Video Summary
Ryan Hubbard provides an ultrasound consult on the ulnar collateral ligament (UCL) of the elbow, focusing on diagnosing tears. The anterior bundle of the UCL is the main stabilizer of the medial elbow and is examined using patient positioning and a high-frequency linear transducer. A normal UCL appears with linear, homogenous fibers. Tears are identified by fibrous thickening, heterogeneity, and hypoechogenicity. Stress views, alongside the milking maneuver, assess gapping at the humeral-ulna joint for pathology, with gaps over two millimeters indicating a possible tear. The consult concludes with an analysis of visible ligament defects and dynamic instability.
