The Alliance Modular Glenoid components are intended for use as a component of the Alliance Glenoid System. The Alliance Modular Glenoid components are intended for shoulder joint arthroplasty. Indications of the Alliance Glenoid System include: 1. Non-inflammatory degenerative joint disease including osteoarthritis and avascular necrosis. 2. Rheumatoid arthritis. 3. Fractures of the proximal humerus, where other methods of treatment are deemed inadequate. 4. Difficult clinical management problems, where other methods of treatment may not be suitable or may be inadequate.
