Gun shot injuries to the temporal bone: Anatomic predictors of mortality. Am J Otolaryngol 2024; 45:104134. [PMID: 38103487 DOI: 10.1016/j.amjoto.2023.104134] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2023] [Accepted: 11/27/2023] [Indexed: 12/19/2023]
Abstract
PURPOSE To explore anatomic predictors of mortality from gunshot wounds involving the temporal bone. METHODS A retrospective search of radiology reports was performed for all patients with CT reports suggestive of gunshot wounds (GSW) to the TB (2000-2020). All cases were reviewed by the senior author to confirm injury to the temporal bone. Detailed demographic and radiographic data were collected. MAIN FINDINGS A total of 120 patients met inclusion criteria. The majority of patients were male (n = 101) and the average age was 32.9. The squamosa was the most commonly involved subsite (n = 90), followed by the mastoid (n = 43). Squamosal entry site had the highest associated mortality (89.7 %). For those with known disposition, 65.8 % (79 of 120) expired on the same hospital admission. Inpatient otolaryngology consultation was noted in 18.3 % (n = 22) of patients, with poor outpatient follow-up. CONCLUSIONS This series represents the largest survey of GSW to the temporal bone to date. Although associated mortality is high and outpatient follow-up poor, otolaryngologists should be aware of associated morbidities to facilitate both inpatient and subsequent outpatient management.

Exploring lived experiences of gunshot wound survivors: A key to ethnographically informed public health interventions for curbing firearm violence. Injury 2024; 55:111240. [PMID: 38159335 DOI: 10.1016/j.injury.2023.111240] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/26/2023] [Revised: 11/16/2023] [Accepted: 11/24/2023] [Indexed: 01/03/2024]
Abstract
INTRO The high rates of gun violence in the United States are a recognized public health concern with increased attention since the 1990's. The predominant studies used in gun violence research have been epidemiological approaches and quantitative analyses. This study, instead, examines lived experiences of gunshot wound survivors to better understand their situations. This study also compared the different census categories and their types of gunshot wound injuries. Ethnographic informed analyses may inform public health interventions to decrease firearm injuries. METHODS Data was collected through a series of semi-structured interviews at the emergency department of an urban, Level-1, academic trauma center. 96 patients with gunshot wounds (GSWs) from 2018-2022 were included in the study. Thematic analysis was conducted after coding interview responses. RESULTS There was a significant difference found between the 2 census categories (White and Minority populations). Those who self-identified as white had more self-inflicted GSWs (6) than other groups. Those who self-identified in the minority population had more GSWs as a result of an altercation (36) or as an innocent bystander (20). Interview data also demonstrated a trend in changing opinions about firearms in a group of participants with remote previous gunshot wounds (pGSW). When compared to the acute gunshot wound group (aGSW) the previous gunshot wound group (pGSW) responses showed support for increased gun safety and policies that limit firearm access. CONCLUSION Different injury patterns between census groups demonstrates that multiple public health approaches will be needed to decrease firearm violence. Ethnographically informed approaches, including the support of people with previous GSW injuries, may help craft those interventions to reduce injury. Matched peer support programs represent one potential intervention to decrease secondary injury and firearm violence.

Increased Incidence and Mortality of Civilian Penetrating Traumatic Brain Injury in Sweden: A Single-Center Registry-Based Study. World Neurosurg 2024; 182:e493-e505. [PMID: 38040331 DOI: 10.1016/j.wneu.2023.11.129] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2023] [Accepted: 11/26/2023] [Indexed: 12/03/2023]
Abstract
BACKGROUND Penetrating trauma to the head and neck has increased during the past decade in Sweden. The aim of this study was to characterize these injuries and evaluate the outcomes for patients treated at a tertiary trauma center. METHODS Swedish trauma registry data were extracted on patients with head and neck injuries admitted to Karolinska University Hospital (Stockholm, Sweden) between 2011 and 2019. Outcome information was extracted from hospital records, with the primary endpoints focusing on the physiological outcome measures and the secondary endpoints on the surgical and radiological outcomes. RESULTS Of 1436 patients with penetrating trauma, 329 with penetrating head and neck injuries were identified. Of the 329 patients, 66 (20%) had suffered a gunshot wound (GSW), 240 (73%) a stab wound (SW), and 23 (7%) an injury from other trauma mechanisms (OTMs). The median age for the corresponding 3 groups of patients was 25, 33, and 21 years, respectively. Assault was the primary intent, with 54 patients experiencing GSWs (81.8%) and 158 SWs (65.8%). Patients with GSWs had more severe injuries, worse admission Glasgow coma scale, motor, scores, and a higher intubation rate at the injury site. Most GSW patients underwent major surgery (59.1%) as the initial procedure and were more likely to have intracranial hemorrhage (21.2%). The 30-day mortality was 45.5% (n = 30) for GSWs, 5.4% (n = 13) for SWs, and 0% (n = 0) for OTMs. There was an annual increase in the incidence and mortality for GSWs and SWs. CONCLUSIONS Between 2011 and 2019, an increasing annual trend was found in the incidence and mortality from penetrating head and neck trauma in Stockholm, Sweden. GSW patients experienced more severe injuries and intracranial hemorrhage and underwent more surgical interventions compared with patients with SWs and OTMs.

Do Females Have Worse Outcomes in Penetrating Trauma: A Single-Center Analysis. J Surg Res 2024; 293:632-638. [PMID: 37837819 DOI: 10.1016/j.jss.2023.09.045] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2023] [Revised: 08/15/2023] [Accepted: 09/03/2023] [Indexed: 10/16/2023]
Abstract
INTRODUCTION Penetrating trauma occurs less frequently in females than in males. Studies on penetrating injuries are conducted in predominantly male populations. We aim to elucidate the demographics and outcomes of penetrating trauma specifically in females to mitigate disparities of care in females. MATERIALS AND METHODS A retrospective review of hospitalized adult trauma patients suffering penetrating trauma from 2015 to 2021 was performed in an urban American College of Surgeon-verified level 1 trauma center. Patients were stratified by sex (females or males) and mechanism of injury (gun-related versus nongun-related). The primary outcome was mortality, and secondary outcomes included incidence of blood transfusion, incidence of surgical/interventional radiology (IR) interventions, hospital length of stay (LOS), and complications. Descriptive statistics were employed with a significance defined as P value <0.05. A multivariate logistic regression was used to determine the impact of sex on mortality, surgical/IR interventions, and hospital LOS. RESULTS Females with penetrating injury had lower Injury Severity Score (1 versus 4, P < 0.05) than males, but had similar mortality rates (4% versus 6%, P = 0.06). In multivariable logistic analysis adjusting for age and Injury Severity Score, while females experience 33% fewer OR/IR intervention, there was no statistically significant difference in mortality rates, hospital LOS, and complication rates between males and females. CONCLUSIONS Despite receiving fewer surgical/IR intervention, females with penetrating injuries have similar outcomes to their male counterparts. Further study is needed to study this discrepancy.

Infectious profiles in civilian gunshot associated long bone fractures. INTERNATIONAL ORTHOPAEDICS 2024; 48:31-36. [PMID: 37336798 DOI: 10.1007/s00264-023-05870-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/21/2023] [Accepted: 06/14/2023] [Indexed: 06/21/2023]
Abstract
PURPOSE There is a paucity of literature on infections in civilian gunshot associated with long bone fractures with the reported rates ranging from 0-15.7%.This study aimed to investigate the rates of infection associated with long bone fractures caused by civilian gunshots. The specific objectives were to determine if certain extremities were at a higher risk for infection and to identify the types of bacteria present in these infections by analyzing culture isolates. METHODS We conducted a retrospective review of consecutive patients aged 18-64 who sustained gunshot-associated long bone fractures at an urban Level I trauma centre from 2010 to 2017. Patient selection was based done through a institutional trauma centre database using international classification of diseases (ICD) 9 and 10 codes. We included patients who underwent surgical treatment, specifically fracture fixation, at our institution and excluded patients with fractures involving the pelvis, spine, foot, and hand. A total of 384 gunshot-associated long bone fractures in 347 patients were identified for analysis. Relevant patient-, injury-, and treatment-related variables were extracted from clinical records and radiographic reviews. Outcomes of interest included bony union, repeat operative procedures, and the development of deep infection. RESULTS 347 patients with 384 long bone fractures were included. 32 fractures in 32 patients developed an infection for an incidence of 9.3% of patients and 8.3% of fractures. Gram-positive bacteria were present in 23/32 (72.0%) culture isolates, gram-negative bacteria in 10/32 (31.3%) culture isolates, and six infections were polymicrobial. Staphylococcus 16/32 (50.0%) and Enterobacter 6/32 (18.8%) species were the most common isolates. Of the Staphylococcus species, 5/16 (31.3%) were MRSA. Lower extremity fractures had a greater risk for infection compared to the upper extremity (11.7% vs 3.7% p < 0.01) and fractures that developed an infection had a larger average zone of comminution (63.9 mm vs 48.5 mm p < 0.05). CONCLUSION This study investigated the rates of infection associated with long bone fractures caused by civilian gunshots. The overall infection rate observed in our series aligns with existing literature. Gram-positive bacteria were the predominant isolates, with a notable incidence of MRSA in our patient population, highlighting the need for considering empiric coverage. Additionally, gram-negative organisms were found in a significant proportion of infections, and a notable percentage of infections were polymicrobial. Our findings emphasize the importance of carefully assessing highly comminuted lower extremity fractures and implementing appropriate antibiotic coverage and operative debridement for patients with gunshot-related long bone fractures. While current prophylaxis algorithms for open fractures lack specific inclusion of gunshot wounds, we propose incorporating these injuries to reduce the incidence of infections associated with such fractures.

The wounding potential of assault rifles: analysis of the dimensions of entrance and exit wounds and comparison with conventional handguns. A multicentric study. Forensic Sci Med Pathol 2023:10.1007/s12024-023-00767-3. [PMID: 38146043 DOI: 10.1007/s12024-023-00767-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 12/15/2023] [Indexed: 12/27/2023]
Abstract
The appearance of a gunshot wound (GSW) is greatly influenced by the velocity of the projectile, where high-velocity projectiles (HVPs) are defined as ballistic agents reaching a muzzle velocity of > 600 m/s fired from assault rifles. The aim of the study is to present and explain the differences in the dimensions of entrance and exit wounds between the most used handguns and assault rifles and to propose a predictor of HVP, i.e., the ratio of exit and entrance wounds (EX/ENR). The surface area of entrance and exit GSWs and the EX/ENR were calculated. 66 perforating GSWs produced by NATO FMJ 7.62 × 52 mm and 5.56 × 42 mm fired from assault rifles were assigned to the HVP, while 64 lesions produced by conventional projectiles fired from revolvers and semi-automatic pistols were assigned to the low-velocity projectile (LVP) group. The dimensions of the exit wounds of the HVP group were significantly higher when compared to the LVP group (95% CI 0.9886-2.423, p < 0.05). The HVP group showed significantly higher values for the EX/ENR when compared to the LVP group (95% CI 2.617-7.173, p < 0.05). The evaluation of the EX/ENR can be considered an adequate tool to assess the type of weapon involved and to roughly estimate the associated wounding mechanisms, which can guide both the physician in the management and treatment of the patients affected by GSW, and the forensic pathologist in crime investigation.

Abstract
Gun violence killed over 46,000 Americans in 2021; almost 120,000 suffered gunshot wounds. This epidemic has attracted national attention and increasing concern from medical and surgical organizations, as evident in this special issue. 'Through and Through History' explores the surgical management of gunshot wounds from their earliest appearance in 14th-century Europe to the present. Interweaving the civilian and military experience, it details not only the evolution of care directly applied to patients but also the social, political, and scientific milieu that shaped decisions made and actions performed both in and out of the operating room. The article describes how surgeons have pushed the boundaries of medicine and science in each era, developing new therapies for their patients, a historical trend that persists today when such care has the potential to save tens of thousands of lives each year.

Abstract
BACKGROUND A paucity of literature exists specifically examining self-inflicted (SI) gunshot wounds (GSWs) to the hand and wrist, which impart greater energy and have a higher risk of adverse events than non-self-inflicted (NSI) GSWs. METHODS We retrospectively reviewed records of patients who presented to our plastic surgery service after sustaining acute GSWs involving the hand and wrist between 2016 and 2018. RESULTS We identified 60 patients who sustained GSWs involving the hand and wrist; 17 (28%) were SI, and 43 (72%) were NSI. Within the SI group, 100% of patients were Caucasian, with an average age of 54 years. Within the NSI cohort, 77% of patients were Black, 19% were Caucasian, and 4% identified as other. While not statistically significant, we noted a substantial increase in patients requiring operative intervention in the SI cohort (65% SI vs 37% NSI, P = .08). There was a statistically significant increase in patients requiring more than 1 operation in SI patients (24% SI vs 5% NSI, P = .04). Patients who sustained SI injuries were also more likely to present with acute carpal tunnel syndrome requiring urgent surgical release and to develop wound infections (12% vs 0%, P = .08). CONCLUSIONS Self-inflicted GSWs involving the hand and wrist are associated with greater morbidity than their low-energy NSI counterparts. Individuals presenting with SI GSWs are more likely to be older, to require multiple operations, to develop infections, and to present with acute carpal tunnel syndrome requiring urgent surgical decompression.

Abstract
OBJECTIVE Civilian gunshot wounds (GSWs) involving the skeletal spine and spinal cord in pediatric patients are fortunately rare. Nevertheless, their presentation mandates judicious evaluation, and their clinical outcomes remain poorly defined. Thus, the authors aimed to characterize the clinical course of this traumatic presentation in the pediatric population based on their institutional experience. METHODS A retrospective review of a level I trauma center database was performed for the period 2011-2021. Clinical data were included for patients aged ≤ 18 years who had presented with radiographic and clinical evidence of a GSW to the spine and had at least one documented follow-up at least 6 months after injury. The primary outcomes of the study were the categorization of gunshot injuries and the results of neurological and functional examinations. RESULTS A total of 13 patients satisfied the study selection criteria. The mean patient age was 15.7 ± 1.6 years, and all presentations were assault in nature. Most of the patients were male (n = 12, 92%) in gender, Black in race (n = 11, 85%), and from zip codes with a median household income below the local county average (n = 10, 77%). All patients presented with a minimum Glasgow Coma Scale score of 14. Examination at presentation revealed American Spinal Injury Association Impairment Scale (AIS) grade A in 3 cases (23%), grade B in 2 (15%), grade C in 1 (8%), grade D in 2 (15%), and grade E in 5 (38%). Gunshot injury involved all regions of the spine, most commonly the cervical and thoracic spine (n = 6 for each, 46%). In terms of skeletal injury, the most common injuries were to the facet (n = 10, 77%) and the pedicle (n = 8, 62%), with evidence of intracanal injury in 9 patients (69%). Neurosurgical intervention was pursued in 1 patient (8%). Overall, 7 patients (54%) experienced a complication during admission, and the median length of hospitalization was 12 days (range 1-88 days) without any mortality events. Within 90 days from discharge, 2 patients (15%) were readmitted to the hospital for further care. The mean follow-up was 28.9 months (range 6-74 months), by which only 1 patient (8%) had an improved AIS examination; all other patients remained at their initial AIS grade. CONCLUSIONS Pediatric GSWs involving the spine are typically nonfatal presentations, and their long-term functional outlook appears contingent on clinical examination findings at initial presentation. Although neurosurgical intervention is not necessary in most cases, judicious evaluation of radiographic and clinical examinations by a neurosurgical team is strongly recommended to optimize recovery.

Abstract
INTRODUCTION Firearm-related injuries impact the healthcare system, taxpayers, and injured patients due to lost productivity and reduced quality of life. The goal was to quantify the economic costs related to hospitalization for gunshot wounds (GSWs) at a single urban level 1 trauma center. MATERIALS AND METHODS 941 patients over 27 months were treated for GSW. Elements related to hospitalization including length of stay, surgical procedures, medications and therapies, and subsequent readmission were identified, and costs were determined, inclusive of fixed and variable direct and indirect costs of facility care. Costs were classified based on body region: abdominal, chest, soft tissue, extremity or pelvic girdle, and head/neck/face. RESULTS Mean age was 30 years, with 94% male. Most patients (81%) were admitted, and 8% sustained fatal injuries. Overall, 12% were seen previously or subsequently for additional, unrelated GSWs. Mean costs per patient were: $66,780 for abdominal GSWs; $3,986 for chest; $3,509 for soft tissue; $19,875 for extremities; $64,533 for head or neck, and means of $25,249 for two regions and $26,638 for three regions. Over the prospective period, 941 individuals sustained GSWs (approximately 35 per month). 37% were to the extremities, 23% were within the skin/subcutaneous tissue, 7% to the abdomen, 7% to the chest, 6% to the head or neck, and 20% to two or more body regions. Total facility costs for these 941 GSWs was $18.9 million, or $698,960 per month. 55% of the patients had Medicaid, and 33% were uninsured, resulting in substantial uncompensated expenses for the trauma center. CONCLUSION Firearm-related injuries generate considerable expense. Our data underestimated cost, as professional services and indirect costs associated with lost economic productivity of patients and caregivers were excluded. No objective assessment of the disastrous personal and social impact was projected. Moving forward, interventions to prevent initial injury and recidivism in this high-risk population are crucial.

Epidemiology of ballistic fractures in the United States: A 20-year analysis of the Firearm Injury Surveillance Study. Injury 2022; 53:3663-3672. [PMID: 36130861 DOI: 10.1016/j.injury.2022.09.011] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/29/2022] [Revised: 08/25/2022] [Accepted: 09/11/2022] [Indexed: 02/02/2023]
Abstract
INTRODUCTION Ballistic (i.e., gunshot-induced) fractures present unique treatment challenges and can be associated with high rates of complications and considerable morbidity. Large-scale epidemiologic data on these types of fractures are scarce. There is concern that gun-related violence may be on the rise, potentially increasing the burden of ballistic orthopaedic trauma, but there are few contemporary studies on the topic. The aim of this study, therefore, was to investigate the incidence and demographics of patients with ballistic fractures in the United States (US) over the last 20 years. MATERIALS AND METHODS This descriptive epidemiology study retrospectively analyzed the Firearm Injury Surveillance Study to identify cases of ballistic fractures in the US from 2000 to 2019. Overall and annual numbers of fractures and fracture incidence rates (IRs), patient demographics, incident characteristics, and temporal trends were analyzed. Patients of all ages were included. Ballistic fractures were grouped by anatomic location for comparisons (non-spine axial, spine, upper extremity, lower extremity). RESULTS An estimated N = 240,555 patients (n = 8,322 unweighted cases) sustained ballistic fractures over the 20-year study period for an overall IR of 39.2 per 1,000,000 person-years at-risk (PYR). Overall, lower extremity fractures accounted for the largest percentage of cases (45.9%; IR=18.8 PYR), followed by upper extremity fractures (32.8%; IR=13.4 PYR), non-spine axial fractures (16.1%; IR=6.6 PYR), and spine fractures (5.2%; IR=2.1 PYR). Diaphyseal femur fractures were the most common ballistic fractures overall. Nearly three-fourths (71.2%) of all cases occurred in males in the second through fourth decades. The most common injury intent was assault (71.8%) and a majority of patients (71.2%) required hospital admission. Accounting for population growth yielded a significantly increasing incidence of all ballistic fractures over the study period from 15.7 PYR in 2000 to 96.8 PYR in 2019 (average annual percent change=10.3, p < 0.00001). CONCLUSION These data suggest that the nationwide burden of ballistic fractures in the US has increased significantly in the last two decades. Ballistic fractures are associated with significant morbidity and societal cost, and increasing injury rates highlight the need for future research aimed at better understanding the ideal treatment of these types of fractures and their outcomes.

Abstract
BACKGROUND Gunshot wounds (GSWs) to the head in the pediatric population are both rare and devastating, with the clinical course of pediatric survivors poorly understood. Correspondingly, the aim of this study was to summarize the clinical complications clinicians can expect of survivors of GSW to the head in children and adolescents in hospital and after discharge. METHODS A retrospective review of our Level 1 trauma center database between 2011 and 2021 was performed. Clinical data was extracted for those patients aged ≤ 18 years old who survived initial hospitalization with at least one documented follow-up. Categorical data were then compared using Chi-squared test. RESULTS A total of 19 pediatric survivors of GSW to the head satisfied all selection criteria with an average age was 15.3 years. The majority of cases were isolated head injuries (63%), with an average Glasgow Coma Score (GCS) of 11.9. Bullet trajectory was intraparenchymal in 11 (58%) cases and extraparenchymal in 8 (42%) cases, with 15 (79%) patients treated by surgical intervention. A total of 13 (68%) patients experienced a complication during their hospitalization, with the most common being sympathetic hypertension and endocrinologic salt wasting, each occurring in 5 (26%) patients. With respect to complication categories, the intraparenchymal patients experienced statistically more complications than extraparenchymal patients that were infectious (54% vs 0%, P = 0.01) and sympathetic (45% vs 0%, P = 0.03) in nature. However, with respect to overall neurologic (P = 0.24), endocrinologic (P = 0.24), and traumatic (P = 0.24) complications, their incidences were statistically comparable. All patients were successfully discharged on average post-injury day 22 with an average GCS of 14.0. Mean follow-up for the cohort was 42.6 months, with an average GCS of 14.3. A total of 6 (32%) patients experienced a complication relatable to their initial GSW injury after discharge. The most common individual complication was new-onset seizures in 3 (16%) patients. CONCLUSIONS Survivors of pediatric GSW to the head can experience multi-systemic complications during both initial hospitalization and afterwards, and bullet trajectory involving the parenchyma may be associated with specific complications more than others. Dedicated inpatient management and outpatient follow-up involving surveillance for complications across all systems, not just neurological, are recommended to ensure patients receive the best care possible.

Abstract
STUDY DESIGN Retrospective. OBJECTIVE To evaluate functional outcomes and characteristics associated with gunshot wound (GSW) to the spine. METHODS Patients with GSW to the spine managed at a Level 1 Trauma Center from January 2003 to December 2017 were enrolled. Patient demographics, diagnoses, level of injury, American Spinal Injury Association (ASIA) score, ambulatory status at follow-up, bowel and bladder function, clinical improvement, and mortality were evaluated. Clinical improvement was defined as a progression in ambulatory status category at latest follow up. RESULTS 51 patients with GSW of the spine were identified. 48 (94.1%) were male and 3 (5.9%) were female, with a mean age of 27 years-old (range 15-56). 38 (74.5%) were Caucasian, 7 (13.7%) were African American, 1 (2.0%) Asian-American, and 5 (9.8%) were Other/Unknown. 46 (90.2%) patients had GSW related spinal fractures and 44 (86.3%) had neurological deficits. Among patients with neurologic deficits, 5 (9.8%) had Cauda Equina Syndrome, 1 (2%) had Brown-Sequard Syndrome, and 38 (74.5%) spinal cord injuries: ASIA A 26 (68.4%); ASIA B 3 (7.9%); ASIA C 7 (18.4%); ASIA D 2 (5.3%). At mean follow-up time of 4.2 years (SD 3.9), 27 (52.9%) patients were wheelchair bound, 11 (21.6%) were ambulating with assistance, and 13 (25.5%) had normal ambulation. ASIA grade (A or B) was significantly, P < 0.00001, associated with being wheelchair bound and having neurogenic bowel or bladder at follow-up. CONCLUSIONS Most spinal GSW patients (70.6%) did not have any clinical improvement in ambulatory status and most injuries were ASIA A.

Single dose IV Antibiotic for Low-Energy Extremity Gunshot Wounds: A Prospective Protocol. ANNALS OF SURGERY OPEN 2022; 3:e136. [PMID: 37600115 PMCID: PMC10431561 DOI: 10.1097/as9.0000000000000136] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2021] [Accepted: 01/20/2022] [Indexed: 11/26/2022] Open
Abstract
Objective To prospectively determine infection rate following low-energy extremity GSWs with a single dose IV antibiotic protocol. Summary Background Data Previous work suggests that a single IV antibiotic dose, without formal surgical debridement, mitigates infection risk. Methods Over 35 months 530 adults with low-energy GSWs to the extremities were included. Three hundred fifty-two patients (66%) had ≥30 days follow-up. Patients were administered a single dose of first-generation IV cephalosporin antibiotics, and those with operative fractures received 24-hour perioperative antibiotics. Injury characteristics, treatment, protocol adherence, and outcomes (infection) were assessed between the protocol group (single-dose antibiotics) and the non-protocol group (no antibiotics or extra doses of antibiotics). Results Compliance with the single-dose protocol occurred in 66.8%, while 33.2% received additional antibiotics or no antibiotics. The deep infection rate requiring surgical debridement was 0.8%, while the combined rate of all infections was 11.1%. Age, sex, injury location, multiple injuries, fracture presence, and type of surgery did not affect infection rate. Adherence to the antibiotic protocol was associated with a reduction in infection risk (odds ratio = 0.39, 95% confidence interval 0.19-0.83, P = 0.01). Receipt of additional antibiotics outside of our single-dose protocol did not predict further reduction in rate of infection (P = 0.64). Conclusions A standardized protocol of single-dose IV antibiotic appears effective in minimizing infection after low-energy GSW to the extremities. Level of Evidence Therapeutic Level II.

Abstract
BACKGROUND Gunshot wounds (GSWs) to the wrist and hand are a major health and economic burden in the United States. There are few studies examining the circumstances and epidemiological factors surrounding these injuries. This study assesses the epidemiological factors, as well as the shooting circumstances, injury details, and surgical management of wrist and hand GSWs in children and adults. METHODS Medical records and radiographs were reviewed for all patients with ballistic injury to the wrist or hand treated at an urban academic level 1 trauma center from 2016 to 2019. Fisher exact and Pearson χ2 tests were used to assess differences between groups. RESULTS Two hundred forty-nine victims (29 children, 220 adults) with complete documentation were identified. Among 180 victims with known shooting circumstances, 132 (70%) were shot by another person and 110 (65%) were injured by intentional gunfire. Eighty-seven victims (35%) suffered a concurrent GSW to another body region. Metacarpal fracture was the most commonly diagnosed bony injury (37%), followed by proximal phalanx fracture (25%). One hundred twenty-nine victims (52%) underwent surgery following their injuries. Nerve discontinuity was diagnosed in 27 victims (11%), while 20 victims (8%) had vascular disruption. There was no significant difference between children and adult victims' type of fracture, concurrent injuries, rates of surgery, or in the most common fracture fixation method. CONCLUSIONS Most wrist and hand GSW victims were injured due to intentional, non-self-inflicted gunfire. Most patients present with hand fractures, and fortunately, nerve and vascular disruptions are uncommon.

Timoteo Mendieta Alcalá and the Pact of Forgetting: trauma analysis of execution victims from a Spanish Civil War mass burial site at Guadalajara, Castilla la Mancha. Forensic Sci Int Synerg 2021; 3:100156. [PMID: 34179739 PMCID: PMC8212665 DOI: 10.1016/j.fsisyn.2021.100156] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2021] [Revised: 05/29/2021] [Accepted: 05/29/2021] [Indexed: 11/15/2022]
Abstract
Fascist dictator Francisco Franco was responsible for the torture, murder and covert burial of 150-200,000 civilians both during and after the Spanish Civil War (1936-1939). This comprises one of the largest concentrations of mass graves and victims in the world, yet efforts to exhume them have been strenuously blocked by subsequent governments. This research documents the 2017 exhumation of Timoteo Mendieta Alcalá and 27 other individuals executed between July and November 1939, and interred at the cemetery in Guadalajara, Castilla La Mancha. The analysis includes DNA identifications and an assessment of cultural (possessions) and bioarchaeological variables (age/sex, stature, palaeopathology) in order to contextualise studies of ante/peri-mortem trauma, and thus understand the decedents' lives and the manner in which they were treated before and up to the time of their executions. Of the 24 burials in the main grave, 23 (95.8%) showed gunshot trauma (GSW), 7 (29.2%) showed blunt force trauma (BFT) and 1 (4.2%) showed sharp force trauma (SFT). Five of the main group (20.8%) showed healing lesions indicative of often extensive assault in the weeks leading up to their execution; one individual had sustained 27 fractures. GSW patterns are consistent with an organised firing squad, followed by multiple GSW at close range in the back/side of the head. This research elucidates unrecorded aspects of fascist dominion in 1936-9, adds to extant research on pattern and method in global atrocities, and demonstrates the human cost of the Spanish Civil War to those who aim to trivialise it.

Incorporating conditional survival into prognostication for gunshot wounds to the head. J Neurosurg 2021; 135:1550-1559. [PMID: 33690152 PMCID: PMC8426440 DOI: 10.3171/2020.9.jns202723] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2020] [Accepted: 09/08/2020] [Indexed: 11/06/2022]
Abstract
OBJECTIVE Several scores estimate the prognosis for gunshot wounds to the head (GSWH) at the point of hospital admission. However, prognosis may change over the course of the hospital stay. This study measures the accuracy of the Baylor score among patients who have already survived the acute phase of hospitalization and generates conditional outcome curves for the duration of hospital stay for patients with GSWH. METHODS Patients in whom GSWH with dural penetration occurred between January 2009 and June 2019 were identified from a trauma registry at a level I trauma center in the southeastern US. The Baylor score was calculated using component variables. Conditional overall survival and good functional outcome (Glasgow Outcome Scale score of 4 or 5) curves were generated. The accuracy of the Baylor score in predicting mortality and functional outcome among acute-phase survivors (survival > 48 hours) was assessed using receiver operating characteristic curves and the area under the curve (AUC). RESULTS A total of 297 patients were included (mean age 38.0 [SD 15.7] years, 73.4% White, 85.2% male), and 129 patients survived the initial 48 hours of admission. These acute-phase survivors had a decreased mortality rate of 32.6% (n = 42) compared to 68.4% (n = 203) for all patients, and an increased rate of good functional outcome (48.1%; n = 62) compared to the rate for all patients (23.2%; n = 69). Among acute-phase survivors, the Baylor score accurately predicted mortality (AUC = 0.807) and functional outcome (AUC = 0.837). However, the Baylor score generally overestimated true mortality rates and underestimated good functional outcome. Additionally, hospital day 18 represented an inflection point of decreasing probability of good functional outcome. CONCLUSIONS During admission for GSWH, surviving beyond the acute phase of 48 hours doubles the rates of survival and good functional outcome. The Baylor score maintains reasonable accuracy in predicting these outcomes for acute-phase survivors, but generally overestimates mortality and underestimates good functional outcome. Future prognostic models should incorporate conditional survival to improve the accuracy of prognostication after the acute phase.

[PMID: 32418149 DOI: 10.1007/s10140-020-01781-6] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2020] [Accepted: 04/16/2020] [Indexed: 11/29/2022]
Abstract
Due to a combination of increasing indications for MR imaging, increased MRI accessibility, and extensive global armed conflict over the last few decades, an increasing number of patients now and in the future will present with retained metallic ballistic debris of unknown composition. To date, there are no guidelines on how to safely image these patients which may result in patients who would benefit from MRI not receiving it. In this article, we review the current literature pertaining to the MRI safety of retained ballistic materials and present the process we use to safely image these patients.

Abstract
INTRODUCTION The management of long bone lower limb fractures secondary to gunshot wounds (GSWs) in the civilian setting are complex and there is currently no consensus regarding the optimal approach to managing such fractures. This study aims to address the relationship of implant related sepsis in fractures secondary to GSWs. METHODS A systematic review of the literature was performed on both Pubmed and Scopus databases that look at fractures caused by GSWs in the lower limb. A total of 14 studies met the inclusion criteria set in this study. RESULTS Current literature suggests that low and high velocity injuries managed with internal fixation, such as intramedullary nails, may carry a low risk of superficial and deep infection, with no obvious risk of osteomyelitis. However, infection was poorly defined across all studies and no study used a validated scoring system for infection making it difficult to draw any valid conclusion on the rate of infection following internal fixation of lower limb fractures following both high and low velocity GSWs. CONCLUSION There is no clear evidence to confirm or refute that internal fixation is the ideal method of management in these complex injuries and guidance is needed due to the high and increasing proportion of patients presenting with these complex injuries worldwide.

Variation in treatment of low energy gunshot injuries - A survey of OTA members. Injury 2018; 49:570-574. [PMID: 29396308 DOI: 10.1016/j.injury.2018.01.027] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/27/2017] [Revised: 11/10/2017] [Accepted: 01/17/2018] [Indexed: 02/02/2023]
Abstract
The purpose of this study was to determine current practice patterns in the treatment of low energy gunshot wounds involving bones and joints. One hundred seventy-three Orthopaedic Trauma Association (OTA) members completed a web-based survey. The survey included practices for antibiotic therapy and operative treatment for different types of low-energy gunshot injuries. Six different scenarios of soft tissue injury, intra-articular injury, and fractures were described. Several permutations of antibiotic therapy and operative or non-operative management options were given as choices on the survey. Survey responses had a high degree of heterogeneity with only two treatment options receiving more than 50% agreement among responders: 54% agreed on joint exploration with perioperative antibiotics for gunshot wounds (GSWs) traversing a joint and 55% agreed on treating operative tibial shaft fractures from GSWs with fixation, along with debridement and irrigation of the GSW tract, and perioperative antibiotics. The majority of participants (69%) were either not aware of or not sure of an established protocol for treatment of GSW to bones and joints at their institution. Moreover, there is still wide variation in treatments among 31% of the participants who reported a protocol in place at their institutions. We conclude there is wide variation among orthopaedic surgeons in the antimicrobial prophylaxis and treatment of GSWs. Opportunity exists to develop standardized practices to minimize related infections, other complications, and costs.
