Utilization of sonography and a stress device in the assessment of partial tears of the ulnar collateral ligament in throwers.

The non-invasive assessment of medial elbow pain in throwers can be challenging. Valgus stress transmitted to the elbow during the late cocking and acceleration phases of the throwing motion can result in injury to the medial ligamentous structures of the elbow, bony surfaces, and common tendon of the forearm flexors. The utilization of musculoskeletal (MSK) ultrasound in combination with the Telos Stress Device (TSD) (Austin & Associates Fallston, MD) can be an alternate quick assessment when radiography is not be available.
