Rotator Cuff Physical Exam
Musculoskeletal physical examination is important in diagnosing muscle injury. One of the most common muscle problems is injury to rotator cuff muscles. At our Beverly Hills medical office, experts perform rotator cuff physical exam to check the stability of your shoulder joint.
What is rotator cuff?
The rotator cuff is a group of 4 muscles that protect and stabilize the shoulder joint. Muscles of the rotator cuff include supraspinatus, infraspinatus, subscapularis, and teres minor. The tendons of these muscles insert in your humerus, or upper arm bone, and cover your shoulder joint, securing its stability. They also enable you to rotate and lift your arm smoothly.
What is rotator cuff injury?
Injury to rotator cuff muscles is a common cause of shoulder pain in adults. A rotator cuff tear means that one of the tendons of the rotator cuff muscles is torn, resulting in pain and limited movement of the shoulder joint. A tear in rotator cuff muscles, most commonly affecting the supraspinatus muscle, has two types.
Types of rotator cuff tears
1. Partial (or incomplete) tear: tendon is damaged but not fully torn
2. Full thickness (or complete) tear: tendon is fully torn and the muscle is no longer bound to the bone
