Thecaloscopy: the endoscopy of the lumbar subarachnoid space, part I: historical review and own cadaver studies.
Since 1931 only a few efforts have been made for direct visualization of the neural structures of the spinal canal. Given current technologies and minimally invasive techniques it is now possible to effectively view these structures. We describe here a new technique for inspection of the subarachnoid space of the lumbar spinal canal by using a flexible endoscope in ten fresh post-mortem adult human cadavers. According to the anatomical structures, namely the thecal sac and its anatomical position, the procedure is called thecaloscopy and the instrument is a thecaloscope. It was proven that the procedure is safe and easy to perform.
