Cauda Equincs Compression is rare in spondylolisthesis. Between 1975 and 1978, five patients have been treated/or cauda equina compression caused by spondylolisthesis with an intact neural arch. In all the cases cauda equina was trapped and compressed by dislocation of the vertebral bodies and intrusion of laminae resulting in severe neurological signs ranging from absent ankle jerks, weakness and atrophy of the anterior tibial muscles and minor sensory loss to paraparesis and incontinence. A complete myelographic block was present in all the cases. Treatment, in all the cases, consisted of decompressive laminectomy combined with bilateral postero-lateral fusion—.–the fusion mass extending from the sacrum to the fourth transverse process. Excellent results were obtained by using this combined procedure. Sciatica and back pain was relieved in all the cases and there was marked improvement in neurological signs in 4. No patient was made worse by this combined procedure. Technique and results of this treatment in five patients with nerve root and cauda equina compression due to spondylolisthesis are discussed.
