The supraspinatus tendon is a thick fibrous band of tissue that connects the supraspinatus muscle to the shoulder joint. The supraspinatus muscle is attached to the shoulder blade and aids in shoulder movement. The supraspinatus tendon is part of the rotator cuff, and rotator cuff injury or inflammation is a common source of shoulder pain in many...
The Suprascapular Nerve runs through the suprascapular notch to supply the supraspinatus muscle. It further travels through the spinoglenoid notch to innervate the infraspinatus muscle. Damage at the suprascapular notch causes weakness in shoulder abduction and also external rotation, whereas if the nerve is compressed/damaged at the spinoglenoid notch only the infraspinatus muscle and external rotation will be affected.
