History of Evolution of Posterolateral Approaches to the Thoracic Spine: From Cure of Pott's Disease to Epidural Tumor Resection.

Since the end of the nineteenth century, the wide dissemination of Pott's disease has ignited debates about which should be the ideal route to perform ventrolateral decompression of the dorsal spine in case of paraplegia due to spinal cord compression in tuberculosis spondylitis. It was immediately clear that the optimal approach should be the one minimizing the surgical manipulation on both neural and extraneural structures while optimizing the exposure and surgical maneuverability on the target area. The first attempt was reported by Victor Auguste Menard in 1894, who described, for the first time, a completely different route from traditional laminectomy, called costotransversectomy. The technique was conceived to drain tubercular paravertebral abscesses causing paraplegia without manipulating the spinal cord. Over the following decades, many other routes have been described all over the world, thus demonstrating the wide interest on the topic. Surgical development has been marked by the new technical achievements and by instrumental/technological advancements, until the advent of portal surgery and endoscopy-assisted techniques. In this article, the authors retraced the milestones of this history up to the present days, through a systematic review on the topic.
