OTI’s ALFA Total Hip System was designed to compete with popular fully coated distal fixation systems. The ALFA stem incorporated the extensively coated stem with superior design features such as an 8degree anteverted neck, a smaller tapered and polished distal tip and a reduced neck taper.

The ALFA system includes revision line and cemented stems. The femoral stems and heads are manufactured from CoCrMo using a proprietary process. This material has a proven history of high fatigue strength, outstanding biocompatibility and superior resistance to corrosion.

FEATURES AND BENEFITS Fully porous coated stem with a tapered, polished bullet distal tip to reduce possible contact with the femur during flexion. Three dimensional porous coating allows 3D macro-interlock of bone into the depths of the porous coating down to the substrate. Coated with 3 layers of spherical beads with a mean pore size of 145 microns, which has proven to be the most effective for middle to distal 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. Porous coated collar provides excellent resistance to subsidence and rotational forces of the hip. Collar also helps to distribute stress to the proximal femur and maintain the proximal cortical support for the stem and creates an endosteal seal to inhibit the migration of particulate wear debris. Two proximal configurations allow good fit and fill in the proximal femur. Medial modified stem enhances proximal canal fill medially and laterally. 7 Stem diameters Proportional neck length system to allow for correct leg length and offset adjustments as the implants increase in size. Available with 35 mm and 38 mm neck lengths
