Cementless Short Stem

Design of Cementless Short Stem

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

Neck Features

1. Neck Angle:
   • 135-Degree Angle: This angle supports natural hip biomechanics, improving movement and stability.
   • Highly Polished Surface: The polished finish reduces friction between the stem neck and UHMWPE component, minimizing wear.
2. Standard Offsets:
   • Compatibility: Standard offsets ensure integration with various acetabular components, accommodating different patient anatomies.
3. Reduced Proportionate Neck Geometry:
   • Increased Range of Motion: A streamlined neck design enhances articulation and flexibility, allowing for improved hip function.

Design Elements

1. Distal Grooves:
   • Enhanced Rotational Stability: The presence of distal grooves improves rotational stability during dynamic movements, reducing the risk of implant loosening.
2. Titanium Coating:
   • Partial and Fully Coated Options: Titanium coatings enhance osteointegration, promoting bone growth around the implant and improving long-term stability.
3. Distal Bullet Tip:
   • Avoids Stress Shielding: The bullet-shaped tip is designed to minimize stress shielding, allowing for better load transfer to surrounding bone.
4. Collarless Design:
   • Improved Motion: The collarless feature enhances articulation and decreases the risk of impingement, promoting better joint function.
5. Head Taper:
   • 12/14 Taper Configuration: This design ensures compatibility with standard femoral heads, providing a secure attachment and optimal load distribution.
