Patient Positioning
Patient seated, arm in external rotation while keeping the elbow slightly flexed or extended resting on the examination table (pillow). Better position to check the ligament: patient supine, arm externally rotated, shoulder abducted and elbow flexed (90°)
Probe Positioning
Place the transducer with the cranial edge over the medial epicondyle and move the distal edge over the ulna.
Note: Use passive valgus stress to check the ligament – it may show joint space widening.
