High-Purity Titanium Constructs for Total Hip Arthroplasty (THA)

Le CytroFIX® Hip Replacement System by Cytronics (an INVAMED orthopedic division) is meticulously engineered for total hip arthroplasty procedures addressing osteoarthritis, rheumatoid arthritis, avascular necrosis, and complex revision scenarios. By combining high-purity titanium femoral stems, advanced acetabular shells, and precision-engineered bearing surfaces, this system aims to restore natural hip function, reduce pain, and enhance patient mobility over the long term.

Anatomically Contoured Femoral Stem
  • Designed with progressive geometry that replicates proximal femoral anatomy, accommodating varying canal shapes and sizes.
  • High-purity titanium alloy (e.g., Ti-6Al-4V ELI) ensures optimal strength, biocompatibility, and osteointegration potential.
  • Low-profile titanium shell featuring a porous or hydroxyapatite (HA)-coated surface for robust biological fixation in cementless (press-fit) applications.
  • Multiple dome hole configurations allow the use of acetabular screws for additional initial fixation if needed.
  • Femoral Heads: Available in cobalt-chrome, ceramic, or titanium-alloy options (often with specialized coatings) in multiple diameters and neck offsets.
  • Bearing Liners: UHMWPE (ultra-high molecular weight polyethylene) or cross-linked polyethylene. Optional ceramic liners for patients requiring superior wear characteristics or with metal allergy concerns.
  • Cementless: Press-fit femoral stem and acetabular shell, promoting biological ingrowth over time.
  • Cemented: PMMA (polymethyl methacrylate) utilized for patients with poor bone quality or other indications.
  • Hybrid: Cementless cup paired with a cemented stem for specific intraoperative preferences.
  • Primary hip replacement for degenerative joint disease, including osteoarthritis and inflammatory arthritis.
  • Traumatic or post-traumatic conditions leading to end-stage hip destruction or non-reconstructable fractures.
  • Revision surgeries addressing implant loosening, periprosthetic fractures, or wear-related complications.
  • Active local or systemic infections, severe untreated osteoporosis, or neurological/vascular conditions that preclude joint replacement.
  • Patients lacking sufficient bone stock to achieve stable fixation in either a cemented or cementless approach.
