[Experience with the implantation of porous coated hip endoprostheses and primary stability of implantation].

The use of porous coated cementless prosthesis, shows a worldwide spread in consequence of the advantages given by the "live" connection between the implant and the bone. Based on 40 implantations of prostheses of this type (Duraloc 1200 acetabulum, AML shaft) authors report on the technique of the implantation and the primary stability reached. In consequence of the formation, the variety of size and the properly usable instruments for implantation, the prostheses could be used for every kind of deformed, dysplastic hips and good primary stability was reached in every case operated.
