Cemented femoral stem BC1

1. The edges of the prosthesis are smooth to avoid stress concentration and cut bone cement; 2. The double-tapered collarless design transforms the longitudinal shear force into lateral compressive stress; 3. Highly polished surface reduces the shear force of the contact surface between the prosthesis and the bone cement; 4. Allow the stem to sink slightly and fix it twice; Used with the third-generation bone cement technology, longer life time and better clinical effects.
