To the Editor.—  I would like to comment on the section regarding developments in prosthetics in the article entitled "Physical Medicine and Rehabilitation" by Dr Glass1 in the Oct 17, 1986, issue. Although I take issue with only two sentences and the tense of the verbs used in the article, these details are of critical importance."In the past few years a semiautomated system of prosthetic manufacture has been developed [italics added]," writes the author. To be precise, these systems, the so-called CAD-CAM (computer-aided-design; computer-aided-manufacture) systems, to which Dr Glass alludes deal only with the prosthetic socket and are such that even the most optimistic proponents do not claim clinical readiness at present. Critics of these systems would say that without a significant breakthrough in current technology they may never be of any clinical value.It is well understood that correct fitting and fabrication of prosthetic sockets requires data
