Ivanov O. Hip joint replacement at dysplastic coxarthrosis

Object of research. Patients with dysplastic coxarthrosis. The purpose. To improve results of total hip joint replacement at patients with dysplastic coxarthrosis by development of optimum variants of prostheses designs on the basis of research radio-anthopometrical and clinical characteristics of hip joint at this category of patients. Methods of research: clinical, radiological, radio-anthopometrical, electrophysiological, densytometrical, biomechanical and statistical. Scientific novelty. On the basis of executed X-ray researches proximal department of a femur at dysplastic coxarthrosis statistically authentic objective attribute dysplasia proximal department of a fe-mur is revealed X-ray-anatomical; the design is advanced and standard sizes of a femoral component of prosthesis ORTEN and a technique of its implantation are proved; indications for the differentiated choice of a femoral com-ponent of prosthesis ORTEN are developed at planning and carrying out hip joint replacement at patients with dys-plastic coxarthrosis. On the basis of research of a condition of mineral density of a bone fabric proximal department of a femur in dynamics after replacement terms of loading on finiteness, and also optimum terms between operations on the first and second joints at patients with bilaterial dys-plastic coxarthrosis are determined. The technique of post-operative rehabilitation of this category of patients is ad-vanced.Positive outcomes are received in 94,5 % of supervi-sion (excellent - 55 %, good - 30,2 %, and satisfactory - 9,3 %) that testifies for the benefit of high efficiency of medical rehabilitation of this contingent of patients at ap-plication of prostheses ORTEN.Results of research are introduced into clinical practice at the clinic of joints replacement of the Dnepropetrovsk regional clinical hospital named after I.I.Mechnikov, or-thopedic-traumatological department of the Kharkov re-gional hospital, clinic of a pathology of large joints of the Kharkov scientific research institute of a pathologyof a backbone and joints, department of orthopedy and trauma-tology of the Cherkassk regional hospital, clinics of trau-matology and orthopedics of Vinnitsa national medical university named after N.I.Pirogov and the Zaporozhye state medical university, department of the operative ar-thrology of the Sevastopol city hospital №9.
