The broken ceramic fragments and the ceramic head were sent to a research laboratory and were further analyzed. Alumina ceramic on ceramic bearings have very low wear rates in standard hip simulators. Profilometry results show that stripe wear regions have a sub stantially higher surface roughness than the as manufactured ceramic fig. Stripe wear has been reported in many ceramic on ceramic hip replacement retrievals and microseparation separation of the femoral head from the acetabular cup has been proposed as one suggested.
