This particular procedure is designed for people who have rotator cuff arthropathy or a large, irreparable rotator cuff tear. The rotator cuff is a group of muscles and tendons that surround the shoulder joint and allow you to lift your arm over your head. When this structure is severely torn, shoulder arthritis can set in and mobility is limited.
During this procedure, the surgeon removes damaged bone joint tissue. A smooth, polished, spherical alloy metal “glenosphere” is then fixed to the old bony “cup” of the shoulder, and a stemmed alloy and polymer cup to the shaft of the upper-arm bone.« Back to Glossary Index
