Jacques Forestier: Forgotten Contributions of a Rheumatologist to Spine Surgery.

Jacques Forestier (1890-1978) was a well-known rheumatologist and radiologist whose innovations have revolutionized spinal neurosurgery and rheumatology. He was well known as "Doctor Lipiodol" for his accidental discovery of spinal myelography, which he later extrapolated for use in many body cavities and their pathologies. He was the first to describe "senile ankylosing hyperostosis of the spine," which was later renamed "diffuse idiopathic skeletal hyperostosis." Furthermore, he is credited with the first use of gold salts as a disease-modifying therapy for rheumatoid arthritis. We have presented a historical vignette to chronicle the life of Jacques Forestier and his contributions to the field of spinal neurosurgery.
