Elbow Epicondylitis/Epicondylosis describes acute and chronic inflammation of the muscles of the forearm that attach at the elbow that become inflamed. The inflammation occurs both at the periosteum (connective tissue covering of the bone) as well as the muscles and tendons that insert on the bone. Many times, the biomechanical problem is in the shoulder and/or wrist. Conservative management in most cases will decrease the pain, improve function and prevent reoccurrences.
