Overview

Información sobre este estudio

There have been a wide variety of techniques suggested for performing stress sonography of the elbow medial ulnar collateral ligament (mUCL) to evaluate for underlying ulnohumeral joint (UHJ) instability. This is clinically relevant when using ultrasound to diagnose mUCL injuries by measuring ulnohumeral joint widening under stress. To assist the ultrasound operator, prior measurement techniques have stabilized, and stress loaded the elbow with a second operator or specialized instrumentation (Telos Device), as well as a two-operator technique. Reliability of these techniques has not been described. This study will attempt to validate a novel single operator technique that does not require additional equipment or a second person to assist with stressing the joint. It will also evaluate the reliability of the three described techniques. Healthy volunteers will be recruited to participate in this study. Operators JS and BB will complete stress sonography measurements of the ulnohumeral joint width using a single operator method, a two-operator method, and the Telos Medical Stress test device and compare the results for validation purposes. Intrarater and interrater reliability of these techniques will be also be assessed.
