OTI’s LSF Total Hip System were designed to incorporate state of the art knowledge in biological fixation interfaces as well as bone remodeling. The result is a stem which will achieve long-term interface fixation as well as bone maintenance and constructive bone remodeling. The LSF was designed based upon years of laboratory research on porous coated implants including material selection fabrication, pore structure and location, rate and type of tissue ingrowth and interface attachment.

FEATURES AND BENEFITS 45% porous coated stem with a blasted distal portion and polished tip. Three dimensional porous coating allows 3D macro-interlock of bone into the depths of the porous coating down to the substrate. Coated with 2 layers of spherical beads with the optimum range of 250-350 micron pore size for maximum stability fixation and stress distribution, which has proven to be the most effective for proximal femoral fixation. Available with or without Hydroxyapatite coating. Reduced neck taper, reduces bulk of the stem and thereby increasing the range of motion of the hip. 7 Stem diameters Available with 35 mm and 38 mm neck lengths 8 degrees of anteversion has been incorporated to add stability to the joint. Neck designed to withstand necessary physiological loading and to allow for the greatest range of motion.
