Tymochuk V. Differentiated approach to total hip arthroplasty in patients with rheumatoid arthritis

The thesis is devoted to the problem of substantiation and development of differential approach to the choice of a fixation type of the total hip joint endoprosthesis components with the aim of amelioration of patient treatment with rheumatoid arthritis with the hip joint lesion. On the basis of analysis of the treatment result of 85 patients with rheumatoid arthritis with the hip joint lesion whom 118 operations of the total hip joint endoprosthesis have been performed based on clinical and roentgenologic, immunologic and cultural, osteodensitometric and statistic examinations by the way of systematization and retrospective analysis of indices of osteogenic activity of bone marrow stem cells from various parts of the hip joint in patients with rheumatoid arthritis, the differential approach to the choice of the fixation way of endoprosthesis components has been developed. The thesis deals with the osteogenic activity of bone marrow stroma that forms the hip joint at the areas of future fixation of endoprosthesis components and density of bone tissue in patients with rheumatoid arthritis with the purpose of definition of a fixation type of the total hip joint endoprosthesis components at the preoperative period.
