Early and Mid-Term Results of Primary Hip Arthroplasty Using Il’za Endoprosthesis

Abstract

The problems of hip arthroplasty under conditions of wide introduction of that surgical intervention into clinical practice and the perspectives of cementless wedge-shaped femoral stems use are discussed on the example of high-technology home endoprosthesis “Il’za” are discussed. Technical characteristics of the implant, peculiarities of surgical procedure with its application, early and mid-term clinical and roentgenologic results of 581 operations are considered. Stable deterioration of hip function has been noted in 1, 2 and 3 years after operation - from 37.6 points by Harris hip score to 89.3, 92.2, and 89.1 points, respectively. Survival of the femoral component in 6 years after arthroplasty made up 98.6%, general survival - 96.2%. Universality of this femoral component that enables to achieve its stable primary and secondary fixation in the absolute majority of patients is proved. The achieved data allow to talk of the reliability of wedge-shaped femoral hip stems and significant prospective for their use in wide clinical practice.
