The exceptional feature of Lubinus Cup is the high cup rim, which projects beyond the spherical shape. This cup geometry reduces any luxation risk, which is further decreased by an additional snap-fit version. Another feature of the acetabular cup is its eccentric shape. This facilitates maximum material thickness in the main load-bearing zones (cranial)⁴.

In combination with SPII Model Lubinus Hip Stem, Lubinus Cup offers an outstanding, anatomically adapted cemented hip implant. Lubinus Cup is available in both standard UHMWPE and highly cross-linked polyethylene X-Linked.

The IP Cup as well as Lubinus Cup is designed with a high cup rim, which projects beyond the spherical shape. The IP Cup differs from the Lubinus Cup in integrated chamfer at the cup entrance. This gives the patient a wider range of motion due to the design where the neck of the prosthesis strikes the cup rim later.

The IP Cup is a cemented acetabular cup made of UHMWPE: both versions of IP Cup from standard UHMWPE and X-Linked UHMWPE are possible.

Same as other cemented acetabular cups, the design of FAL Cup with vertical and horizontal grooves in the surface creates a high degree of cement contact and allows air to escape when the implant is pressed into the cement bed⁴ with a uniformed cement mantle. In addition, the FAL Cup has a peripheral rim, unlike the IP Cup or the Lubinus Cup. This rim increases the cement compression, which increases cup stability in the cement matle⁷.

FC Cup has integrated high cup rim, which projects beyond the spherical shape. The FC Cup differs from the FAL Cup in integrated chamfer at the cup entrance. This gives the patient wider range of motion due to increased distance to a contact point between the cup rim and the implant neck. In addition, unlike the IP Cup and the Lubinus Cup, the FC Cup has a peripheral rim.

The Endo-Model Cup features an integral medioventral recess, which provides a wide range of motion and protects the femoral nerve together with psoas tendon. Psoas tendon or femoral nerve can be irritated by the cup rim in case of larger cup diameters.⁴ In addition, Endo-Model cup has a partial peripheral rim, unlike the IP Cup and the Lubinus Cup. This rim increases the cement compression resulting in a better cup stabilization in the cement mantle.⁷ 

Due to its anatomically adapted medio-ventral cut-out, Endo-Model Cup comes in two versions: right and left. Both versions have a circulating flange around the cup, except for the cut-out. 

LINK has decades of experience in the use of UHMWPE and this was particularly valuable in the design of the cemented acetabular cups. The high quality of the polyethylene demonstrably minimizes abrasion suffered by the components, thereby reduces the risk of osteolysis. Consequently, the incidence of component loosening is very low. In addition to the Standard UHMWPE, we also supply the system in acetabular cups made of X-Linked UHMWPE. This highly crosslinked polyethylene makes it possible to achieve even lower abrasion levels.^{2, 3}

In addition to the material properties, the external shape of the acetabular cups help to prevent loosening. Vertical and horizontal grooves in the surface create a high degree of cement contact and allow air to escape when the implant is pressed into the cement bed.⁴ Approximately 0.5 mm of play between prosthesis head and acetabular cup allows for “lubrication” by body fluids⁶. Furthermore, spacers on the rear surface of the acetabular cup permit a uniform cement coating. This surface design increases the stability of the cup in the acetabulum, thereby largely eliminating the risk of loosening.⁵ This design is used successfully in the FC, FAL, and IP as well as Lubinus Cup.
