An ultrasound and shear wave elastography study: effect of grip on medial elbow joint morphology during valgus stress.

ABSTRACT:

Background

The flexor pronator mass (FPM) is an important dynamic stabilizer to valgus stress at the elbow and has been reported to protect against ulnar collateral ligament (UCL) injury. Active gripping and pronation have demonstrated reduced ulnohumeral joint space and change in material properties of the UCL when examined in vivo via ultrasound. No studies have utilized ultrasonography and shear wave elastography to characterize the medial elbow's response to FPM activation under valgus stress. This cross-sectional, repeated measures study aims to characterize medial elbow changes in UCL and FPM tissue stiffness and joint space width (JSW) during valgus stress with incremental FPM activation through gripping.

Methods
