Delayed hemothorax following blunt thoracic trauma: a case report.

BACKGROUND: Late hemothorax is a rare complication of blunt chest trauma. The longest reported time interval between the traumatic event and the development of hemothorax is 44 days. CASE PRESENTATION: An elderly patient with right-sided rib fractures from chest trauma, managed initially with closed thoracostomy, presented with a delayed hemothorax that occurred 60 days after initial management, necessitating conservative and then surgical intervention due to the patient's frail condition and associated complications. CONCLUSIONS: This case emphasizes the clinical challenge and significance of delayed hemothorax in chest trauma, highlighting the need for vigilance and potential surgical correction in complex presentations, especially in the elderly.

Surgical fixation of traumatic sternal manubrium dislocation and right-sided rib fractures following a motorcycle accident.

This brief report discusses the diagnosis, management and surgical intervention of a man in his 30s presenting with a rare traumatic sternal manubrium dislocation following a motorcycle crash, accompanied by multiple concomitant rib fractures. The severity and complexity of the patient's injuries necessitated an operative approach for his sternomanubrial dislocation, emphasising the importance of multidisciplinary coordination, accurate diagnosis and prompt surgical intervention. The report provides valuable insights into the successful application of open reduction and internal fixation with plating in a real-world setting, which resulted in positive patient outcomes, despite the rarity and severity of this type of trauma. It further underscores the need for additional research to advance best practices for managing traumatic sternal manubrium dislocations in the context of high-impact injuries.

Minimally Invasive Surgical Management of Chronic Cough-Induced Rib Fracture Non-Union: A Case Report.

BACKGROUND Nonunion of a rib fracture can cause chronic pain, and pharmacological pain management may lead to medication dependence. This report describes a 54-year-old man with a chronic cough and painful nonunion fracture of the left posterior 8th rib, managed with minimally invasive surgery and a rib splint. CASE REPORT A 54-year-old man presented with chronic cough-induced left chest wall pain. Three-dimensional chest computed tomography (CT) scan showed a nonunion of a fracture of the left posterior 8th rib. After medical management failure, we proposed a surgical approach with the aim to remove the tissue comprising the nonunion, release the nerve, and stabilize the bone stumps. To avoid the adverse effects of a large incision, we designed a minimally invasive strategy based on ultrasound fracture localization and the use of an intramedullary splint. The pain disappeared immediately after surgery. The patient was discharged in 24 hours. At 6-week follow-up, he was still asymptomatic, and a new CT scan reconfirmed the correct splint position. From the immediate postoperative evaluation until the last follow-up visit, he consistently reported full satisfaction. CONCLUSIONS This report has highlighted the challenges of management of chronic pain in nonunion of a rib fracture, and has described the use of a minimally invasive surgical approach. In this single case, our tailored surgical strategy achieved definitive success in pain management, minimizing postoperative complications/adverse effects and avoiding the addition of pain medications despite a 24-hour hospital stay. Our goal is to share an alternative solution for colleagues facing similar cases.

Management of non-union of rib fractures secondary to trauma: A scoping review.

OBJECTIVE: Rib fracture non-union is an uncommon complication of traumatic rib fractures. Our objective was to perform a scoping review of the literature for the management of rib fracture non-union. This included analysis of the variations in surgical technique, complications experienced, and reported outcomes. METHODS: We conducted a scoping review and searched databases (MEDLINE, CINAHL, and Embase). We performed abstract and full-text screening, and abstracted data related to pre-operative assessment, surgical technique, complications, and reported outcome measures. RESULTS: We included 29 articles of which 19 were case reports and 10 were case series. The data quality was generally heterogeneous. The studies included 229 patients and the commonest symptoms of rib fracture non-union included chest pain, clicking, dyspnea and deformities. The patients underwent surgical management of rib fracture non-union (excluding first rib fractures) using various techniques. The majority used surgical stabilization of rib fracture with or without a graft. The reported outcomes were inconsistent between studies, but showed high rates of union (>94 %), reduction in reported VAS scores, and improved return to work when included. Implant failure occurred in 10 % of the 229 total patients reported in our studies, the re-operation rate was 13 %, and the overall complication rate was 27 %. CONCLUSION: Surgical management of rib fracture non-union often involving locking plates and screws with or without a graft has been shown in several case reports and series as an effective treatment with acceptable implant failure and complication rates. Surgical management is therefore a viable option for symptomatic patients. Further research is required to determine optimal management strategies that further reduce surgical complications for these patients.

Benefits of Rib Fixation Utilizing Low-Cost Materials: A Randomized Pilot Trial.

INTRODUCTION: Surgical stabilization of rib fractures (SSRF) using standard rib plating systems has become a norm in developed countries. However, the procedure has not garnered much interest in low-middle-income countries, primarily because of the cost. METHODS: This was a single-center pilot randomized trial. Patients with severe rib fractures were randomized into two groups: SSRF and nonoperative management. SSRF arm patients underwent surgical fixation in addition to the tenets of nonoperative management. Low-cost materials like stainless steel wires and braided polyester sutures were used for fracture fixation. The primary outcome was to assess the duration of hospital stay. RESULTS: Twenty-two patients were randomized, 11 in each arm. Per-protocol analysis showed that the SSRF arm had significantly reduced duration of hospital stay (22.6 ± 19.1 d versus 7.9 ± 5.7 d, P value 0.031), serial pain scores at 48 h and 5 d (median score 5, IQR (3-6) versus median score 7, IQR (6.5-8), P value 0.004 at 48 h and median score 2 IQR (2-3) versus median score 7 IQR (4.5-7) P value 0.0005 at 5 d), significantly reduced need for injectable opioids (9.9 ± 3.8 mg versus 4.4 ± 3.4 mg, P value 0.003) and significantly more ventilator-free days (19.9 ± 8.7 d versus 26.4 ± 3.2 d, P value 0.04). There were no statistically significant differences in the total duration of ICU stay (median number of days 2, IQR 1-4.5 versus median number of days 7, IQR 1-14, P value 0.958), need for tracheostomy (36.4% versus 0%, P value 0.155), and pulmonary and pleural complications. CONCLUSIONS: SSRF with low-cost materials may provide benefits similar to standard rib plating systems and can be used safely in resource-poor settings.

Surgical stabilization of rib fractures in the geriatric trauma population is associated with equivalent outcomes to a younger cohort: A propensity matched analysis.

BACKGROUND: Surgical stabilization of rib fractures (SSRF) improves outcomes in chest wall trauma. Geriatric patients are particularly vulnerable to poor outcomes; yet, this population is often excluded from SSRF studies. Further delineating patient outcomes by age is necessary to optimize care for the aging trauma population. METHODS: A retrospective cohort study was conducted examining outcomes among patients aged 40+ for whom an SSRF consult was placed between 2017 and 2022 at a level 1 trauma center. Patients were categorized into geriatric (65+) and adult (40-64), as well as 80 years and older (80+) and 79 and younger (40-79). Patient outcomes were assessed comparing non-operative and operative management of chest wall trauma. Propensity matched analysis was performed to evaluate mortality differences between adult and geriatric patients who did and did not undergo SSRF. RESULTS: A total of 543 patients had an SSRF consult. Of these, 227 were 65+, and 73 were 80+. A total of 129 patients underwent SSRF (24 %). The percentage of patients undergoing SSRF did not vary between 40 and 64 and 65+ (23.7 % and 23.6 %, respectively, p = 0.97) or 40-79 and 80+ (24.0 vs 21.9, p = 0.69). Patients undergoing SSRF had higher chest injury burden and were more likely to require mechanical ventilation and ICU level care on admission. Overall, in-hospital mortality rate was 4.6 %. Among patients who underwent SSRF, mortality rate did not significantly differ between 65+ and 40-64 (7.8% vs 2.7 %, p = 0.18) or 80+ and 40-79 (6.3% vs 4.6 %, p = 0.77). This remained true in propensity matched analysis. CONCLUSION: Geriatric and octogenarian patients with rib fractures underwent SSRF at similar rates and achieved equivalent outcomes to their younger counterparts. SSRF did not differentially affect mortality outcomes based on age group in propensity matched analysis. SSRF is safe for geriatric patients including octogenarians.

Return to work and activity after rib-fixation for acute chest trauma: first application of a validated patient-reported outcomes assessment tool.

OBJECTIVES: Rib fractures present a heavy pain and functional burden in trauma. Our primary aim was to determine return to work in patients with acute rib fractures requiring surgical stabilization of rib fractures. Our secondary outcomes were pain and quality of life. We also document the first application of the Work Productivity and Activity Impairment Instrument, a validated injury-specific patient-reported outcome measure, for chest wall injury in the literature. METHODS: A retrospective review was conducted on patients with rib fractures requiring surgical fixation in a single centre between 2008 and 2020. After applying inclusion and exclusion criteria to ensure relevance, all eligible patients were asked to complete patient-reported outcome measure questionnaires. RESULTS: Of 1841 trauma patients with rib fractures, 66 underwent surgical fixation. Thirty-nine patients were eligible and 31 completed the questionnaires. Pre-injury and post-injury answers were compared. The number of patients in employment decreased postoperatively from 22 to 16 (P = 0.006). For those who returned to work, there was no difference in hours missed but reduced weekly hours and productivity scores. There were significantly more patients with pain and on pain relief. There was a lower quality of life score postoperatively. CONCLUSIONS: Approximately 1 in 5 patients who require surgical fixation for rib fractures will not return to work. This is the first chest wall trauma study that uses the Work Productivity and Activity Impairment Instrument, a validated tool for work productivity outcomes. We recommend this instrument as a reliable tool for investigating return-to-work outcomes in trauma patients.

[Experience with Surgical Stabilization for Traumatic Rib Fractures and Sternal Fractures].

The treatment of traumatic rib fractures and sternal fractures have focused on pain and respiratory management, and conservative treatment has been recommended. Recently, however, a number of case series from abroad have been reported and demonstrated the usefulness of surgical stabilization of rib fractures (SSRF) and sternal fractures (SSSF). We have experienced seven cases of SSRF and two cases of SSSF at International University Health and Welfare Narita Hospital and Atami Hospital. Based on our experienced cases, we have outlined the preoperative evaluation, indication for surgery, timing of surgery, surgical techniques, and postoperative course. Of these nine cases, the clinical course of two cases of SSRF and one case of SSSF were detailly presented. The surgical indications and techniques for traumatic rib fractures and sternal fractures vary from institution to institution, and there is no single optimal treatment. We hope that the accumulation of cases, and discussions will help to build a higher quality evidence for surgical treatment of thoracic trauma in Japan.

The application of electrical impedance tomography and surgical outcomes of thoracoscope-assisted surgical stabilization of rib fractures in severe chest trauma.

Serious blunt chest trauma usually induces hemothorax, pneumothorax, and rib fractures. More studies have claimed that early video-assisted thoracoscopic surgery with surgical stabilization of rib fractures (SSRF) results in a good prognosis in patients with major trauma. This study aimed to verify the outcomes in patients with chest trauma whether SSRF was performed. Consecutive patients who were treated in a medical center in Taiwan, for traumatic events between January 2015 and June 2020, were retrospectively reviewed. This study focused on patients with major trauma and thoracic injuries, and they were divided into groups based on whether they received SSRF. We used electrical impedance tomography (EIT) to evaluate the change of ventilation conditions. Different scores used for the evaluation of trauma severity were also compared in this study. Among the 8396 patients who were included, 1529 (18.21%) had major trauma with injury severity score > 16 and were admitted to the intensive care unit initially. A total of 596 patients with chest trauma were admitted, of whom 519 (87%) survived. Younger age and a lower trauma score (including injury severity scale, new injury severity score, trauma and injury severity score, and revised trauma score) account for better survival rates. Moreover, 74 patients received SSRF. They had a shorter intensive care unit (ICU) stay (5.24, p = 0.045) and better performance in electrical impedance tomography (23.46, p < 0.001). In patients with major thoracic injury, older age and higher injury survival scale account for higher mortality rate. Effective surgical stabilization of rib fractures shortened the ICU stay and helped achieve better performance in EIT. Thoracoscope-assisted rib fixation is suggested in severe trauma cases.

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

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

[A Review of 70 Cases of Thoracic Trauma with Rib Fixation:Indications and Practical Innovations of the Procedure].

We summarized the experience of surgical stabilization of rib fractures (SSRF) at a core hospital in eastern Hiroshima, which is a primary center for tertiary emergency medical care, especially for high-energy trauma cases including chest injuries. The study focuses on patients who underwent SSRF from January 2016 to September 2023, analyzing patient characteristics, injury mechanisms, associated injuries, fracture locations, time from injury to surgery, fixation devices used, and postoperative outcomes. Our hospital primarily treats elderly patients, and falls are the most common cause of injury, followed by traffic accidents. The criteria for SSRF in our hospital were clinical manifestations of flail chest, need for lung repair, persistent pain, or improvement of thoracic deformity. We had a high rate of fixation of fractures of the 4th-10th ribs, which have a significant impact on respiratory mechanics; although KANI plates were primarily used, the introduction of MatrixRIB plates offers advantages in certain scenarios. The study also identified challenges with the KANI plate, including cases of plate dislodgement, particularly in patients with multiple fractures and severe thoracic deformities. The combination of video-assisted thoracoscopic surgery and SSRF allows for more effective rib fixation and reduces surgical wound size and muscle damage.

[Surgical Stabilization of Traumatic Multiple Rib Fractures Using Absorbable Osteosynthesis Agent(u-HA/PLLA Composite Material)].

In case that met several indication criteria with 4 or more rib fractures, we performed surgical stabilization of multiple fractured ribs using a plate and screw system( Super FIXORB MX) that was made of uncalcined hydroxyapatite (u-HA)/poly-L-lactic acid (PLLA) composite material with excellent bioactivity and absorbability. We report our clinical experience of 7 cases in which this device was used. Although there is still room for further consideration of the technique and the strength of the device itself, computed tomography( CT) images taken 9 months after surgery showed that the fixative device was almost assimilated with the bone at the fracture repair site in cases where fixation was successful.

[The Surgical Indication of Multiple Rib Fractures of Patients by Traumas and Timing of the Surgical Stabilization of Rib Fractures].

It's reported that 10% of the inpatients by traumas have fractured ribs. It's easy to judge if it's the case of flail chest, or respiratory failure due to airway injury or pulmonary contusion. There is no guideline for treatments of a patient who has multiple ribs fractures without respiratory failure. We did the surgical stabilization of rib fractures for 10 cases from 2020 to October 2023. As a result, we find out useful surgical indication for treatment of rib fractures.

[Outcomes of Surgical Treatment for Chest Trauma].

BACKGROUND: Intra-thoracic organ bleeding and chest wall injury following chest trauma can easily lead to life-threatening emergencies and a delay in treatment may lead to fatal outcomes. Interestingly, the optimal timing, indications, and surgical techniques have not been standardized. METHOD: We retrospectively analyzed 35 patients who underwent surgical treatment for chest trauma. RESULTS: All patients with penetrating trauma (n=4) underwent emergency surgery for a hemothorax. There were no postoperative complications or hospital deaths. All patients with blunt trauma( n= 31) had multiple rib fractures;rib fixation was performed in 29 patients( 94%). Eight patients( 26%) had flail chest. The duration from injury to surgery averaged 7.5 days. The prognosis was generally favorable with no postoperative complications, but two patients died in the hospital due to multiple organ failure caused by high-energy trauma. Patients with flail chest or multiple organ injury had prolonged postoperative hospital stays. CONCLUSIONS: Patients who sustain chest trauma follow various clinical courses. Appropriate timing of surgical intervention at an early stage after injury can be life saving and hasten a functional recovery.

Surgical stabilization of rib fractures: The impact of volume and the need for standardized indications.

INTRODUCTION: We aimed to examine impact of trauma center (TC) surgical stabilization of rib fracture (SSRF) volume on outcomes of patients undergoing SSRF. METHODS: Blunt rib fracture patients who underwent SSRF were included from ACS-TQIP2017-2021. TCs were stratified according to tertiles of SSRF volume:low (LV), middle, and high (HV). Outcomes were time to SSRF, respiratory complications, prolonged ventilator use, mortality. RESULTS: 16,872 patients were identified (LV:5470,HV:5836). Mean age was 56 years, 74% were male, median thorax-AIS was 3. HV centers had a lower proportion of patients with flail chest (HV41% vs LV50%), pulmonary contusion (HV44% vs LV52%) and had shorter time to SSRF(HV58 vs LV76 â€‹h), less respiratory complications (HV3.2% vs LV4.5%), prolonged ventilator use (HV15% vs LV26%), mortality (HV2% vs LV2.6%) (all p â€‹< â€‹0.05). On multivariable regression analysis, HV centers were independently associated with reduced time to SSRF(ߠ​= â€‹-18.77,95%CI â€‹= â€‹-21.30to-16.25), respiratory complications (OR â€‹= â€‹0.67,95%CI â€‹= â€‹0.49-0.94), prolonged ventilator use (OR â€‹= â€‹0.49,95%CI â€‹= â€‹0.41-0.59), but not mortality. CONCLUSIONS: HV SSRF centers have improved outcomes, however, there are variations in threshold for SSRF and indications must be standardized. LEVEL OF EVIDENCE: Level III. STUDY TYPE: Therapeutic/Care Management.

Symptomatic rib fracture nonunion: a systematic review of the literature.

INTRODUCTION: Rib fractures commonly occur in trauma patients with varying presentations. Though the literature in recent years has moved toward favoring more early intervention of acute rib fractures, little has been reported on the matter of surgical fixation for symptomatic rib fracture nonunions. MATERIALS AND METHODS: We performed a review of PubMed and Cochrane databases for articles published since 2000. Inclusion criteria were studies with greater than six months of follow-up, while case studies were excluded. A thorough analysis was performed on patient outcomes, complications reported, operative techniques utilized, and fixation systems used, among other parameters reported by the articles. RESULTS: One hundred and thirty-nine studies resulted from our review, and a total of nine studies met our inclusion criteria with a combined total of 182 patients who underwent open reduction and internal fixation for symptomatic rib fracture nonunions. All studies reported a significant reduction of pain with increased satisfaction in the majority of patients. There were a total of 71 postoperative complications, the most common of which included surgical site infections, hardware failure, and hematoma. The most serious complications were insulting injury to the lung parenchyma or pleura; however, these were extremely rare based off the current literature. The use of bone grafting was common with eight of the nine studies mentioning the benefits of grafting. CONCLUSION: Surgical stabilization of rib fracture nonunions appears to be an appropriate treatment alternative, and various techniques and approaches may be used with similar success. Further studies with higher level of evidence are recommended on the subject.

A meta-analysis and trial sequential analysis of randomised controlled trials comparing nonoperative and operative management of chest trauma with multiple rib fractures.

BACKGROUND: Operative treatment of traumatic rib fractures for better outcomes remains under debate. Surgical stabilization of rib fractures has dramatically increased in the last decade. This study aimed to perform a systematic review and meta-analysis of randomised controlled trials (RCTs) to assess the effectiveness and safety of operative treatment compared to conservative treatment in adult patients with traumatic multiple rib fractures. METHODS: A systematic literature review was performed according to the preferred reporting items for systematic reviews and meta-analyses guidelines. We searched MEDLINE, Scopus, and Cochrane Central Register of Controlled Trials and used the Cochrane Risk-of-Bias 2 tool to evaluate methodological quality. Relative risks with 95% confidence interval (CI) were calculated for outcomes: all-cause mortality, pneumonia incidence, and number of mechanical ventilation days. Overall certainty of evidence was evaluated with the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach, with trial sequential analysis performed to establish implications for further research. RESULTS: From 719 records, we included nine RCTs, which recruited 862 patients. Patients were assigned to the operative group (received surgical stabilization of chest wall injury, n = 423) or control group (n = 439). All-cause mortality was not significantly different (RR = 0.53; 95% CI 0.21 to 1.38, P = 0.35, I2 = 11%) between the two groups. However, in the operative group, duration of mechanical ventilation (mean difference -4.62; 95% CI -7.64 to -1.60, P < 0.00001, I2 = 94%) and length of intensive care unit stay (mean difference -3.05; 95% CI -5.87 to -0.22; P < 0.00001, I2 = 96%) were significantly shorter, and pneumonia incidence (RR = 0.57; 95% CI 0.35 to 0.92; P = 0.02, I2 = 57%) was significantly lower. Trial sequential analysis for mortality indicated insufficient sample size for a definitive judgment. GRADE showed this meta-analysis to have very low to low confidence. CONCLUSION: Meta-analysis of large-scale trials showed that surgical stabilization of multiple rib fractures shortened the duration of mechanical ventilation and reduced the incidence of pneumonia but lacked clear evidence for improvement of mortality compared to conservative treatment. Trial sequential analysis suggested the need for more cases, and GRADE highlighted low certainty, emphasizing the necessity for further targeted RCTs, especially in mechanically ventilated patients.

Management of Blunt Chest Trauma.

Common mechanisms of blunt thoracic injury include motor vehicle collisions and falls. Chest wall injuries include rib fractures and sternal fractures; treatment involves supportive care, multimodal analgesia, and pulmonary toilet. Pneumothorax, hemothorax, and pulmonary contusions are also common and may be managed expectantly or with tube thoracostomy as indicated. Surgical treatment may be considered in select cases. Less common injury patterns include blunt trauma to the tracheobronchial tree, esophagus, diaphragm, heart, or aorta. Operative intervention is more often required to address these injuries.

Impact of obesity on outcomes after surgical stabilization of multiple rib fractures: Evidence from the US nationwide inpatient sample.

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

The therapeutic value of vacuum external fixation in polytrauma patients with multiple ribs fracture.

BACKGROUND: Multiple displaced rib fractures often result in a poor prognosis. Open reduction and internal fixation has been shown to provide benefits for patients with displaced rib fractures and flail chest. Nevertheless, for patients who are unwilling or unsuitable for surgery, the therapeutic options are limited. We developed a novel plastic vacuum device for rib fractures external stabilization. This study aims to compare the therapeutic efficacy of this device against a traditional chest strap in polytrauma patients with multiple rib fractures. METHODS: A retrospective investigation was conducted on polytrauma patients with multiple rib fractures admitted to our trauma center between March 2020 and March 2023. Patients were categorized into two groups: vacuum external fixation and chest strap. Comparative analysis was conducted on baseline parameters, injury characteristics, and clinical outcomes between the two groups. RESULTS: In this study, 54 patients were included, with 28 receiving chest strap and 26 undergoing vacuum external fixation. Results showed that, at 3 days and 7 days postintervention, the vacuum external fixation group had significantly lower visual analog scale scores during deep breathing and coughing (P < .05). Vacuum external fixation also reduced pleural drainage duration and volume, as well as lowered the risk of pneumonia and other complications (P < .05). Furthermore, the vacuum external fixation group demonstrated notable improvements in vital capacity, tidal volume, blood-gas test results, and a shorter hospital length of stay. CONCLUSIONS: According to the study findings, vacuum external fixation appears to offer benefits to patients with multiple rib fractures, potentially reducing the risk of complications and improving overall clinical outcomes.
