Over the past 2 decades venous ultrasonography has become the standard primary imaging technique for the initial evaluation of patients for whom there is clinical suspicion of deep venous thrombosis (DVT) of the lower extremity veins. This article addresses the role of duplex ultrasonography and color Doppler ultrasonography in today's clinical practice for the evaluation of patients suspected of harboring a thrombus in their lower extremity veins. It reviews the clinical presentation and differential diagnoses, technique, and diagnostic criteria for acute and chronic DVT. In addition, it addresses the sonographic evaluation of venous insufficiency.

Gluteus medius contracture: A case report and review of the literature.
Medicine (Baltimore)
January 2025
Department of Orthopedics, China-Japan Union Hospital of Jilin University, Changchun, Jilin Province, PR China.
Rationale: Bilateral gluteus medius contractures in adults are rare in clinical practice, with only a few cases reported. These contractures may result from repeated intramuscular injections during childhood. Understanding the clinical manifestations, diagnostic process, treatment, and outcomes can provide insights into effective management strategies.

Introduction: The purpose of this study was to review rates of infection after civilian ballistic fractures and assess the effect of early antibiotic administration (EAA) on infection rates.
Methods: This was a retrospective cohort study done at an urban Level 1 Trauma Center. Patients ages 16 years and older with ballistic orthopaedic extremity injuries between May 2018 and December 2020 were enrolled.
Relationship between floating toe score and performance in track and field athletes.
PLoS One
January 2025
Graduate school of Health and Sports Science, Juntendo University, Chiba, Japan.
This study explored the relationship between floating toes and athletic performance among collegiate track and field athletes. A total of 422 athletes (sprinters, jumpers, and distance runners) and 136 controls participated in this study. Plantar surface images were captured using a specially designed foot scanner during standing to calculate the floating toe score.

PLoS One
January 2025
CFD Research Corporation, Huntsville, AL, United States of America.
Purpose: To assess physiological metrics during the use of a commercially available bilateral active ankle exoskeleton during a challenging military-relevant task and if use of the exoskeleton during this task influences: metabolic load, physiological measures or rate of perceived exertion.
Methods: Nine healthy volunteers (5M, 4F) completed this randomized cross-over design trial, with a baseline visit and two randomized test sessions (with/without the exoskeleton). Variables included impact on time to exhaustion during walking on a treadmill at varying speeds and gradients (0-15%) at 26.
Ultrasound Evaluation of Upper Limb Sublesional Muscle Morphology in Cervical Spinal Cord Injury.
Muscle Nerve
January 2025
International Collaboration on Repair Discoveries (ICORD), Vancouver, British Columbia, Canada.
Introduction/aims: Upper limb paralysis is arguably the most limiting consequence of cervical spinal cord injury (cSCI). There is limited knowledge regarding the early structural changes of muscles implicated in grasp/pinch function and upper extremity nerve transfer surgeries. We evaluated: (1) muscle size and echo intensity (EI) in subacute cSCI (2-6 months) and (2) the influence of lower motor neuron (LMN) damage on these ultrasound parameters.
