Joint replacement involves surgery to replace the ends of bones in a damaged joint. This surgery creates new joint surfaces.
In shoulder replacement surgery, doctors replace the ends of the damaged upper arm bone (humerus) and usually the shoulder bone (scapula) or cap them with artificial surfaces lined with plastic or metal and plastic. Shoulder joint components may be held in place with cement. Or they may be made with material that allows new bone to grow into the joint component over time to hold it in place without cement.
Dr Chanda specializes in elective orthopaedic surgeries like arthroscopic surgery for shoulder ligament tear and other shoulder sports injuries. Shoulder is the most complex of all the joints in the body and only few arthroscopic surgeons specialize in the arthroscopic repair of the shoulder ligaments. Shoulder replacement is not a very common surgery and should be done by the expert surgeons. Dr Debashish has expertise in all the joint replacements like Shoulder, Hip and Knee Joint.
The top end of your upper arm bone is shaped like a ball. Muscles and ligaments hold this ball against a cup-shaped part of the shoulder bone. Surgeons usually replace the top of the upper arm bone with a long metal piece, inserted into your upper arm bone, that has a rounded head. If the cup-shaped surface of your shoulder bone that cradles your upper arm bone is also damaged, doctors smooth it and then cap it with a plastic or metal and plastic piece.
Surgeons are now trying a newer procedure called a reverse total shoulder replacement for people who have painful arthritis in their shoulder and also have damage to the muscles around the shoulder. This is the best way to get rid of this problum. In this procedure, after the surgeon removes the damaged bone and smooths the ends, he or she attaches the rounded joint piece to the shoulder bone and uses the cup-shaped piece to replace the top of the upper arm bone. Early results are encouraging. This surgery is not right for everyone. And not all surgeons have done it. Success depends not only on careful evaluation to be sure it's the best & right surgery for you but also on having a surgeon with experience in reverse shoulder replacement.
Doctors often use general anesthesia for joint replacement surgeries. This means you'll be unconscious during surgery. But sometimes they use regional anesthesia, which means you can't feel the area of the surgery and you are sleepy, but you are awake. The choice of anesthesia depends on your doctor, on your overall best health, and, to some degree, on what you prefer.
Your doctor may recommend that you take antibiotics before and after the surgery to reduce the risk of infection. If you need any major dental work, your doctor may recommend that you have it done before the surgery. Infections can spread from other parts of the body, such as the mouth, to the artificial joint and cause a serious problem.
Rehabilitation (rehab) after a shoulder replacement starts right away. It is not too demanding early on, but it is very important that you do it. Most doctors will not allow you to use the shoulder muscles for several weeks after surgery. The main goal of rehab is to allow you to move your shoulder as far as possible so it's easier for you to do daily activities, such as dressing, cooking, and driving. Most people eventually regain about two-thirds of normal shoulder motion after surgery. But other things that affect how much movement you get back after surgery are how much movement you had before surgery and whether the soft tissues around your shoulder were also damaged. It is very important that you take part in physical therapy both while you are in the hospital and after you are released from the hospital to get the most benefit from your surgery.
Most people go home 1 to 3 days after surgery. Some people who need more extensive rehab or those who don't have someone who can help at home go to a specialized rehab center for more treatment.
