Intraarticular Lumbar Joint Corticosteroid Injection(s) as a Treatment of Chronic Low Back Pain in a Selected Population

Descrição detalhada
Subjects will have failed conservative treatment, including, but not limited to oral medications, physical therapy, chiropractic treatment, and/or alternative medicine. They will be evaluated by a spine specialist in the Spine Division of the Department of Orthopaedics and will be schedule for a medial branch block as standard of care. As part of usual and standard care, patients will undergo lumbar medial branch blocks for diagnosis of zygapophysial joint pain.
Patients who obtain ≥ to 80% relief of their index pain with a first set of lumbar medial branch blocks will be offered the opportunity for possible inclusion in the study if they are scheduled to receive a second medial branch block. The definition of a positive response to MBB's is an 80% reduction in pain (by change in NPR scores or estimated patient improvement) AND the restoration of the ability to perform at least one previously painful posture, movement, or activity without increase in pain, during the anesthetic phase of the blocks. If subjects are unable to render NPR scores or percentage estimate of improvement, then a 5 point global perception of effect tool will be used.
