The Moving/Dynamic Valgus Test is used to assess injury to which structure?

Explanation:
This test checks the medial elbow stabilizer, the ulnar collateral ligament (UCL), especially its anterior bundle. During throwing, a valgus load is placed on the elbow, stressing the UCL. In the moving valgus maneuver, the clinician starts with the shoulder abducted and externally rotated and the elbow flexed around 90 degrees, then applies a valgus stress while moving the elbow into extension through a wide arc. If the UCL is injured, this stress reproduces medial elbow pain and may reveal instability as the ligament cannot adequately resist the valgus force, typically around the mid-range of motion (approximately 120–70 degrees of flexion). That’s why this test is used to detect UCL injuries. The other options involve structures outside this test’s primary target: a SLAP lesion is a shoulder labrum issue, the rotator cuff is the shoulder tendons, and the radial collateral ligament is on the lateral side of the elbow.
