Cemented Stem Co-Cr

Design of Cemented Stem

Overview: The cemented stem is engineered for optimal performance in total hip arthroplasty, focusing on reducing wear, enhancing stability, and improving range of motion.

Neck Features

1. Neck Angle:
   • 135-Degree Angle: This angle is designed to support natural hip biomechanics, enhancing movement and stability.
   • Highly Polished Surface: The polished neck minimizes friction with the UHMWPE component, reducing grinding and wear over time.
2. Standard Offsets:
   • Compatibility: Designed with standard offsets to ensure easy integration with various acetabular components, accommodating a range of patient anatomies.
3. Reduced Proportionate Neck Geometry:
   • Enhanced Range of Motion: The slimmer neck geometry facilitates greater articulation, improving flexion and overall mobility.

Design Elements

1. Biplanar Taper Without Collar:
   • Force Conversion: This design converts longitudinal shear forces into lateral compression forces, enhancing the stability of the implant and reducing the risk of loosening.
2. Highly Polished Surface:
   • Reduced Shear Forces: The polished finish minimizes shear forces between the prosthesis and bone cement, promoting better long-term integration.
3. Smooth Prosthesis Edges:
   • Avoids Stress Concentration: Rounded edges prevent stress concentrations that could damage the bone cement interface, enhancing durability.
4. Collarless Design:
   • Improved Articulation: The collarless feature allows for better joint movement and reduces the risk of impingement, facilitating natural hip function.
5. Head Taper:
   • 12/14 Taper Configuration: This taper ensures compatibility with standard femoral heads, providing a secure attachment and optimal load distribution during movement.
