SCYON Total Hip Replacement

Stem Fixation with Locking Screws

The SCYON THR stem achieves permanent anchorage through bony ongrowth from the medial cortex without coupling to the lateral cortex.
This results in near-physiological loading of the proximal femur, i.e. absence of stress shielding.
The incidence of aseptic loosening is greatly reduced compared with conventional THR systems. (based on 14 years of canine clinical data)

Compliant Shell for Bone Ingrowth

The perforated, hydraulically open, highly compliant, double-shelled titanium backing provides for rapid and consistent integration of the cup into the acetabulum.

Wear Reducing Geometry of Cup Liner

UHMWPE cup liner articulating surface geometry significantly reduces the polyethylene wear and thus the risk of bone lysis mediated aseptic loosening.

SCYON instrumentation and implant design reduce, if not eliminate, pressure increases in the intramedulary canal that could result in pulmonary fat embolism.

SCYON solutions for 3 main failure mechanisms of Total Hip Replacements:
1) Loosening of the femoral stem component

  • Immediate and permanent proprietary locking-screw fixation to the medial cortex.
  • Near-physiological loading of the proximal femur – absence of stress shielding.
  • Rough blasted surface for micro-interlock.
  • 2) Loosening of the acetabular cup component
  • Proprietary hydraulically open, compliant, double shell, titanium backing for the cup.
  • Rapid bony ingrowth into a highly compliant acetabular cup.
  • Perforated outer shell allows good bone ingrowth.
  • Minimal disruption of diaphysial cancellous bone.
    3) Wearing out of the joint bearing material
  • Proprietary geometric feature allows significant wear reduction of the UHMWPE cup liner.
  • Absence of wear-particle induced bone lysis.
    Plus, although less talked about, a very important advantage is the reduction of the risk of complications due to fat embolism.
  • SCYON instrumentation and implant design reduce, if not eliminate, pressure increases in the intramedulary canal that could result in pulmonary fat embolism.
