Frequently Asked Questions
What are the key features of the AVATAR NXT Stem?
The AVATAR NXT is a cemented hip stem featuring a highly polished, double-tapered design intended to create radial compressive loading. It uses a forged HNSS alloy, a collarless neck for intraoperative leg-length adjustment, reduced distal profile, a universal 12/14 neck taper, and an innovative hollow UHMWPE centralizer designed to allow distal stem engagement within the cement mantle.
Why is the AVATAR NXT Stem collarless?
The AVATAR NXT Stem has a collarless neck to allow intraoperative adjustment of leg length. This design provides the surgeon with greater flexibility when optimizing femoral component positioning and restoring hip biomechanics during cemented total hip arthroplasty.
What material is used in the AVATAR NXT Stem?
The AVATAR NXT Stem is manufactured from forged HNSS alloy, offering high fatigue resistance and biocompatibility. The material is used in conjunction with the stem's polished, double-tapered design to support its cemented fixation philosophy.
What is a cemented femoral stem?
A cemented femoral stem is a hip implant secured within the prepared femoral canal using bone cement, typically polymethylmethacrylate (PMMA). The cement creates a fixation interface between the stem and bone. In contrast, cementless stems rely on press-fit fixation followed by biological bone growth onto the implant.
Is a cemented hip replacement suitable for older adults?
Cemented femoral stems may be particularly suitable for some older adults, especially those with poor bone quality or increased fracture risk. The AAOS guideline states that cemented stems could be considered in older adults undergoing THA for symptomatic hip osteoarthritis and recommends cemented stems for arthroplasty following femoral neck fractures. Individual selection depends on bone quality and patient factors.
What are the common symptoms of severe hip arthritis?
Common symptoms include persistent hip or groin pain, stiffness, reduced range of motion, difficulty walking, and pain that may worsen with activity or after periods of rest. As arthritis progresses, pain may occur at night or during rest, and patients may develop a limp or difficulty performing everyday activities such as bending or climbing stairs.
