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.
共评估了167例陶瓷-陶瓷骨水泥型关节成形术，平均随访62.5个月。股骨组件未出现松动迹象。5例患者观察到髋臼松动。对两组（第一组年龄在70岁以下，第二组年龄在70岁及以上）进行的统计研究未发现髋臼组件失败与患者年龄之间存在任何关系。对5例松动病例基于双能X线吸收法（DXA）系统进行的骨密度评估显示，其与随访参数相关而降低。根据我们的经验，对于骨营养良好、骨密度显著降低的患者，植入陶瓷-陶瓷骨水泥型假体是一种可靠的选择；最好使用聚乙烯-陶瓷植入物。
