Pem On Shoulder Arthroscopy

Arthroscopy is a procedure that orthopaedic surgeons use to inspect, diagnose, and repair problems inside a joint.

The word arthroscopy comes from two Greek words, “arthro” (joint) and “skopein” (to look). The term literally means “to look within the joint. During shoulder arthroscopy, your surgeon inserts a small camera, called an arthroscope, into your shoulder joint. The camera displays pictures on a television screen, and your surgeon uses these images to guide miniature surgical instruments.

Because the arthroscope and surgical instruments are thin, your surgeon can use very small incisions (cuts), rather than the larger incision needed for standard, open surgery. This results in less pain for patients, and shortens the time it takes to recover and return to favorite activities.



ANATOMY

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).

  • Ball and socket: 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.
  • Shoulder capsule: The joint is surrounded by bands of tissue called ligaments. They form a capsule that holds the joint together. The under surface of the capsule is lined by a thin membrane called the synovium. It produces synovial fluid that lubricates the shoulder joint.
  • Rotator cuff: 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.
  • Bursa: It is a lubricating sac 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 IS SHOULDER ARTHROSCOPY RECOMMENDED

Your doctor may recommend shoulder arthroscopy if you have a painful condition that does not respond to nonsurgical treatment. Nonsurgical treatment includes rest, physiotherapy, 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.

PLANNING FOR SURGERY

Your orthopaedic surgeon will review your medical and surgical history, including current medications to make sure that you do not have any medical problems that need to be addressed before your surgery. Blood tests, an electrocardiogram, or chest x-ray may be needed to safely perform your surgery.

If you have certain health risks, a more extensive evaluation may be necessary before your surgery. Be sure to inform your orthopaedic surgeon of any medications or supplements that you take. You may need to stop taking some of these prior to surgery.

The Orthopedic surgeon will explain you the specific details about your procedure. Make sure to follow the instructions on when to arrive and especially on when to stop eating or drinking prior to your surgery.
You will be asked to sign a consent form that says you understand the risks of arthroscopy and agree to have the procedure done. Talk to your doctor about any concerns you have regarding the need for the procedure, its risks, how it will be done.

Before the operation, the anesthetist will talk with you about anesthesia options. Many surgeons combine nerve blocks with sedation or a light general anesthetic because patients can become uncomfortable staying in one position for the length of time needed to complete the surgery.

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

PROCEDURE

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.

RECOVERY

Postoperative

After surgery, you will stay in the recovery room for 1 to 2 hours before being transferred to the ward. Nurses will monitor your responsiveness and provide pain medication, if needed. During your hospital stay, usually 1 to 2 days you will receive specific instructions and physiotherapy from our physical therapists.

At home

Although recovery from arthroscopy is often faster than recovery from open surgery, it may still take weeks or months 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.

You will most likely need a sling or special immobilizer to protect your shoulder. Your surgeon will discuss with you how long the sling will be needed.

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 physiotherapist to supervise your exercise program.

It is important that you make a strong effort at rehabilitation in order for your surgery to succeed.

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.

Your surgeon will discuss the possible complications with you before your operation.

LONG-TERM OUTCOMES

Because patients have varied health conditions, complete recovery time is different for everyone.
If you have had a minor repair, you may not need a sling and your strength may return after a short period of rehabilitation. You may be able to return to work or school within a few days of your procedure.

It takes longer to recover from more complicated procedures. Although the incisions are small in arthroscopy, extensive damage within the joint can be repaired with the procedure. Full recovery may take several months. Although it can be a slow process, following your surgeon’s guidelines and rehabilitation plan is vital to a successful outcome.
