Shoulder replacement surgery provides a new metal ball for the humerus and a new plastic liner for the glenoid. Many times, the ball is much more severely worn than the socket. The metal ball which replaces the humeral head is anchored to the humerus by a stem which fits into the canal of the humerus.
Patients are typically in the hospital for two to three days after surgery.
Many express very rapid relief of symptoms in the arthritis shoulder.
