Lipomyelomeningocele is one of the more common forms of occult spinal dysraphism seen in clinical practice. It is now universally accepted that prophylactic surgery is indicated in most cases, but areas of controversy remain. These include the diagnosis and management of retethering, the value of intraoperative physiological monitoring, and indications for surgery in stable adults and when the conus is in the normal position.
