Clinical Indications • Osteoarthritis • Inflammatory Arthritis • Osteonecrosis • Rotator Cuff Arthropathy • Fracture • Tumor
INDICATIONS • GLENOHUMERAL JOINT ARTHRITIS RESULTING IN: • PAIN • LOSS OF MOTION • LOSS OF FUNCTION
OTHER TREATMENT OPTIONS • ACTIVITY MODIFICATION • NSAIDS/TOPICAL ANALGESICS • PT* • USUALLY ELICITS PAIN • INJECTIONS • CORTISONE • HYALURONIC ACID • ARTHROSCOPY • FUSION
Other Options: Fusion • Young • Heavy Laborer • Poor function of Rotator Cuff and Deltoid • Infection • Decreasing Indications
