Cemented Stem SS

Design of Straight Stem

Overview: The straight stem is designed for total hip arthroplasty, focusing on enhancing stability, reducing wear, and optimizing range of motion.

Neck Features

1. Neck Angle:
   • 135-Degree Angle: This angle is optimized for natural hip biomechanics, facilitating improved movement and stability.
   • Highly Polished Surface: The polished neck minimizes friction with the UHMWPE component, reducing wear and enhancing longevity.
2. Standard Offsets:
   • Compatibility: Designed with standard offsets to ensure seamless integration with various acetabular components, accommodating diverse patient anatomies.
3. Reduced Proportionate Neck Geometry:
   • Increased Range of Motion: The streamlined neck design enhances articulation and flexibility, allowing for improved hip function.

Design Elements

1. Collarless and Collared Options:
   • Versatility: Available in both collarless and collared designs to meet different surgical and anatomical needs.
2. Highly Polished Surface:
   • Reduced Shear Forces: The polished finish decreases shear forces between the prosthesis and bone cement, promoting long-term stability.
3. Smooth Prosthesis Edges:
   • Avoids Stress Concentration: Rounded edges help prevent stress concentrations, minimizing the risk of damage to the bone cement interface.
4. Head Taper:
   • 12/14 Taper Configuration: This design ensures compatibility with standard femoral heads, facilitating secure attachment and optimal load distribution during movement.
