Cementless femoral stem Bencox

• Femoral Component is a typical double-tapered wedge stem, designed to suit the anatomical structure in the marrow cavity. • The section is rectangular-shaped, allowing a strong initial press-fit fixation in the femoral marrow cavity. There are 15 sizes covering a developmental dislocation of a hip joint to a large marrow cavity. MAO (Micro Arc Oxidation) • To maximize bone ongrowth, the surface of the Femoral Stem is treated with micro arc oxidation, maintaining average 5.5㎛ of surface roughness. • Micro arc oxidation has 1-5㎛ diameter of numerous porosity structure, maximizing the contacting area with the surrounding bone and assisting in adhering the osteoblast. Also, MAO contains calcium and phosphate, the principal components of bones, on its surface which provides an excellent environment for bone ongrowth. Grit-Blasting Surface • The Bencox Stem is manufactured from titanium alloy (Ti6Al4V ELI), according to ASTM F136 / ISO 5832-3 and has a proven grit blasted surface finish (4-6㎛) with about two decades of clinical experience. Wide Range of Motion • Adoptation of Bencox Forte & Delta, and Metal heads. • Provides 3 optional offset(Short, Medium, Long). • Extra long offset provided for Metal heads. Normalized Proximal Stress • The innovative design on the ‘Neck’ of the Femoral Component (Patent # : 7311735, USA / ZL 2005 1 0081090.4, China / 10-0566584, Korea) minimizes possible impingement when flexing and extending a joint; using a 32mm or 36mm head maximizes the range of motion.
