Unified Instrumentation

• Cementless and cemented stem of ID system use same instrumentation.

• This instrumentation maximizes efficiency in the operating room,

while still providing intraoperative flexibility.

Compatible Tapered 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

Normalized Proximal Stress

• Proximally tapered stem geometry converts the shear forces to compressive load.

• This helps the stem to resist subsidence and medial migration.

Extensive Stress Distribution

• Low elastic modulus of Ti alloy and the double tapered stem reduce stiffness

which avoids distal load transfer and prevents proximal stress shielding.

Enhanced Rotational Stability

• Rectangular cross-section

• Longitudinal grooves

- Longitudinal grooves are designed to resist rotational motion

Polished Double Tapered distal geometry-Collarless type
Generates the radial compressive load 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.

Enhanced Neck Shape

• Patented trapezoidal neck design allows wide angulation

and protects impingement & dislocation.

• Same neck design with Bencox Stem is applied.

Compatible Tapered 12/14 Trunnion

• Adaptation of Bencox Forte & Delta, and Metal heads

• Provides 3 optional offset (Short, Medium, Long).

• Extra long offset provided for Metal heads
