[Design, production and clinical application of custom total hip prosthesis]

The key to the research of the hip prosthesis is to prolong the effective using time of the hip prosthesis, but bone loss and aseptic loosening are the influential factors in this aspect. Since each person has his own characteristic, it is difficult for the standard hip prosthesis to fit with the patient's femoral canal, so the stability can not the ensured. Moreover, some patients have congenital abnormality or a serious defect in bone or arthrosis, which makes an obvious deviation from the normal, therefore they can not use the standard hip prosthesis. CAD/CAM is useful for to individual three-dimensional femoral reconstruction, which can improve the stability of the prosthesis and effectively prevent the loosening of prosthesis. This article introduces the advantage, design, production and the problems of custom CAD/CAM hip prosthesis.
