Canal stenosis is now the most com mon indication for lumbar spine surgery in elderly patients and is increasing in frequency parallel to aging of the popu lation. It is generally accepted that surgery is indicated if a well-conducted conservative management fails and is usually followed by a quick recovery and improvement.
