Total hip replacement: improving cement fixation of the acetabular component

The primary aim of this study was to propose fixation techniques that would improve the cement fixation of the acetabular cup. This was done by (1) studying current practice, (2) creating FE models of the reconstructed acetabulum to predict improved fixation techniques, (3) validating the FE models by laboratory investigations and (4) proposing designs of jigs and drill bit that would assist orthopaedic surgeons use the recommended techniques.
