Unexpected inferior shift found in patients with rotator cuff tears during active elevation

Although recently published results showed no dynamic superior humeral head migration among patients with well-compensated single or two-tendon rotator cuff tears, an unexpected inferior shift during active elevation was found.

Researchers used a custom biplane fluoroscopy system to measure the 3-D position and orientation of the scapula and humerus of 14 patients with full-thickness supraspinatus or supraspinatus and infraspinatus rotator cuff tears and 10 controls during shoulder abduction in a full range of motion.
