The objective of this study was to analyze the results of a cemented polyethylene model that captures the hip prosthetic head. In a retrospective study we reviewed 36 cemented constrained acetabular liners implanted in patients older than 75 years (mean 83, SD : 4.4), of which 30 patients were aged 80-90 years and 26 were women. The average period of follow-up of our patients was 25.4 months (12-39 months, SD : 7.3). In 26 patients this model was implanted due to recurrent dislocation or instability, in 8 other cases this model was implanted during revision surgery for periprosthetic fractures, aseptic loosening of the -acetabular component, wear of the polyethylene or replacement of the implant because of infection. There was a single case of recurrent dislocation (2.8%). Cemented acetabular constrained liners are a good option in revision surgery in senile patients in which the femoral stem is firmly fixed to the bone.
