“Healthcare globally is under pressure to control costs which is why Invibio offers PEEK-OPTIMA spinal rod components to the manufacturer. Compiling evidence that supports the safety and clinical benefits of our materials enables us to also provide an efficient route to market for our customers in terms of manufacturing and regulatory clearance. We look forward to working with our customers to achieve clearance for semi-rigid systems in order to offer improved options for surgeons and ultimately patients,” concluded Devine.
“PEEK-polymer solutions are widely recognised for spinal interbody fusion and are frequently used. The versatile PEEK-OPTIMA has a modulus close to that of human bone, and this allows it to be a natural bridge between very rigid metal implants, such as the titanium constructs, and more dynamic approaches. In fact, PEEK-polymer implants offer numerous benefits, including radiolucency, which of course metals don't allow, whilst retaining the stability of titanium,” commented Dr. Thierry Desjardins, Neurosurgeon (Cagnes-sur-Mer, France), who has been using PEEK-OPTIMA spinal rods since June 2011 and has always been reluctant to use too rigid a system as this could accelerate degeneration at adjacent spinal segments.
PEEK-OPTIMA polymer based stabilization, on the other hand, effectively functions as a 'bridge' approach. Rods made from the material have sufficient strength to reduce the range of motion2,3 in order to stabilize the treated segment4, but possessing a modulus similar to that of cortical bone, they still allow physiological movement on adjacent upper and lower segments.3 As a result, clinical results increasingly suggest that PEEK-OPTIMA spinal rod components preserve or slow down the degeneration of adjacent discs.5 As a consequence, patients may benefit from improved load sharing to encourage fusion,2,6,7 and more physiologic loading at adjacent levels, which may decelerate degeneration.8,9
