title: [Cementless Endoprosthesis of the Hip Joint ABG: Description of the Implant, Operation Technique.].
abstract: A non-cemented endoprosthesis of the hip joint ABG is producet by Howmedica Co. from a titanium alloy. The socket is hemispherical, primarily anchored according to the press fit principle. The external surface of the annulus is covered by a layer of hydroxyapatite. The shape of the shank is anatomical, it respects the anterior curvature of the femur and the anteversion of the neck of the femur. Its primary stability is ensured by the shape of the shank, the secondary stability is achieved in the process of osteoinduction in the metaphyseal part covered by hydroxyapatite. Between 1992 and 1994 18 hip joints were operated. No peroperative nor postoperative complications were observed, the short-term results are very good. With regard to the short follow-up time, long-term clinical results will be the subject of subsequent papers. Key words: non-cemented endoprosthesis of the hip joint, press fit principle, hydroxyapatite, osteoinduction.
