Destot was a leading pioneer in radiology, a pupil of Ollier, an anatomist, and researcher who followed in the experimental medicine tradition of Claude Bérnard. This work is an extensive, in depth, look at the life and work of Étienne Destot. On February 5, 1896, he began performing X-ray examinations, less than two months after Roentgen's discovery! His pioneering work described a space bordered by the hamate, capitate, triquetrum, and lunate; this space is now known as Destot's space. Tanton stated that Destot was the first to reveal the mechanism of fractures of the posterior margin of the distal tibia and to emphasize their clinical relevance; in honor of this contribution, Tanton named such a fracture the “fracture of Destot.” Moreover, Destot is credited with being the first physician to use the term “pilon” in the orthopedic literature. He first described fractures of the scaphoid in 1905. He also described superficial hematomas, Destot's sign, located above the inguinal ligament or in the scrotum or thigh. Such hematomas are indicative of pelvic fractures. Destot is credited with inventing or improving many pieces of medical equipment (e.g., Lambotte's screw plates, anastomotic boutons for the digestive tube, monopolar endocavital radiological tubes). He was also active in developing technical aspects of equipment (e.g., radioscopic examination of the heart, a prototype of the mobile radiological laboratory). Étienne Destot is best known as a radiologist; however, his influence extends well beyond this field. He was an anatomist and surgeon, the founder of radiology in Lyon, prosector, physician, electrician, researcher, and artist.
