With over twenty years of clinical history, PEEK-OPTIMA polymers were the first medical-grade PEEK used in spinal fusion surgeries offering distinct clinical advantages due to its inherent properties including:
The benefits of spinal arthroplasty compared to fusion for adjacent segment disease up to five years after surgery remains controversial1. Yet cervical arthroplasty remains a viable option for patients who wish to preserve range of motion following surgery. Histological analysis of current generation spinal arthroplasty devices has shown evidence of both metallic and polymeric wear debris, frequently with inflammatory cells in the surrounding tissues2.
PEEK-OPTIMA has an elastic modulus similar to cortical bone which may make it a preferred material for spinal arthroplasty devices.
Preliminary dynamic testing indicates that spinal arthroplasty devices made with PEEK-OPTIMA™ Natural or PEEK-OPTIMA™ Reinforced may generate significantly lower wear rates and particulate loads compared with traditional couplings.3-5 In addition, taking into account the particulate loads, both in-vitro and animal studies have suggested that PEEK-OPTIMA Natural and PEEK-OPTIMA Reinforced particles elicit a reduced biological response compared with UHMWPE.6-7
Unlike metals and other polymers, PEEK-OPTIMA is inherently radiolucent and provides improved healing site visualization.
