The authors have made an analysis of unsatisfactory remote results in 83 (21.5%) out of 387 patients operated for endoprosthezing of the hip joint which resulted from shaking loose the endoprostheses in the bone tissue. A conclusion is made that the following factors may be considered as contraindications to endoprosthesis of the hip joints: coxarthrosis against the background of arthroso-arthritis, neglected stages of protrusive coxarthrites, deforming osteoarthrosis due to the use of corticosteroids, pronounced senile osteoporosis.
