Femoral Components

Bencox® ID Cemented Stem.

The Bencox femoral system from Corentec is a double-tapered, wedge stem, system designed to suit the anatomical structure in the marrow cavity. The section is rectangular-shaped, which helps to ensure strong initial press-fit fixation in the femoral marrow cavity. Designed with 12/14 specifications , the Corentec femoral system heads ensures compatibility with existing ball heads. Our femoral components offer a choice of stems, applying proven coating technology and patented neck design for a wide range of motion. In addition, they are compatible with either the Co-Cr head or our fourth generation delta ceramic head, which strengthens wear resistance and provides excellent biocompatibility.

Design Info


  • Polished Double Tapered Distal Geometry

    - Collarless type


    : “Taper slip principle” allows the subsidence of the stem.


    : Cement mantle longevity is related to the ability to convert shear forces and tension to the compression.


    : Proximally tapered and grooved stem geometry normalize proximal stress.


  • Optimal Design for Cement Pressurization


    : Enhances cement pressurization to help with bone cement interdigitation.


    : Vertical groove also loads the compression to the cement mantle.


  • Wide Range of Motion

    Enhanced Neck Shape


    : Patented trapezoidal neck design allows for a wide range of motion, and protects against impingement and dislocation.


  • Uniform Instrumentation


    : Cementless and cemented stem of the Bencox ID system utilize the same instrumentation.


    : This may maximize efficiencies in the operating room, while still providing intraoperative flexibility.


  • Self-centering Distal Centralizer

    Enhanced Neck Shape


    : Uniform cement thickness is constructed by four deformable wings of centralizer, which protects the stress concentration due to the thin cement mantle.


    : Allows the cemented stem to move distally within the cement applying the compression to the cement.
