[Periprosthetic osteolysis following the total hip arthroplasty]

The periprosthetic osteolysis is one of the complications of artificial joint replacement. The function and the stability of the hip joint will be severely affected once the periprosthetic osteolysis occurred postoperatively,so it's necessary to fully recognize the mechanism of the osteolysis. There is no globally accepted diagnostic standard of this disease, and then, the grading of the postoperative hip joint function is indispensable. The using of diphosphonate to prevent the osteolysis has positive significance, but it is not broadly used in clinical. Taking the periprosthetic osteolysis of hip arthroplasty as the central, this article shows a briefly overview of this subject.
