To the Editor.—
I find discography a valuable adjunct in treating patients with a disk problem in the neck and low back. My position is a matter of record and, although quoting me in his "Conclusions," Holt obviously has not paid attention to the content of the article, other than its being based on 247 operations performed on 221 patients. The connection between Colorado's slightly less than 100 years of statehood and the number of ruptured cervical disks diagnosed and treated escapes me. It would seem to be fairly clear to any thinking person that the incidence of cervical disks, even in Colorado, probably has increased since the advent of the automobile, with the ever-growing density of traffic and the increasing number of traffic accidents resulting therefrom, as compared with the founding years when an occasional citizen may have ruptured a disk in falling off a horse.
