Preliminary results in 167 bioceramic cemented arthroplasties with five-year follow-up in patients aged 60 years or over.
A total of 167 ceramic-ceramic cemented arthroplasties with a mean follow-up of 62.5 months were evaluated. There were no signs of loosening in the femoral components. Loosening of the acetabulum was observed in 5 patients. A statistical study conducted on the two groups (the first aged under 70 years, the second aged 70 or over) did not reveal any relationship between failure of the acetabular component and the age of the patient. An evaluation of bone density based on the DXA system in 5 cases of loosening revealed its diminution in relation to follow-up parameters. Based on our experience, implantation of the ceramic-ceramic cemented prosthesis is a reliable choice in patients with good bone trophism, in those where there is a significant reduction in bone density; it is best to use polyethylene-ceramic implants.
