Optimization of total hip arthroplasty for dysplastic coxarthrosis

Degenerative-dystrophic hip damages are among urgent problems, for which endoprosthesis replacement is considered a relevant solution for 100 to 300 cases per 100,000 population per year. Aseptic instability of the endoprosthesis components dominates the environment of unsatisfactory outcomes in the long term. To prevent aseptic instability of the hip endoprosthesis components in the hip pathology, the authors propose a method of "incision" on the tendon part m. iliopsoas and use of the intraoperative method to determine the centre of the endoprosthesis head rotation. This work analyses the surgical treatment method of 103 patients operated on in the traditional way and 91 patients who underwent surgical incision of the m.iliopsoas tendon using the intraoperative method to determine the centre of the endoprosthesis head rotation.
