Diagnosing UCL Tears

In this video, Dr. Grant H. Garcia details the clinical approach, physical examination maneuvers, and diagnostic pitfalls when evaluating ulnar collateral ligament (UCL) tears in the elbow.

Here is a summary of the core medical insights he shares:

• Surgical Nuance by Patient Type: Even when an MRI clearly reveals a frank (complete) UCL rupture, the treatment path depends heavily on the patient's lifestyle. While high-level overhead athletes and throwers usually require surgery to return to their sport, surgical intervention is generally avoided for the general, non-throwing population.
• Physical Exam Testing: To accurately assess the integrity of the ligament and evaluate the degree of medial joint opening, Dr. Garcia performs specialized stress testing, including the classic "milking maneuver," to measure how the elbow handles valgus (inward) force.
• The Overlapping Complexities of "Thrower's Elbow": Dr. Garcia cautions that pain on the inside of the elbow isn't always a simple UCL issue. Overhead athletes often suffer from a combination of overlapping problems, including micro-instability, flexor tendon strains, or the formation of painful bone spurs (osteophytes), all of which must be carefully differentiated during an exam.
• Age-Specific Traps (Under 16): For young athletes under the age of 16, specialists must be exceptionally vigilant. Because their skeletal structures are still growing, a youth player might actually suffer a growth plate injury or pull off a piece of the growth plate (an avulsion) rather than tearing the ligament itself. Dr. Garcia notes that these growth plate injuries can mimic a UCL tear on exams but often require distinct surgical treatment to heal properly.
