Spinal stenosis is caused by narrowing of the spinal canal or neural foramina producing root ischaemia and neurogenic claudication.1 Stenosis of the spinal canal is most often caused by a combination of loss of disc space, osteophytes and a hypertrophic ligamentum flavum. Not all patients with narrowing develop symptoms. However, the narrowing may progress to cause compression of the spinal nerves and/or spinal cord compression.
