Orthopedic Solutions for Healthcare Professionals

WHY ORTHO SPECIALISTS CHOOSE OUR POLYMER SOLUTIONS

Devices made from our high performance polymers are proven to offer improved biomechanics and comfort.

BONE-LIKE MODULUS

PEEK-OPTIMA^TM features a modulus similar to human bone which reduces stress shielding and leads to improved physiological loading.¹

BIOCOMPATIBILITY

PEEK-OPTIMA^TM - biocompatibility in conformance with ISO 10993-1 for use in the manufacture of medical devices for long-term implantable orthopedic applications.²

WEAR PERFORMANCE

PEEK-OPTIMA^TM polymer’s superior wear performance offers an alternative load-bearing material to metal designed to address metal ion concerns.³

Clinical evidence

Case study

Three-Year Clinical and Radiological Results of a New Flexible Horseshoe Acetabular Cup

Field, et al. reports on a clinical trial of a MOTIS™ acetabular cup. Overall, all 25 acetabular cups exhibited excellent fixation at up to 3 years and 19 patients have shown positive results.

Early Results of a New Rotating Hinge Knee Implant

A. Giurea, et.al (2014) showcase excellent clinical results of the EnduRo total knee arthroplasty (TKA) made of PEEK OPTIMA polymer. No premature material failure or unusual biological response to the new bearing material could be detected.

Peek-optima™ natural

PEEK-OPTIMA™ polymer blends proven performance with superior wear, safety and comfort and has properties that are closer to bone than metal, so there is less stress shielding.¹Since 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.
