title: The myelography needle: a new cannula for aspiration.
abstract: Painless recovery of radiopaque substances after positive contrast myelography is often difficult, especially if the initial spinal tap is not made precisely in the midline. The author has designed a cannula for aspiration which has performed favorably in clinical tests and which will soon be available commercially.
