Randomized Controlled Trial of Surgical Rib Fixation to Nonoperative Management in Severe Chest Wall Injury.

OBJECTIVE: To compare the effectiveness of surgical stabilization of rib fractures (SSRFs) to nonoperative management in severe chest wall injury. BACKGROUND: SSRF has been shown to improve outcomes in patients with clinical flail chest and respiratory failure. However, the effect of SSRF outcomes in severe chest wall injuries without clinical flail chest is unknown. METHODS: Randomized controlled trial comparing SSRF to nonoperative management in severe chest wall injury, defined as: (1) a radiographic flail segment without clinical flail or (2) ≥5 consecutive rib fractures or (3) any rib fracture with bicortical displacement. Randomization was stratified by the unit of admission as a proxy for injury severity. Primary outcome was hospital length of stay (LOS). Secondary outcomes included intensive care unit (ICU) LOS, ventilator days, opioid exposure, mortality, and incidences of pneumonia and tracheostomy. Quality of life at 1, 3, and 6 months was measured using the EQ-5D-5L survey. RESULTS: Eighty-four patients were randomized in an intention-to-treat analysis (usual care = 42, SSRF = 42). Baseline characteristics were similar between groups. The numbers of total fractures, displaced fractures, and segmental fractures per patient were also similar, as were the incidences of displaced fractures and radiographic flail segments. Hospital LOS was greater in the SSRF group. ICU LOS and ventilator days were similar. After adjusting for the stratification variable, hospital LOS remained greater in the SSRF group (RR: 1.48, 95% CI: 1.17-1.88). ICU LOS (RR: 1.65, 95% CI: 0.94-2.92) and ventilator days (RR: 1.49, 95% CI: 0.61--3.69) remained similar. Subgroup analysis showed that patients with displaced fractures were more likely to have LOS outcomes similar to their usual care counterparts. At 1 month, SSRF patients had greater impairment in mobility [3 (2-3) vs 2 (1-2), P = 0.012] and self-care [2 (1-2) vs 2 (2-3), P = 0.034] dimensions of the EQ-5D-5L. CONCLUSIONS: In severe chest wall injury, even in the absence of clinical flail chest, the majority of patients still reported moderate to extreme pain and impairment of usual physical activity at one month. SSRF increased hospital LOS and did not provide any quality of life benefit for up to 6 months.

Rib fractures in the elderly population: a systematic review.

BACKGROUND: Multiple rib fractures are associated with significant morbidity and mortality, especially in elderly patients. There is growing interest in surgical stabilization in this subgroup of patients. This systematic review compares conservative treatment to surgical fixation in elderly patients (older than 60 years) with multiple rib fractures. The primary outcome is mortality. Secondary outcomes include hospital and intensive care length of stay (HLOS and ILOS), duration of mechanical ventilation (DMV) and pneumonia rates. METHODS: Multiple databases were searched for comparative studies reporting on conservative versus operative treatment for rib fractures in patients older than 60 years. Both observational studies and randomised clinical trials were considered. RESULTS: Five observational studies (n = 2583) were included. Mortality was lower in operatively treated patients compared to conservative treatment (4% vs. 8%). Pneumonia rate and DMV were similar (5/6% and 5.8/6.5 days) for either treatment modality. Overall ILOS and HLOS of stay were longer in operatively treated patients (6.5 ILOS and 12.7 HLOS vs. 2.7 ILOS and 6.5 ILOS). There were only minimal reports on perioperative complications. Notably, the median number of rib fractures (8.4 vs. 5) and the percentage of flail chest were higher in operatively treated patients (47% vs. 39%). CONCLUSION: It remains unknown to what extent conservative and operative treatment contribute individually to reducing morbidity and mortality in the elderly with multiple rib fractures. To date, the quality of evidence is rather low, thus well-performed comparative observational studies or randomised controlled trials considering all confounders are needed to determine whether operative treatment can improve a patient's outcome.

Treatment and outcome in combined scapula and rib fractures: a retrospective study.

PURPOSE: The primary aim was to describe the population characteristics of patients with combined scapula and rib fractures and outcomes associated with different treatment strategies. METHODS: All adult (≥ 18 years) patients with concurrent ipsilateral scapula and rib fractures admitted to the study hospital between 1st January 2010 and 31st June 2021 were retrospectively reviewed. RESULTS: A total of 223 patients were admitted with concurrent ipsilateral rib and scapula fractures. A total of 160 patients (72%) were treated conservatively, 63 patients (28%) operatively. Among operatively treated patients, 32 (51%) underwent rib fixation (RF) only, 24 (38%) underwent scapula fixation (SF) only, and seven patients (11%) underwent combined fixation of scapula and ribs (SRF). In general, more severely injured patients were treated with more extensive surgery. RF patients had a median hospital length of stay of 16 days, the SF patients 11 days and SRF patients 18 days. There were no significant differences in complications (pneumonia, recurrent pneumothorax and revision surgery) between groups. CONCLUSION: Injury severity resulted in different treatment modalities. As a result, different patient characteristics between treatment groups were observed, which makes direct comparison between treatment modalities impossible. All treatment modalities seem feasible; however, the additional value of both rib and scapula fixation has yet to be proven in large multicentre studies.

Surgical Rib Fixation of Multiple Rib Fractures and Flail Chest: A Systematic Review and Meta-analysis.

BACKGROUND: Multiple rib fractures and flail chest are common in trauma patients and may result in significant morbidity and mortality. While rib fractures have historically been treated conservatively, there is increasing interest in the benefits of surgical fixation. However, strong evidence that supports surgical rib fixation and identifies the most appropriate patients for its application is currently sparse. METHODS: A systematic review and meta-analysis following PRISMA guidelines was performed to identify all peer-reviewed papers that examined surgical compared to conservative management of rib fractures. We undertook a subgroup analysis to determine the specific effects of rib fracture type, age, the timing of fixation and study design on outcomes. The primary outcomes were the length of hospital and ICU stay, and secondary outcomes included mechanical ventilation time, rates of pneumonia, and mortality. RESULTS: Our search identified 45 papers in the systematic review, and 40 were included in the meta-analysis. There was a statistical benefit of surgical fixation compared to conservative management of rib fractures for length of ICU stay, mechanical ventilation, mortality, pneumonia, and tracheostomy. The subgroup analysis identified surgical fixation was most favorable for patients with flail chest and those who underwent surgical fixation within 72 h. Patients over 60 y had a statistical benefit of conservative management on length of hospital stay and mechanical ventilation. CONCLUSIONS: Surgical fixation of flail and multiple rib fractures is associated with a reduction in morbidity and mortality outcomes compared to conservative management. However, careful selection of patients is required for the appropriate application of surgical rib fixation.

The Impact of Seatbelt Use on Trauma Outcomes in Adult Motor Vehicle Collision Patients With Rib Fractures: A National ACS-TQP-PUF Database Analysis.

BACKGROUND: Motor vehicle collisions (MVCs) are a leading cause of morbidity and mortality. However, there is limited evidence examining the effects seatbelt use has on MVC-related injuries and outcomes in patients with rib fractures. We aim to assess how seatbelt use affects associated injuries and outcomes in adult MVC patients with ≥2 rib fractures. METHODS: This retrospective study utilized the American College of Surgeons (ACS) Trauma Quality Programs (TQP) Participant Use File (PUF) Database. Drivers/passengers who sustained ≥2 rib fractures following an MVC and had an AIS ≤2 for extra-thoracic body regions were analyzed. Patients were then subdivided by presence of flail chest into two cohorts, which were subdivided according to injury severity score (ISS) and seatbelt use. Logistic and linear regression was used to assess the impact of seatbelt use on outcomes. RESULTS: Among both low and intermediate ISS classifications, restrained patients in the non-flail chest cohort had decreased incidence of pneumothorax, pulmonary contusion, and liver injury (P < 0.001). After adjusting for confounders, restrained patients (versus unrestrained) had decreased odds of pneumothorax (aOR = 0.91, P = <0.001) and acute respiratory distress syndrome (aOR=0.65, P = 0.02), while having increased odds of splenic laceration (aOR = 1.18, P = 0.003) (intermediate ISS group). Compared to unrestrained patients, restrained non-flail chest patients had a significantly decreased hospital length of stay (LOS) and intensive care unit LOS (P < 0.05). CONCLUSIONS: Seatbelt use may be protective against serious injuries in patients with ≥2 rib fractures, resulting in improved outcomes. Education programs should be developed to bolster seatbelt compliance.

Surgical Rib Fixation in Obese Patients with Isolated Flail Chest Improves Outcomes: A Matched Cohort Study.

BACKGROUND: Obesity is associated with adverse outcomes after major operations. The role of operative rib fixation (RF) in obese patients with flail chest is not clear. The presence of other associated injuries may complicate the interpretation of outcomes. This study compared outcomes after RF to nonoperative management (NOM) in obese patients with isolated flail chest injury. METHODS: Adult obese patients (BMI > 29.9) with flail chest were identified from the Trauma Quality Improvement Program (TQIP) database (2016-2018). Hospital transfers, death within 72 h, and extrathoracic injuries were excluded. RF patients were propensity score matched (1:2) to similar NOM patients. Multivariate regression identified independent factors predicting adverse outcomes. RESULTS: Overall, 367 patients with isolated flail chest who underwent RF were matched with 734 in the NOM group. After matching, the mortality rate was significantly lower in the RF group (1.4% vs. 3.7%; p < 0.05). RF had longer HLOS (15.7 days vs. 12.8 days; p < 0.05) and ICU LOS (10.1 days vs. 8.6 days; p < 0.05), shorter ventilator days (9.2 days vs. 11.5 days; p < 0.05), and a higher rate of venous thromboembolism (7.1% vs. 3.5%, p < 0.05). On multivariate analysis, RF was associated with decreased mortality (OR 0.27; p < 0.05). Early RF (≤ 72 h) was associated with shorter ICU stay and mechanical ventilation. CONCLUSION: RF for isolated flail chest in obese patients is associated with decreased mortality and fewer ventilator days. When performed early, fixation decreases the need for prolonged ventilator use and ICU stay. A more aggressive VTE prophylaxis should be considered in patients undergoing RF.

Concomitant cardiac surgery and fixation of bilateral rib fractures sustained during cardiopulmonary resuscitation.

BACKGROUND: Chest compressions during cardiopulmonary resuscitation (CPR) may cause sternal or rib fractures and chest wall instability. This can complicate medical management and significantly impair respiratory function. Surgical management of flail chest is technically demanding, and it becomes even more challenging if the patient requires a concomitant cardiac procedure. CASE PRESENTATION: A 78-year-old male suffered a cardiac arrest and sustained sternal and bilateral rib fractures during a successful CPR. He underwent a concomitant coronary artery bypass grafting and aortic valve replacement combined with stabilization of the chest wall. We discuss the possibility of fixation of bilateral rib fractures and its role in postoperative recovery after cardiac surgery. CONCLUSIONS: Chest wall stabilization for an already fragile patient, with impaired respiratory system performance, could help improve overall outcomes, pulmonary function, weaning from mechanical ventilation, and rehabilitation. It may be used together with a cardiac procedure for a life-threatening cardiac pathology.

An innovative technique of chest wall stabilization and reconstruction in traumatic flail chest: The figure-of-eight suture with polypropylene mesh and musculofascial flap.

Surgical stabilization of the flail chest is challenging and has no established guidelines. Chest wall integrity and stability are the main factors that ensure the protection of intrathoracic organs and an adequate respiratory function. Here, we report a novel chest wall reconstruction technique in a 45-year-old man with a traumatic left flail chest and open pneumothorax diagnosed both clinically and radiographically. Rib approximation and chest wall reconstruction was done using intercostal figure-of-eight suture and polypropylene mesh with vascularized musculofascial flap. The patient improved gradually and was discharged after three weeks of total hospital stay. He returned to regular working after a month with no evidence of respiratory distress or paradoxical chest movement. Follow-up visit at one year revealed no lung hernia or paradoxical chest movement. This is a novel, feasible and cost-effective modification of chest wall reconstruction that can be adopted for thoracic wall repair in case of open flail chest, which needs emergency surgical interventions even in resource constraint settings.

Improved Fixation Stability of a Dedicated Rib Fixation System in Flail Chest: A Retrospective Study.

Background and Objectives: Flail chest typically results from major trauma to the thoracic cage and is accompanied by multiple rib fractures. It has been well documented that surgical fixation of rib fractures can decrease both morbidity and mortality rates. This study aimed to evaluate the effectiveness of a dedicated APS Rib Fixation System, which features a pre-contoured design based on anatomical rib data of the Asian population. Materials and Methods: We reviewed 43 consecutive patients, who underwent surgical stabilization for flail chest with the traditional Mini bone plate (n = 20), APS plate (n = 13), or Mini + APS (n = 10). Demographic and injury variables were documented. We used X-ray radiography to determine plate fractures and screw dislocations after surgical fixation. Results: No statistical differences were noted in the demographic or injury variables. APS plates demonstrated fewer cases of plate fractures and screw dislocations than Mini plates (OR = 0.091, p = 0.008). Conclusions: The pre-contoured design of the APS plate demonstrated a superior rib implant failure rate as compared to the traditional Mini bone plate. Our study indicates that the APS plate may serve as an effective surgical tool for the treatment of flail chest.

K-Rod: An Innovative Method of Personalized Rib Splinting for Expeditious Management of Flail Chest in Acute Care Settings.

Flail chest is a severe type of multiple rib fracture that can cause ventilation problems and respiratory complications. Historically, flail chest has been mainly managed through pain control and ventilatory support as needed. Operative fixation has recently become popular for the condition, and some studies have revealed its potentially positive effects on the outcomes of patients with flail chest. However, for those for whom surgery is unsuitable, few treatment options, other than simply providing analgesia, are available. Herein, we introduce our innovative method of applying personalized rib splinting for quick management of flail chest, which is easy, tailor-made, and has significant effects on pain reduction.

[Fixation of Flail Chest with Bioabsorbable Plate].

A 57-year-old man presented to our hospital with multiple rib fractures and pleural effusion caused by a traffic accident. We inserted a chest tube and diagnosed him with hemothorax. We performed damage control surgery with right thoracotomy in the emergency room to confirm the bleeding point. The main sources of bleeding were multiple rib fractures and lung injury. We performed partial lung resection and gauze packing into the thoracic cavity and confirmed the stability of the patient's hemodynamics. The next day, we performed a second-look operation at which we fixed the rib fractures and confirmed hemostasis. When fixing the ribs, we used a bioabsorbable plate instead of a metal plate. It has been reported that bioabsorbable plates are less susceptible to infection than metal plates. After the operation, the patient's respiratory condition stabilized, and no signs of infection were noted. In our experience, rib fixation using absorbent plates is useful in surgery that requires attention to infection.

[Chest Wall Injury].

A traumatic chest wall injury is a condition that is often encountered in medical practice, but the underlying pathophysiology varies widely depending on the circumstances of the injury and the patient's background. The chest wall, which protects vital organs and provides respiratory movement, can be a life-threatening emergency when injured, thus it is important to respond promptly and appropriately. Because a penetrating chest wall trauma is often associated with intra-thoracic organ damage, it is important to consider an emergency thoracotomy in cases involving massive hemorrhage or air leakage. The ribs and sternum are primarily injured in patients with blunt wall trauma. Flail chest, which is defined as multiple bifocal fractures of the ribs or multiple rib fractures with a sternal fracture, causes respiratory failure secondary to paradoxical respiration. The main treatment for flail chest is ventilatory care and surgical treatment, although early rib fixation has been reported to improve prognosis in recent years. There are several types of devices to fix the ribs and sternum, but selection criteria have yet to be established.

[Improvement in breathing mechanics by plate osteosynthesis of the ribs after cardiac massage : Case report and review of the literature]. / Verbesserung der Atemmechanik durch Plattenosteosynthese der Rippen nach Herzdruckmassage : Fallbericht und Literaturübersicht.

This article reports the case of a 69-year-old patient with multiple rib fractures and sternal fracture after repetitive cardiopulmonary resuscitation (CPR). Because of secondary respiratory failure due to an unstable thorax, rib fixation was performed 10 days after CPR. Subsequently, ventilation improved resulting in successful extubation 4 days after rib plating. A review of the literature revealed only five documented cases of rib osteosynthesis after CPR. Although flail chest occurs in up to 15% of patients after CPR, there is little evidence of the effect of rib fixation. The benefit of this procedure after chest trauma is reduced pain, shortened intensive care unit stay, lower rates of ventilation-associated pneumonia and lower costs for the healthcare system. Further clinical research is needed and interdisciplinary treatment should be kept in mind when dealing with patients resuscitated with prolonged mechanical ventilation.

Use of a pectus bar for surgical stabilization of cardiopulmonary resuscitation induced flail chest.

A flail chest can occur when cardiopulmonary resuscitation causes extensive rib fractures. Despite successful cardiopulmonary resuscitation, if the flail chest is not treated, the patient may not survive regardless of the correction of the primary condition that caused the cardiac arrest. Therefore, if flail chest persists despite the appropriate conservative management to correct the flail chest, active surgical management is essential. We present a successful surgical treatment with a pectus bar for a patient with flail chest, caused by extensive segmental rib fractures sustained during cardiopulmonary resuscitation for a massive pulmonary thromboembolism.

Combining the use of Nuss procedure and rib fixation for severe flail chest: a case report.

BACKGROUND: Severe flail chest is a life-threatening situation. The Nuss procedure is a new effective treatment for severe flail chest patients who cannot be weaned from prolonged mechanical ventilation in the last few years. However, the procedure is not suitable when there are multiple fractures in both the anterior and lateral chest walls. Here, we reported a rare case of severe flail chest in a patient who suffered multiple fractures in both the anterior and lateral chest walls in a traffic accident. CASE PRESENTATION: A 49-year-old patient suffered severe flail chest by a steering wheel in a traffic accident with multiple fractures in both the anterior and lateral chest walls. In the beginning, the patient was administrated with mechanical ventilation because of acute respiratory distress syndrome (ARDS) for more than 1 week. Then the patient suffered from a severe lung infection and decreased blood oxygen saturation. After a multidiscipline discussion (MDT), three rib fixation plates were first used to rebuild the stability of lateral chest walls, then two Nuss bars were inserted to eliminate paradoxical movement in the anterior chest wall. Finally, the patient recovered smoothly after the combining procedure. CONCLUSIONS: Severe flail chest patients with both the anterior and lateral chest walls after trauma are in a life-threatening situation, and require an appropriate procedure to get out of danger in time. Rib fixation is an effective treatment when the fractured sites are few and the fractured area is small. The Nuss procedure is a new effective method for severe flail chest with multiple fractures in an anterior chest wall, which is also a minimally invasive and short time-consuming procedure. However, it does not suitable for the patient with multiple fractures in lateral chest walls. Combining the use of Nuss procedure and rib fixation can solve severe flail chest with multiple ribs and sternum fractures in both the anterior and lateral chest walls, and the outcome of this procedure is satisfying in the present rare case.

Successful surgical treatment of Cronkhite-Canada Syndrome with bilateral flail chest: a case report.

BACKGROUND: Development of multiple rib fractures leading to bilateral flail chest in Cronkhite-Canada Syndrome (CCS) has not been reported. CASE PRESENTATION: A 59-year-old man presented with complaints of fatigue, chest pain, respiratory distress and orthopnea requiring ventilatory support to maintain oxygenation. CCS with bilateral anterior and posterior flail chest due to multiple rib fractures (2nd-10th on the right side and 2nd-11th on the left side). He underwent open reduction and anterior and posterior internal fixation using a titanium alloy fixator and a nickel-titanium memory alloy embracing fixator for chest wall reconstruction. He recovered gradually from the ventilator and showed improvement in his symptoms. He gained about 20 kg of weight in the follow up period (6 months after discharge from the hospital). CONCLUSION: CCS is a rare, complex disease that increases the risk of developing multiple rib fractures, which can be successfully treated with open reduction and internal fixation.

[Evolution of Opinions on Chest Wall Stabilisation and Our Experience]. / Vývoj názoru na stabilizace hrudní steny a nase zkusenosti.

PURPOSE OF THE STUDY Rib fractures represent one of the most common fractures sustained by 10-40% of all patients with blunt chest trauma, their incidence increases with age. In the current literature, however, new indication criteria continue to emerge. The purpose of this study is to assess the indication criteria, the timing of surgery and the use of individual plates in dependence on fracture location in our patients after the chest wall stabilisation in a retrospective analysis. MATERIAL AND METHODS Our group of patients (n = 349) included the patients who were hospitalised in the Trauma Centre of the University Hospital Olomouc from 1 January 2015 to 31 January 2019, of whom 16 patients were indicated for a surgery. In case of polytrauma, spiral CT was performed, while all patients with a more serious wall chest trauma underwent 3D CT chest wall reconstruction. The surgical approach was chosen based on the fracture location, most frequently posterolateral thoracotomy was opted for. The type of plates was chosen based on the location and type of the fracture. The most common was the lateral type of fracture. RESULTS The most common indication for surgery was multiple rib fractures with major chest wall disfiguration with the risk of injury to intrathoracic organs, present hemothorax or pneumothorax. The age of patients ranged from 44 to 92 years. 8 patients sustained a thoracic monotrauma, the remaining patients suffered multiple injuries, mostly craniocerebral trauma, pelvic or long bone fractures or parenchymal organ injury. The patients were indicated for surgery between 1 hour and 7 days after the hospital admission, on average 3 plates per patient were used and the most commonly used type of plate was the newly modified Judet plate made by Medin. All the patients underwent a surgical revision of pleural cavity, in 3 patients diaphragmatic rupture was found despite a negative preoperative CT scan. The duration of mechanical ventilation in polytrauma patients was 16 days, in thoracic monotrauma patients it was 2 days. CONCLUSIONS Prevailing majority of patients with a blunt chest trauma with rib fractures is still treated non-operatively, which is confirmed also by our group of patients. Nonetheless, correctly and early indicated stabilisation of the chest wall based on accurate indication criteria is of a great benefit to the patients. The aim of each and every trauma centre should be to develop a standardised protocol for the management of blunt chest trauma (the so-called "rib fracture protocol"), which comprises precisely defined criteria for patient admission, multimodal analgesia, indications for surgery, comprehensive perioperative and postoperative care and a subsequent rehabilitation of patients. Key words: rib fracture protocol, chest wall stabilisation, flail chest.

[Clinical Application and Mechanical Analysis of the Treatment of Multiple Rib Fractures and Flail Chest Using Three-wings Rib Plate].

This research evaluated the clinical efficacy of three-wings rib plate in the treatment of multiple rib fractures and flail chest with mechanical analysis and clinical verification. The model of rib and three-wings rib plate was reconstructed. The contact simulation with pretension stress was applied to the plate's fixation, and it was found that the bearable stress of the rib fractures after fixation increased from the result which indicated a good fixation efficacy of the plate. Clinical data of 53 cases of rib fractures and flail chest treated with three-wings rib plate in Shanghai Pudong Hospital of Fudan University were retrospectively analyzed. After the operation, the pain of the patients was relieved. Postoperative CT reconstruction of the chest showed good restoration of the rib fractures, which verified the clinical efficacy of three-wings rib plate. The three-wings rib plate showed a high value in clinical use for treatment of rib fractures.

A Statewide Assessment of Rib Fixation Patterns Reveals Missed Opportunities.

BACKGROUND: Rib fractures are a common consequence of traumatic injury and can result in significant debilitation. Rib fixation offers fracture stabilization, resulting in improved outcomes and decreased pulmonary complications, especially in high-risk groups such as those with flail segments. However, commercial rib fixation has only recently become clinically prevalent, and we hypothesize that significant variability exists in its utilization based on injury pattern and trauma center. METHODS: The Pennsylvania Trauma System Foundation database was queried for all multiple rib fracture patients occurring statewide in 2016 and 2017. Demographics including the presence of flail and the occurrence of rib fixation was abstracted. Outcomes were compared between the fixation group and all other rib fracture patients. Deidentified treating trauma center was used to elicit center-level disparities. RESULTS: During the study period, there were 12,910 patients with multiple rib fractures, of which 135 had flail segments. 57 patients underwent rib fixation, and 10 of which had a flail segment. Compared with the nonoperative cohort, those who underwent rib fixation were younger (52.5 versus 61.5, P = 0.0009), similar in gender (68% versus 62% male, P = 0.373), and race (80% versus 86% White, P = 0.239). The rib fixation group had higher Injury Severity Scores (19.4 versus 15.4 P = 0.0011). The timing of rib fixation was most frequent within 1 wk of injury but extended out through 3 wk; the occurrence of pulmonary complications had a similar distribution. The frequency of rib fixation rates within trauma centers was not associated with rib fracture patient volume, and 37.1% of multiple rib fracture patients were cared for at centers that did not perform rib fixation. CONCLUSIONS: Rib fixation is infrequently used at trauma centers in Pennsylvania. It is used more frequently in nonflail injuries, and its use may be associated with the occurrence of pulmonary complications. Significant center-level variation exists in rib fixation rates among multiple fractured patients. A significant number of patients are cared for at centers that do not perform rib fixation. Further research is needed to illicit better-defined indications for operative fixation, and opportunities exist to further the penetrance of this practice to all trauma centers.

A Randomized Controlled Trial of Surgical Rib Fixation in Polytrauma Patients With Flail Chest.

BACKGROUND: Flail chest (FC) is known to account for high mortality and morbidity and is typically treated with conservative care. Operative fixation of FC has been advocated as an alternative treatment choice. This prospective randomized controlled trial aims to compare surgical and nonsurgical management of FC in patients with severe polytrauma. METHODS: Severe polytrauma patients with FC admitted between January 2015 and July 2017 to our trauma center were investigated. The enrolled patients were randomly assigned to the surgical or nonsurgical group. Basic characteristics of injury and clinical outcomes were compared. RESULTS: Fifty patients entered final analysis, with 25 patients in each group. Operative rib fixation was associated with shorter duration of mechanical ventilation (7 d [interquartile range {IQR} 6-10] versus 9 d [IQR 7-12], P = 0.012), shorter ICU stay (10 d [IQR 7-12] versus 12 d [IQR 9-15], P = 0.032), lower risk of adult respiratory distress syndrome (28% versus 60%, P = 0.045), pneumonia (48% versus 80%, P = 0.038), and thoracic deformity (8% versus 36%, P = 0.037) and less pain while coughing (pain score 6 [IQR 3-8] versus 8 [IQR 4-9], P = 0.029) and deep breathing (pain score 5 [IQR 3-9] versus 7 [IQR 3-9], P = 0.038). Subgroup analysis was conducted by presence of pulmonary contusion. Shorter time on the ventilator use and ICU stay associated with rib surgery was not observed in patients with pulmonary contusion. CONCLUSIONS: This study reveals that surgical rib fixation may provide some critical care benefits for severe polytrauma patients with FC, including less medical resource use and lower risk of complications. Further studies should be designed to optimally identify patients who are most likely to benefit from this surgery.
