The instep flap for anterior ankle coverage with bone and hardware exposure.

Eur J Orthop Surg Traumatol 2021 Jun 12. Epub 2021 Jun 12.

Division of Orthopaedic and Trauma Surgery, Sahel General Hospital, University Medical Centre, PO Box 99/25., Ghoubeiry, Beirut, Lebanon.

Purpose: The instep medial plantar flap is a well-known flap based on the medial plantar artery of the foot and usually used for coverage of soft tissue defects of the heel area. It has seldom been reported for coverage of anterior ankle area with exposure of the bone and metallic hardware after open reduction and internal fixation of distal tibial fractures. The primary purpose of this study is to evaluate the feasibility and viability of this flap as well as its reliability saving the internal fixation devices and efficiency protecting bone healing; the secondary purpose is to assess the condition of the flap and its cosmetic appearance, as well as occurrence of complications related to its harvesting.

Severe Calcaneus Injury Probability Curves Due to Under-Body Blast.

Ann Biomed Eng 2021 Jun 11. Epub 2021 Jun 11.

Johns Hopkins University Applied Physics Laboratory, 11100 Johns Hopkins Road, Laurel, MD, 20723, USA.

The lower extremity is the most frequently injured body region to mounted soldiers during underbody blast (UBB) events. UBB events often produce large deformations of the floor and subsequent acceleration of the lower limb that are not sufficiently mitigated by the combat boot, leaving the calcaneus bone vulnerable to injury. Biomechanical experiments simulating UBB loading scenarios were conducted in a laboratory environment using isolated postmortem human subject (PMHS) leg components. Read More

The relationship between brachial-ankle pulse wave velocity and peripheral blood lymphocyte subsets in hypertensives: a cross-sectional study.

J Hum Hypertens 2021 Jun 11. Epub 2021 Jun 11.

Department of Geriatrics, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, China.

Arteriosclerosis is the common pathological basis of hypertension-related target organ damage, and pulse wave velocity (PWV) is commonly used to assess the degree of arterial stiffness. Previous studies have reported the correlation between peripheral blood inflammatory indicators and PWV in hypertensives, but few studies examined the role of immune cells in arteriosclerosis in the context of human hypertension. In order to enrich the understanding of this topic, we conducted a cross-sectional study on hospitalized hypertensives in Tongji Hospital of Tongji Medical College of Huazhong University of Science and Technology from January 2015 to February 2017 to investigate the relationship between brachial-ankle pulse wave velocity (baPWV) and peripheral blood lymphocyte subsets.

Functional Ankle Range of Motion but Not Peak Achilles Tendon Force Diminished With Heel-Rise and Jumping Tasks After Achilles Tendon Repair.

Am J Sports Med 2021 Jun 11:3635465211019436. Epub 2021 Jun 11.

Department of Physical Therapy, University of Delaware, Newark, Delaware, USA.

Background: Deficits in sporting performance after Achilles tendon repair may be due to changes in musculotendinous unit structure, including tendon elongation and muscle fascicle shortening.

Purpose/hypothesis: The purpose was to discern whether Achilles tendon rupture reduces triceps surae muscle force generation, alters functional ankle range of motion, or both during sports-related tasks. We hypothesized that individuals who have undergone Achilles tendon repair lack the functional ankle range of motion needed to complete sports-related tasks. Read More

The use of near-infrared spectroscopy in the diagnosis of peripheral artery disease: A systematic review.

Vascular 2021 Jun 10:17085381211025174. Epub 2021 Jun 10.

70309Kaunas University of Technology, Kaunas, Lithuania.

Background: Peripheral arterial disease is a stenosis or occlusion of peripheral arteries that results in compromised blood flow and muscle ischemia. The available diagnostic methods are mostly used to measure and visualize blood flow and are not useful in the evaluation of perfusion, especially in diabetic patients, which is now considered to be a research priority by most of the vascular societies around the world as this is still a relatively poorly studied phenomenon.

Objective: The aim of this review is to explore the clinical significance of muscle tissue oxygenation monitoring in lower-extremity peripheral artery disease diagnosis using the near-infrared spectroscopy method. Read More
