Computer-aided design of a prosthetic socket for an above-knee amputee.
A computer-aided design process for fabricating the rectified cast for an above-knee prosthetic socket is described. The methodology for collecting the parameters required for the computer analysis is discussed. The input variables include the unloaded shape of the residual limb, the mechanical properties of the soft tissues that comprise the limb, and the surface loading that deforms the tissue. The technologies that have been developed to ascertain these parameters are presented, and the clinical experience of using the computer-generated shape is presented.
