RESUMO

PURPOSE: Predominant or isolated spasticity of the triceps following upper motor neuron injury is rare and often unmasked once the spastic elbow flexors are addressed. The purpose of this study was to delineate the motor branching pattern of the radial nerve to determine the feasibility of hyperselective neurectomies (HSN) for triceps spasticity. METHODS: Dissections of the motor branch to each triceps head were performed on 11 upper-extremity specimens. The numbers of trunks, branching patterns, and muscle entry points were recorded in reference to the acromion to interepicondylar line. Based on anatomic studies, 10 patients underwent a combined fractional lengthening and HSN procedure for triceps spasticity. Patient demographics, time from diagnosis, and complications were recorded. Preoperative and postoperative Modified Ashworth Scale (MAS) and total active elbow arc of motion were compared. RESULTS: The first branch from the radial nerve was consistently a single trunk to the long triceps head. There were many variations in the branching pattern and number of trunks to the lateral and medial heads of the triceps with motor entry points between 31% and 95% of the acromion to interepicondylar line distance. Ten patients (six men and four women; mean age: 48.5 years) underwent the combined procedure. Mean total active elbow arc of motion improved from 78° before surgery to 111° after surgery, with a 17.5° increase in active elbow flexion. Compared with a mean preoperative triceps MAS of 2.75, nine patients had triceps MAS of 0 at a mean of 10.2 months of follow-up. There was no loss of functional elbow extension and no directly related complications. CONCLUSIONS: Given the variable motor entry points, HSN to each triceps head would require extensive dissection. Therefore, a combined approach consisting of fractional lengthening of the long head and lateral head with HSN of the triceps medial head is recommended to address triceps spasticity. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic V.

RESUMO

PURPOSE: To review the existing literature to (1) determine the diagnostic efficacy of artificial intelligence (AI) models for detecting scaphoid and distal radius fractures and (2) compare the efficacy to human clinical experts. METHODS: PubMed, OVID/Medline, and Cochrane libraries were queried for studies investigating the development, validation, and analysis of AI for the detection of scaphoid or distal radius fractures. Data regarding study design, AI model development and architecture, prediction accuracy/area under the receiver operator characteristic curve (AUROC), and imaging modalities were recorded. RESULTS: A total of 21 studies were identified, of which 12 (57.1%) used AI to detect fractures of the distal radius, and nine (42.9%) used AI to detect fractures of the scaphoid. AI models demonstrated good diagnostic performance on average, with AUROC values ranging from 0.77 to 0.96 for scaphoid fractures and from 0.90 to 0.99 for distal radius fractures. Accuracy of AI models ranged between 72.0% to 90.3% and 89.0% to 98.0% for scaphoid and distal radius fractures, respectively. When compared to clinical experts, 13 of 14 (92.9%) studies reported that AI models demonstrated comparable or better performance. The type of fracture influenced model performance, with worse overall performance on occult scaphoid fractures; however, models trained specifically on occult fractures demonstrated substantially improved performance when compared to humans. CONCLUSIONS: AI models demonstrated excellent performance for detecting scaphoid and distal radius fractures, with the majority demonstrating comparable or better performance compared with human experts. Worse performance was demonstrated on occult fractures. However, when trained specifically on difficult fracture patterns, AI models demonstrated improved performance. CLINICAL RELEVANCE: AI models can help detect commonly missed occult fractures while enhancing workflow efficiency for distal radius and scaphoid fracture diagnoses. As performance varies based on fracture type, future studies focused on wrist fracture detection should clearly define whether the goal is to (1) identify difficult-to-detect fractures or (2) improve workflow efficiency by assisting in routine tasks.

RESUMO

PURPOSE: The aim of this prospective, randomized, controlled, double-blinded pilot study was to determine the rates of post-traumatic osteoarthritis and assess joint space width in the presence or absence of a single intra-articular injection of corticosteroid after an acute, intra-articular distal radius fracture (DRF). METHODS: Forty patients received a single, intra-articular, radiocarpal joint injection of 4 mg of dexamethasone (DEX) (n = 19) or normal saline placebo (n = 21) within 2 weeks of a surgically or nonsurgically treated intra-articular DRF. The primary outcome measure was minimum radiocarpal joint space width (mJSW) on noncontrast computed tomography scans at 2 years postinjection. Secondary outcomes were obtained at 3 months, 6 months, 1 year, and 2 years postinjection and included Disabilities of the Arm, Shoulder, and Hand; Michigan Hand Questionnaire; Patient-Rated Wrist Evaluation; wrist range of motion; and grip strength. RESULTS: At 2-year follow-up, there was no difference in mean mJSW between the DEX group (2.2 mm; standard deviation, 0.6; range, 1.4-3.2) and the placebo group (2.3 mm; standard deviation, 0.7; range, 0.9-3.9). Further, there were no differences in any secondary outcome measures at any postinjection follow-up interval. CONCLUSIONS: Radiocarpal joint injection of corticosteroid within 2 weeks of an intra-articular DRF does not appear to affect the development of post-traumatic osteoarthritis within 2 years follow-up in a small pilot cohort. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic II.

RESUMO

The thumb-in-palm (TIP) deformity in adults with upper motor neuron syndrome results from an imbalance of extrinsic and intrinsic muscular forces. Traditionally, the thumb is adducted against the index ray, and flexed to varying degrees at the metacarpophalangeal and interphalangeal joints. However, not all TIP deformities result from the same underlying imbalances. The severity of the deformity ranges over a spectrum dependent upon the involved muscle groups and underlying spasticity, myostatic contracture, and/or joint contractures. Surgical procedures for correcting a TIP deformity can be classified broadly as procedures used for functional, present volitional motor control, versus nonfunctional, absent motor control. Techniques include tenotomies, tenodeses, tendon lengthenings, tendon transfers, tendon reroutings, neurectomies, and joint releases. A focused physical examination is key in developing a patient-specific treatment algorithm.

RESUMO

PURPOSE: In response to the COVID-19 pandemic, many postgraduate medical education lectures and conferences have been moved to a virtual platform. Questions remain regarding the effectiveness of virtual education, what types of educational offerings can be transitioned to a virtual format, and what types of curricula should still take place in person. METHODS: This study surveyed trainees from the United States who participated in a single institution's hand surgery virtual flipped classroom curriculum of 6 week-long modules. Demographics, premodule and postmodule achieved levels of learning based on Bloom's taxonomy, technology usage, and preferences were surveyed. RESULTS: Of the 65 participants, 41 (63.1%) responded to the survey. Trainees included hand surgery fellows (27/41 [65.9%]), orthopedic surgery residents (11/41[26.8%]), and plastic surgery residents (3/41 [7.3%]). On average, most trainees read, viewed, and participated in more than half of the articles (28/41 [68.3%]), electronic videos (31/41 [75.6%]), and conferences (35/41 [85.4%]) per week. The median level of achieved learning increased from "I can apply" to "I can analyze" for all modules. Self-directed learning was preferred for basic facts and knowledge (26/41 [63.4%]) and faculty-directed learning was preferred to review and practice advanced concepts (34/41 [82.9%]). The participants perceived benefits of the virtual curriculum to include increased scheduling flexibility (8/41[19.5%]), expert opinions (7/41 [17.1%]), and diversity of educational formats (3/41 [7.3%]). The perceived drawbacks included decreased interaction (8/41 [19.5%]), technical difficulties (6/41 [14.6%]), excessive detail (3/41 [7.3%]), and single-institution bias (2/41 [4.9%]). CONCLUSIONS: The flipped virtual classroom model is an effective and preferred method of instruction for trainees. Trainees achieved a higher level of learning following the completion of each week-long module. Considerations for the implementation of a virtual curriculum include content quality, quantity, and reducing single-institution bias. CLINICAL RELEVANCE: The implementation of virtual learning can enhance hand surgery education for the modern learner.

RESUMO

Spastic shoulder deformity in patients with upper motor neuron syndrome results from an imbalance of muscle forces about the shoulder girdle. In typical spastic deformities, the shoulder assumes an adducted and internally rotated posture. The severity of the deformity can range over a spectrum depending on the involved muscle groups, degree of spasticity, and presence of myostatic and/or joint contractures. Surgical options to correct the spastic shoulder deformity can be broadly classified as procedures for the functional versus nonfunctional shoulder or, in other words, preserved versus absent volitional motor control, respectively. Techniques include tenotomy, fractional lengthening, tenodesis, and periarticular soft tissue release. A focused physical examination is imperative in developing a patient-specific treatment algorithm.

RESUMO

PURPOSE: To survey current hand surgery fellows on the perceived impact of residents on their fellowship educational experience. METHODS: Electronic surveys were distributed to 177 hand surgery fellows in the United States. The survey was designed to elucidate details of their fellowship programs, percentage of time working with, and in competition with, residents in differing clinical settings, perception of the impact of residents on their education, and strategies for resolving conflicts with attending physicians and residents. RESULTS: Of the 177 hand surgery fellows, 72 (40.1%) responded to the survey, of which 61 (84.7%) were orthopedic surgery-trained, 11 (15.3%) were plastic surgery-trained, and 0 (0%) were general surgery-trained. As fellows, 56 (78%) respondents reported working alongside a dedicated resident on their service. The median percentage of time spent working with the residents was 50% or higher for all clinical environments. The median perceived percentage time in competition with residents was 25% in the operating room and 0% for all other clinical environments. Fifty-one (71%) respondents agreed or strongly agreed that residents enhanced their educational experience, and 55 (76%) respondents stated that these interactions will positively or somewhat positively affect their abilities to practice as a future hand surgeon. A plurality of fellows reported that they resolved conflicts cooperatively with residents (n = 34, 47.2%) and that this was their preference (n = 36, 50.0%). The majority of fellows were comfortable with discussing educational conflicts with their attending and/or program director (n = 67, 93.1%). CONCLUSIONS: Hand surgery fellows frequently work with residents. The operating room is the most frequent site for competition between fellows and residents. Fellows responded positively when asked if residents should be involved in their fellowship. When conflicts do arise, fellows have the skills to manage conflicts with residents collaboratively. CLINICAL RELEVANCE: This study evaluates the relationship between residents and fellows to improve the postgraduate educational experience.

RESUMO

INTRODUCTION: Using direct peritoneal resuscitation (DPR) as an adjunct when managing patients undergoing damage control laparotomy (DCL) shows promising results. We report our initial experience in utilizing DPR when managing patients who underwent DCL for emergent surgery at the index operation. MATERIALS AND METHODS: We prospectively collected data on 37 patients between August 2020 to October 2021 who underwent DCL with open abdomens after the index operation and utilized DPR. DPR was performed using peritoneal lavage with DIANEAL PD-2-D 2.5% Ca 3.5 mEq/L at a rate of 400ml/hour. Patients' physiological scores and clinical outcomes were evaluated. RESULTS: 86% required DCL and DPR due to septic abdomen/bowel ischemia. The median (interquartile range [IQR]) age was 62 years (53-70); 62% were male, and median (IQR) body mass index was 30.0kg/m2 (25.5-38.4). On DPR initiation, median (IQR) APACHE-IV score was 48 (33-64) and median (IQR) Acute Physiology Score (APS) was 31 (18-54). After initiation, median (IQR) APACHE-IV score and median (IQR) APS were 39 (21-62) and 19 (11-56), respectively, and both showed significant improvement in survivors (p<0.05). Median (IQR) DPR duration was four days (2-8) and primary abdominal closure was achieved in 30 patients (81%). There were eight mortalities (21.6%) within 30 days postoperatively, of which seven were within 3-24 days due to uncontrolled sepsis/multiple organ failure. The most frequent complication was surgical-site infection recorded in 12 patients (32%). Twenty-four patients (67%) were discharged home/transferred to a rehab center/nursing home. CONCLUSION: DPR application showed significant improvement of APACHE-IV score and APS in patients with peritonitis/septic abdomen.

RESUMO

BACKGROUND: Efficient Emergency Department (ED) throughput depends on several factors, including collaboration and consultation with surgical services. The acute care surgery service (ACS) collaborated with ED to implement a new process termed "FASTPASS" (FP), which might improve patient-care for those with acute appendicitis and gallbladder disease. The aim of this study was to evaluate the 1-year outcome of FP. METHODS: FASTPASS is a joint collaboration between ACS and ED. ED physicians were provided with a simple check-list for diagnosing young males (<50-year old) with acute appendicitis (AA) and young males or females (<50-year old) with gallbladder disease (GBD). Once ED deemed patients fit our FP check-list, patients were directly admitted (FASTPASSed) to the observation unit. The ACS then came to evaluate the patients for possible surgical intervention. We performed outcome analysis before and after the institution of the FP. Outcomes of interest were ED length of stay (LOS), time from ED to the operating room (OR) (door-to-knife), hospital LOS (HLOS), and cost. RESULTS: During our 1-year study period, for those patients who underwent GBD/AA surgery, 56 (26%) GBD and 27 (26%) AA patients met FP criteria. Compared to the non-FP patients during FP period, FP halved ED LOS for GBD (7.4 ± 3.0 versus 3.5 ± 1.7 h, P < 0.001) and AA (6.7 ± 3.3 versus. 1.8 ± 1.6 h, P < 0.001). Similar outcome benefits were observed for door-to-knife time, HLOS, and costs. CONCLUSIONS: In this study, the FP process improved ED throughput in a single, highly-trained ER leading to an overall improved patient care process. A future study involving multiple EDs and different disease processes may help decrease ED overcrowding and improve healthcare system efficiency.

RESUMO

INTRODUCTION: Traditional management of traumatic hemothorax/hemopneumothorax (HTX/HPTX) has been insertion of large-bore 32-40 French (Fr) chest tubes (CTs). Retrospective studies have shown 14Fr percutaneous pigtail catheters (PCs) are equally effective as CTs. Our aim was to compare effectiveness between PCs and CTs by performing the first randomized controlled trial (RCT). We hypothesize PCs work equally as well as CTs in management of traumatic HTX/HPTX. METHODS: Prospective RCT comparing 14Fr PCs to 28-32Fr CTs for management of traumatic HTX/HPTX from 07/2015 to 01/2018. We excluded patients requiring emergency tube placement or who refused. Primary outcome was failure rate defined as retained HTX or recurrent PTX requiring additional intervention. Secondary outcomes included initial output (IO), tube days and insertion perception experience (IPE) score on a scale of 1-5 (1 = tolerable experience, 5 = worst experience). Unpaired Student's t-test, chi-square and Wilcoxon rank-sum test were utilized with significance set at P < 0.05. RESULTS: Forty-three patients were enrolled. Baseline characteristics between PC patients (N = 20) and CT patients (N = 23) were similar. Failure rates (10% PCs vs. 17% CTs, P = 0.49) between cohorts were similar. IO (median, 650 milliliters[ml]; interquartile range[IR], 375-1087; for PCs vs. 400 ml; IR, 240-700; for CTs, P = 0.06), and tube duration was similar, but PC patients reported lower IPE scores (median, 1, "I can tolerate it"; IR, 1-2) than CT patients (median, 3, "It was a bad experience"; IR, 3-4, P = 0.001). CONCLUSION: In patients with traumatic HTX/HPTX, 14Fr PCs were equally as effective as 28-32Fr CTs with no significant difference in failure rates. PC patients, however, reported a better insertion experience. www.ClinicalTrials.gov Registration ID: NCT02553434.

RESUMO

BACKGROUND: To analyze and report on the changes in epidemiology traumatic causes of death in the USA. METHODS: Data were extracted from the annual National Vital Statistics Reports (2008-2017) from Center for Disease Control and analyzed for trends during the time period given. Generalized additive model was applied to evaluate the significance of trend using R software. RESULTS: Firearm deaths (39,790) and firearm death rate (12.2/100,000) in 2017 were the highest reported, and this increasing trend was significant (p < 0.001) the last ten years. Deaths from motor vehicle crash (MVC) and firearm homicides did not change significantly during the same time period. Firearm deaths were lower than MVC deaths by 21% (8,197/39,790) in 2008, but after 10 years, the difference was only 1% (458/40,231). Years of life lost from firearms is now higher than MVC. Suicides by firearm in 2017 were the highest reported at 23,854/39,773 (60%). In 2017, suicides by firearm victims were predominantly white 20,328/23,562 (85%), men 20,362/23,562 (86%), and the largest group was between the ages of 55-64. CONCLUSIONS: Death from firearms in the USA is increasing and endemic. They were the highest ever reported in 2017 by the CDC. While deaths from MVC used to be the main cause of traumatic death in the USA, deaths from firearms now almost equal it. Calculated years of life lost from firearms is now more than from MVC. Most firearm deaths are not from homicides but are from suicides, and they are predominantly in white older males of the baby boomer generation (born 1946-1964).

RESUMO

Accumulating evidence suggests that α-synuclein (α-syn) occurs physiologically as a helically folded tetramer that resists aggregation. However, the mechanisms underlying the regulation of formation of α-syn tetramers are still mostly unknown. Cellular membrane lipids are thought to play an important role in the regulation of α-syn tetramer formation. Since glucocerebrosidase 1 (GBA1) deficiency contributes to the aggregation of α-syn and leads to changes in neuronal glycosphingolipids (GSLs) including gangliosides, we hypothesized that GBA1 deficiency may affect the formation of α-syn tetramers. Here, we show that accumulation of GSLs due to GBA1 deficiency decreases α-syn tetramers and related multimers and increases α-syn monomers in CRISPR-GBA1 knockout (KO) SH-SY5Y cells. Moreover, α-syn tetramers and related multimers are decreased in N370S GBA1 Parkinson's disease (PD) induced pluripotent stem cell (iPSC)-derived human dopaminergic (hDA) neurons and murine neurons carrying the heterozygous L444P GBA1 mutation. Treatment with miglustat to reduce GSL accumulation and overexpression of GBA1 to augment GBA1 activity reverse the destabilization of α-syn tetramers and protect against α-syn preformed fibril-induced toxicity in hDA neurons. Taken together, these studies provide mechanistic insights into how GBA1 regulates the transition from monomeric α-syn to α-syn tetramers and multimers and suggest unique therapeutic opportunities for PD and dementia with Lewy bodies.

RESUMO

PURPOSE: Tendon-to-tendon attachment constructs for tendon reconstructions or transfers need to be secure in order to allow early mobilization after surgery. The purpose of this study was to biomechanically compare 2 common constructs secured with a novel mesh suture versus a nonabsorbable braided suture. METHODS: We used 100 cadaveric tendons to create 5 different tendon coaptation constructs (a to e) (10 coaptations per group): (a) Pulvertaft weave with a braided suture (PTe); (b) mesh suture (PTm); (c) single-pass, side-to-side (SP-STS) coaptation with 30-mm overlap using a mesh suture (SP-STS-30m); (d) SP-STS 50-mm overlap with a mesh suture (SP-STS-50m); and (e) SP-STS with 30-mm tendon overlap using a braided suture (SP-STS-30e). The tensile strength, bulk, gliding resistance, and failure type were compared. RESULTS: There was no difference between the various tendon constructs and the suture type in terms of coaptation bulk. All SP-STS constructs with mesh suture had higher peak gliding resistance than any of the PT constructs regardless of suture type. Compared with the PT constructs, the SP-STS constructs with mesh or braided suture had a higher peak load, peak load normalized to repair length, and stiffness. Within each tendon coaptation construct group, Pulvertaft or SP-STS, the suture type did not affect any of the investigated parameters. CONCLUSIONS: The SP-STS constructs are significantly stronger and stiffer than the PT constructs. The SP-STS with mesh suture exhibited greater gliding resistance than the PT constructs and may result in greater gliding resistance through physiological tissue planes. However, the use of a mesh suture did not affect strength, bulk, gliding resistance, or failure type when compared within a construct group. CLINICAL RELEVANCE: The use of SP-STS constructs for tendon coaptations produces a stronger and stiffer construct than the PT weave; however, the use of a mesh suture may not provide any benefit over a braided suture.

RESUMO

Transradial amputation is a reconstructive option for upper-extremity trauma, infection, malignancy, and ischemia. The possible postoperative complications include residual radioulnar impingement and the development of a painful neuroma. In this report, a pedicled pronator quadratus flap interposition between the distal radius and ulna has been described. Additionally, various techniques to mitigate the development of symptomatic neuromas have been described.

RESUMO

INTRODUCTION: Traumatic abdominal wall hernias (TAWHs) after blunt trauma, while rare, are typically associated with severe injuries, particularly those involved with the seatbelt triad of abdominal wall disruption. The aim of this study is to present a case series of patients with TAWHs that were managed at an early stage post injury with a biological mesh. MATERIALS AND METHODS: Patients with TAWH undergoing complex abdominal wall reconstruction (CAWR) between 2017 and 2020 were identified from our institutional database. All patients underwent definitive reconstruction using advanced surgical techniques including a posterior component separation with biological mesh (STRATTICE™, Allergan, Inc., Dublin, Ireland) placed in a sublay fashion. RESULTS: Seven patients underwent definitive TAWH repair during their index admission: the median age was 56 years (range 20-77) and the median Injury Severity Score (ISS) was 34 (29-50). The most common mechanism of injury was motor vehicle crash (MVC) at 86%, while the most common intra-abdominal concomitant injury was small bowel. Traumatic hernia location was on the right side of the abdominal wall in three patients, left in three patients, and bilaterally in one patient. There were no hernia recurrences or deaths in this small cohort. CONCLUSION: Traumatic abdominal wall disruption can be safely reconstructed using advanced surgical techniques with a biological mesh during the acute phase or same index hospitalization.

RESUMO

Injury to the central nervous system can create upper extremity deformities and dysfunction, typically caused by a cerebrovascular accident, traumatic brain injury, anoxic brain injury, or spinal cord injury. Regardless of the etiology, disruption of inhibitory upper motor neuron (UMN) pathways can lead to a constellation of symptoms such as muscle weakness, decreased motor control, hyperexcitable tendon reflexes, muscle spasticity, and agonist-antagonist cocontraction that characterizes a condition known as UMN syndrome. The magnitude of neurorecovery varies among patients who have sustained brain injuries and can be classified as having a functional or nonfunctional upper extremity based on the presence or absence of volitional motor control at a specific joint, respectively. Many surgical procedures can be employed to optimize function, decrease pain, improve hygiene, and enhance cosmesis in patients with UMN syndrome.

RESUMO

STUDY DESIGN: Case series. INTRODUCTION: Upper extremity (UE) trauma and subsequent immobilization affects functional performance. PURPOSE OF THE STUDY: Determine the usefulness and feasibility of unilateral hand training (UHT) on improving functional performance in patients with UE trauma. METHODS: Nine participants received UHT within 10 days of immobilization. Functional performance, dexterity, grip, and pinch strength were measured at initial and 4-week visits. Qualitative interviews were coded to develop themes. RESULTS: All Jebsen-Taylor hand function test subtests improved from pretest to post-test. Disabilities of the Arm, Shoulder and Hand scores of all 9 participants improved. Functional performance was more impaired for participants with dominant UE injury. Four themes emerged: participants were forced to alter or avoid most daily activities, had an increased dependency on others, took longer to perform activities, and felt UHT decreased the impact of UE trauma on function. DISCUSSION: Functional performance was impaired for all participants. Participants believed that UHT was useful and contributed to improved function. CONCLUSION: This case series tracked a comprehensive intervention based on a holistic activities of daily living framework that considered the nuances of individual complexities of immobilization following hand trauma. Knowledge from this study supports an early intervention like UHT to educate clients on effective strategies to improve immediate activities of daily living functioning and potentially prevent longer term impairments.

RESUMO

PURPOSE OF REVIEW: Traumatic Brain Injury (TBI) remains the leading cause of morbidity and mortality in U.S. Since the last decade, there have been several advances in the understanding and management of TBI that have shown the potential to improve outcomes. The aim of this review is to provide a useful overview of these potential diagnostic and treatment strategies that have yet to be proven, along with an assessment of their impact on outcomes after a TBI. RECENT FINDINGS: Recent technical advances in the management of a TBI are grounded in a better understanding of the pathophysiology of primary and secondary insult to the brain after a TBI. Hence, clinical trials on humans should proceed in order to evaluate their efficacy and safety. SUMMARY: Mortality associated with TBI remains high. Nonetheless, new diagnostic and therapeutic techniques have the potential to enhance early detection and prevention of secondary brain insult.

RESUMO

BACKGROUND: The most recent management guidelines advocate computed tomography angiography (CTA) for any suspected vascular or aero-digestive injuries in all zones and give zone II injuries special consideration. We hypothesized that physical examination can safely guide CTA use in a "no zone" approach. METHODS: An 8-year retrospective analysis of all adult trauma patients with penetrating neck trauma (PNT) was performed. We included all patients in whom the platysma was violated. Patients were classified into three groups as follows: hard signs, soft signs, and asymptomatic. CTA use, positive CTA (contrast extravasation, dissection, or intimal flap) and operative details were reported. Primary outcomes were positive CTA and therapeutic neck exploration (TNE) (defined by repair of major vascular or aero-digestive injuries). RESULTS: A total of 337 patients with PNT met the inclusion criteria. Eighty-two patients had hard signs and all of them went to the operating room, of which 59 (72%) had TNE. One hundred fifty-six patients had soft signs, of which CTA was performed in 121 (78%), with positive findings in 12 (10%) patients. The remaining 35 (22%) underwent initial neck exploration, of which 14 (40%) were therapeutic yielding a high rate of negative exploration. Ninty-nine patients were asymptomatic, of which CTA was performed in 79 (80%), with positive findings in 3 (4%), however, none of these patients required TNE. On sub analysis based on symptoms, there was no difference in the rate of TNE between the neck zones in patients with hard signs (P = 0.23) or soft signs (P = 0.51). Regardless of the zone of injury, asymptomatic patients did not require a TNE. CONCLUSIONS: Physical examination regardless of the zone of injury should be the primary guide to CTA or TNE in patients with PNT. Following traditional zone-based guidelines can result in unnecessary negative explorations in patients with soft signs and may need rethinking.

RESUMO

BACKGROUND: The effectiveness of 14-French (14F) pigtail catheters (PCs) compared to 32-40F chest tubes (CTs) in patients with traumatic hemothorax (HTX) and hemopneumothorax (HPTX) is becoming more well known but still lacking. The aim of our study was to analyze our cumulative experience and outcomes with PCs in patients with traumatic HTX/HPTX. We hypothesized that PCs would be as effective as CTs. METHODS: Using our PC database, we analyzed all trauma patients who required chest drainage for HTX/HPTX from 2008 to 2014. Primary outcomes of interest, comparing PCs to CTs, included initial drainage output in milliliters (mL), tube insertion-related complications, and failure rate. For our statistical analysis, we used the unpaired Student's t test, Chi-square test, and Wilcoxon rank-sum test. We defined statistical significance as P < 0.05. RESULTS: During the 7-year period, 496 trauma patients required chest drainage for traumatic HTX/HPTX: 307 by CTs and 189 by PCs. PC patients were older (52 ± 21 vs. 42 ± 19, P < 0.001), demonstrated a significantly higher occurrence of blunt trauma (86 vs. 55%, P ≤ 0.001), and had tubes placed in a non-emergent fashion (Day 1 [interquartile range (IQR) 1-3 days] for PC placement vs. Day 0 [IQR 0-1 days] for CT placement, P < 0.001). All primary outcomes of interest were similar, except that the initial drainage output for PCs was higher (425 mL [IQR 200-800 mL] vs. 300 mL [IQR 150-500], P < 0.001). Findings for subgroup analysis among emergent and non-emergent PC placement were also similar to CT placement. CONCLUSION: PCs had similar outcomes to CTs in terms of failure rate and tube insertion-related complications, and the initial drainage output from PCs was not inferior to that of CTs. The usage of PCs was, however, selective. A future multi-center study is needed to provide additional support and information for PC usage in traumatic HTX/HPTX.
