Compression-rotation test for SLAP lesion

To perform the compression-rotation test, the patient lays supine with their shoulder abducted 90 degrees directly to the side and their elbow flexed at 90 degrees. The examiner pushes the humerus into the glenoid by applying an axial load and then rotates the humerus internally and externally. A positive test produces a catching, popping, or snapping sensation.
