title: Pathological and myelographic changes in the major types of lumbar spinal stenosis.
abstract: Correlated pathological and myelographic observations suggest that the combined types of lumbar spinal stenosis appear to be the most common. The posterior articular processes play the greatest part in producing narrowing--the inferior facet narrowing the central canal and the superior facet narrowing the nerve root canal.
