Addiction to cortisone was the subject of the 1956 motion picture, Bigger Than Life , produced by and starring James Mason . Though it was a box-office flop upon its initial release,  many modern critics hail it as a masterpiece and brilliant indictment of contemporary attitudes towards mental illness and addiction.  In 1963, Jean-Luc Godard named it one of the ten best American sound films ever made.  John F. Kennedy needed to regularly use corticosteroids such as cortisone as a treatment for Addison's Disease . 
Radiofrequency ablation is a procedure used to treat severe, chronic back pain usually in the lower (lumbar) back area. This procedure is also commonly referred to as “radiofrequency nerve ablation,” “rhizotomy,” or “facet rhizotomy.” The procedure involves ablating the medial branch nerves that carry pain signals from the facet joint using heat generated from high-frequency-alternating currents (an electrode). The procedure can be done using a local anesthetic rather than a general anesthetic, and a mild sedative is often used to reduce any patient anxiety.
Between 1992 and mid 1996, we found one hundred and nine patients with coccygeal instability. They were treated conservatively (intradiscal injection). Thirty-one who did not respond and were severely disabled were offered surgery. Twenty-eight of the 31 surgical patients were followed up for more than one year. They had had pain for an average of 31 months. The dynamic films showed 17 luxations, and 11 hypermobility. The procedure was confined to the removal of the mobile bony element. The mean postoperative follow-up was 29 months (range: 12-53 months). Patients were assessed using a visual analogue scale, a verbal scale, and a clinical examination.
