title: Positional variability in redundant lumbar nerve-root syndrome.
abstract: A case of redundant lumbar nerve roots associated with lumbar canal stenosis is described. At myelography, the redundant nerve roots proximal to a site of blockage were noted to disappear on flexion and extension while similar redundancy developed distally. The etiology of this condition is discussed along with the differential diagnosis.
