Fule, Beijing develops new hybrid PEEK-titanium spinal implant solution

Fule Science & Technology Development Co. Ltd, based in Beijing, specialized in the research, development, and production of orthopaedic products, has developed the first domestic expandable hybrid cage called ‘Uplifter’, whose constituent materials are Invibio’s PEEK-Optima Natural polymer and titanium.

The new product is officially known as an ‘expandable anterior lumbar interbody fusion device,’ that can be used to treat various forms of degenerative disc disease, nerve root-canal stenosis, and lumbar spondylolisthesis. The ‘Uplifter’ was displayed at the 11th Congress of the Chinese Association of Orthopaedic Surgeons (CAOS) held in partnership with the North American Spine Society (NASS) in China was highly praised by the delegates.

Dr Patrick C. Hsieh, from the USC Spine Center in Los Angeles, during a live demonstration on a cadaver at the Congress, presented the benefits of the procedure and the use of PEEK in the device, including radiolucency, explaining that this assists in accurate fusion assessment as well as has a track record of excellent long-term clinical results and radiographic fusion rates.

Dr. Xifeng Zhang, from Beijing 301 Hospital in his review of clinical applications and results associated with Direct-Lateral Lumbar Interbody Fusion, supported, “PEEK has been used for interbody fusion devices for many years. Both, the literature and my personal experience indicate that PEEK provides better clinical outcomes compared with titanium-only approaches in spinal fusion. There is a higher fusion rate and lower subsidence.”

Fule collaborated with Invibio, part of the Victrex plc group of companies, and a leading supplier of biomaterial solutions, including PEEK-Optima polymers to medical device manufacturers in the development of the new cage. According to Fule, the next step is the development of spinal fusion devices with PEEK-OPTIMA HA Enhanced.
