Resumen (ES)

The acetabular fixation by impaction has advantages
on other systems of fixing in the cementless arthroplasties
of the hip. Permit a better contact between implant and
bone and it does not need destruction of the receiving bony
surface. The new designs for fixation by impaction are manufactured
in titanium alloys and possess a rugged surface
cover at the same time with hydroxiapatite-coated. Some
models as the arthroplasty Bihapro possess fins for primary
stability in your external curbing to avoid the initial rotary
mobilization. This system of fixation is showing good results in
the known experience and though the periods of follow-up
are yet short, the obtained bony integration is satisfactory.
We presented the results of 1107 Bihapro cups implanted with
a follow-up from one to seven years, that they have followed
a computed protocol. In only a case was presented lossening
of the component that specified review surgery.
