DESIGN, NUMERICAL ANALYSIS AND MANUFACTURING OF ARTIFICIAL HIP JOINT IMPLANTS (original) (raw)

Hip arthroplasty has proven to be a reliable and suitable surgical procedure to re-turn patients back to function. Patient selection, surgical procedures and of the condition and the use of an appropriate implant plays a tremendous role for the success of the surgery, without the need of a revision in the near time. [1] The design and the final inspection of these implants have a very important place in the whole procedure of their manufacturing, and of course in their tendency to failure. [2] For this rea-son strict international standards were instituted to protect and make reliable the design and the machining of them. In both these procedures the dimensional and geometrical accuracy are very important and the limits of the acceptance of any inaccuracy are very narrow. In this paper it will be presented the whole procedure of producing such parts, using specific CAD/ CAE / CAM software for that, and the inspection of the implants, femoral heads which were made, with the use of AFM for its surface roughness accuracy.
