Total shoulder replacement surgery is performed to relieve symptoms such as pain, swelling, and stiffness of the shoulder joint (osteoarthritis). In this surgery, the damaged articulating parts of the shoulder joint are removed and replaced with artificial prostheses. Replacement of both the humeral head and the socket is called a total shoulder replacement.
This procedure is done under regional or general anesthesia, and proceeds as follows. An incision is made over the affected shoulder and the underlying muscles are separated to expose the shoulder joint. The humerus is separated from the glenoid socket of the shoulder bone. The arthritic or damaged humeral head is cut and the humerus bone is hollowed out and filled with cement. A metal ball with a stem is pressed to fit into the humerus. Next, the arthritic part of the socket is prepared. The plastic glenoid component is fixed in the shoulder bone. After the artificial components are implanted, the joint capsule is stitched and the would in closed.
Rotator Cuff Arthroscopy
Shoulder arthroscopies are indicated to treat many different shoulder conditions when conservative treatment fails to relieve pain and disability. Some of these conditions include shoulder impingement, rotator cuff tear, frozen shoulder, instability, biceps rupture, bone spurs, damaged cartilage or ligaments, and more.
This surgery is also performed under general or regional anesthesia. Sterile fluid is injected into the shoulder joint to expand the surgical area so the surgeon has a clear view of the damage, as well as allowing for more room to work. A button-sized hole is made in the shoulder, and the arthroscope is inserted. The surgeon can view the inside of the shoulder via the camera attached to the end of the arthroscope. Surgical instruments are introduced into the joint through separate small holes in order to remove and repair damage to the joint.
