Frequently Asked Questions
What is the AVATAR NX Stem?
The AVATAR NX Stem is an uncemented femoral stem designed to restore hip joint mechanics while supporting bone conservation. It features a double-tapered design, metaphyseal flare, vertical and horizontal grooves for axial and rotational stability, optimized neck geometry, reduced distal profile, and a universal 12/14 neck taper. It is designed to provide fit and stability across different bone anatomies.
What is the benefit of the double-tapered stem design?
The double-tapered design of the AVATAR NX Stem is intended to avoid proximal stress shielding while supporting stable fixation. The stem also incorporates a metaphyseal flare for fixation and proximal load transfer, while vertical and horizontal grooves increase bone-contact area and contribute to axial and rotational stability.
What material is used in the AVATAR NX Stem?
The AVATAR NX Stem is manufactured from forged Ti-6Al-4V ELI (titanium alloy). According to the product information, this material offers high fatigue resistance and biocompatibility. Titanium alloys are widely used in uncemented hip stems because of their mechanical properties, biocompatibility, and suitability for biological fixation
What is the role of the femoral stem in total hip arthroplasty?
The femoral stem anchors the femoral component within the proximal femur and connects to the femoral head. It helps restore hip biomechanics and provides stability and load transfer between the implant and femur. In uncemented systems, appropriate initial stability supports subsequent bone ingrowth and biological fixation around the implant.
What are the advantages of modern titanium hip implants?
Titanium alloys offer a combination of biocompatibility, high strength-to-weight ratio, corrosion resistance, and a relatively low elastic modulus. These characteristics make them suitable for uncemented hip implants and can support bone ingrowth and biological fixation. The AVATAR NX Stem uses forged Ti-6Al-4V ELI and incorporates design features intended to enhance stability and load transfer.
