TOTAL SHOULDER REPLACEMENT What is shoulder arthritis?
The shoulder joint is a ball and socket joint. The joint
surfaces are normally covered by a smooth cartilage layer. Arthritis is
a degeneration of the joint cartilage. Over time, the cartilage becomes
thin, sometimes to the point that bone rubs on bone inside the joint.
This process eventually leads to bone spurs and painful scar tissue in
and around the shoulder joint.
What are the symptoms and treatments of shoulder arthritis?
The pain associated with shoulder arthritis may be gradual
in onset, or may be worsened by an injury to the shoulder. Symptoms of
shoulder arthritis include stiffness, pain with motion,popping, and
pain at night. The severity of the arthritis can usually be determined
on xray and physical exam. MRI and CT scan can be useful to evaluate
the arthritis as well as other potential causes of shoulder pain.
Initial treatment of shoulder arthritis includes
anti-inflammatory medications, physical therapy, and injections. When
nonoperative treatments do not relieve the pain, surgery may be
necessary.
What is total shoulder replacement?
Shoulder replacement is similar to joint replacement in
other joints such as the knee and hip. The arthritic joint surface of
the humerus is replaced with a metal ball connected to a metal stem
that fits inside the humerus. The arthritic socket is replaced by a
plastic socket that is secured by bone cement. Recovery typically
includes an overnight stay in the hospital and several weeks of
physical therapy. Excellent motion and shoulder function is usually
seen after full recovery.
