Description

Müller Antiluxante cup The cup is a antiluxante Müller hip system with long years of experience that guarantee correct operation in cases of total hip arthroplasties. The system made ​​of Polyethylene Ultra High Molecular Weight (UHMWPE), and a GUR 1020 composition, compression molding process offers high strength characteristics, minimizing wear conditions. Technical details Surgival Müller type cups are characterised for being hemispherical cups manufactured entirely from ultra-high-molecular-weight polyethylene (UHMWPE). The hemispherical design enables the maximum bone capital to be conserved, guaranteeing uniform load distribution to the bone thanks to a narrow contact with the acetabular bone of less than 0.5 mm. They are cemented cups, which means that on their convex external surface they have a special grooved design aimed at improving the cup's primary fastening. This primary fastening takes place on the cup's impact on the acetabular cavity, which is previously filled with bone cement. This impaction ensures the bone cement permeates the mechanised grooves in the cup and that, once the bone cement has set, they act as retainers to prevent the cup from rotating or loosening. The purpose of these grooves is also to increase the specific surface on contact with the acetabulum, providing greater peripheral contact and limiting the appearance of possible micro-movements that may cause prosthetic loosening. On the outside, all cups in the range have the same finishes in terms of grooves and channelling, depending on the number and placement of the cup's acetabular size or diameter.
