## Indications for use
Hemiarthoplasty/Conventional Total Application: * Non-inflammatory degenerative joint disease including osteoarthritis and avascular necrosis. * Rheumatoid arthritis. * Correction of functional deformity. * Fractures of the proximal humerus, where other methods of treatment are deemed inadequate. * Difficult clinical management problems, including cuff arthropathy, where other methods of treatment may not be suitable or may be inadequate. Optional use in revision: in some medical conditions (e.g. revision when healthy and good bone stock exists), the surgeon may opt to use primary implants in a revision procedure. Reverse Application: Zimmer Biomet Reverse Shoulder products are indicated for use in patients whose shoulder joint has a grossly deficient rotator cuff with severe arthropathy and/or previously failed shoulder joint replacement with a grossly deficient rotator cuff. The patient must be anatomically and structurally suited to receive the implants and a functional deltoid muscle is necessary. The Zimmer Biomet Reverse Shoulder is indicated for primary, fracture, or revision total shoulder replacement for the relief of pain and significant disability due to gross rotator cuff deficiency. The assembled humeral component may be used alone for hemiarthroplasty or combined with the glenoid component or reverse components for total shoulder arthroplasty (conventional or reverse applications). The humeral components may be used cemented or uncemented (biological fixation). The Titanium Humeral Head and Glenosphere components are indicated for patients with suspected cobalt alloy sensitivity. The wear properties of Titanium and Titanium alloys are inferior to that of cobalt alloy. A Titanium humeral head or Glenospheres is not recommended for patients who lack suspected material sensitivity to cobalt alloy.
