title: Long-term results of cemented and screwed acetabular components.
abstract: The authors report their experience in the use of various types of acetabular components (cemented and screwed) in 253 hip prostheses with "Biodirect" femoral component and ceramic femoral head. A long-term follow-up of 148 hip prostheses (58.5% of the total) was carried out, 36 Müller type polyethylene and 61 Biolox ceramic acetabular components, and 51 screwed sockets of various models were used. From a clinical and radiographical standpoint, the ceramic acetabular component proved the most valid in the short and medium term, confirming the favourable biomechanical conditions which derive from ceramic/ceramic coupling.
