Central stenosis predominantly results from hypertrophied ligamentum flavum but sometimes can be the result of mild flavum hypertrophy in combination with small contained disc herniation or rarely congenital stenosis superimposed with some flavum hypertrophy or diffuse idiopathic skeletal hypertrophy syndrome. In either case the choice of approach remains constant i.e. interlaminar and the presenting complaint determines the extent of decompression. A patient with central stenosis can present with predominant unilateral radicular leg pain or bilateral neurologic claudication. In our experience for central stenosis with unilateral radiculopathy, central with symptomatic side decompression is usually sufficient, but a patient with bilateral symptoms needs contra-lateral decompression as well.
