[Initial Experience with Non-cemented Endoprosthesis of the Hip Joint with a Porous Surface.].
The author describes his experience with implantations of non-cemented endoprostheses of the hip joint with a Porocoat lining in a group of 85 patients with an average age of 56 years. He describes the surgical technique and the most frequent mistakes. He evaluates the group with regard to the relatively short follow-up period of 3 - 48 months (mean 18 months). In all instances the patient's pain was mitigated and the scope of movement increased. On X-ray no signs of loosening were found although in 12 instances the femoral component was not settled quite press fit (so far without clinical manifestations). Analysis of complications provides important information on the correct surgical technique and on the use of a press fit implant in conjunction with fixation by screws. In the discussion the author gives an account of data from the literature on long-term results of non-cemented endoprostheses with a porous surface and discusses results obtained with other non-cemented endoprostheses. Key words: non-cemented endoprostheses of the hip joint, porous surface of endoprosthesis, complications.
