Periprosthetic Osteolysis of the Cementless Femoral Stems

Abstract
|
|
|
Periprosthetic osteolysis may be the most common cause of late failure of total hip arthroplasty perfomed without cement and its incidence is increasing with time. Several studies demonstrated high rate of femoral osteolysis of the cementless total hip arthroplasty. However, there are a few reports about the higher rate of femoral osteolysis in bipolar hemiarthroplasty inserted without cement than its incidence in cementless total hip arthroplasty.
The purpose of this study was to find out the incidence and the characters of the periprosthetic osteolysis and to analyse its relation with the possible factors; age, sex, size of the acetabular cup or the femoral stem, stability of the femoral stem, and clinical score with osteolysis in bipolar hemiarthroplasty and total hip arthroplasty inserted with-out cement.
.The authors analysed twenty-one cases in eighteen patients of bipolar hemiarthroplasty and twenty-eight cases in twenty-five patients of total hip arthroplasty inserted with non-circumferential porous coated femoral stem of Harris-Galante type and femoral head of 28 millimeter diameter from Jan. 1985 to Dec. 1991. All of the patients were followed up for at least four years. The average follow up period was 59.6 months (48 to 96 months) in bipolar hemiarthroplasty group and 60.8 months(48 to 96 month) in total hip arthroplasty group.
