Dynamic sonography with valgus stress to assess elbow ulnar collateral ligament injury in baseball pitchers

Skeletal Radiol. 2002 Nov;31(11):671-6. doi: 10.1007/s00256-002-0558-0. Epub 2002 Aug 21.


Sonography is a valuable method for imaging superficial tendons and ligaments. The ability to obtain comparison images easily with dynamic stress allows assessment of ligament and tendon integrity. We studied the medial elbow joints of two baseball pitchers using MR imaging and dynamic sonography. Both sonography and MR imaging identified the ulnar collateral ligament tears. Dynamic sonography uniquely demonstrated the medial joint instability.
