Cortisone Injection Treatment
We are unable to recommend for or against the use of injectable corticosteroids when treating patients with glenohumeral joint osteoarthritis.

Rationale
There is no evidence to support or refute the use of intra-articular steroid injection for the treatment of osteoarthritis of the shoulder, whether performed with or without fluoroscopic, ultrasound or CT guidance.
 
Corticosteroid injections are used widely in clinical practice for patients with shoulder pain of all etiologies, and occasionally they are employed in conjunction with physical therapy as an initial treatment for patients with shoulder pain.  Intra-articular injections are used for the treatment of osteoarthritis in other joints.  The current literature does not support or refute the use of intra-articular steroid injection for the treatment of glenohumeral osteoarthritis.
