Аллопластика тазобедренного сустава эндопротезами двойной мобильности в нестандартных ситуациях

The article presents the results of arthroplasty of 29 patients with III stage coxarthrosis. The peculiarities of the surgical interventions were that in the postoperative period due to concomitant orthopedic pathology (ankylosis of the opposite hip, two-way coxarthrosis with flexion-leading contractions with shortening greater than 4 cm; dysplasia of the upper extremities), patients are forced to use the operated limb. as basic. The reason is the inability to implement the recommendations for sitting at a right angle, loading an operated limb by weight, to use crutches and to exercise the muscles surrounding the hip joint. When classical endoprosthesis with heads having D = 28, 32, 36 mm is employed, because of the instability in the postoperative period the high risk of dislocation is saved. At the same time, the use of a Medacta Versafitcup Double Mobility prosthesis allows achieving the stability of the operated joint and ensuring its long life.
