Abstract

Implantation of total hip endoprosthesis may be accompanied by a number of mechanical complications. Radiographics images of 250 total hip endoprostheses (SAS, AHS, Muller) show the positions of acetabular and femoral components of implanted endoprostheses. Measurements have shown that the decline of implanted acetabulum ranged from 41 to 50 degrees in 44.4% of patients, i. e. in 75.6% of patients the angle of acetabular decline ranged from 36 to 55 degrees. The position of endoprosthesic shaft was neutral in 84.4% of patients; 7.2% of patients had varus position of the stem of shaft, whereas 8.4% of them had valgus shaft position. Improvement in operative technique is undoubtedly the major factor contributing to a decreased number of mechanical complications in total hip joint endoprosthetic implantation.
