The mean age of onset in narrow spinal canal is in the fourth decade and the onst of symptoms is in the later years than the heniated discs. The interval between onset of symptoms and operation in narrow spinal canal is in the later years than the heniated d[sc.
2) Bilateral leg pains are more common in the narrow lumbar spinal canal.
3) The nerve root pain in the patient with a herniated disc tends to be more acute and more localized whereas in the narrow lumbar spinal canal is more chronic and less specific in the localization.
4) Symptoms and signs of involvement of the higher nerve root and more than one root would be more suggestive of a narrow lumbar spinal canal. Intermittent claudication of cauda equina is more common in the narrow lumbar spinal canal.
