What is the purpose of Wright's test?

• A. To assess AC joint pathology.
• B. To assess neurovascular compression in thoracic outlet syndrome.
• C. To evaluate rotator cuff strength.
• D. To test elbow flexion.

Answer: (B)

Wright's test is used to detect neurovascular compression in thoracic outlet syndrome. In this maneuver, the arm is positioned in maximal abduction and often extension or slight external rotation, which narrows the space where the subclavian artery and brachial plexus pass beneath the clavicle and through the pectoralis minor. If compression occurs, the radial pulse may diminish or vanish and neurovascular symptoms in the arm can be reproduced. A positive result points to thoracic outlet syndrome, particularly compression in the costoclavicular or pectoralis minor region. This test targets the thoracic outlet rather than other shoulder or elbow structures like the AC joint or rotator cuff.
