revision acetabular prosthesis / cementless
Hemispherical cementless acetabular cup manufactured in Titanium alloy (Ti6Al4V) with double coating (PoroTi+HA), the DELTA-FINS cup is designed to fit acetabular sockets which may feature surgically adequate morphologies but require special care, such in case of dysplasia and certain early revision cases.
Equipped with equatorial vertical fins that penetrate into the bone tissue, enhancing torsional stability and achieving optimal primary mechanical fixation, the Delta PF model is about 1.2 mm press-fit with respect to the acetabular reamer. This mechanical interference allows for an optimal 360° press-fit effect.
Stronger fixation can be achieved by additional screw fixation by means of the 3 cranial holes with removable plugs available on the dome of the cup.
