Double Medical PBG Cementless Hip Stem System

Double Medical Proximal Bone Growth (PBG) Cementless Stem System: 3° biplanar taper design matches natural femoral canal. Load transfer takes place superior to the metaphyseal-diaphyseal junction and avoid stress shilding in the distal part. Three point contact and fixation achieve immediate rotational stability. Radial step grooves aligned secondary compressive trabeculae group. Convert hoop stresses to compressive loads and avoid bone fracture intra-operation. Increase contact are a with host bone for better bone ingrowth. Proximal Vaccuum Plasma Coating: 200um thickness, 200um pore size, and 30%porosity, ensure bone in-growth. Grit-blasted distal bullet tip avoids cortical impingement and reduces thigh pain.
