Paper Abstract

A system is described that delivers three-dimensional shape to plan corrective surgery and directly manufacture prosthetic implants. Geometry of implants are manufactured to precise dimensions using CT image data and an algorithm to generate instructions for numerically controlled milling machines. This work extends previous work in CT image segmentation algorithms to wed structure contour data to machinery used for making special implants. The types of implants currently available come in only a few sizes. A combination of changes to both the standard implant and, unfortunately to the femur itself are required to have a firm, stable reconstruction. The system out-lined here minimizes the removal of patient skeletal mass by manufacturing implants customized for each patient. The system is interconnected via digital transmission lines and will become entirely automated. Example implants are shown and new application areas are presented.
