Objective To research and develop the preoperative super-selection system for selecting proper prosthesis for patients. Methods This system integrates the latest achievements about hip prosthesis selection and analyse the characteristics of the hip prosthesis’ figure and size based on hip orthotopic radiograph to set up the super-selection regulations. This Hip Prosthesis Preoperative Super-selection System developed with both MATLAB and VB could be also used to evaluate the select results from geometry and stress aspects. Results To develop the preoperative super- selection system, the guides and the methods for this super-selection were established and evaluated. Conclusion The super-selection system can make the proper choice of hip prosthesis for patients according to femur characters of patient’s pelvis X-ray films.
