The efficacy of surgical stabilization of rib fracture (SSRF) in patients without flail chest has not been studied specifically. We hypothesized that SSRF improves outcomes among patients with ...displaced rib fractures in the absence of flail chest.
Multicenter, prospective, controlled, clinical trial (12 centers) comparing SSRF within 72 hours to medical management. Inclusion criteria were three or more ipsilateral, severely displaced rib fractures without flail chest. The trial involved both randomized and observational arms at patient discretion. The primary outcome was the numeric pain score (NPS) at 2-week follow-up. Narcotic consumption, spirometry, pulmonary function tests, pleural space complications (tube thoracostomy or surgery for retained hemothorax or empyema >24 hours from admission) and both overall and respiratory disability-related quality of life (RD-QoL) were also compared.
One hundred ten subjects were enrolled. There were no significant differences between subjects who selected randomization (n = 23) versus observation (n = 87); these groups were combined for all analyses. Of the 110 subjects, 51 (46.4%) underwent SSRF. There were no significant baseline differences between the operative and nonoperative groups. At 2-week follow-up, the NPS was significantly lower in the operative, as compared with the nonoperative group (2.9 vs. 4.5, p < 0.01), and RD-QoL was significantly improved (disability score, 21 vs. 25, p = 0.03). Narcotic consumption also trended toward being lower in the operative, as compared with the nonoperative group (0.5 vs. 1.2 narcotic equivalents, p = 0.05). During the index admission, pleural space complications were significantly lower in the operative, as compared with the nonoperative group (0% vs. 10.2%, p = 0.02).
In this clinical trial, SSRF performed within 72 hours improved the primary outcome of NPS at 2-week follow-up among patients with three or more displaced fractures in the absence of flail chest. These data support the role of SSRF in patients without flail chest.

Oral factor Xa (fXa) inhibitor-related bleeding is a concerning drug safety problem. There is considerable controversy surrounding available reversal strategies. The recently approved reversal agent ...andexanet alfa has limited data, an unclear safety profile, and imparts a substantial financial burden. This has led to the off-label use of four-factor prothrombin complex concentrates (4F-PCC) for this indication. This study aimed to assess the safety and efficacy of 4F-PCC for the management of major bleeding related to oral fXa inhibitors. This observational, retrospective study included adult patients admitted from 2014 to 2018 who received 4F-PCC (Kcentra
®
) for fXa inhibitor-related major bleeding. Efficacy was assessed using criteria described by Sarode et al. Secondary outcomes included the incidence of thromboembolism, mortality, and a cost analysis comparing 4F-PCC to andexanet alfa for reversal of oral fXa inhibitors. Thirty-one patients received 4F-PCC for major bleeding associated with apixaban (55%) or rivaroxaban (45%). Intracranial hemorrhage (58%) and pericardial effusion (16%) accounted for the majority of bleeding events. Most patients received a single weight-based 4F-PCC dose of 25 units/kg (38.7%) or 50 units/kg (51.6%). Effective hemostasis was achieved in 80.6% of patients. Five patients (16%) died due to acute bleeding and no thromboembolic events were observed. Administration of 4F-PCC was effective for most patients requiring emergent reversal of anticoagulation with apixaban or rivaroxaban and was associated with a low risk of thromboembolic events. Considerable cost differences limit the use of andexanet alfa and may warrant further study of 4F-PCC for fXa inhibitor reversal.
Sternal fractures are common following blunt traumatic injury. Most sternal fractures can be managed successfully nonoperatively; however, surgical fixation should be considered in certain scenarios. ...Specifically, surgery may be indicated in cases of severe pain, respiratory failure or dependency on mechanical ventilation, cosmetic deformity, malunion, disunion, and compression of the heart. A variety of surgical approaches to sternal fracture fixation have been documented (steel wire, suture materials, a seven-hole aluminum plate, an eight-holed Sternolock X plate, sternum-osteosynthesis plate, t-shaped plate); however, few techniques have been discussed for the initial reduction of the sternal fracture prior to fixation. In this paper, we describe a novel surgical technique used to reduce sternal fractures and approximate the edges of the sternum using a compression/distraction device.
In 2019, we sought to develop a chest wall injury and reconstruction clinic (CWIRC) to treat patients with chest wall pain and rib fractures. This initiative was fueled by the recognition of an unmet ...need and evolving research demonstrating improved patient care and experience. We will describe the evolution of this clinic program from an acute care surgery/general surgery (ACS/GS) clinic to a CWIRC.
We identified outpatient encounters generated from a general surgery clinic staffed by a physician and nurse practitioner team. A retrospective cohort review was performed to identify all outpatient encounters and surgeries associated with these encounters from January 1, 2017, to November 30, 2021. Outpatient and operative work relative value unit (wRVU) production as well as payer mix was compared as the primary outcome.
Over this time period, the number of clinic interactions decreased (2017-284 vs. 2021-229). Clinic productivity increased however from 181 wRVUs in 2017 to 295 wRVUs in 2021. The CWIRC patient visits increased from 4% to 70%. In addition, telehealth visits increased from 0% to 23% of encounters. The operative wRVU productivity attributable to outpatient clinic visits increased (2017-253 vs. 2021-591). Combined, the CWIRC resulted in an overall growth of 104% in total wRVUs. The payer mixes for patients with rib diagnosis have a higher number of Blue Cross Blue Shield, Medicare, and Managed Care compared with ACS/GS. The most common diagnosis was rib fracture initial evaluation (37%), rib fracture subsequent encounter (25%), rib pain (24%), and flail chest initial evaluation (4%).
The initiation of a CWIRC increased wRVU production despite a decrease in clinical encounters. These clinics may produce more wRVUs per encounter than ACS/GS clinics. An underserved population has been identified of chest wall pathology patients presenting for initial evaluation as outpatients. Further investigation into this concept is warranted to serve this population.
Therapeutic/Care Management; Level IV.
Background:
Rib fractures account for more than one-third of blunt thoracic injuries and are associated with serious complications. Use of nonopioid adjunctive agents such as methocarbamol for pain ...control has increased considerably.
Objective:
This study aimed to assess the impact of methocarbamol addition to the pain control regimen on daily opioid requirements for young adults with rib fractures.
Methods:
This observational, retrospective study included patients aged 18 to 39 years with 3 or more rib fractures who were admitted to a level 1 trauma center between July 2014 and July 2018. Patients were dichotomized based on admission before and after methocarbamol addition to the institutional rib fracture protocol. The primary outcome was to determine the impact of methocarbamol on daily opioid requirements. Secondary outcomes included hospital length of stay (LOS) and diagnosis of pneumonia.
Results:
A total of 50 patients were included, with 22 and 28 patients in the preprotocol and postprotocol groups, respectively. All patients in the latter group received methocarbamol, whereas no patient in the preprotocol group received methocarbamol. Cumulative opioid exposure was significantly less for patients admitted after methocarbamol addition to the protocol (219 vs 337 mg oral morphine equivalents; P = 0.01), and hospital LOS was also decreased (4 vs 3 days; P = 0.03). No significant differences in the incidence of pneumonia or adverse effects were observed.
Conclusion and Relevance:
This is the first study to evaluate the impact of methocarbamol on reducing opioid requirements. Given the risks associated with opioids, use of methocarbamol as an analgesia-optimizing, opioid-sparing multimodal agent may be reasonable.
Cardiopulmonary resuscitation (CPR) contributes to significant chest wall injury similar to blunt trauma. With benefits realized for surgical stabilization of rib fractures (SSRFs) for flail injuries ...and severely displaced fractures following trauma, SSRF for chest wall injury following CPR could be advantageous, provided good functional and neurologic outlook. Experience is limited. We present a review of patients treated with SSRF at our institution following CPR.
A retrospective analysis of patients undergoing SSRF following CPR was performed between 2019 and 2020. Perioperative inpatient data were collected with outpatient follow-up as able.
Five patients underwent SSRF over the course of the 2-year interval. All patients required invasive ventilation preoperatively or had impending respiratory. Mean age was 59 ± 12 years, with all patients being male. Inciting events for cardiac arrest included respiratory, ventricular tachycardia, ventricular fibrillation, pulseless electrical activity, and anaphylaxis. Time to operation was 6.6 ± 3 days. Four patients demonstrated anterior flail injury pattern with or without sternal fracture, with one patient having multiple severely displaced fractures. Surgical stabilization of rib fracture was performed appropriately to restore chest wall stability. Mean intensive care unit length of stay was 9.8 ± 6.4 days and overall hospital length of stay 24.6 ± 13.2 days. Median postoperative ventilation was 2 days (range, 1-15 days) with two patients developing pneumonia and one requiring tracheostomy. There were no mortalities at 30 days. One patient expired in hospice after a prolonged hospitalization. Disposition destination was variable. No hardware complications were noted on outpatient follow-up, and all surviving patients were home.
Chest wall injuries are incurred frequently following CPR. Surgical stabilization of these injuries can be considered to promote ventilator liberation and rehabilitation. Careful patient selection is paramount, with surgery offered to those with reversible causes of arrest and good functional and neurologic outcome. Experience is early, with further investigation needed.

Historically, hemorrhage has been attributed as the leading cause (40%) of early death. However, a rigorous, real-time classification of the cause of death (COD) has not been performed. This study ...sought to prospectively adjudicate and classify COD to determine the epidemiology of trauma mortality.
Eighteen trauma centers prospectively enrolled all adult trauma patients at the time of death during December 2015 to August 2017. Immediately following death, attending providers adjudicated the primary and contributing secondary COD using standardized definitions. Data were confirmed by autopsies, if performed.
One thousand five hundred thirty-six patients were enrolled with a median age of 55 years (interquartile range, 32-75 years), 74.5% were male. Penetrating mechanism (n = 412) patients were younger (32 vs. 64, p < 0.0001) and more likely to be male (86.7% vs. 69.9%, p < 0.0001). Falls were the most common mechanism of injury (26.6%), with gunshot wounds second (24.3%). The most common overall primary COD was traumatic brain injury (TBI) (45%), followed by exsanguination (23%). Traumatic brain injury was nonsurvivable in 82.2% of cases. Blunt patients were more likely to have TBI (47.8% vs. 37.4%, p < 0.0001) and penetrating patients exsanguination (51.7% vs. 12.5%, p < 0.0001) as the primary COD. Exsanguination was the predominant prehospital (44.7%) and early COD (39.1%) with TBI as the most common later. Penetrating mechanism patients died earlier with 80.1% on day 0 (vs. 38.5%, p < 0.0001). Most deaths were deemed disease-related (69.3%), rather than by limitation of further aggressive care (30.7%). Hemorrhage was a contributing cause to 38.8% of deaths that occurred due to withdrawal of care.
Exsanguination remains the predominant early primary COD with TBI accounting for most deaths at later time points. Timing and primary COD vary significantly by mechanism. Contemporaneous adjudication of COD is essential to elucidate the true understanding of patient outcome, center performance, and future research.

Subclavian and axillary artery injuries are uncommon. In addition to many open vascular repairs, endovascular techniques are used for definitive repair or vascular control of these anatomically ...challenging injuries. The aim of this study was to determine the relative roles of endovascular and open techniques in the management of subclavian and axillary artery injuries comparing hospital outcomes, and long-term limb viability.
A multicenter, retrospective review of patients with subclavian or axillary artery injuries from January 1, 2004, to December 31, 2014, was completed at 11 participating Western Trauma Association institutions. Statistical analysis included χ, t-tests, and Cochran-Armitage trend tests. A p value less than 0.05 was significant.
Two hundred twenty-three patients were included; mean age was 36 years, 84% were men. An increase in computed tomography angiography and decrease in conventional angiography was observed over time (p = 0.018). There were 120 subclavian and 119 axillary artery injuries. Procedure type was associated with injury grade (p < 0.001). Open operations were performed in 135 (61%) patients, including 93% of greater than 50% circumference lacerations and 83% of vessel transections. Endovascular repairs were performed in 38 (17%) patients; most frequently for pseudoaneurysms. Fourteen (6%) patients underwent a hybrid procedure. Use of endovascular versus open procedures did not increase over the duration of the study (p = 0.248). In-hospital mortality rate was 10%. Graft or stent thrombosis occurred in 7% and graft or stent infection occurred in 3% of patients. Mean follow-up was 1.6 ± 2.4 years (n = 150). Limb salvage was achieved in 216 (97%) patients.
The management of subclavian and axillary artery injuries still requires a wide variety of open exposures and procedures, especially for the control of active hemorrhage from more than 50% vessel lacerations and transections. Endovascular repairs were used most often for pseudoaneurysms. Low early complication rates and limb salvage rates of 97% were observed after open and endovascular repairs.
Prognostic/epidemiologic, level IV.
Four-factor prothrombin complex concentrate (4F-PCC) is standard of care for emergent vitamin K antagonist (VKA) reversal but optimal dosing is uncertain. This meta-analysis estimated the proportion ...of patients treated with fixed dose (FD) 4F-PCC who achieved adequate reversal and compared safety and efficacy of FD versus weight-based dose (WB) strategies.
This review was conducted according to PRISMA guidelines. Medline and Scopus were searched and included studies evaluating FD regimens and comparing FD and WB for emergent VKA reversal. Data was pooled using random effects. Subgroup analyses examined heterogeneity. Risk of bias was assessed with Newcastle-Ottawa Scale and RoB2 score.
Twenty-three studies (n = 2055) were included with twelve (n = 1143) comparing FD versus WB. The proportion of patients achieving goal INR with FD varied depending on the INR target, being significantly higher for INR <2 (90.9%, 95% Confidence Interval (CI) 87.2, 94.06) compared to INR <1.6 (70.97%, 95%CI 65.33, 76.31). Compared to WB, FD was less likely to achieve a goal INR <1.6 (Risk Difference (RD) −13%, 95% CI −21, −4) but achieved similar reversal for a goal INR <2.0, (RD −1%, 95%CI −7, 4). There was no difference in hospital mortality (RD 4%, 95%CI −2, 9) or thrombosis (RD 0.0%, 95%CI −3, 3).
FD VKA reversal was associated with significantly lower attainment of goal INR compared to WB with lower INR targets. This did not translate to differences in hospital mortality, but these results should be interpreted cautiously in light of the observational nature of the included studies.
•Optimal dosing of four-factor prothrombin complex concentrate (4F-PCC) for vitamin K antagonist reversal is uncertain.•Emerging interest in fixed dose 4F-PCC is due to potential decreased risk of thrombosis and cost.•When compared to variable dose 4F-PCC, fixed dose may decrease the attainment of goal INR.•This decrease did not translate to differences in patient centered outcomes between dosing schema.
