Shoulder Replacement Surgery
What is Shoulder Joint Replacement?
Total shoulder replacement surgery is performed to relieve these symptoms. 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.
What are the Indications for Shoulder Joint Replacement?
- Severe shoulder pain that restricts daily activities
- Moderate to severe pain during rest
- Weakness and/or loss of motion
Preparation for Shoulder Joint Replacement
Your surgeon reviews your medical history and performs a physical examination of your shoulder to assess the extent of mobility and pain. Imaging tests such as X-ray or MRI (magnetic resonance imaging) are ordered.
Shoulder Joint Replacement Procedure
The upper arm bone (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 gently press- 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 wound is closed.
