Applications

Applications

Used in applications such as hip cups, rotating-hinge knees and knotless shoulder anchors, our metal-replacement solutions are reshaping orthopedics to deliver greater long-term patient satisfaction. From discovering new ortho device opportunities to supporting market adoption, Invibio is here to help you every step of the way in this highly regulated environment.

Hip arthroplasty

Our durable biomaterial, PEEK-OPTIMATM Wear Performance, addresses the need for new, longer-lasting designs for younger and more active patients. Excellent wear resistance and exceptional structural strength make it an ideal choice for hip cups that support bone-conserving concepts.4-6 Benefits include:

  • metal-free load-bearing material designed to address metal ion concerns
  • a modulus similar to human bone, which reduces stress shielding and leads to improved physiological loading
  • accommodates both standard and new implant fixation technologies
  • radiolucent and compatible with common imaging technologies for improved visualization for placement and post-operative follow-up2
Knee arthroscopy

Knee arthroscopy

Tibial and femoral interference screw systems made from PEEK-OPTIMATM polymers provide many structural properties needed when designing the next generation fixation system:

  • Cortical and cancellous thread forms can be molded or machined to provide the ideal bite for the target boney substrate
  • Strength to withstand the high torque loads encountered during graft impingement in the bone tunnel
  • Are radiolucent, allowing simple post-operative assessment of repairs before final tensioning and closure using standard imaging techniques2
  • Bio-inert to reduce the risk of patient reaction to devices implanted in the body
