## Indications for use
The Zimmer Trabecular Metal Shoulder System is indicated for the following: Hemiarthroplasty/Anatomic application: - the treatment of severe pain or significant disability in degenerative, rheumatoid, or traumatic disease of the glenohumeral joint; - ununited humeral head fractures of long duration; - irreducible 3-and 4-part proximal humeral fractures; - avascular necrosis of the humeral head, or other difficult clinical management problems where arthrodesis or resectional arthroplasty is not acceptable. Reverse application: - the treatment of severe pain or significant disability in degenerative, rheumatoid, or traumatic disease of the glenohumeral joint; - ununited humeral head fractures of long duration; - irreducible 3-and 4-part proximal humeral fractures; - avascular necrosis of the humeral head, or other difficult clinical management problems (such as a failed total shoulder arthroplasty or grossly rotator cuff deficient joint) where arthrodesis or resectional arthroplasty is not acceptable. 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 are intended for either cemented or uncemented use. The reverse base plate is intended for uncemented use, and requires two screws for initial fixation. When used in a total shoulder application, the all-polyethylene glenoid components are intended for cemented use only. In the USA, the Trabecular Metal Glenoid must be cemented under the base (see surgical technique for details) or fully cemented in place.
