Spinal stenosis is the narrowing of the central channel in the spine that contains the spinal cord and nerve roots often as a result of a minor disc bulge, inflammation of the face joints or thickening of the ligamentum flavum. This tends to occur in patients over 55 and presents with pain the back, buttocks or legs when standing or walking. The pain is burning whilst walking but quickly stops on resting. Early MRI is important and image guided spinal procedures can alleviate symptoms. Surgery may be required in severe cases.
