Iso-elastic Acetabular component allowing for the bending of acetabular horns while walking. If necessary, the press-fit concept may be obtained by the impaction of a larger metal ring. Two rows of four spikes ensure a greater stability. Possibility of adapting a neutral insert or an insert with semi retentive rim. Hydroxyapatite coating to optimize osteointegration. Additional fixation by means of 3 self-tapping screws.
