Introduction: Lower extremity injury is common in the military and can lead to instability, pain, and decreased function. Military service also places high physical demands on service members (SMs). Standard treatment interventions often fail to align with these unique demands.

Background: Persons with lower limb amputation often experience decreased physical capacity, difficulty walking, and increased fall risk. To either prevent or recover from a loss of balance, one must effectively regulate their stepping movements. It is therefore critical to identify how well persons with amputation regulate stepping.

Volumetric muscle loss (VML) injuries are characterized by a heightened immune response that alters canonical wound healing outcomes and results in a chronic reduction of both total myofiber number and functional capacity. Preclinical and clinical investigations aimed at repairing VML injuries have largely utilized biologic scaffolds (BSs) as a potential therapeutic intervention. BSs rely on the recruitment of a myriad of host-derived immune, stem, and stromal cells to induce a wound healing response that has been routinely characterized as largely fibrous matrix deposition and limited myofiber regeneration at the site of the defect.

 Blood flow restriction (BFR) therapy is an emerging addition to rehabilitative programs that allows patients to increase strength at lower loads over shorter time periods. Therefore, we conducted a study to evaluate the safety and efficacy of a rehabilitation program using BFR to a traditional rehabilitation protocol following operative fixation of distal radius fractures.  A randomized controlled study was conducted comparing a standardized rehabilitation protocol alone to a combined protocol with the use of BFR therapy in patients treated with volar plate fixation following a displaced distal radius fracture.

Pleiotropic actions of Vitamin D in composite musculoskeletal trauma.

Injury

October 2020

DoD-VA Extremity Trauma and Amputation Center of Excellence, Bethesda, MD, USA; Department of Surgery, Uniformed Services University of the Health Sciences and Walter Reed National Military Medical Center, Bethesda, MD, USA. Electronic address:

Composite tissue injuries are the result of high energy impacts caused by motor vehicle accidents, gunshot wounds or blasts. These are highly traumatic injuries characterized by wide-spread, penetrating wounds affecting the entire musculoskeletal system, and are generally defined by frank volumetric muscle loss with concomitant segmental bone defects. At the tissue level, the breadth of damage to multiple tissue systems, and potential for infection from penetration, have been shown to lead to an exaggerated, often chronic inflammatory response with subsequent dysregulation of normal musculoskeletal healing mechanisms.

Muscle Contributions to Balance Control During Amputee and Nonamputee Stair Ascent.

J Biomech Eng

December 2020

Walker Department of Mechanical Engineering, The University of Texas at Austin, 204 E. Dean Keeton Street, Stop C2200, Austin, TX 78712.

Dynamic balance is controlled by lower-limb muscles and is more difficult to maintain during stair ascent compared to level walking. As a result, individuals with lower-limb amputations often have difficulty ascending stairs and are more susceptible to falls. The purpose of this study was to identify the biomechanical mechanisms used by individuals with and without amputation to control dynamic balance during stair ascent.

Objective: Pain is a significant public health issue that may be particularly problematic among injured service members who are at high risk of chronic physical and mental health conditions. The goals of this study were to describe the prevalence and types of low back pain (acute vs. recurrent) among service members injured while on combat deployments, and to examine the differences in posttraumatic stress disorder (PTSD) and depression prevalence and severity, as well as quality of life, for individuals with low back pain compared with those without.

Evolution of Fatigue Damage in the L5-S1 Intervertebral Disc Resulting from Walking Exposures Among Persons with Lower Limb Loss.

Ann Biomed Eng

F. Joseph Halcomb III, M.D. Department of Biomedical Engineering, University of Kentucky, 514E Robotic and Manufacturing Building, Lexington, KY, 40506, USA.

Article Synopsis
  • A study assessed fatigue damage in the L5-S1 spinal disc among 52 individuals with unilateral limb loss and 26 uninjured controls using a fatigue model related to spine motion.
  • Results showed that, assuming similar walking activity, those with and without limb loss experienced similar times to spinal damage, with faster walking and higher daily step counts leading to quicker fatigue.
  • The findings suggest that psychosocial factors may play a significant role in developing low back pain in limb loss patients, indicating that further research could improve clinical interventions for managing physical risks related to their condition.

Introduction: Powered prostheses are a promising new technology that may help people with lower-limb loss improve their ability to perform locomotion tasks. Developing active prostheses requires robust design methodologies and intelligent controllers to appropriately provide assistance to the user for varied tasks in different environments. The purpose of this study was to validate an impedance control strategy for a powered knee and ankle prosthesis using an embedded sensor suite of encoders and a six-axis load cell that would aid an individual in performing common locomotion tasks, such as level walking and ascending/descending slopes.

Purpose: The small bites surgical technique supported by the STITCH trial has been touted as a strategy for preventing early laparotomy dehiscence through greater force distribution at the suture-tissue interface. However, this hernia prevention strategy requires an alteration in the standard closure technique that has not been widely adopted in the USA. This study seeks to determine whether incorporating a mid-weight polypropylene mesh material into a hollow-bore surgical suture material will effectively increase the force distribution at the suture-tissue interface and potentially help prevent early laparotomy dehiscence in an ex vivo model.

Selecting an optimal prosthetic foot is particularly challenging for highly active individuals with limb loss, such as military personnel, who need to seamlessly perform a variety of demanding activities/tasks (often with and without external loads) while minimizing risk of musculoskeletal injuries over the longer term. Here, we expand on prior work by comparing biomechanical and functional outcomes in two prosthetic feet with the largest differences in mechanical response to added load (i.e.
