The LCU Hip System offers a cemented and a cementless hip stem. The cementless version is available with a HX coating or a PoroLink (microporous) surface. All versions follow the concept of a straight stem with tapered lateral shoulder. The profile is straight with a rectangular cross-section.
For all different stem types of the LCU Hip System the same set of instruments is used, which allows for intraoperative flexibility.
Two offset types allow for adaption to the patient’s anatomy 2:
The stability of the implant is additionally enhanced by the characteristic metaphyseal V-shape, while the rectangular cross-section neutralizes torsional forces.5, 6, 8
The flat, tapered prosthesis neck allows a large range of motion between prosthesis stem and acetabular cup.2
The 12/14 mm taper is designed for the use of modular LINK prosthesis heads made of ceramic or metal with various lengths and diameters.
Furthermore, the highly polished neck region reduces abrasion in the event of unintentional contact with the acetabular cup.9
The stem is made from Tilastan-S (Ti6Al4V).
The micro-roughness of the metal surface is created by corundum-blasting, which produces an even and uniform surface structure with pore sizes and roughness values for osseointegration.2, 3
The HX coating with a thickness of 20 +/- 10 µm is applied by LEP (LINK Electrochemical Process) to the entire length of the prosthesis, and promotes bone ongrowth.4
The horizontal ribs in the proximal section of the stem serve to counteract subsidence of the stem and to promote primary stability. The distal region has vertical ribs to counteract the rotational forces.7
