62 cases of cervical disorders were operated on by anterior or posterior approach. These cervical disorders were myelopathy and radiculopathy with cervical spondylosis, disc herniation, fracture-dislocation, calcification of the posterior longitudinal ligament, angulation myelopathy after laminectomy and spinal arachnoiditis.
[Results]
In the cervical spondylotic myelopathy, as the duration of symptoms prior to surgery elapsed longer than 2 years, the results of operation were worse.
In disc herniation and fracture-dislocation which were operated by anterior approach, the results were better.
The cephalo-caudal extent of laminectomy was carried out from C2 or C3 to C6 or C7, and facetectomy was extented about 5mm laterally into the neural foramina.
The sensation of numbness or paresthesia remained relatively unimproved.
