• Symptomatic lumbar canal stenosis is common between lumbar vertebra 4-5 and 3-4. The patient often presents with neurogenic claudication or pseudoclaudication. In Latin, Claudicate means “to limp”. The patient with lumbar spinal stenosis presents with discomfort and pain in the buttock, hip, thigh or leg, which is mostly unilateral and the pain comes usually when standing or walking and it is reduced when squatting, sitting or lying down. • There may be numbness or tingling sensation in the leg while walking. • Some patients may get weakness of the leg while walking which becomes normal on taking rest. • The cause for the pain, numbness and weakness is due to the reduced blood supply to the spinal nerve roots due to the compression of the blood vessels because of narrow spinal canal.
