Cementless Long Stem

Design of Cementless Long Stem

Overview: The cementless long stem is designed for total hip arthroplasty, focusing on optimizing stability, promoting osseointegration, and enhancing range of motion.

Neck Features

1. Neck Angle:
   • 135-Degree Angle: This angle is tailored to support natural hip biomechanics, facilitating improved movement and stability.
   • Highly Polished Surface: The polished finish reduces friction with the UHMWPE component, minimizing wear and enhancing longevity.
2. Standard Offsets:
   • Compatibility: Incorporates standard offsets to ensure seamless integration with a variety of 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. Long Stem with Anterior Bowing:
   • 250 mm Length: The elongated stem features anterior bowing, designed to accommodate the natural anatomy of the femoral canal, enhancing fit and stability.
2. Full Titanium Coating:
   • Complete Osteointegration: The full titanium coating promotes robust osseointegration, encouraging bone growth around the implant for long-term stability.
3. Collarless Design:
   • Improved Articulation: The collarless feature allows for better joint movement and reduces the risk of impingement, promoting optimal joint function.
4. Head Taper:
   • 12/14 Taper Configuration: This design ensures compatibility with standard femoral heads, facilitating secure attachment and optimal load distribution during movement.
