How do i treat osteolysis of the shoulder?

It depends: I wonder what you mean by osteolysis? At the shoulder, the most common is distal clavicular osteolysis. Assuming this is the diagnosis, let's talk treatment. Therapy will depend on cause: trauma and overuse like weightlifting: limit activity and give body a chance to heal. Nsaids, rheumatoid arthritis: treat RA with fp or rheumatologist hyperparathyroidism: treat with fp or endocrinologist.

Rest: Osteolysis of the shoulder typically refers to distal clavicle osteolysis which is generally from overuse in weightlifters. This often responds well to nsaids, physical therapy, activity modifications, and injections. If it fails to improve with rest and conservative care, surgery may may be needed. This refers to distal clavicle osteolysis, not osteonecrosis of the shoulder.
