Evaluating the efficacy of hinged elbow braces in reducing passive valgus forces after ulnar collateral ligament injury-A biomechanical study.

Purpose: This biomechanical study aimed to investigate the effectiveness of a hinged elbow orthosis in reducing passive valgus forces following medial ulnar collateral ligament (UCL) injuries of the elbow joint. The hypothesis tested was that a hinged elbow orthosis reduces these passive valgus forces.

Methods: Eight fresh frozen cadaveric elbow specimens were prepared and tested under three scenarios: intact ligaments, simulated UCL rupture and application of a hinged elbow brace after simulated UCL rupture.

Machine learning-based assessment of regional-scale variation of landslide susceptibility in central Vietnam.

Recurrent landslide events triggered by typhoons and tropical storms over Vietnam pose a longstanding threat to the nation's population and infrastructure. Changes in hydroclimatic conditions, especially the growing intensity and frequency of storms, have elevated landslide susceptibility in many parts of the country. This research examines the spatio-temporal variations in landslide susceptibility across central Vietnam over several years, using multi-temporal landslide inventories from Typhoon Ketsana (2009), Tropical Storm Podul (2013), and Typhoon Molave (2020).

The temperature profile in elbow arthroscopy using radiofrequency ablation.

Introduction: Over the last decades, arthroscopic surgery has become increasingly relevant as its minimally invasive approach offers many benefits. To investigate the risks of orthoscopic surgery at the elbow, this study aimed to investigate the development of temperatures in elbow joints while performing radiofrequency ablation in arthroscopic surgery.

Materials And Methods: We performed standard arthroscopic surgeries with posterolateral, transtricipital and anterolateral approaches on seven cadaveric elbows and performed ablation on predefined locations with or without irrigation.

Improved restoration of biomechanical factors using a narrow-box shaped reconstruction compared to a wide one in superior capsular reconstruction for irreparable supraspinatus tendon tears: a biomechanical study using a static shoulder simulator.

Hypothesis And/or Background: Extensive, irreparable rotator cuff tears remain a surgical challenge and multiple treatment options are proposed and currently in use. To biomechanically compare superior glenohumeral translation, subacromial contact pressures, and area in a box-shaped reconstruction using the long head of the biceps tendon (LHBT) in an irreparable supraspinatus tendon tear model.

Methods: Seven cadaveric shoulders (mean age 61 years; range 32-84 years; standard deviation 22.

Evaluation of interleukin-6 in synovial fluid in periprosthetic joint infection of the elbow.

Purpose: Searching for quick determinable biomarkers with high sensitivity and specificity is necessary to improve and optimise the early diagnosis of periprosthetic elbow infection (PEI). Therefore, this study's objective was to evaluate the diagnostic value of synovial fluid interleukin-6 (IL-6) levels for diagnosing PEI in total elbow arthroplasty.

Method: Twelve prospective enrolled patients underwent total elbow arthroplasty revision surgery, during which synovial fluid was obtained.
