Fixation of rib fractures is beneficial for patients with chronic obstructive pulmonary disease, a trauma quality improvement program study.

BACKGROUND: Internal fixation for multiple rib fractures is well established. Patients with underlying chronic obstructive pulmonary disease (COPD) have a higher rate of perioperative complications. It is unclear if these patients are suitable candidates for internal fixation and if surgical interventions are harmful to these patients. STUDY DESIGN AND METHODS: Adult patients with ≥ 3 rib fractures and underlying COPD from the Trauma Quality Improvement Program between 2017 and 2019 were eligible for inclusion. The patients were divided into two treatment groups: operative and non-operative. Furthermore, inverse probability treatment weighting was applied to analyze mortality and adverse hospital events. RESULTS: Patients with COPD in the operative group had higher ventilator use (odds ratio [OR], 3.211; 95% confidence interval [CI], 1.993-5.175; p < 0.001). Additionally, they had a longer length of stay (coefficient ß, 4.139; standard error, 0.829; p < 0.001) and longer ventilator days (coefficient ß, 1.937; standard error, 0.655; p = 0.003) than in the non-operative group. Furthermore, the mortality rate was lower in the operative group than in the non-operative group (OR, 0.426; 95% CI, 0.228-0.798; p = 0.008). CONCLUSION: Internal fixation of rib fractures plays a crucial role in patients with underlying COPD disease. They presented a better mortality rate without an increased perioperative complication rate.

Excision of Giant Chronic Expanding Hematoma of the Thorax Caused by Rib Fractures after Proton Radiotherapy for Lung Cancer.

Chronic expanding hematoma (CEH) is defined as a hematoma that gradually expands over months to years. An 82-year-old female underwent proton radiotherapy for left upper lobe lung cancer 10 years previously. Two years after the therapy, a hematoma developed from the left 3rd to 5th dorsal rib fractures and gradually expanded, causing contraction of the left shoulder. Transcatheter arterial embolization was performed; however, the hematoma continued to expand with thrombocytopenia, and the platelet was decreased to 4.2 × 104/µL. Computed tomography showed a 17.2 × 14.0 × 10.0 cm mass between the left scapula and left dorsal ribs. The CEH of the thorax was completely excised with combined resection of the 3rd to 5th ribs, while the brachial plexus was preserved. Postoperatively, the platelet completely recovered and she could raise her left arm. A complete excision with surrounding organs preserved is the strategy used in the treatment of CEH of the thorax.

Comprehensive analysis of risk factors for postoperative wound infection following open reduction and internal fixation of Rib fractures.

BACKGROUND: Postoperative wound infections (PWIs) significantly impact patient outcomes following open reduction and internal fixation (ORIF) of rib fractures. Identifying and understanding risk factors associated with these infections are crucial for improving surgical outcomes and patient care. METHODS: This retrospective study, conducted from January 2020 to October 2023 at our institution, aimed to analyze the risk factors for PWIs in patients undergoing ORIF for rib fractures. A total of 150 patients were included, with 50 in the infected group and 100 in the non-infected control group, matched for demographic and clinical characteristics. Data on variables such as intraoperative blood loss, hospital stay duration, body mass index (BMI), operation time, presence of anemia, drainage time, diabetes mellitus status, smoking habits, and age were collected. Statistical analysis involved univariate and multivariate logistic regression using SPSS software (Version 27.0), with p-values < 0.05 considered statistically significant. RESULTS: Univariate analysis revealed no significant association between intraoperative blood loss or hospital stay duration and PWIs. However, operation time ≥ 5 h, anemia, drainage time ≥ 7 days, diabetes mellitus, smoking, and age ≥ 60 years were significantly associated with higher PWI rates. Multivariate logistic regression confirmed these factors as independent predictors of PWIs, with operation time and diabetes mellitus showing particularly strong associations. CONCLUSIONS: Prolonged operation time, anemia, extended drainage, diabetes mellitus, smoking, and advanced age significantly increase the risk of PWIs following ORIF for rib fractures. Early identification and targeted management of these risk factors are essential to reduce the incidence of infections and improve postoperative outcomes.

[Dynamic tracheal collapse in a wagyu calf with multiple rib fractures after dystocia]. / Ein dynamischer Trachealkollaps bei einem Wagyukalb mit multiplen Rippenfrakturen nach einer Schwergeburt.

A dynamic tracheal collapse caused by multiple rib fractures in a neonatal wagyu calf was diagnosed by radiography, endoscopy and computed tomography. Conservative treatment, consisting of the medical treatment of respiratory inflammation and the reduction of environmental and social stress was initiated. The respiratory signs improved significantly, and the calf was discharged. The condition deteriorated after several weeks without treatment, most likely due to of excessive callus formation of the fractured ribs causing increased reduction in tracheal diameter.

Cumulative rib fracture risk after stereotactic body radiotherapy in patients with localized non-small cell lung cancer.

INTRODUCTION: Rib fracture is a known complication after stereotactic body radiotherapy (SBRT). Patient-related parameters are essential to provide patient-tailored risk estimation, however, their impact on rib fracture is less documented compared to dosimetric parameters. This study aimed to predict the risk of rib fractures in patients with localized non-small cell lung cancer (NSCLC) post-SBRT based on both patient-related and dosimetric parameters with death as a competing risk. MATERIALS AND METHODS: In total, 602 patients with localized NSCLC treated with SBRT between 2010-2020 at Odense University Hospital, Denmark were included. All patients received SBRT with 45-66 Gray (Gy)/3 fractions. Rib fractures were identified in CT-scans using a word embedding model. The cumulative incidence function was based on cause-specific Cox hazard models with variable selection based on cross-validation model likelihood performed using 50 bootstraps. RESULTS: In total, 19 % of patients experienced a rib fracture. The cumulative risk of rib fracture increased rapidly from 6-54 months post-SBRT. Female gender, bone density, near max dose to the rib, V30 and V40 to the rib, gross tumor volume, and mean lung dose were significantly associated with rib fracture risk in univariable analysis. The final multi-variable model consisted of V20 and V30 to the rib and mean lung dose. CONCLUSION: Female gender and low bone density in male patients are significant predictors of rib fracture risk. The final model predicting cumulative rib fracture risk of 19 % in patients with localized NSCLC treated with SBRT contained no patient-related parameters, suggesting that dosimetric parameters are the primary drivers.

Prognostic factors for outcomes following surgical stabilization of rib fractures: A review of the literature.

Rib fractures are a common injury following blunt thoracic trauma, often resulting in high levels of morbidity and mortality. With the ageing global population, the incidence of rib fractures is expected to increase, posing a significant burden on healthcare systems worldwide. With advancements in surgical techniques and pioneering research on the topic the use of surgical stabilisation of rib fractures (SSRF) has increased significantly over the past two decades. However, the relationship between certain prognostic factors and patient outcomes following surgery is still contested and there lacks a consensus on definitive indications for the operation. This literature review presents the current research on SSRF outcomes for; patients with flail chest injuries and multiple-non flail rib fractures, optimal timing between injury and operation, and patient age. This article contributes to the ongoing dialogue surrounding chest wall trauma management and may be drawn upon to aid future research and develop clinical practice guidelines.

Global burden of fracture of sternum and/or ribs: An analysis of 204 countries and territories between 1990 and 2019.

BACKGROUND: Sternum and rib fractures represent a significant global health concern, contributing to morbidity and disability on a worldwide scale. However, there is a notable lack of recent epidemiological data detailing the global and regional burden of these fractures. METHODS: We undertook a systematic analysis of the prevalence of sternum and rib fractures at the global, regional, and national levels in 2019, while also examining time trends spanning from 1990 to 2019. To achieve this, we extracted data from the Global Burden of Disease Study 2019, enabling us to determine incidence, prevalence, years lived with disability (YLDs), and their corresponding age-standardized rates. RESULTS: In 2019, there were 4.1 million incident cases and 2 million prevalent cases of sternum and rib fractures worldwide. These figures represent increases of 43.7 % and 64.1 %, respectively, since 1990. YLDs also exhibited a notable increase, rising by 62.4 % to reach 190,834 cases. However, since 1990, their equivalent age-standardized rates, which ranged from 5.5 % to 7.1 %, have decreased. Notably, China had the greatest incidence (1.2 million cases), prevalence (573,000 cases), and number of YLDs (55,400 cases), all in 2019. The greatest age-standardized incidence rate (143/100,000) and age-standardized prevalence rate (65/100,000) were both recorded in Greenland in the same year. It's critical to emphasize that men experience these fractures at considerably higher rates than women. Around 70 % of incident instances included unintentional injuries worldwide and across all regions. High-socioeconomic regions had the highest rates of incidence, prevalence, and YLDs, albeit these rates have declined by 6.4 % to 7.1 % since 1990, whereas low-middle and low-income areas have had rises. CONCLUSIONS: This study, which spans the years 1990 to 2019, provides a thorough and current assessment of the global burden attributed to sternum and rib fractures. In terms of nations, regions, sociodemographic index (SDI) levels, age groups, genders, and reasons, it reveals significant variances and trends. The knowledge obtained from this study can be extremely useful in formulating health policy, allocating resources, and developing methods to prevent these injuries.

A bone tumor-like chest wall mass lesion with pathological rib fractures observed 13 years after lung stereotactic body radiotherapy: A case report.

Although stereotactic body radiotherapy (SBRT) is a curative treatment option for stage I non-small cell lung cancer (NSCLC), limited data are available regarding chest wall (CW) toxicities during an extended follow-up of over 10 years. We report an unusual case of a bone tumor-like CW mass lesion with pathological rib fractures observed 13 years after SBRT for peripheral lung cancer. Despite the initial suspicion of radiation-induced sarcoma, a subsequent incisional biopsy revealed no evidence of malignancy, and a definitive diagnosis of osteonecrosis was made. Thus, long-term observation of over 10 years is required to identify late chronic complications following SBRT.

Percutaneous Cryoneurolysis for Pain Control After Rib Fractures in Older Adults.

This case series evaluates changes in numeric pain scores, opioid use, and other measures before, during, and 30 days after computed tomography­guided percutaneous cryoneurolysis in patients with rib injury.

Therapeutic efficacy of platelet-rich plasma in the management of rib fractures.

BACKGROUND: This study aimed to investigate the therapeutic efficacy of platelet-rich plasma (PRP) therapy in patients with rib fractures. METHODS: This study retrospectively collected data from patients with acute rib fractures at Ming-Sheng General Hospital from 2020 to 2022 and excluded those who underwent surgical intervention or with severe extrathoracic injuries. PRP was extracted using the patient's blood and injected via ultrasound guidance near the fracture site. Patients self-assessed pain levels and medication usage at 0, 1, 2, 4, and 8 weeks. Pulmonary function tests were conducted at 4 weeks. RESULTS: This study included 255 patients, with 160 and 95 patients in the conservative (only pain medications administered) and PRP groups (PRP and analgesics administered), respectively. The PRP group reported lower pain levels than the conservative group at 2 and 4 weeks. No substantial differences in medication usage were observed between the groups. The PRP group demonstrated lower pain levels and medication usage than the conservative group in severe rib fractures (≥3 ribs) and better lung function improvement at 4 weeks. After propensity score matching, the PRP group still had a better treatment outcome in pain control and lung function recovery. CONCLUSION: PRP demonstrated considerable therapeutic efficacy in patients with severe rib fractures, resulting in reduced pain, decreased medication usage, and improved lung function but with no substantial benefits in patients with mild rib fractures.

Shoulder Pain - Don't Forget First Rib Fractures.

First rib fractures are uncommon, mainly in paediatric population, considering its anatomic features and their skeleton plasticity. Traditional teaching usually characterizes it as a hallmark of severe trauma. Herein, to unfold awareness to an unnoticed diagnosis, we describe two paediatric cases of isolated first rib fracture in adolescents without a clear identifiable cause nor an underlining trauma mechanism. Neurovascular injuries should always be investigated, as fracture of the first rib with ensuing callus formation is a rare but fearing cause of thoracic outlet syndrome. We highlight the scarcity of reports on isolated first rib fractures outside of sports medicine, as well as the importance of considering this otherwise easily missed diagnosis in a common complaint in children.

Pneumothorax contralateral to traumatic costal fractures.

In this case report, a 19-year-old woman suffered a high-energy trauma to her left side with multiple left-sided fractures, including ribs 8-12, with no pneumothorax on the left side, but a large right-sided pneumothorax. Contralateral pneumothorax is extremely rare in primarily unilateral trauma, especially when no contralateral rib fractures are present. A possible explanation is that of a barotrauma due to increased intrathoracic pressure with external compression. Careful examination of both sides of the body is necessary when evaluating patients with unilateral trauma, as serious organ injury may occur contralaterally.

Surgical stabilization of rib fractures in anticoagulated patients: Proceed with caution?

BACKGROUND: Surgical stabilization of rib fractures (SSRF) is increasingly performed, however the outcome of patients undergoing SSRF while on pre-injury antithrombotic therapy remains unknown. We compared surgical variables and outcomes of patients who were and were not on antithrombotic therapy. We hypothesize pre-injury anticoagulation is associated with delay in SSRF and worse outcomes. METHODS: For this retrospective cohort study, we queried the Chest Injury International Database, for patients undergoing SSRF between 08/2018 and 03/2022. Antithrombotic therapy was categorized into antiplatelet and anticoagulant use. Primary outcome was time from admission to SSRF. Secondary outcomes included SSRF duration and complications. Numerical data were presented as median (IQR), categorical data as number (%). Inverse probability weighting was used to control for confounding. RESULTS: Two hundred and eighteen SSRF patients were included, 25 (11 %) were on antithrombotic therapy. These patients were older (72 years, (65-80) versus 57 years, (43-66); p < 0.001) with lower ISS (14, (10-20) versus 21, (14-30); p = 0.002). Time from admission to SSRF was comparable (2 days, (1-4) versus 2 days, (1-4); p = 0.37) as was operative time (154 mins, (120.0-212.0) versus 177 mins, (143.0-210.0); p = 0.34). Patients using antithrombotics had fewer ICU-free days (24 (22-26) versus 28 (23-28); p = 0.003) but more ventilator free days (28, (28-28) versus 27 (27-28); p < 0.008). After adjusting for confounding, pre-injury anticoagulation was not significantly associated with delayed SSRF (Relative Risk, RR=1.37, 95 % CI 0.30-6.24), operative time (RR=1.07, 95 % CI0.88-1.31), IFD <=28 (RR=2.05, 95 %CI:0.33-12.67), VFD<=27 (RR=0.71, 95 %CI:0.15-3.48) or complications (RR=0.55, 95 % CI0.06-5.01). CONCLUSION: Pre-injury antithrombotic drug use neither delayed SSRF nor impacted operative time in patients requiring SSRF and was not associated with increased risk of complications. Our data suggest SSRF can be safely performed without delay in patients who use anticoagulation pre-injury. LEVEL OF EVIDENCE: IV. STUDY TYPE: Therapeutic/care management.

The Next Generation: Surgeon Learning Curve in a Mature Operative Rib Management Program.

INTRODUCTION: Prior work has demonstrated utility in using operative time to measure surgeon learning for surgical stabilization of rib fractures (SSRF); however, no studies have used operative time to evaluate the benefit of proctoring in subsequent generations of surgeons. We sought to evaluate whether there is a difference in learning between an original series (TOS) of self-taught surgeons versus the next generation (TNG) of proctored surgeons using cumulative summation (CUSUM) analysis. We hypothesized that TNG would have a comparatively accelerated learning curve. METHODS: A single-center retrospective review of all SSRF at a level 1 trauma center was performed. Data were collected from the beginning of an operative chest injury program to include at least 2 y of TNG experience. Operative time was used to determine success and misstep based on prior methods. Learning curves using CUSUM analysis were calculated based on an anticipated success rate of 90% and compared between TOS and TNG groups. RESULTS: Over 7 y, 163 patients with a median Injury Severity Score of 24 underwent SSRF. Median operative time was 165 min with a 0.5 plate-to-fracture ratio. All three TOS surgeons experienced a positive slope indicative of early missteps for their first 15-20 cases. By contrast, all three TNG surgeons demonstrated a series of early successes resulting in negative CUSUM slopes which coincided with a period of proctoring. By the end of TNG series, the composite cumulative score was less than half of the TOS surgeon' scores. CONCLUSIONS: Operative time continues to be a useful surrogate for observing SSRF learning curves. In a mature institutional program, proctored novice surgeons appear to have an accelerated learning curve compared to novice surgeons developing a new operative rib program.

Intercostal nerve electrodiagnostic testing in rib fractures.

INTRODUCTION/AIMS: Intercostal nerve injury can occur after rib fractures, resulting in denervation of the abdominal musculature. Loss of innervation to the rectus abdominis and intercostal muscles can cause pain, atrophy, and eventual eventration, which may be an underrecognized and thus undertreated complication of rib fractures. We investigated the clinical utility of intercostal nerve electrodiagnostic testing following rib fractures to diagnose and localize nerve injury at levels T7 and below. METHODS: Five patients with displaced bicortical rib fractures involving the 7th-11th ribs and clinical eventration of the ipsilateral abdominal wall underwent intercostal nerve conduction studies (NCS) and needle electromyography (EMG) on the affected side. EMG of the rectus abdominis and intercostal muscles was performed with ultrasound guidance, and ultrasound measurements of rectus abdominis thickness were obtained to assess for atrophy. RESULTS: Average patient age was 59.4 years and average body mass index (BMI) was 31.5 kg/m2. Intercostal NCS and EMG were able to reliably diagnose and localize intercostal nerve damage after rib fractures. Ultrasound demonstrated an average rectus abdominis transverse cross-sectional thickness of 0.534 cm on the affected side, compared with 1.024 cm on the non-affected side. DISCUSSION: Intercostal electrodiagnostic studies can diagnose and localize intercostal nerve damage after displaced rib fractures. Musculoskeletal ultrasound can be used to diagnose and quantify rectus abdominis atrophy and to accurately and safely guide needle EMG to the intercostal and rectus abdominis muscles.
