Shoulder Arthroscopy

Common Shoulder Arthroscopy Procedures for Shoulder Impingement    

Post-Surgical Rehabilitation following Should Arthroscopy

Shoulder Arthroscopy is a surgical procedure used to address conditions and injuries such as shoulder impingement.

This procedure reduces tissue damage, only requires small incisions, and may speed up healing time.  After your shoulder arthroscopy, you may be put in an immobilizer or sling and be restricted in some movements.  After working with a physical therapist, you should be able to resume normal activities.

The shoulder is a very complex piece of machinery.  Its elegant design gives the shoulder joint great range of motion, but not much stability.  As long as all the parts are in good working order, the shoulder can move freely and painlessly.

Shoulder Impingement

Many people refer to any pain in the shoulder as bursitis.  The term bursitis really only means that the part of the shoulder called the bursa is inflamed.  Tendinitis is when a tendon gets inflamed.  This can be another source of pain in the shoulder.  Many different problems can cause inflammation of the bursa or tendons.  Impingement syndrome is one of those problems.  Impingement syndrome occurs when the rotator cuff tendons rub against the roof of the shoulder, the acromion.

Why do I have problems with shoulder impingement?

Usually, there is enough room between the acromion and the rotator cuff so that the tendons slide easily underneath the acromion as the arm is raised.  But each time you raise your arm, there is a bit of rubbing or pinching on the tendons and the bursa.  This rubbing or pinching action is call impingement.

Impingement occurs to some degree in everyone's shoulder.  Day-to-day activities that involve using the arm above shoulder level cause some impingement.  Usually it doesn't lead to any prolonged pain.  But continuously working with the arms raised overhead, repeated throwing activities, or other repetitive actions of the shoulder can cause impingement to become a problem.  Impingement becomes a problem when it causes irritation or damage to the rotator cuff tendons.

Raising the arm tends to force the humerus against the edge of the acromion.  With overuse, this can cause irritation and swelling of the bursa.  If any other conditions decreases the amount of space between the acromion and the rotator cuff tendons, the impingement may get worse.

Bone spurs can reduce the space available for the bursa and tendons to move under the acromion.  Bone spurs are bony points.  They are commonly caused by wear and tear of the joint between the collarbone and the scapula, called the acromioclavicular (AC) joint.  The AC joint is directly above the bursa and rotator cuff tendons.

In some people, the space is too small because the acromion is oddly sized.  In these people, the acromion tilts too far down, reducing the space between it and the rotator cuff.

if you are still having problems after trying non-surgical treatments, your doctor may recommend surgery. 

Common Shoulder Arthroscopy Procedures for Shoulder Impingement

Subacromial Decompression

The goal of surgery is to increase the space between the acromion and the rotator cuff tendons.  Taking pressure off the tissues under the acromion is called subacromial decompression.  The surgeon must first remove any bone spurs under the acromion that are rubbing on the rotator cuff tendons and bursa.  Usually the surgeon also removes a small part of the acromion to give the tendons even more space.  In patients who have a downward tilt of the acromion, more of the bone may need to be removed.  Surgically cutting and shaping the acromion is call acromioplasty. It gives the surgeon another step to get pressure off (decompress) the tissues between the humerus and the acromion.

Resection Arthroplasty

Impingement may not be the only problem in an aging or overused shoulder.  It is very common to also see degeneration from arthritis in the AC joint.  If there is reason to believe that the AC joint is arthritic, the end of the clavicle may be removed during impingement surgery.  This procedure is call resection arthroplasty.

The most common procedure for AC joint osteoarthritis is resection arthroplasty.  A resection arthroplasty involves removing a small portion of the end of the clavicle.  This leaves a space between the acromion (the piece of the scapula that meets your shoulder) and the cut end of the clavicle, where the joint used to be.  Your surgeon will take care not to remove too much of the end of the clavicle to prevent any damage to the ligament holding the joint together.  Usually only a small portion is removed, less than one centimeter.  As your body heals, the joint is replaced by scar tissue.  Remember, the AC joint doesn't move much, but it does need to be flexible.  The scar tissue allows movement but stops the bone ends from rubbing together.

The procedure can be done in two ways.   Today, it is more common to do this procedure using the arthroscope.  An arthroscope is a slender tool with a tiny TV camera on the end.  It lets the surgeon work in the joint through a very small incision.  This may result in less damage to the normal tissues surrounding the joint, leading to faster healing and recovery time.

Arthroscopic Procedure

Today, acrommioplasty is usually done using an arthroscope.

An arthroscope is a special type instrument designed to look into a joint, or other space, inside the body.  The arthroscope itself is a slender metal tube smaller than a pencil.  Inside the metal tube are special strands of glass called fiber optics.  These small strands form a lens that allows one to look into the tube on one end and see what is on the other side - inside the space.  This is similar to a microscope or telescope.  In the early days of arthroscopy, the surgeon actually looked into one end of the tube.  Today, the arthroscope is attached to a small TV camera.  The surgeon can watch the TV screen while the arthroscope is moved around in the joint.  Using the ability to see inside the joint, the surgeon can then place other instruments into the joint and perform surgery while watching what is happening on the screen.

The arthroscope lets the surgeon work in the joint through a very small incision.  This may result in less damage to the normal tissues surrounding the joint, leading to faster healing and recovery.  Once your surgeon is done with the arthroscope, you may be able to go home the same day.

To perform the acromioplasty using the arthroscope, several small incisions are made to insert the arthroschope and special instruments needed to complete the procedure.  These incisions are small, usually about one-quarter inch long.  It may be necessary to make three or four incisions around the shoulder to allow the arthroscope to be moved to different locations to see different areas of the shoulder.

A small plastic, or metal, tube is inserted into the shoulder and connected with sterile plastic tubing to a special pump.  An other small tube allows the fluid to be removed from the joint.   This pump continuously fills the shoulder joint with sterile saline (salt water) fluid.  This constant flow of fluid through the joint inflates the joint and washes any blood and debris from the joint as the surgery is performed.

There are many small instruments that have been specially designed to perform surgery in the joint.  Some of these instruments are used to remove torn and degenerative tissue.  Some of these instruments nibble away bits of tissue and them vacuum them up from out of the joint.  Others are designed to burr away bone tissue and vacuum it out of the joint.  These instruments are used to remove any bone spurs that are rubbing on the tendons of the shoulder and smooth the under surface of the acromion and AC joint.

Post-Surgical Rehabilitation following Shoulder Arthroscopy.

Rehabilitation after shoulder surgery can be a slow process. You will probably need to attend physical therapy sessions for several weeks, and you should expect full recovery to take several months.  Getting the shoulder moving as soon as possible is important.  However, this must be balanced with the need to protect the healing muscles and tissues.

Your surgeon may have you wear a sling to support and protect the shoulder for a few days after surgery.  Ice and electrical stimulation treatments may be used during your first few therapy sessions to help control pain and swelling from the surgery.  Your therapist may also use massage and other types of hands-on treatment to ease muscle spasm and pain.

Therapy can progress quickly after a simple arthroscopic procedure.  Treatments start out with range-of-motion exercises and gradually work into active stretching and strengthening.   You just need to be careful to avoid doing too much, too quickly.

Therapy goes slower after open surgery in which the shoulder muscles have been cut.  Therapists will usually wait up to two weeks before starting range-of-motion exercises.  Exercises begin with passive movement. During passive exercises, your shoulder joint is moved but your muscles stay relaxed.  Your therapist gently moves your joint and gradually stretches your arm.  You may be taught how to do passive exercise at home.

Active therapy starts four to six weeks after surgery.  You use your own muscle power in active range-of-motion exercise.  You may begin with light isometric strengthening exercises.  These exercises work the muscles without straining the healing tissues.

At about six weeks you start doing more active strengthening.  Exercises focus on improving the strength and control of the rotator cuff muscles and the muscles around the shoulder blade.  Your therapist will help you retrain these muscles to keep the ball of the humerus in the socket.  This helps your shoulder move smoothly during all your activities.

Some of the exercises you'll do are designed to get your shoulder working in ways that are similar to your work tasks and sport activities.  Your therapist will help you find ways to do your tasks that don't put too much stress on your shoulder.   Before your therapy sessions end, your therapist will teach you a number of ways to avoid future problems.
