Cervical myelopathy. Technique and results of spinal cord decompression by lateral laminectomy.

The Authors describe the technique of lateral laminectomy devised by Gui in 1965 for the treatment of cervical myelopathy secondary to cervical spondylosis. Spinal cord decompression is obtained by a lateral laminectomy with the maximum saving of bone, ligaments and muscles of the cervical spine. CAT scan demonstrated very well the effective decompression of the spinal cord achieved with this technique. The results of 87 cases treated in this way between 1968 and 1980 are reported. The average follow-up was 2.5 years. There was an improvement in the neurological symptoms in 82% of the cases.
