Chronic Leg Ischemia Caused by Arterial Bullet Embolization.

Intravascular shrapnel or bullet embolization after a gunshot injury is rare, with fewer than 200 cases reported over the past century. Military injuries typically have high energy transfer, making this phenomenon less prevalent. A 22-year-old military personnel presented with chronic leg ischemia resulting from arterial bullet embolization. Before 4 months, he had sustained a military injury and subsequently required hospitalization for pneumohemothorax. A 21-mm bullet obstructing the popliteal artery caused chronic leg ischemia and was scheduled for elective vascular surgery. Physicians should be aware of potential bullet embolization indications in gunshot wound patients to prevent complications, ensuring early detection and appropriate treatment for successful management.

Multiple organ failure following severe battle injuries during recent conflicts: a French retrospective cohort study.

Improvements in combat casualty care have increased survival rates, but these patients are at particular risk of developing multiple organ failure (MOF). We investigated the incidence and severity of MOF in a cohort of severe combat casualties. This retrospective study included all on-duty French land army war casualties with a severe combat injury requiring intensive care unit admission during 2009-2023. Demographic data, advanced life support interventions, and outcomes were collected. Each organ failure was then analyzed during a 7-day trauma course according to the Sequential Organ Failure Assessment (SOFA) score. Of the 100 patients who met the inclusion criteria, those with persistent MOF at day 4 (MOF group) represented 22% of the total population (median SOFA score 6.0 [5.3-8.0]). Compared to those without persistent MOF, these patients were more severely injured (median Military Injury Severity Score 38.0 [interquartile range 33.0-56.8] vs 26.5 [20.0-34.0], p < 0.001) by an explosive mechanism (68.2%) and sustained more traumatic brain injury (TBI; 40.9% vs 14.1%, p = 0.013). The MOF group also received significantly more blood units (median 14.0 [8.3-24.8] vs 6.0 [0.0-12.0], p < 0.001) and massive transfusions (68.2% vs 32.1%, p = 0.002). Pulmonary and cardiovascular dysfunction were the most frequently observed trauma outcomes. A multivariable logistic regression model showed that MOF persistence at day 4 was significantly associated (odds ratios [95% confidence intervals]) with severe injuries (1.5 [1-2.3], p = 0.042). A high number of severe lesions significantly and independently increased risk of MOF persistence at day 4 after combat-related trauma. These findings are particularly relevant to current and anticipated large-scale combat operations that will challenge battlefield casualty care and evacuation.

Surgical management of severe noncompressible torso and organ hemorrhages

Noncompressible torso hemorrhages (NCTH) are now recognized as the leading cause of preventable death in the context of severe military and civilian injuries. Approximately 20% of all trauma patients still die from uncontrolled bleeding associated with rapidly evolving disorders of blood coagulation function. Summary of recent advances in the field of nonsurgical and surgical management, presentation of current treatment concepts and future research directions. Selective literature review and analysis. The concepts for the early treatment of NCTH have considerably evolved over the last decade. The updated definition of NCTH includes acombination of high-grade anatomic body trunk injury, hemodynamic instability, urgent need for hemorrhage control, and aggressive hemostatic treatment. The treatment concepts consider the following 3 aspects: controlling the source of bleeding (close the tap), maintaining organ perfusion and restoring hemostasis (fill the tank) and increasing the body's resistance to ischemia (upgrade the armor). New tools, well-established damage control concepts and early and aggressive therapeutic intervention for hemostatic failure have significantly improved the outcomes. Future research needs to refine and validate the current concepts for further clinical application.

Methodology used to develop the minimum common data elements for surveillance and Reporting of Musculoskeletal Injuries in the MILitary (ROMMIL) statement

Background The objective was to summarize the methodology used to reach consensus for recommended minimum data elements that should be collected and reported when conducting injury surveillance research in military settings. This paper summarizes the methodology used to develop the international Minimum Data Elements for surveillance and Reporting of Musculoskeletal Injuries in the MILitary (ROMMIL) statement. Methods A Delphi methodology was employed to reach consensus for minimum reporting elements. Preliminary steps included conducting a literature review and surveying a convenience sample of military stakeholders to 1) identify barriers and facilitators of military musculoskeletal injury (MSKI) prevention programs, 2) identify relevant knowledge/information gaps and 3) establish future research priorities. The team then led a sequential three-round Delphi consensus survey, including relevant stakeholders from militaries around the world, and then conducted asynchronous mixed knowledge user meeting to explore level of agreement among subject matter experts. Knowledge users, including former and current military service members, civil servant practitioners, and global-wide subject matter experts having experience with policy, execution, or clinical investigation of MSKI mitigation programs, MSKI diagnoses, and MSKI risk factors in military settings. For each round, participants scored each question on a Likert scale of 1-5. Scores ranged from No Importance (1) to Strong Importance (5). Results Literature review and surveys helped informed the scope of potential variables to vote on. Three rounds were necessary to reach minimum consensus. Ninety-five, 65 and 42 respondents participated in the first, second and third rounds of the Delphi consensus, respectively. Ultimately, consensus recommendations emerged consisting of one data principle and 33 minimum data elements. Conclusions Achieving consensus across relevant stakeholders representing military organizations globally can be challenging. This paper details the methodology employed to reach consensus for a core minimum data elements checklist for conducting MSKI research in military settings and improve data harmonization and scalability efforts. These methods can be used as a resource to assist in future consensus endeavors of similar nature.

Prevalence and risk factors of training-related abdominal injuries: A multicenter survey study

PurposeThis study aims to identify the prevalence and risk factors of military training-related abdominal injuries and help plan and conduct training properly. MethodsThis questionnaire survey study was conducted from October 2021 to May 2022 among military personnel from 6 military units and 8 military medical centers and participants’ medical records were consulted to identify the training-related abdominal injuries. All the military personnel who ever participated in military training were included. Those who refused to participate in this study or provided an incomplete questionnaire were excluded. The questionnaire collected demographic information, type of abdominal injury, frequency, training subjects, triggers, treatment, and training disturbance. Chi-square test and t-test were used to compare baseline information. Univariate and multivariate regression analyses were used to explore the risk factors associated with military training-related abdominal injuries. ResultsA total of 3058 participants were involved in this study, among which 1797 (58.8%) had suffered training-related abdominal injuries (the mean age was 24.3 years and the service time was 5.6 years), while 1261 (41.2%) had no training-related abdominal injuries (the mean age was 23.1 years and the service time was 4.3 years). There were 546 injured patients (30.4%) suspended the training and 84 (4.6%) needed to be referred to higher-level hospitals. The most common triggers included inadequate warm-up, fatigue, and intense training. The training subjects with the most abdominal injuries were long-distance running (589, 32.8%). Civil servants had the highest rate of abdominal trauma (17.1%). Age ≥ 25 years, military service ≥ 3 years, poor sleep status, and previous abdominal history were independent risk factors for training-related abdominal injury. ConclusionMore than half of the military personnel have suffered military training-related abdominal injuries. Inadequate warm-up, fatigue, and high training intensity are the most common inducing factors. Scientific and proper training should be conducted according to the factors causing abdominal injuries.

Upper Extremity Ballistic Nerve Injury

» Gunshot injuries to the upper extremity (UE) have high likelihood for causing peripheral nerve injury secondary to the high density of vital structures. Roughly one-fourth of patients sustaining a gunshot wound (GSW) to the UE incur a nerve injury. Of these nerve injuries, just over half are neurapraxic. In cases of surgical exploration of UE nerve injuries, nearly one-third demonstrate a transected or discontinuous nerve.» Existing literature regarding surgical management of nerve injuries secondary to GSWs comes from both military and civilian injuries. Outcomes are inconsistently reported, and indications are heterogeneous; however, reasonable results can be obtained with nerve reconstruction.» Our proposed management algorithm hinges on 4 treatment questions: if there is a nerve deficit present on examination, if there is a concomitant injury in the extremity (i.e., fracture or vascular insult), whether the injured nerve would be in the operative field of the concomitant injury, and whether there was an identified nerve lesion encountered at the time of surgery by another surgeon?» Early exploration rather than continued expectant management may offer improved recovery from GSW nerve injuries in particular situations. When an UE nerve deficit is present, establishing follow-up after the initial GSW encounter and early referral to a peripheral nerve surgeon are pivotal.

There is a knowledge mobilization gap in musculoskeletal injury research in the military context

Musculoskeletal injuries (MSKIs) place a significant burden on military populations. While a considerable amount of research is being conducted to reduce the prevalence and impact of such injuries, rates of medical release due to MSKIs remain high. Military injury surveillance framework and research programs could be more successful if communication was improved by 1) engaging leadership at each step, 2) translating and disseminating findings to directly support personnel (e.g., health care professionals, physical training staff), and 3) presenting and discussing findings with service members to educate them and to interpret results. This article highlights a gap in knowledge sharing between the research community, military members, and practitioners supporting humans in uniform.

Current State, Needs, and Opportunities for Wearable Robots in Military Medical Rehabilitation and Force Protection.

Despite advances in wearable robots across various fields, there is no consensus definition or design framework for the application of this technology in rehabilitation or musculoskeletal (MSK) injury prevention. This paper aims to define wearable robots and explore their applications and challenges for military rehabilitation and force protection for MSK injury prevention. We conducted a modified Delphi method, including a steering group and 14 panelists with 10+ years of expertise in wearable robots. Panelists presented current wearable robots currently in use or in development for rehabilitation or assistance use in the military workforce and healthcare. The steering group and panelists met to obtain a consensus on the wearable robot definition applicable for rehabilitation or primary injury prevention. Panelists unanimously agreed that wearable robots can be grouped into three main applications, as follows: (1) primary and secondary MSK injury prevention, (2) enhancement of military activities and tasks, and (3) rehabilitation and reintegration. Each application was presented within the context of its target population and state-of-the-art technology currently in use or under development. Capturing expert opinions, this study defines wearable robots for military rehabilitation and MSK injury prevention, identifies health outcomes and assessment tools, and outlines design requirements for future advancements.

Effectiveness analysis of double EndoButton suture fixation Latarjet procedure for treatment of anterior shoulder dislocation with glenoid bone defect caused by military training injuries

To investigate the effectiveness of double EndoButton suture fixation Latarjet procedure in the treatment of shoulder anterior dislocation with glenoid bone defect caused by military training injuries. The clinical data of 14 patients with anterior shoulder dislocation with glenoid bone defect due to military training injuries who met the selection criteria and admitted between August 2021 and December 2022 were retrospectively analyzed. All patients were male, the age ranged from 21 to 38 years, with an average of 26.8 years. The time from initial dislocation to operation was 6-15 months, with an average of 10.2 months. Anterior shoulder dislocation occurred 5-12 times, with an average of 8.2 times. All glenoid bone defects were more than 10%, including 5 cases of 10%-15%, 8 cases of 15%-20%, and 1 case of 24%. All patients were treated by double EndoButton suture fixation Latarjet procedure. The operation time and complications were recorded. The shoulder function and pain were evaluated by the American Association for Shoulder and Elbow Surgery (ASES) score, Rowe score, Instability Severity Index Score (ISIS), and visual analogue scale (VAS) score before and after operation. The range of motion of the shoulder was recorded, including forward flexion, 0° external rotation, and abduction 90° external rotation. The position, healing, and resorption of the bone mass were evaluated by three-dimensional CT of shoulder joint after operation. All patients successfully completed the operation, and the operation time was 100-150 minutes, with an average of 119.7 minutes. There was no complications such as infection, vascular and nerve injury. All patients were followed up 12-20 months, with an average of 15.6 months. During the follow-up, 4 patients had bone mass separation, absorption, and recurrent anterior dislocation, and the shoulder joint fear test was positive. Imaging of the remaining patients showed that the bone mass healed well, no anterior dislocation recurrence occurred, and the healing time was 3-7 months (mean, 4.7 months). At last follow-up, the range of motion, ASES score, Rowe score, ISIS score, and VAS score of the patients significantly improved when compared with those before operation ( P<0.05). The effectiveness of double EndoButton suture fixation Latarjet procedure for the treatment of anterior shoulder dislocation with glenoid bone defect caused by military training injury is satisfactory.

Understanding Women's Transitions from Military to Department of Veterans Affairs Care.

Background: Over the past two decades, increasing numbers of women have served in the military, with women now comprising 17.3% of active-duty personnel and 21.4% of National Guard and reserves. During military service, women often incur painful musculoskeletal (MSK) injuries related to carrying heavy loads and wearing ill-fitting gear. While women may receive initial care for these injuries under the auspices of the Department of Defense (DoD), these injuries often linger and further treatment in required as women transition to Department of Veterans Affairs (VA) care. However, little is known about this transition process, and whether women are given adequate information and support regarding how to access VA care after their military service has ended. Research Design: To better understand these issues, we interviewed 65 women veterans with military service-related MSK injuries about their transition from DoD to VA care. Results: Six major themes emerged from the interviews. Those themes were: (1) Military injuries are often related to ill-fitting gear or carrying heavy loads; (2) Stigma/discrimination related to military injuries; (3) Limited assistance with transition between DoD and VA to manage ongoing injuries and pain; (4) Women have a difficult time managing perceptions and expectations of their weight after military service; (5) Childcare is a substantial burden for veterans in self-care; and (6) veterans desire peer-support services to help them stay healthy. Conclusions: Based on these findings, DoD and VA should continue to work together to develop programs to educate and support women as they transition from military to VA care. Furthermore, VA should consider developing peer support programs for women Veterans who may require additional support to maintain health, especially among Veteran mothers who have complex family responsibilities that may limit their ability to focus on their own health.

Current Status of Cold Injuries in the South Korean Military Over the Past 5 Years: Analysis and Assessment Based on the 2023-2024 Surveillance System.

This study aimed to examine the prevalence of cold injuries and review the cold injury monitoring system in the South Korean military. This study conducted a retrospective and cross-sectional analysis using data from the Defense Medical Statistic Information System (DMSIS) on cold injuries among military personnel from 2018 to 2023. It incorporated findings from the Korean Armed Forces Medical Command's cold injury surveillance system and analyzed cases from the Armed Forces Capital Hospital, covering all branches of the military by status and rank. An analysis of cold injury in the South Korean military over the past 5 years revealed varying numbers of cases treated, from 799 in 2018-2019 to 467 in 2022-2023. According to the surveillance system in 2023-2024, the Army experienced the majority of these cases, with 94.5% of the total. The incidence per 1,000 personnel was the highest in the Army at 0.98 compared to the Air Force and Navy/Marine Corps. Rank-based analysis indicated the most affected were private first-class soldiers. Frostbite was the most frequent condition, alongside chilblains, hypothermia, and immersion injuries, with no marked difference in the type of illness across branches. The study underscores the need for focused prevention and treatment, particularly in the Army. By analyzing data from a newly implemented surveillance system, it revealed a higher incidence of frostbite and chilblains among lower ranks. The findings highlight the importance of targeted educational measures and enhanced response strategies to protect personnel against cold injuries.

Viability of Structured Gait Retraining for Improving Clinical Outcomes Following Running-related Injury in Active Duty Service Members.

All branches of the U.S. Military have a running component of their physical readiness testing battery. Running-related musculoskeletal injuries affect 20 to 40% of DoD Service Members each year. Running form has not historically been addressed with military running-related injuries. To assess the utility of a structured gait retaining protocol designed to treat the onset of running-related pain and/or injury by correcting identified biomechanical risk factors for injury and improve clinical outcomes. Case series. A total of 160 Active Duty Service Members (ADSMs) with running-related lower-body musculoskeletal injuries were referred by a physical therapist for a multisession gait retraining program termed "Run with CLASS" (Cadence, Lean, Alignment, Soft-landing, Strike). Run with CLASS utilized various drills to emphasize impact progression, proximal strengthening, and proprioception and spatial awareness. Results revealed that the implemented gait retraining protocol significantly improved running parameters following lower-body injury as evidenced by increased cadence, improved functional assessment scores, and a marked transition from predominantly heel strike to forefoot strike patterns during running. A 3-week supervised gait retraining program focused on the gait retraining program termed "Run with CLASS" (Cadence, Lean, Alignment, Soft-landing, Strike) was successful in altering biomechanics of self-selected running gait by increasing cadence and transitioning ADSMs to a forefoot foot strike. Additionally, ADSMs reported significant improvements on the self-reported functional scores on the University of Wisconsin Running Injury and Recovery Index and Single Assessment Numerical Evaluation. 4.

Adjusting to a Partners’ Changed Appearance Following Military Combat-Related Appearance-Altering Injuries: The Challenges of Looking “Different” and How Life Continues

Combat-related physical injuries not only affect the individual but also close family members. Emerging evidence indicates that injuries that change appearance, such as limb loss and physical scarring, may create additional psychosocial challenges for the injured person and their family. However, to date the impact of appearance-altering combat injuries have not been explored among the partners of those who were injured. Using a qualitative individual interview design, this study aimed to gain experiential insights into the appearance-specific impact on the partners of military personnel who sustained appearance-altering injuries during deployments or training. Reflexive Thematic Analysis of interviews with 11 female partners identified two main themes “The challenges of looking different” and “How our life continues.” The themes reflect challenges experienced by the partners in relation to their injured partner looking “different” from societally accepted appearance ideals, and the impact this could have on their children. Yet, they had found ways for life to continue such as drawing on positive emotions, having gratitude, pride in their partner’s service, and normalizing difference for their children. While the partners found ways to adapt, this study draws attention to unmet needs for appearance-specific support.

Military Injuries: Helocasting Accident.

Accidental injuries sustained during helocasting remain unexamined. Conditions prevalent during a helocasting exercise performed at a still water body and the resulting casualties were analyzed. Despatch from greater-than-ideal height (>7 m) and speed (>5 knots) causes a high-velocity impact of the body with water in a non-aerodynamic configuration, exposing maximal body area at penetration. The brunt is borne by the torso/back, specifically, the lungs, ribs, and posterior aspect of the spine. The injuries result from direct trauma, sudden deceleration, barotrauma, and hyperflexion. Computerized tomography (CT) is the imaging of choice in the assessment of these injuries. Prompt evacuation to an equipped center, whilst stabilizing the spine in the suspected, proves pivotal to the outcome. Adverse slamming dynamics cause accidental injuries in helocasting. Thorax and spine are predominantly traumatized, both directly and indirectly, and are assessed best using CT. Timely spine stabilization and evacuation prove vital. Accurate assessment of height/speed and adherence to their ideal limits, at despatch, may avert such injuries.

The use of immunological drugs for the treatment of wound infections in military personnel during hostilities

Aims: To assesses the trends in immunological drug development for managing wound infections in military personnel. To discuss the efficacy, safety, and long-term results, focusing on combination therapies, and identifying research deficits for improving the care of military wounds. Methodology: A narrative review was used in order to explores the use of immunological drugs for treating wound infections in military settings utilising a search strategy identified 840 publications from PubMed, with 6 studies meeting inclusion criteria for analysis from the years 2019 to 2022. Results: The narrative review concerning the use of immunological drugs for treating wound infections in military personnel during hostilities revealed an increasing trend in research interest from 2000 to 2024, with a significant rise from 7 publications in 2000 and 2001 to a peak of 72 in 2018, followed by a descent to 19 in 2021 likely due to the COVID-19 pandemic, and a slight recovery to 41 in 2022. The key findings included a 50% reduction in infection rates and a 30% faster healing time with monoclonal antibody treatments, over 95% accuracy in species identification of MDR strains, and reduced bacteremia incidence with GM-CSF and G-CSF. Adverse effects varied from mild to moderate, including infusion reactions, nausea, and fatigue. The highlighted challenges included the need for larger sample sizes, long-term follow-up, optimal dosages, and studying diverse populations. Scientific Novelty: Explore the innovative realm of immunological drugs, a promising frontier in combating wound infections among military personnel during active hostilities. Conclusion: The review also identified new developments in immunomodulatory agents for military wound infection, which are effective in decreasing infection rates and enhancing the rate of wound healing.

Military health system auditory blast injury prevention standard

The Department of Defense (DoD) lacks a single medical standard for prevention of auditory blast injury, relying on the Service Branches to develop their own guidance. The DoD Executive Agent established the Blast Injury Prevention Standards Recommendation (BIPSR) process, led by the DoD Blast Injury Research Coordinating Office (BIRCO), to investigate the effects of blast injuries on warfighters. The BIPSR Process implementation of the Auditory Blast Injury Type illuminated characteristics, capabilities, and limitations of current capabilities to predict and prevent auditory injuries. The evaluation resulted in the recommendation of 8-h Equivalent Level (LAeq8hr) as the interim MHS Auditory Blast Injury Prevention Standard to serve as the cross-Service standard while the community performs additional research to fill critical knowledge gaps. BIRCO is working to formalize the Military Health System Auditory Blast Injury Prevention standard to support updates and coordination across DoD guidance including military design standards and health protection policies.

Military and Nonmilitary TBI Associations with Hearing Loss and Self-Reported Hearing Difficulty among Active-Duty Service Members and Veterans.

Identify associations between self-reported history of military and nonmilitary traumatic brain injury (TBI) on hearing loss and hearing difficulty from the Noise Outcomes in Servicemembers Epidemiology (NOISE) study. Cross-sectional. Multi-institutional tertiary referral centers. Four hundred seventy-three Active-Duty Service members (ADSM) and 502 veterans. Self-reported history of no TBI, military TBI only, nonmilitary TBI only, both military and nonmilitary TBI. Pure-tone hearing thresholds, Speech Recognition In Noise Test (SPRINT), Hearing Handicap Inventory for Adults (HHIA), and Speech, Spatial and Qualities of Hearing Scale (SSQ)-12. 25% (120/473) of ADSM and 41% (204/502) of veterans self-reported a TBI. Military TBI was associated with poorer hearing thresholds in all frequency ranges in veterans (adjusted mean difference, 1.8 dB; 95% confidence interval [CI], 0.5-3.0; 3.3, 0.8-5.8; 5.1; 1.7-8.5, respectively), and in the high frequency range in ADSM (mean difference, 3.2 dB; 95% CI, 0.1-6.3). Veterans with military TBI only and nonmilitary TBI only had lower odds of correctly identifying speech in noise than veterans with no TBI (odds ratio [OR], 0.78; 95% CI, 0.72-0.83; 0.90; 0.84-0.98). ADSM with a military TBI (OR, 5.7; 95% CI, 2.6-12.5) and veterans with any TBI history (OR, 2.5; 95% CI, 1.5-4.3; OR, 2.2; 95% CI, 1.3-3.8; OR, 4.5; 95% CI, 2.1-9.8) were more likely to report hearing difficulty on HHIA. SSQ-12 results corroborated HHIA findings. Military TBI was associated with poorer hearing thresholds in veterans and ADSM, and poorer SPRINT scores in veterans. Military TBI was associated with poorer self-perceived hearing ability in ADSM. All types of TBI were associated with poorer self-perceived hearing ability in veterans, although the strength of this association was greatest for military TBI.

Moral Injury Post-COVID-19: More Than Military? A Theological Perspective.

The author of this article considers moral distress theologically, as a potential shattering of core sustaining belief systems, hope, securities, self-identities, and organizing principles of one's existence. Shattering of individual moral expectations can occur in both medical and military moral injury.
