Rotator Cuff
Description[edit | edit source]
Rotator cuff is a common name for the group of 4 muscles and their tendons that provide strength and stability during motion of the shoulder. The muscles arise from the scapula and connect to the head of the humerus, forming a cuff at the glenohumeral joint.
Anatomy[edit | edit source]
The rotator cuff muscles include:
| Origen on scapula | Insertion on humerus | Primary function | |
|---|---|---|---|
| M. supraspinatus | supraspinous fossa | superior facet of greater tuberosity | abduction |
| M. infraspinatus | infraspinous fossa | middle facet of greater tuberosity | exorotation |
| M. teres minor | lateral border of scapula | inferior facet of greater tuberosity | exorotation |
| M. subscapularis | subscapular fossa | lesser tuberosity or humeral neck | endorotation |
The rotator cuff muscles are used in a variety of upper extremity movements including flexion, abduction, internal rotation and external rotation.
Cranial to the rotator cuff, there is a bursa that covers and protects the muscle tendons as they are in close contact to the surrounding bones.
Common injuries to the rotator cuff[edit | edit source]
• primary impingement
• secondary impingement
• degenerative anatomical changes
• tendonitis
• rotator cuff tears
