Reflections on CAD/CAM in Prosthetics and Orthotics
John W. Michael, M.Ed., C.P.O.
The computerization of manufacturing has been termed the "Third Industrial Revolution." The author discusses how this might affect the design, fitting, and manufacturing of orthoses and prostheses.

The CAPOD System-A Scandinavian CAD/CAM System for Prosthetic Sockets
Kurt Oberg, Ph.D.
Jonathan Kofman, M.Sc.A., P.Eng.
Arne Karisson
Billy Lindstrom
Goran Sigblad, C.P.O.
This paper presents a low-cost CAD/ CAM system to design and manufacture below-knee prosthetic socket molds. The preliminary clinical evaluations of 21 below-knee amputees are reviewed.

Rectification Maps: A New Method for Describing Residual Limb and Socket Shapes
John A. Sidles, Ph.D.
David A. Boone, B.S., C.P.
Jon S. Harlan, B.S.M.E.
Ernest M. Burgess, M.D.
A new technique is presented for quantitatively describing the difference between residual limb shapes and socket shapes from a completely general and three-dimensional approach.

Computer Designed Prosthetic Socket from Analysis of Computed Tomography Data
Virgil W. Faulkner, C.P.O.
Nicolas E. Walsh, M.D.
With the computer aided ability to reconstruct three-dimensional images of a residual limb, the authors describe how the shape can be altered to make it biomechanically correct for prosthetic socket manufacture. The image data is then interfaced ...

A Computerized System to Manufacture Prostheses for Amputees in Developing Countries
Nicolas E. Walsh, M.D.
Jack L. Lancaster, Ph.D.
Virgil W. Faulkner, C.P.O.
William E. Rogers, M.S.
With the aid of CAD/CAM, the authors present a prosthesis which can be fabricated at a central site and then shipped to remote sites in underdeveloped countries. The socket is designed so that it can be fitted and modified by local technicians.

Computer Aided Design and Computer Aided Manufacturing of Foot Orthoses
Timothy B. Staats, M.A., C.P.
Michael P. Kriechbaum, B.A.
The application of CAD/CAM to foot orthotics increases the speed of production, increases the accuracy of the fabricated device, and eliminates the problem of storing hundreds and thousands of foot casts.

Automated Fabrication of Mobility Aids: Clinical Demonstration of the UCL Computer Aided Socket Design System
David A. Boone, B.S.P.O., C.P.
Ernest M. Burgess, M.D.
Generation of the positive plaster model of a PTB socket was accomplished using a computer, socket design software, and computer numerically controlled milling machine.
