Breakthrough implantable PEEK-OPTIMA™ polymers for fracture fixation

A leading innovator in trauma solutions

Delivering next generation technologies for fracture fixation and reducing implant failure, our carbon fiber composite trauma solutions are benefiting patients worldwide with a less stiff material compared to metal1.

Setting the standard for
for over 20 years

More than twenty years ago, the biocompatible PEEK-OPTIMATM Natural polymer quickly became the material of choice in interbody fusion and developed a successful clinical track record. 
Today, approximately 15 million PEEK-OPTIMATM devices are implanted worldwide. 

Challenging patient health risk factors

Increasing global rises in high risk conditions that reduce the ability to heal after a fracture. Studies show that there is an elevated non-union risk associated with severe fractures in people with a high body mass index, and a history of smoking, and alcoholism.5

The rising cost of complications 

Adverse events are 3 times more likely in trauma patients than other orthopedic patients, which is leading to more frequent and higher costs to revise and deal with complications.6

Reducing risk through device design

Medical device companies are seeking a new generation of high performance fixation devices that can offer adequate fatigue strength to withstand loads through the healing process, especially in patients with risk factors for implant related complications.


Our biocompatible carbon fiber composite material, PEEK-OPTIMA Ultra-Reinforced polymer, offers an alternative to metal for fracture fixation devices for high-load implant applications
Craniomaxillofacial plates

Patient-specific craniomaxillofacial implants

PEEK-OPTIMA high performance polymer is a strong, permanent, functional alternative to traditional structural materials like metal that can be used to manufacture custom cranial implants. PEEK-OPTIMA’s biomechanical properties are similar to bone, result in better clinical outcomes and have improved cosmetic satisfaction compared to titanium.

Cerclage wires have been the standard of care for sternotomies but can result in loosening and patient discomfort when coughing. Poor bone quality in geriatric patients can also result in wire cut through and instability post operatively. Studies have shown rigid fixation results in better outcomes compared to standard cerclage wires. PEEK-OPTIMA polymers have been used to innovate in this space, with OEMs developing new metal-free technologies for fixation plate, ties and zips.

PEEK-OPTIMA Ultra-Reinforced combines the high-performance material properties of PEEK-OPTIMA Natural polymer with the strength imparted by continuous carbon fibers.
Intermedullary nails

Intermedullary nails

PEEK-OPTIMA Ultra-Reinforced enables semi-rigid fixation with the potential for improved fatigue and imaging properties over metal2-4. In intermedullary nails, there is a greater percent of femoral nail cases healed at 6-week time period compared to reported rates of metal, and pain-free ambulation without assistive devices in 4-7 weeks in patients with tibia and fibula nails2-4

PEEK-OPTIMA™ polymer blends for proven performance with superior wear, safety and comfort. Since Invibio introduced PEEK-OPTIMA as the first implantable PEEK polymer in 1999, it has earned the confidence and gained the acceptance of the global medical community.
More than twenty years ago, the biocompatible PEEK-OPTIMATM Natural polymer quickly became the material of choice in interbody fusion and developed a successful clinical track record.  Today, approximately 15 million PEEK-OPTIMA polymer devices are implanted worldwide. This high-performance, implant-grade polymer serves as the foundation for the PEEK-OPTIMA product family.

All the benefits of PEEK-OPTIMATM Natural plus Hydroxyapatite (HA) crystals embedded throughout the material, a well-known osteo-conductive material. Unlike interbody fusion devices that are coated, PEEK-OPTIMATM HA Enhanced devices have hydroxyapatite crystals on all surfaces which results in earlier bone on-growth and greater new bone formation on a fully osteoconductive implant. Key benefits include:

  • Enhanced bone apposition1,
  • Greater new bone formation2
  • Higher quality of new bone bridging2.
PEEK-OPTIMATM Image Contrast offers all the performance advantages of the clinically proven and highly utilized PEEK-OPTIMATM Natural, with one unique difference: it allows for tailored radiolucency that can be optimized for application-specific image guidance and post-operative healing assessment requirements.

A carbon fiber reinforced PEEK polymer compound to increase strength while reducing stress shielding by more closely matching cortical bone stiffness. Short carbon fibers are dispersed within the PEEK-OPTIMATM Natural matrix enhancing mechanical and physical properties for more demanding load-bearing implants and applications. Benefits include3:

  • Fiber-to-matrix bond strength provides higher strength than PEEK-OPTIMA Natural Polymers
  • Bone-like stiffness can reduce stress shielding by more closely matching cortical bone stiffness
  • Extensive history of use in FDA 510(k) cleared, long-term implantable devices 

An innovative composite formed by continuous carbon fibers dispersed within the PEEK-OPTIMA Natural polymer matrix to enhance mechanical strength and stiffness.

Benefits include:

  • Excellent fatigue resistance and structural strength for device longevity4
  • Tailored stiffness for design flexibility4
  • Radiolucent, offering circumferential visibility of the surgical site before and after the procedure.
