## Abstract We have developed a prosthetic replacement for the intervertebral disc. Although current management of a patient with degenerative disc disease is usually effective, certain inadequacies in permanent pain relief do exist. Most of the persistent symptoms seem to occur because of vertebra

โฆ Synopsis
In this study measurements were obtained from 359 vertebrae and 215 intervertebral discs in an attempt to classify discs by their size. At the cervical and thoracic levels, this attempt was unproductive because of extensive variations. In the lumbar spine, discs were allocated to six size-matched groups and to two height-matched groups. The breadth of marginal rims were also measured with a view to provide surgeons operating on the spine with precise data on disc morphology to facilitate disc replacement.
