This is retrospective study on the lumbar spinal canal stenosis (LSS) which is concerned with the relationship between calcium deposits in the ligamentum flavum and cauda equina syndrome. The distance of intermittent claudication and residual urine volume were used as assessment of the function of cauda equina. Cauda equina syndrome was significantly aggravated in cases of LSS where there was calcium deposits in the ligamentum flavum, as opposed to cases of LSS where there were no such deposits.
