-fourth gender-specific PMI quartiles for comparative analysis., Results: One hundred fifty-three patients met the inclusion criteria with a median (interquartile range) age 48 y (34-60), body mass index of 30.1 kg/m 2 (24.9-34.6), and rib score of 3.0 (2.0-4.0). Seventy-five percent of patients (116/153) were male. Fourteen patients (8%) had prior history of chronic lung disease. Median (IQR) intensive care unit length-of-stay and duration of mechanical ventilation (MV) was 18.0 d (13.0-25.0) and 15.0 d (10.0-21.0), respectively. Seventy-three patients (48%) underwent tracheostomy and nine patients (6%) expired during hospitalization. On multivariate linear regression, reduced pectoralis muscle mass was associated with increased MV duration when adjusting for rib score and injury severity score (β 5.98, 95% confidence interval 1.28-10.68, P = 0.013)., Conclusions: Reduced pectoralis muscle mass is associated with increased duration of MV in patients with severe blunt chest wall injury. Knowledge of this can help guide future research and risk stratification of critically ill chest wall injury patients., (Published by Elsevier Inc.)

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., Competing Interests: Declaration of competing interest The authors declare no competing interest., (Copyright © 2024 The Authors.

Blunt mechanism chest wall injury (CWI) is commonly seen in the emergency department (ED), since it is present in around 15% of trauma patients. The thoracic cage protects the heart, lungs and trachea, thereby supporting respiration and circulation, so injury to the thorax can induce potentially life-threatening complications. Systematic care pathways have been shown to improve outcomes for patients presenting with blunt mechanism CWI, but care is not consistent across the UK. Emergency nurses have a crucial role in assessing and treating patients who present to the ED with blunt mechanism CWI. This article discusses the initial assessment and acute care priorities for this patient group. It also presents a prognostic model for predicting the probability of in-hospital complications following blunt mechanism CWI., Competing Interests: None declared, (© 2024 RCN Publishing Company Ltd.

Purpose: Surgical stabilization of rib fractures (SSRF) improves outcomes in certain patient populations. The Chest Wall Injury Society (CWIS) began a new initiative to recognize centers who epitomize their mission as CWIS Collaborative Centers (CWIS-CC). We sought to describe incidence and epidemiology of SSRF at our institutions., Methods: A retrospective registry evaluation of all patients (age > 15 years) treated at international trauma centers from 1/1/20 to 7/30/2021 was performed. Variables included: age, gender, mechanism of injury, injury severity score, abbreviated injury severity score (AIS), emergency department disposition, length of stay, presence of rib/sternal fractures, and surgical stabilization of rib/sternal fractures. Classification and regression tree analysis (CART) was used for analysis., Results: Data were collected from 9 centers, 26,084 patient encounters. Rib fractures were present in 24% (n = 6294). Overall, 2% of all patients underwent SSRF and 8% of patients with rib fractures underwent SSRF. CART analysis of SSRF by AIS-Chest demonstrated a difference in management by age group. AIS-Chest 3 had an SSRF rate of 3.7, 7.3, and 12.9% based on the age ranges (16-19; 80-110), (20-49; 70-79), and (50-69), respectively (p = 0.003). AIS-Chest > 3 demonstrated an SSRF rate of 9.6, 23.3, and 39.3% for age ranges (16-39; 90-99), (40-49; 80-89), and (50-79), respectively (p = 0.001)., Conclusion: Anticipated rate of SSRF can be calculated based on number of rib fractures, AIS-Chest, and age. The disproportionate rate of SSRF in patients age 50-69 with AIS-Chest 3 and age 50-79 with AIS-Chest > 3 should be further investigated, as lower frequency of SSRF in the other age ranges may lead to care inequalities., (© 2023.

Abstract: Blunt injuries to the chest wall, specifically those related to rib fractures, need to be promptly identified and effectively managed to reduce patient morbidity and mortality. Furthermore, judicious use of multimodal pain management and early identification of patients who will benefit from the surgical stabilization of rib fractures are paramount to optimal outcomes., (Copyright © 2022 American Academy of Physician Associates.)

Background: Blunt thoracic trauma is responsible for 35% of trauma-related deaths in the United States and significantly contributes to morbidity and healthcare-related financial strain. The goal of this study was to evaluate factors influencing mortality in patients emergently admitted with the primary diagnosis of blunt chest wall trauma. Methods: Adults emergently admitted for blunt chest trauma were assessed using the National Inpatient Sample Database, 2004-2014. Data regarding demographics, comorbidities, and outcomes were collected. Relationships were determined using univariable and multivariable logistic regression models. Results: In total, 1120 adult and 1038 elderly patients emergently admitted with blunt chest trauma were assessed; 46.3% were female, and 53.6% were male. The average ages of adult and elderly patients were 46.6 and 78.9 years, respectively. Elderly and adult patients both displayed mortality rates of 1%. The regression model showed HLOS and several comorbidities as the main risk factors of mortality Every additional day of hospitalization increased the odds of mortality by 9% (OR = 1.09, 95% CI = 1.01-1.18, p = 0.033). Mortality and liver disease were significantly associated (OR = 8.36, 95% CI = 2.23-31.37, p = 0.002). Respiratory disease and mortality rates demonstrated robust correlations (OR = 7.46, 95% CI = 1.63-34.11, p = 0.010). Trauma, burns, and poisons were associated with increased mortality (OR = 3.72, 95% CI = 1.18-11.71, p = 0.025). The presence of platelet/white blood cell disease correlated to higher mortality. (OR = 4.42, 95% CI = 1.09-17.91, p = 0.038).

Background: To improve care for nonintubated blunt chest wall injury patients, our Level I trauma center developed a treatment protocol and a pulmonary evaluation tool named "PIC Protocol" and "PIC Score," emphasizing continual assessment of pain, incentive spirometry, and cough ability., Objective: The primary objective was to reduce unplanned intensive care unit admissions for blunt chest wall injury patients using the PIC Protocol and the PIC Score. Additional outcomes included intensive care unit length of stay, ventilator days, length of hospital stay, inhospital mortality, and discharge destination., Methods: This was a retrospective cohort study comparing outcomes of rib fracture patients treated at our facility 2 years prior to (control group) and 2 years following PIC Protocol use (PIC group). The protocol included admission screening, a power plan order set, the PIC Score patient assessment tool, in-room communication board, and patient education brochure. Outcomes were compared using independent-samples t tests for continuous variables and Pearson's χ2 for categorical variables with α set to p < .05., Results: There were 1,036 patients in the study (control = 501; PIC = 535). Demographics and injury severity were similar between groups. Unanticipated escalations of care for acute pulmonary distress were reduced from 3% (15/501) in the control group to 0.37% (2/535) in the PIC group and were predicted by a preceding fall in the PIC Score of 3 points over the previous 8-hr shift, marking pulmonary decline by an acutely falling PIC Score., Conclusions: The PIC Protocol and the PIC Score are easy-to-use, cost-effective tools for guiding care of blunt chest wall injury patients., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2021 Society of Trauma Nurses.)

Background: The aim was to complete a feasibility study that would test the methods of the main trial, that will investigate whether early thoracic and shoulder girdle exercises reduce chronic pain in patients with blunt chest wall trauma, when compared with normal care., Methods: A single centre, parallel, feasibility randomised controlled trial was completed at a University Teaching Hospital in Wales between June and September 2019. Adult patients with blunt chest wall trauma, admitted to hospital for greater than 24 hours, with no concurrent, immediately life-threatening injuries, were included. The intervention was a simple physiotherapy programme comprising thoracic and shoulder girdle exercises. Feasibility outcome measures included: primary outcomes: (1) 80% or more of identified eligible patients were approached for potential recruitment to the trial (2) 30% or less of approached, eligible patients dissented to participate in the trial; secondary outcomes: (3) follow-up data for patient secondary outcomes can be collected for 80% or more of patients, (4) there should be no greater than 10% increase in serious adverse events in the intervention group compared with the control group., Results: A total of 19/19 (100%) patients were deemed eligible for the trial and were approached for participation, 5/19 (26%) eligible patients declined to participate in the trial, follow-up data were collected for n=10/14 (71%) patients and there were no serious adverse events reported in either group., Conclusions: We have demonstrated that a fully powered randomised clinical trial of the EarLy Exercise in blunt Chest wall Trauma Trial is feasible., Trial Registration Number: ISRCTN16197429., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021.

Traumatic thoracic or chest wall hernias are relatively uncommon but highly challenging injuries that can be seen after a variety of injury mechanisms. Despite their description throughout history there remains scant literature on this topic that is primarily limited to case reports or series. Until recently, there also has been no effort to create a reliable grading system that can assess severity, predict outcomes, and guide the choice of surgical repair. The purpose of this article is to review the reported literature on this topic and to analyze the history, common injury mechanisms, likely presentations, and optimal management strategies to guide clinicians who are faced with these challenging cases. We also report a modified and updated version of our previously developed grading system for traumatic chest wall hernias that can be utilized to guide surgical management techniques and approaches., Competing Interests: Declaration of competing Interest The authors report no proprietary or commercial interest in any product mentioned or concept discussed in this article.

Introduction: Trauma to the chest wall is one of the most common injuries suffered. Knowing whether there are regular and reproducible changes in frequency or severity of certain injury types may help resource allocation and improve prevention efforts or outcomes; however, no prior studies have evaluated seasonal variation in chest wall injuries (CWIs). We aimed to determine if CWIs vary annually in a consistent distinct temporal variation., Methods: Using an established traumatic blunt CWI database at a single urban level 1 trauma center, patients with a moderate-to-severe (chest wall Abbreviated Injury Score (AIS) ≥2) CWI were reviewed. A subpopulation of predominant chest wall injury (pCWI) was defined as those with a chest wall AIS ≥3 and no other anatomic region having a higher AIS. Demographics, injury patterns, mechanisms of injury, and AIS were collected in addition to date of injury over a 4-y period. Data were analyzed using descriptive statistics as well as Poisson time-series regression for periodicity. Seasonal comparison of populations was performed using Student's t-tests and Analysis of Variance (ANOVA) with significance assessed at a level of P < 0.05., Results: Over a 4-y period nearly 16,000 patients presented with injury, of which 3042 patients were found to have a blunt CWI. Total CWI patients per year from 2014 to 2017 ranged from 571 to 947. Over this period, August had the highest incidence for patients with any CWI, moderate-to-severe injuries, and pCWI. February had the lowest overall injury incidence as well as lowest moderate-to-severe injury incidence. January had the lowest pCWI incidence. Yearly changes followed a quadratic sinusoid model that predicted a peak between incidence, between June and October, and the low season. A low season was found to be December-April. Comparing low to high seasons of injured patient monthly means revealed significant differences: total injuries (69.94 versus 85.56, P = 0.04), moderate to severe (62.25 versus 78.19, P = 0.06), and pCWI (25.25 versus 34.44, P = 0.01). Analysis of injuries by mechanism revealed a concomitant increase in motorcycle collisions during this period., Conclusions: There appears to be a significant seasonal variation in the overall incidence of CWI as well as severe pCWI, with a high-volume injury season in summer months (June-October) and low-volume season in winter (December-April). Motorcycle accidents were the major blunt injury mechanism that changed with this seasonality. These findings may help guide resource utilization and injury prevention., (Copyright © 2020 Elsevier Inc. All rights reserved.)

Background: Circumferential burn of chest (CBC) is a significant type of burn and considers as a major cause of restrictive lung disease (RLD). Patient who has CBC with RLD leads to respiratory symptoms such as breathing difficulty, airway obstruction, reduced exercise capacity and altered pulmonary functions. However, studies examining the role of pranayama breathing exercise on pulmonary function, respiratory muscle activity and exercise tolerance in full thickness circumferential burn of chest are lacking., Objective: To find the short term effects of pranayama breathing exercise on pulmonary function, respiratory muscle activity and exercise tolerance in full thickness circumferential burns of chest., Methods: Through simple random sampling method thirty subjects (N = 30) with RLD following CBC were allocated to pranayama breathing exercise group (PBE-G; n = 15) and conventional breathing exercise group (CBE-G; n = 15). They received pranayama breathing exercise and conventional breathing exercise for 4 weeks respectively. All the subjects received chest mobility exercise as common treatment. Primary (Numeric Pain Rating Scale - NPRS, forced expiratory volume (FEV1), forced vital capacity (FVC) and maximum voluntary ventilation (MVV) and secondary (Electromyogram of sternocleidomastoid, scalene, external intercostal and diaphragm muscle, 6 min walk test & Global Rating of Change - GRC) outcome measures were measured at baseline, after four weeks and after three months follow up., Results: Baseline demographic and clinical variables show homogenous distribution between the groups (p > 0.05). Four weeks following different breathing exercises, PBE-G group shows more significant changes in pain intensity, pulmonary function, respiratory muscle activity, exercise tolerance and global rating of change than CBE-G group (p ≤ 0.05) at four weeks and three months follow up., Conclusion: Both groups showed improvement over time. However, differences between the groups were noticed small. Still physiotherapy management, which included pranayama breathing exercises with chest mobilization program, had an effective strategy in the treatment of restrictive lung disease following circumferential burn of chest., (Copyright © 2020 Elsevier Ltd and ISBI.

Aim: To report the epidemiology of injury and illness in elite rowers over eight seasons (two Olympiads)., Methods: All athletes selected to the Australian Rowing Team between 2009 and 2016 were monitored prospectively under surveillance for injury and illness. The incidence and burden of injury and illness were calculated per 1000 athlete days (ADs). The body area, mechanism and type of all injuries were recorded and followed until the resumption of full training. We used interrupted time series analyses to examine the association between fixed and dynamic ergometer testing on rowers' injury rates. Time lost from illness was also recorded., Results: All 153 rowers selected over eight seasons were observed for 48 611 AD. 270 injuries occurred with an incidence of 4.1-6.4 injuries per 1000 AD. Training days lost totalled 4522 (9.2% AD). The most frequent area injured was the lumbar region (84 cases, 1.7% AD) but the greatest burden was from chest wall injuries (64 cases, 2.6% AD.) Overuse injuries (n=224, 83%) were more frequent than acute injuries (n=42, 15%). The most common activity at the time of injury was on-water rowing training (n=191, 68). Female rowers were at 1.4 times the relative risk of chest wall injuries than male rowers; they had half the relative risk of lumbar injuries of male rowers. The implementation of a dynamic ergometers testing policy (Concept II on sliders) was positively associated with a lower incidence and burden of low back injury compared with fixed ergometers (Concept II). Illness accounted for the greatest number of case presentations (128, 32.2% cases, 1.2% AD)., Conclusions: Chest wall and lumbar injuries caused training time loss. Policy decisions regarding ergometer testing modality were associated with lumbar injury rates. As in many sports, illness burden has been under-recognised in elite Australian rowers., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2020.

Background: Nonintubated video-assisted thoracoscopic surgery has been widely reported in the past decade, while nonintubated chest wall stabilization has not been reported previously. The aim of this study was to evaluate the safety and feasibility of nonintubated minimally invasive chest wall stabilization in patients with multiple rib fractures., Methods: We conducted a prospective, single-arm, observational study. In this prospective study, 20 consecutive patients with multiple rib fractures were treated using nonintubated minimally invasive chest wall stabilization., Results: Minimally invasive chest wall stabilization was mostly performed for lateral rib fractures in this study (n = 8). The mean operation time was 92.5 min, and the mean blood loss was 49 ml. No patient required conversion to tracheal intubation. The mean extubation time of the laryngeal mask was 8.9 min; the mean postoperative fasting time was 6.1 h; the mean postoperative hospital stay was 6.2 days; the mean amount of postoperative drainage was 97.5 ml; the mean postoperative pain score was 2.9 points at 6 h, 2.8 points at 12 h, and 3.0 points at 24 h; and the mean postoperative nausea and vomiting score was 1.9 points at 6 h, 1.8 points at 12 h, and 1.7 points at 24 h., Conclusions: Nonintubated minimally invasive chest wall stabilization is safe and feasible in carefully selected patients. Further studies with a large sample size are warranted., Trial Registration: ChiCTR1900025698 . Registered on 5 September 2019.

Physical traumas are tragic and multifaceted injuries that suddenly threaten life. Although it is the third most common cause of death in all age groups, one out of four trauma patients die due to thoracic injury or its complications. Blunt injuries constitute the majority of chest trauma. This indicates the importance of chest trauma among all traumas. Blunt chest trauma is usually caused by motor vehicle accident, falling from height, blunt instrument injury and physical assault. As a result of chest trauma, many injuries may occur, such as pulmonary injuries, and these require urgent intervention. Chest wall and pulmonary injuries range from rib fractures to flail chest, pneumothorax to hemothorax and pulmonary contusion to tracheobronchial injuries. Following these injuries, patients may present with a simple dyspnea or even respiratory arrest. For such patient, it is important to understand the treatment logic and to take a multidisciplinary approach to treat the pulmonary and chest wall injuries. This is because only 10% of thoracic trauma patients require surgical operation and the remaining 90% can be treated with simple methods such as appropriate airway, oxygen support, maneuvers, volume support and tube thoracostomy. Adequate pain control in chest trauma is sometimes the most basic and best treatment. With definite diagnosis, the morbidity and mortality can be significantly reduced by simple treatment methods., (Copyright © 2020 Chinese Medical Association. Production and hosting by Elsevier B.V.

Background: In recent years, researchers and clinicians have been developing prognostic prediction tools (PPTs) as a way of identifying patients at risk of deterioration. The use of PPTs in the clinical environment not only impacts the risk of adverse outcomes for patients, but the use of these tools also effect clinical practice. Much attention has been paid to the clinical performance of PPTs. But more insight is needed on how the use of PPTs impacts clinical practice. The objective of this study was to map some of the ways in which PPTs effect clinical practice. The STUMBL (STUdy evaluating the impact of a prognostic model for Management of BLunt chest wall trauma patients) feasibility trial evaluated the use of a new prognostic prediction tool (PPT) to guide the management blunt chest wall trauma patients in the emergency departments (ED). The trial was undertaken between October 2016 and September 2018 and conducted at four sites in England and Wales. Nested within the feasibility trial was a qualitative study aimed at understanding how ED clinicians experienced and used the PPT. The qualitative methods included a focus group and telephone interviews with 9 ED clinicians. This study focused on participant perceptions of the feasibility and use of the STUMBL tool on clinical practice in the ED., Results: Clinical practice is reshaped as a result of the introduction of the STUMBL PPT into the clinical environment. The PPT enhanced reflexive awareness of prognostic practice; facilitated communication between patients and professionals; helps to guide patient outcomes; and provides a common ground for clinician discussion on prognostication., Conclusions: The qualitative data collected offered useful insights into the ways in which the tool changes clinical practice. This was a small study of the effect of one kind of PPT on clinical practice. Nevertheless, this study maps areas in which clinical practice is affected by the introduction of a PPT into the clinical environment. More research is needed to better understand these effects, and to understand how these tools become embedded in clinical practice over the longer term.

Objectives: Postoperative changes in pulmonary function (PF) and morphology due to surgical chest wall damage by thoracotomy with rib resection are unclear. Therefore, we evaluated the effects of surgical damage on PF and morphology at > 6 months postoperatively by comparing different lung lobectomy approaches., Methods: A total of 140 patients who underwent lobectomy for lung diseases between January 2006 and March 2016 were analyzed. Patients who underwent PF tests and computed tomography (CT) scans preoperatively and postoperatively were divided into posterolateral thoracotomy with one rib resection (PT) group and video-assisted thoracoscopic surgery (VATS) group. A 1:1 propensity score-matched (PSM) analysis was used to balance clinically important confounders between the groups. Regarding morphology, lung volume was measured semi-automatically using image analysis software and reconstructed three-dimensional (3D) images., Results: After PSM, 31 patients in each group were compared. Perioperative reduction ratios in forced vital capacity (FVC) (- 23% vs. - 13%; P = 0.006) and forced expiratory volume in 1 s (FEV1) (- 19% vs. - 12%; P = 0.02) were significantly larger for the PT group. No significant differences in lung volume values based on 3D CT volumetry (PT vs. VATS; total lung volume: - 7.9% vs. - 7.2%, P = 0.82; non-resected ipsilateral lung volume: + 36% vs. + 40%, P = 0.69; contralateral lung volume: + 9.3% vs. + 9.4%, P = 0.98) were found in either group., Conclusions: Among the patients underwent lobectomy, classic thoracotomy decreased PF by an additional FVC loss of 10% and FEV1 loss of 7% compared with VATS, without affecting residual lung volume.

Introduction: A patient-relevant, focused Core Outcome Set (COS) is essential to the design of clinical trials dealing with chest wall trauma, in order to maximise quality of evidence regarding impact of interventions and to reduce research waste., Methods: Outcome measures were collated by way of systematic review and entered into a three round Delphi consensus completed anonymously online. Participants were international clinicians and allied health professionals (AHP) involved in the treatment of rib fractures as well as patients who had experienced severe chest trauma. Consensus thresholds for statements were defined a priori as a group rating of more than 70% or less than 15% for 'important' or 'not important'., Results: Sixty-five participants responded to the first round and the final round Final round consisted of five AHP, two patients and 16 clinicians from eight different countries. Twenty-three outcomes were regarded as important for the COS; eight adverse events, three mortality, five clinical or physiological outcomes, six life impact and one resource-related. Health related quality of life was rated highest of the life impact outcomes but participants thought it was also important to assess disability, physical function, quality of life, return to activities and return to work., Conclusion: Collecting serious adverse outcomes was important to all stakeholders as were life impact outcomes such as quality of life, physical function and return to activities. Resource use outcomes were considered less important. We recommend this Core Outcome Set, developed with multiple relevant stakeholders, for use in future clinical trials, following further work on the most appropriate methods and instruments for measurement., Competing Interests: Declaration of Competing Interest AR declares receiving research and educational grants from DePuy Ltd outside the submitted work.

Most diaphragmatic ruptures are due to the traumatic or penetrating injury, while the spontaneous diaphragmatic rupture is considered uncommon. The spontaneous transdiaphragmatic hernia is a consequence of violent coughing, vomiting that increase the thoracoabdominal pressure causing the diaphragmatic rupture. Even rarer is the concomitant prolapse of abdominal viscera into the thoracic subcutis through the chest wall, a condition known as spontaneous transdiaphragmatic intercostal hernia. Herein, we present a rare case of spontaneous transdiaphragmatic intercostal hernia presenting as a thoracoabdominal emergency.

Trauma affecting the chest wall, even in isolation, can carry a significant morbidity and mortality and thus appropriate management is vital. Consequences of chest wall trauma may include significant pain, altered chest wall mechanics, hypoventilation, infection and respiratory failure. In order to best determine the appropriate management, risk stratification tools have been developed to identify patients at highest risk of complications who would most benefit from more invasive management strategies. Early optimization of analgesia is vital both for patient experience and to reduce the risk of pulmonary complications. The analgesic options range from multimodal oral analgesia to invasive regional anaesthetic techniques such as thoracic epidurals, paravertebral catheters, intercostal nerve blocks and fascial plane blocks. Other important considerations include provision of appropriate oxygen therapy, ventilation support and physiotherapy. For a selected group of patients with the most significant injuries, surgical rib fixation may be appropriate if chest wall mechanics are sufficiently impaired.

Thoracic and thoraco-abdominal aortic repair remains a challenging issue in vascular surgery, and long-term complications are well described. We report 2 cases of octogenarians with unusual long-term complications after open and endovascular thoracic aortic repair of chest wall pressure injury from the vascular prosthesis. In the first case, a computed tomographic scan of an 80-year-old man showed a pressure injury of the chest wall and rib erosion caused by a Dacron graft. The second case was an 81-year-old woman who presented with external bleeding from the left posterior chest wall. A computed tomographic scan showed a type IA endoleak and chest wall damage with rib erosion and thoracic cutaneous fistulae from the endovascular graft. Both patients were treated by relining the endovascular graft; debriding the surgical fistula was done only in the second case. In our experience, endovascular repair is a good option to avoid a complete open surgical repair., (© The Author(s) 2019.

Tricuspid valve (TV) avulsion is rare and ordinarily does not require emergent intervention. We present the case of a polytrauma patient with traumatic TV avulsion who ultimately required urgent TV replacement in the setting of hemodynamic instability. Urgent TV replacement may be warranted after careful consideration of patient risk factors and clinical context.

Objectives: Taxonomy of injuries involving the costal margin is poorly described and surgical management varies. These injuries, though commonly caused by trauma, may also occur spontaneously, in association with coughing or sneezing, and can be severe. Our goal was to describe our experience using sequential segmental analysis of computed tomographic (CT) scans to perform accurate assessment of injuries around the costal margin. We propose a unifying classification for transdiaphragmatic intercostal hernia and other injuries involving the costal margin. We identify the essential components and favoured techniques of surgical repair., Methods: Patients presenting with injuries to the diaphragm or to the costal margin or with chest wall herniation were included in the study. We performed sequential segmental analysis of CT scans, assessing individual injury patterns to the costal margin, diaphragm and intercostal muscles, to create 7 distinct logical categories of injuries. Management was tailored to each category, adapted to the individual case when required. Patients with simple traumatic diaphragmatic rupture were considered separately, to allow an estimation of the relative incidence of injuries to the costal margin compared to those of the diaphragm alone., Results: We identified 38 patients. Of these, 19 had injuries involving the costal margin and/or intercostal muscles (group 1). Sixteen patients in group 1 underwent surgery, 2 of whom had undergone prior surgery, with 4 requiring a novel double-layer mesh technique. Nineteen patients (group 2) with diaphragmatic rupture alone had a standard repair., Conclusions: Sequential analysis of CT scans of the costal margin, diaphragm and intercostal muscles defines accurately the categories of injury. We propose a 'Sheffield classification' in order to guide the clinical team to the most appropriate surgical repair. A variety of surgical techniques may be required, including a single- or double-layer mesh reinforcement and plate and screw fixation., (© The Author(s) 2019.

Background: Rib fractures are common in ageing people after trauma and delirium is a complication often seen in acutely hospitalized elderly patients. For both conditions, elderly have an increased risk for institutionalization, morbidity, and mortality. This study is the first to investigate risk factors of delirium in elderly patients with rib fractures after trauma., Methods: A retrospective chart review was performed on patients ≥65 years admitted with rib fractures after blunt chest wall trauma to the Amphia hospital Breda, the Netherlands, between July 2013 and June 2018. Baseline patient, trauma- and treatment-related characteristics were identified. The main objectives were identification of risk factors of delirium and investigation of the effect of delirium on outcomes after rib fractures. Outcomes were additional complications, length of hospital stay, need for institutionalization and mortality within six months., Results: Forty-seven (24.6%) of 191 patients developed a delirium. Independent risk factors for delirium were increased age, physical impairment (lower KATZ-ADL score), nutritional impairment (higher SNAQ score) and the need for a urinary catheter, with odds ratios of 1.07, 0.78, 1.53 and 8.53 respectively. Overall, more complications were observed in patients with delirium. Median ICU and hospital length of stay were 4 and 7 days respectively, of which the latter was significantly longer for delirious patients (p < 0.001). Significantly more patients with delirium were discharged to a nursing home or rehabilitation institution (p < 0.001). The 6-month mortality in delirious patients was nearly twice as high as in non-delirious patients; however, differences did not reach statistical significance., Conclusion: Delirium in elderly patients with rib fractures is a serious and common complication, with a longer hospital stay and a higher risk of institutionalization as a consequence. Increased awareness for delirium is imperative, most importantly in older patients, in physically or nutritionally impaired patients and in patients in need of a urinary catheter.

Background: Extensive burn scars and contractures are likely to restrict the movements of the chest wall which may affect the pulmonary ventilation by restricting its expansion during inspiration. We designed this study to evaluate the effect of burn contractures of chest wall on pulmonary function and to estimate the effect of contracture release on pulmonary functions in patients with compromised PFT., Methods: Pulmonary function tests (PFT) of 20 patients having chest wall contractures involving more than 50% of the chest circumference were studied. Restrictive lung disease was defined as forced vital capacity (FVC) value less than 80% of predicted normal for the age, weight, and height of that patient. Patients with a restrictive pattern on PFT were subjected to the surgical release of the contracture. PFT was repeated one month after the surgery which was compared with the initial report., Results: Of the 20 patients included in the study, 5 (25%) patients had a restriction pattern on PFT. 1 patient had a mild restriction, 2 patients had moderate restriction and 2 patients had a severe restriction of pulmonary function. The mean duration of contracture was 58.2±15.75months in patients with a pulmonary restriction as compared to 29.87±6.21months in patients with a normal PFT (p=0.001). All patients having a restrictive pattern on PFT had contracture involvement of >75% of the chest wall circumference (p=0.0036). The mean forced vital capacity (FVC) increased from 1.94L preoperatively to 2.11L after surgical release of the contracture (p=0.047). However, the restriction pattern in PFT did remain., Conclusion: Long standing chest wall contractures and contractures involving >75% of the chest circumference are likely to cause a restrictive pattern on PFT. Any significant improvement of pulmonary function after surgical release of the contracture is unlikely., (Copyright © 2018 Elsevier Ltd and ISBI. All rights reserved.)

Background: Conservative treatment of even severe thoracic trauma including flail chest was traditionally the standard of care. Recently, we reported possible benefits of surgical chest wall stabilization in accordance with other groups. The aim of this study was to critically review our indications and results of internal fixation of rib fractures in the long-term course., Methods: We retrospectively analyzed the data of a consecutive series of patients with internal rib fracture fixation at our institution from 8/2009 until 12/2014, and we retrospectively studied the late outcome through clinical examination or personal interview., Results: From 1398 patients, 235 sustained a severe thoracic trauma (AIS ≥3). In 23 of these patients, 88 internal rib fixations were performed using the MatrixRIB ® system. The median age of these operated patients was 56 years [interquartile range (IQR) 49-63] with a median ISS of 21 [IQR 16-29]. From 18 local resident patients, follow-up was obtained after an average time period of 27.6 (12-68) months. Most of these patients were free of pain and had no limitations in their daily routine. Out of all implants, 5 splint tips perforated the ribs in the postoperative course, but all patients remained clinically asymptomatic. Plate osteosynthesis showed no loss of reduction in the postoperative course. No cases of hardware prominence, wound infection or non-union occurred., Conclusions: In our carefully selected thoracic trauma patients, locked plate rib fixation seemed to be safe and beneficial not only in the early posttraumatic course, but also after months and years, patients remain asymptomatic and complete recovery as a rule.

Tubercular infection of the chest wall is rare and typically progresses to abscess formation. Treatment of these abscesses combines medical therapy with surgical debridement, which can cause defects of various sizes. This case report describes reconstruction of relatively small chest wall defects caused by tubercular abscesses with the use of two different flaps: a lateral intercostal artery perforator flap and a split pectoralis major muscle flap. The use of these flap techniques may provide a novel approach to cover small chest wall defects caused by tubercular abscesses., (Copyright © 2018 The Society of Thoracic Surgeons.

Background: Fractures of the anterior chest wall are rare among the total number of fractures. They include sternal fractures (SF) and the adjacent cartilaginous structures of the ribs. The accident mechanism can allow conclusions to be drawn about which further accompanying injuries may be present, e.g. rib and spinal fractures., Objective: The present work is intended to give an overview of injuries of the anterior chest wall. It includes clinical aspects as well as imaging and popular literature., Material and Methods: Included are injury constellations of the anterolateral chest wall, in particular of the sternum in combination with injuries of the spinal column in the sense of a sternovertebral injury (SVI). Possible treatment strategies were reviewed and the corresponding advantages and disadvantages are presented., Results: In symptomatic fractures of the anterior chest wall, their operative stabilization should be considered in order to restore the stability of the trunk. In addition, rib fractures in direct trauma and spinal injuries in indirect trauma are often included in the treatment., Conclusion: In the case of injuries of the thoracic trunk, this must always be regarded as a unit and must therefore be clarified in the context of the clinical examination and diagnostic apparatus. The possible accident mechanism can allow conclusions to be drawn about possible injury patterns, e.g. in the sense of SVIs.

Background: Fractures of the bony chest wall are common injuries. They affect almost every second severely injured person and are gaining more and more importance even after low-energy accidents, especially among older people. Complications mainly occur due to respiratory insufficiency, secondary pulmonary complications and remaining deformities with a functional disorder of the chest wall. In addition to the important conservative therapeutic measures, such as a differentiated pain therapy and pneumonia prophylaxis, operative stabilization of fractures can be an option; however, this is still controversially discussed., Objective: A thematically structured overview provides basic knowledge on rib and sternal fractures as well as the treatment options., Material and Methods: Epidemiological facts are presented based on the relevant literature and clinical experience. Anatomical principles are intended to improve understanding of the various entities of rib and sternal fractures. For this purpose, the new AO‑/OTA classification system is presented and finally therapeutic options including different osteosynthesis procedures are presented and their importance discussed., Results and Discussion: Multimodal therapy concepts and closely controlled follow-up examinations of fractures avoid complications or can detect them early. Bony chest wall injuries should still be evaluated for complications and typical fracture patterns identified and classified. Modern osteosynthesis procedures with high patient safety and soft tissue-preserving tissue preparation for the surgical access route to the ribs and sternum provide an excellent opportunity for successful restoration of the anatomical and physiological integrity of the bony thorax.

Background: Flail chest wall injuries (FCI) are common in younger patients due to high-speed trauma and in older patients due to low-energy trauma or falls from a low height. They show a high incidence of concomitant injuries and are therefore associated with high morbidity and mortality. If there is also an ipsilateral clavicular fracture (CF), the outcome is significantly poorer. The skeleton of the shoulder and chest loses stability and can lead to a loss of function of the shoulder and a pronounced deformation of the chest wall., Objective: This article shows the origin and clinical importance of FCI. What importance does a concomitant ipsilateral CF have and how can these costoclavicular injuries (CCI) be managed conservatively and operatively?, Material and Methods: After primary emergency care of the patients with appropriate diagnostics, in the presence of CCI operative stabilization was carried out by means of locked plate osteosynthesis of the clavicle and the affected ribs via minimally invasive approaches with the patient under general anesthesia. Patients were followed up postoperatively. Various minimally invasive posterolateral approaches to the chest wall were previously performed in a corpse study and then put into practice., Results and Conclusion: This study presents therapeutic options for the reconstruction of the chest wall based on the established literature and clinical examples. An ipsilateral CF combined with fractures of the 2nd-4th ribs can be treated through an innovative clavipectoral approach. For the other fractures, standard approaches to the anterolateral and posterolateral chest wall are performed, which are associated with a good outcome in clinical practice. An operative stabilization should be performed at the latest when FCI or CCI together with a dislocating fracture and a marked deformation of the thoracic wall are present. Remaining misalignments are associated with a simultaneous loss of function of the chest wall and shoulder.

Background: This study aimed to assess the outcome of patients undergoing internal fixation of complex rib fractures in a U.K. major trauma center., Methods: A retrospective analysis was performed on all patients undergoing operative fixation of rib fractures from March 2014 to May 2016. Outcome measures included hospital length of stay, intensive care unit (ICU) admission, mechanical ventilation, infection, and mortality., Results: One hundred and two patients (66 male patients and 36 female patients, with a median age of 62 years) underwent rib fracture fixation during the study period. The causes of trauma were road traffic accidents in 39 patients (38%), a fall from a substantial height in 38 patients (37%), and a fall down stairs in 21 patients (21%). Thirty-eight patients (37%) had isolated chest trauma, and 64 patients (63%) had additional injuries. Fifty-three patients (52%) required ICU admission with a mean ICU stay of 4.7 days (range, 1 to 34 days). The median hospital length of stay was 10.6 days (range, 3 to 51 days). Patients with additional injuries (p = 0.01) and those requiring mechanical ventilation (p < 0.0001) stayed significantly longer. Sixty-five patients (64%) underwent rib fixation within 48 hours of the injury, and 37 patients (36%) underwent the surgical procedure after 48 hours. A surgical procedure within 48 hours resulted in a shorter ICU stay (p = 0.01), fewer cases of pneumonia (p = 0.001), reduced duration of mechanical ventilation (p = 0.03) and fewer tracheostomies (p = 0.02), and shorter hospital length of stay (11.5 compared with 17.3 days; p = 0.008)., Conclusions: Surgical stabilization of multiple rib fractures may improve the outcome in patients with multiple injuries and isolated chest wall trauma. Early surgical fixation leads to shorter length of stay and better outcomes., Level of Evidence: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

To examine if the application of Orem's self-care model could improve self-care knowledge, attitudes, practices, and respiratory conditions of trauma patients with chest tubes, a quasi-experimental study was conducted. The participants were assigned to two groups-namely, Orem's model and routine care. Although the patients' self-care knowledge, attitudes, and practices were improved in both groups over the course of 3 days since the initial assessments, there was a greater degree of improvement in the experimental group than that in the control group. However, there were no differences in the improvement of the chest parameters between the two groups. Orem's model was effective in improving self-care in patients with chest tube.

Unstable chest wall injuries can result from multiple rib fractures or a flail chest, and are associated with high rates of morbidity and mortality. Traditionally such injuries have been treated non-operatively, with mechanical ventilation when required, and pain management. Surgical treatment of these fractures is technically possible, and studies suggest improved outcomes, such as lower time on mechanical ventilation and length of time in the intensive care unit, compared to non-operative treatment. However, there are many challenges and controversies regarding indications for surgical fixation, patient selection, outcomes, and fixation strategy. Further research in this area is warranted to better answer these questions., (© 2018 Elsevier Ltd. All rights reserved.)

Rib fixation has become a strategy for patients with displaced rib fractures and hemo/pneumothoraces (HTX/PTX). Rib plating improves pain control and respiratory mechanics, thereby reducing recovery times and morbidity/mortality. Current treatment consists of chest tube placement, pain control, and pulmonary toilet. The addition of rib plating should reduce time till HTX/PTX resolution and chest tube removal. The study compares chest tube stay time in rib-plated patients with those managed with current treatment. We hypothesize that patients undergoing rib plating will have a reduction in chest tube stay times. A retrospective review of a Level 1 trauma registry was performed. Rib-plated patients (n = 70) from 2013 to 2015 were compared with a randomly selected, nonoperative, injury-matched, historical (2003-2008) control group (n = 60). Demographics were obtained. Independent variables analyzed include Injury Severity Score (ISS), intensive care unit days, length of stay, and chest tube stay times. 60 control patients had an average ISS of 19 and age of 51 years, compared with ISS of 20 and age of 56 years in plated patients. Plated patients had a reduction in chest tube days, 6.5 versus 8.4 days, P value = 0.02. Plated patients had 14 intensive care unit days versus 19 days, P value = 0.09. T tests were performed to confirm significance. Reduction in chest tube days improves patient pain and allows for improved ambulation and pulmonary toilet, helping reduce respiratory complications. Our review shows that plating may prove beneficial in reducing complications associated with management of HTX/PTX in the setting of rib fractures.

Background: Open reduction and internal fixation of rib fractures is recommended to decrease mortality, shorten the duration of mechanical ventilation, and lower hospital length of stay. Prosthetic titanium plates are frequently used to repair chest wall trauma, and are typically contoured to the patient's anatomy at the time of implant in the operating room. We describe the use of 3-dimensional (3D) digitally corrected rapid prototyping to generate a model of a patient's skeletal anatomy for the purposes of preoperative customization of standard titanium plates for fixation of rib fractures., Methods: A computed tomography imaging Digital Imaging and Communication in Medicine data set was segmented. Rib fractures were virtually realigned using the mirrored normal anatomy as a guide. The model was printed and used to customize titanium rib fixation plates prior to the procedure., Results: Preoperative shaping of 5 titanium plates using the final 3D model required a total of 5.65 minutes. Surgical fixation of 4 of the patient's 5 fractures was accomplished using the titanium plates that were preoperatively shaped using our 3D model., Discussion: We demonstrate successful use of a digitally rendered model to preoperatively customize standard titanium rib fixation plates. Compared with intraoperative contouring of rib fixation plates, we believe that this approach facilitates repair of complex rib fractures, saving time in the operating room. We believe this technique can improve the accuracy of reductions, increase the ease and efficiency of these procedures, and afford benefits in reducing surgical stress on patients who have already suffered significant trauma.

Several patients suffer from rib fractures after traumas, and in severe cases it can be life-threatening. Until recently, attempts to perform surgical fixation in patients with instability have been unsuccessful. Chronic non-union causes persistent pain, disability and loss of quality of life. Implementation of surgical stabilization of rib fractures with tailored plates seems to improve pain relief, especially in cases of non-union but also in patients with instability of the chest wall after severe traumas, where advanced pain treatment (epidural catheter) is insufficient or weaning off fails.

Objective: To determine the prevalence, management and outcomes of patients with flail chest injuries, compared to patients without flail chest injuries (single rib fractures and multiple rib fractures without a flail segment)., Design: Retrospective cohort study., Setting: Ontario, Canada., Participants: Ontario residents over the age of 16 years who had been admitted to hospital with a chest wall injury from 2004 to 2015 were identified using administrative health care databases., Main Outcome Measurements: Outcomes included treatment modalities such as rate of surgical repair, days on mechanical ventilation, days in the intensive care unit, days in hospital, rate of chest tube placement; and rates of complication, including pneumonia, tracheostomy, readmission, and death., Results: In total 117,204 patients with fractures of the chest wall were identified. Of the entire cohort, 1.5% of them had a flail chest injury, 41% had multiple rib fractures, and 58% had single rib fractures. Patients with flail chest injuries had significantly worse outcomes compared to patients with multiple rib fractures in all categories (P < 0.0001). Similarly, patients with multiple rib fractures had significantly worst outcomes compared with patients with single rib fractures (P < 0.0001). Only 4.5% of patients with flail chest injuries were treated surgically, however, the number increased from 1% before 2010 to 10% after 2010 (P < 0.0001). After adjustment for potential confounders, patients with flail chest injuries treated surgically had a reduced risk of early mortality compared to those treated nonoperatively (OR 0.16, P = 0.019)., Conclusions: Surgical stabilization of flail chest injuries has increased significantly in recent years. The results of this study provide preliminary evidence that the increasing rate of surgical intervention may be warranted by reducing mortality., Level of Evidence: Therapeutic Level II.
