The infraspinatus is nestled in the infraspinous fossa of the scapula and attaches the greater tubercle of the humerus. With muscle fibers running horizontally, infraspinatus works with teres minor in external rotation, adduction and stabilization of the shoulder. It is one of four rotator cuff stabilizing muscles along with supraspinatus, teres minor and subscapularis. Infraspinatus is the second most common culprit of rotator cuff problems and can be a contributor in frozen shoulder. Pitching, pulling a lawn mower cord and even side sleepers whose arms are externally rotated and under head are actions that contribute to injury and overuse. The infraspinatus can be very tender and get little caring attention.
