Component shape, surface finish, and presence of holes for adjuvant screw fixation should all affect initial stability and hence long-term fixation of total hip acetabular components. We conducted a study to determine stability against edge loading and torsion in commercial implants that differed in these design variables. Components were seated into synthetic cancellous bone blocks, and loads and insertion energies necessary to seat the components were measured. Components were then edge… CONTINUE READING
