Shoulder Impingement

Shoulder Impingement (Rotator Cuff Tendinitis)

The rotator cuff is made up of tendons and muscles that allow for a great range of motion of your arm. This is a frequent source of pain for athletes and an area that is at risk for injury during sporting activities. Shoulder impingement is often referred to as rotator cuff tendinitis and is one of the most common causes of shoulder pain.

What causes rotator cuff tendinitis?
When you raise your arm to shoulder height, the space between the bone and rotator cuff narrows. The bone can rub against (or impinge on the tendon and the bursa, causing irritation and pain when the arm is used repeatedly. Young athletes who use their arms for overhead action are particularly vulnerable. This includes those who play tennis, softball and baseball, and swimmers.

What are the symptoms of shoulder impingement?
When the rotator cuff is irritated this can lead to local swelling and tenderness in the front aspect of the shoulder. You may also have pain and stiffness when you lift your arm. There is also a sensation of tenderness when the arm is lowered from an elevated position. Other symptoms include sudden pain when reaching or lifting, pain radiating from the front of the shoulder to the side of the arm, minor pain at rest, and pain when throwing or using the arm.

How is rotator cuff tendinitis treated without surgery?
Your orthopedic specialist wants to reduce your pain and restore function of your shoulder. He will consider your activity level, your age, and your general state of health. Many times shoulder impingement can be treated with medications and rest. It is not uncommon for athletes to be ordered physical therapy to help restore normal motion of the shoulder. Your therapist will teach you specific stretching and strengthening exercises to relieve your shoulder pain and help you get back to normal activities.

What is involved with surgical treatment?
The goal of surgery is to create more space for the rotator cuff and this involves removing a portion of the inflamed bursa. Your orthopedic specialist will perform an anterior acromioplasty, where part of the bone is removed to allow for movement of the rotator cuff. Many times, the surgeon opts to perform this procedure by way of arthroscope.

The arthroscopic technique allows for use of small thin surgical instruments to be inserted around puncture wounds around the shoulder. The doctor can see inside the shoulder through a small camera inserted into the joint that displays images onto a computer TV monitor.
