  • Cemented implant for rapid postoperative mobilization1
     
  • Uniform cement coating by means of integral spacers
     
  • Deep cup with snap-fit effect counteracts the tendency to luxation
     
  • Eccentric geometry for maximum material thickness in the main load-bearing zones4
     
  • High UHMWPE quality means low abrasion2, 3, 7, 8

    Another feature of the cemented Lubinus Polyethylene Acetabular Cups is the high cup rim, which projects beyond the spherical shape. This cup geometry reduces any luxation risk, which is reduced even further 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.4 In combination with the LINK Lubinus SPII Femoral Stem, this system offers an outstanding, anatomically adapted cemented hip implant.

    In addition to the material properties, the external shape of the acetabular cups helps to prevent loosening. Radial notches on 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 fluids.9 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 Lubinus® Acetabular Cup and in the FAL and IP Polyethylene Acetabular Cups.
     

    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, and 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, 7, 8
     

    The LINK® Lubinus® Polyethylene Acetabular Cup is a cemented acetabular cup made of UHMWPE. The direct stability of the cup in the cement coating permits rapid postoperative mobilization of the patient. This, in turn, means shorter recovery times and shorter hospitalization for the patient.1
