Cemented or non-cemented femoral stem LCU®

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 The stability of the implant is additionally enhanced by the characteristic metaphyseal V-shape, while the rectangular cross-section neutralizes torsional forces. Meta-diaphyseal support and fixation provided by a large medial curvature with a 100 mm radius for anatomical adaptation. Cementless Version 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. 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. 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. Cemented Version The stem is made from our EndoDur-S (CoCrMo alloy). It can be operated with the same broaches as the cementless version allowing for intraoperatively flexibility. The stem is highly polished to reduce the risk of cement abrasion.
