Musculoskeletal injuries (MSIs) are a leading cause of separation from the U.S. Navy. Data have shown that several psychological responses to MSI are associated with treatment outcomes. Yellow flags are maladaptive psychological responses to injury and predict delayed recovery, whereas pink flags indicate resilience after MSI and are associated with good treatment outcomes. Identifying these factors in patients with MSI would permit early targeted care to address factors that may delay their readiness for deployment and enhance factors that support recovery. ⋯ A substantial portion of the sample endorsed elevated scores on one or more indicators of delayed recovery from MSI. Most participants showed a fear of physical activity, and approximately half reported pain-related distress (anxiety and depression). In addition, feelings of self-efficacy and positive outcome expectations of treatment were endorsed by only about half of the participants, indicating that the remaining half did not report adaptive responses to MSI. Early identification of these risk factors will allow for targeted treatment approaches that incorporate these yellow flags into treatment and support a psychologically informed approach to physical therapy. This approach is likely to reduce delayed recovery and improve deployment readiness.

The ongoing conflict in Ukraine from Russian invasion presents a critical challenge to medical planning in the context of multi-domain battle against a peer adversary deploying conventional weapon systems. The potential escalation of preventable morbidity and mortality, reaching a scale unprecedented since World War II, underscores the paramount importance of effective phases of care from Point of Injury (PoI)/Point of Wounding (PoW) or Point of Exposure (PoE) to Role 1 (R1) and Role 2 (R2) echelons of care.The NATO Vigorous Warrior (VW) Live Exercise (LIVEX) serves as a strategic platform for NATO and its partners, providing an opportunity to challenge operational concepts, experiment, innovate life-saving systems, and foster best practices across the Alliance. ⋯ The VW LIVEX provides a Concept Development and Experimentation platform for SIMEDIS refinement and conclusive insights into medical planning to reduce preventable morbidity and mortality. Recommending further iterations of similar methodologies at other NATO LIVEXs for validation is crucial, as is information sharing across the Alliance and partners to ensure best practice standards are met.

Cervical spondylosis in the warfighter is a common musculoskeletal problem and can be career-ending especially if it requires fusion. Head-mounted equipment and increased biomechanical forces on the cervical spine have resulted in accelerated cervical spine degeneration. Current surgical gold standard is anterior cervical discectomy and fusion (ACDF). Posterior cervical foraminotomy (PCF) is a nonfusion surgical alternative, and this can be effective in alleviating radiculopathy from foraminal stenosis caused by disc-osteophyte complex. Biomechanical studies have not been done to analyze motion associated with military aircrew personnel following PCF. The aim of this study was to compare the biomechanical responses of the effects of ACDF and PCF with different grades of facet resection under simulated military aircrew conditions using range of motion, disc pressure, and facet loads at the index and adjacent levels. ⋯ Posterior cervical foraminotomy is a motion-preserving implant-free surgical alternative to ACDF for warfighters with cervical radiculopathy after failure of conservative management. The treating surgeon must pay close attention to the extent of facet resection to avoid potential spinal instability and future disc and facet degeneration after PCF. Posterior cervical foraminotomy can be more advantageous than ACDF in terms of adjacent segment degeneration, motion preservation, reoperation rate, surgical cost, and retention of warfighters.

Sternal intraosseous (IO) access has advantages over humeral and tibial access for fluid resuscitation in military medical settings due to superior flow rates and pharmacokinetics. However, the morphology of the young adult manubrial cortical and medullary bone as it relates to IO catheter tips of currently available FDA-approved IO access devices is unclear. ⋯ Present findings suggest that both FAST1 and TALON sternal IO catheter tips can be successfully placed into the target medullary bone with high accuracy in male military members aged 18 to 30 who require rapid resuscitation.

Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a temporizing hemorrhage control intervention, but its inevitable effect on time to operating room (OR) has not been assessed. The aim of our study is to assess the impact of undergoing REBOA before surgery (RBS) on time to definitive hemorrhage control surgery. ⋯ Epidemiologic.
