Trepanation Was a Bloodcurdling Form of Neurosurgery
Trepanation comes from the Greek word "trypanon" which means "to bore." It is humanity's oldest form of surgery and involves the drilling of a hole in the skull. According to reports, the procedure was done on individuals who were fully conscious or unanesthetized: "Even though there was knowledge of anesthesia, and there were mixtures used to put patients into a deep sleep, they were very risky. Sometimes the mixture involved too much hemlock and the patient never woke up. In some cases, physicians opted to skip the risk involved with anesthesia."
New Spinal Cord Stimulation Procedure Makes it Possible for Paralyzed People to Walk Again Just One Day Post-Surgery
New research shows electrode devices implanted along spinal cord enables paralyzed individuals to walk independently and to feel again. Scientists have been working on spinal cord stimulation as a means of overcoming paralysis for over 30 years. While there has been some limited success in the past, this research was innovative as it used redesigned technology originally applied to alleviate pain to successfully target nerve roots. When turned on, the device makes it possible for patients suffering from paralysis resulting from severe spinal cord damage to take their first steps since their injury.
