•Cementless and cemented stem of ID system use same instrumentation.
•This instrumentation maximizes efficiency in the operating room, while still providing intraoperative flexibility.
Polished Double Tapered distal geometry
•Generates the radial compressive bad in distal body.
•'Taper slip principle" allows the subsidence of the stem.
-Cement mantle longevity is related to the ability to convert the shear and tension to the compression.
-Cement is 3 times stronger in compression than in shear or tension.
Normalized Proximal Stress
• Proximally tapered & grooved stem geometry converts the shear forces to compressive load.
Self-Centering Distal Centralizer
•Unifom 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.
EnhanrpH Nprk Shapp
•Patented trapezoidal neck design allows wide angulation and protects impingement & dislocation.
•Same neck design with Bencox Stem is applied.
Compatihlp Tapprpri 12/14 Trunnion
•Adoptation of Bencox Forte & Delta, and Metal heads
•Provides 3 optional offset(Short, Medium, Long).
•Extra long offset provided for Metal heads
After the exposure of the hip joint via the surgical
approach, femoral-neck resection can be carried
out following the gentle dislocation of the femoral
head. If dislocation is difficult, the femoral head
can be removed using a cork screw after neck
