Dr. Brian Gay from First Look MRI explains how to read an elbow MRI scan with a UCL tear from from sublime tubercle.

The UCL is rarely stressed in daily activities. It is injured in throwing types of sports or after elbow dislocation or surgery. It may occur as a sudden tear or may gradually stretch out over time with repetitive injury.

When torn, the UCL does not typically heal or may heal in a lengthened position. Sprains are classified into three grades.

In a first-degree sprain, the ligament is not lengthened but is painful. With a second-degree sprain, the ligament is stretched but still functions. With a third-degree sprain, the ligament is torn and does not function.
