With aging there is degeneration of intervertebral disc and facet joints. This reduces the space available for the nerves going into legs. As a result patient experiences heaviness in legs after walking and has to stand or stoop forwards. The symptoms recur after walking similar distance. This symptom is called claudication. Patients may also experience tingling or numbness in legs. X-rays reveal changes of degeneration. MR Scans show reduced space available for nerves. Non- operative treatment consists of exercises, caudal epidural injections and analgesics. If activity is limited due to symptoms, spinal surgery is advised. Surgery is called spinal decompression, wherein space for the nerves is increased, by removing the structures pressing on the nerves. Following surgery, patient’s walking distance improves.
