TREATED LESIONS

Shoulder Arthroscopy

Anotaion:
Dr. Chanko Chankov

Description:

Your shoulder is a complex joint that is capable of more motion than any other joint in your body. It is made up of three bones: your upper arm bone (humerus), your shoulder blade (scapula), and your collarbone (clavicle).

The head of your upper arm bone fits into a rounded socket in your shoulder blade. This socket is called the glenoid. A slippery tissue called articular cartilage covers the surface of the ball and the socket. It creates a smooth, frictionless surface that helps the bones glide easily across each other.

 

                             

 

The glenoid is ringed by strong fibrous cartilage called the labrum. The labrum forms a gasket around the socket, adds stability, and cushions the joint.

 

The joint is surrounded by bands of tissue called ligaments. They form a capsule that holds the joint together. The undersurface of the capsule is lined by a thin membrane called the synovium. It produces synovial fluid that lubricates the shoulder joint.

 

Four tendons surround the shoulder capsule and help keep your arm bone centered in your shoulder socket. This thick tendon material is called the rotator cuff. The cuff covers the head of the humerus and attaches it to your shoulder blade.

 

                       

 

There is a lubricating sac called a bursa between the rotator cuff and the bone on top of your shoulder (acromion). The bursa helps the rotator cuff tendons glide smoothly when you move your arm.

 

When Shoulder Arthroscopy Is Recommended?

Your doctor may recommend shoulder arthroscopy if you have a painful condition that does not respond to nonsurgical treatment. Nonsurgical treatment includes rest, physical therapy, and medications or injections that can reduce inflammation. Inflammation is one of your body's normal reactions to injury or disease. In an injured or diseased shoulder joint, inflammation causes swelling, pain, and stiffness.

 

                              

 

Injury, overuse, and age-related wear and tear are responsible for most shoulder problems. Shoulder arthroscopy may relieve painful symptoms of many problems that damage the rotator cuff tendons, labrum, articular cartilage, and other soft tissues surrounding the joint.

 

Common arthroscopic procedures include:

Rotator cuff repair

Bone spur removal

Removal or repair of the labrum

Repair of ligaments

Removal of inflamed tissue or loose cartilage

Repair for recurrent shoulder dislocation

 

Less common procedures such as nerve release, fracture repair, and cyst excision can also be performed using an arthroscope. Some surgical procedures, such as shoulder replacement, still require open surgery with more extensive incisions.

 

Preparing for a shoulder arthroscopy

If you smoke you will be asked to stop, as smoking increases your risk of getting a chest and wound infection, which can slow your recovery.

 

The operation is usually done as a day case, which means you wont have to stay in hospital overnight.

 

The operation may be done under general anaesthesia, but it can be combined with local anaesthesia, to give you pain relief after the operation. General anaesthesia means you will be asleep during the operation. Local anaesthetic completely blocks pain from the shoulder area. Sometimes, the whole operation can be done under local anaesthesia, which means you will stay awake during the operation.

 

This means not eating or drinking, typically for about six hours beforehand.

 

Surgical Procedure

Once in the operating room, you will be positioned so that your surgeon can easily adjust the arthroscope to have a clear view of the inside of your shoulder. The two most common patient positions for arthroscopic shoulder surgery are:

 

Beach chair position. This is a semi-seated position similar to sitting in a reclining chair.

Lateral decubitius position. In this position the patient lies on his or her side on an operating table.

 

Once you are positioned, the surgical team will remove hair, if needed, and then spread an antiseptic solution over your shoulder to clean the skin. They will cover your shoulder and arm with sterile drapes, and will most likely place your forearm in a holding device to ensure your arm stays still.

 

 

 

Your surgeon will first inject fluid into the shoulder to inflate the joint. This makes it easier to see all the structures of your shoulder through the arthroscope. Then your surgeon will make a small puncture in your shoulder (about the size of a buttonhole) for the arthroscope. Fluid flows through the arthroscope to keep the view clear and control any bleeding. Images from the arthroscope are projected on the video screen showing your surgeon the inside of your shoulder and any damage.

 

Once the problem is clearly identified, your surgeon will insert other small instruments through separate incisions to repair it. Specialized instruments are used for tasks like shaving, cutting, grasping, suture passing, and knot tying. In many cases, special devices are used to anchor stitches into bone.

 

Your surgeon may close your incisions with stitches or steri-strips (small Band-Aids) and cover them with a large, soft bandage.

 

Most arthroscopic procedures take less than an hour, however, the length of your surgery will depend on what your surgeon finds and what repairs are required.

 

Possible complications

Most patients do not experience complications from shoulder arthroscopy. As with any surgery, however, there are some risks. These are usually minor and treatable. Potential problems with arthroscopy include infection, excessive bleeding, blood clots, and damage to blood vessels or nerves. Most often, these complications are mild, transient and resolved within a few days.

 

Recovery Process

Although recovery from arthroscopy is often faster than recovery from open surgery, it may still take weeks for your shoulder joint to completely recover.

 

You can expect some pain and discomfort for at least a week after surgery. If you have had a more extensive surgery, however, it may take several weeks before your pain subsides. Ice will help relieve pain and swelling. Your doctor may prescribe pain medicine, if needed.

 

      

 

Although it does not affect how your shoulder heals, lying flat may pull on your shoulder and cause discomfort. Some patients are more comfortable sleeping in a reclining chair or propped up in bed during the first days after surgery.

 

Rehabilitation

Rehabilitation plays an important role in getting you back to your daily activities. An exercise program will help you regain shoulder strength and motion. Your surgeon will develop a rehabilitation plan based on the surgical procedures you required.

 

If you have had a more complicated surgical repair, your surgeon may recommend a physical therapist to supervise your exercise program.

 

Benefits of shoulder arthroscopy

Arthroscopy is an alternative to "open" surgery that completely exposes the shoulder joint. Arthroscopy results in less pain and stiffness, fewer complications, shorter (if any) hospital stays, and faster recovery sometimes.

 

Shoulder arthroscopy has been performed since the 1970s. It has made diagnosis, treatment, and recovery from surgery easier and faster than was once thought possible. Improvements to shoulder arthroscopy occur every year as new instruments and techniques are developed.
