The feedback we continue to receive from surgeons using SupStance® demonstrates that Invibio's PEEK-OPTIMA Image Contrast Grade is well poised to become the ‘gold standard’ for clinicians who want to visualize the entire implant post operatively

Designed to meet spinal surgeons’ exacting needs, the SupStance® Small PEEK VBR (Vertebral Body Replacement) System from Creaspine® is the first FDA-approved one-piece visible PEEK corpectomy device. The innovative device uses PEEK-OPTIMA® Image Contrast Grade polymer from Invibio® Biomaterial Solutions to enable whole silhouette visualization of the implant per and post-op.
SupStance Small is a VBR device designed for use in the thoracolumbar spine to replace a collapsed, damaged or unstable vertebral body during tumour or trauma management procedures.
According to Creaspine’s Business Development Director Franck Tricot, assessing surgeons’ needs is the starting point of the France-based company’s project development process. For SupStance, key surgeons’ needs were identified around the areas of distract and fit, visibility and fusion.
“We were looking for a unique and original way to allow surgeons to visualize the whole silhouette of the implant, to see their implants pre and post operatively, and to more easily assess fusion. Invibio’s PEEK-OPTIMA Image Contrast Grade rapidly became our preferred and obvious choice – it provides imaging visibility, and allows for bone growth/fusion visualization and follow-up, as well as implant positioning checks (versus the canal and endplates),” said Franck Tricot.
According to Franck Tricot, another key factor in Creaspine’s selection of PEEK-OPTIMA was the biocompatible polymer’s proven history.
In addition to the visibility benefits, SupStance was also designed with large lateral windows to provide continuous bone reconstruction from cranial to caudal and laterally, whilst optimizing bone graft volume usage. Further, SupStance implant incorporates grooves and distracter tips that can slide down these grooves. “What surgeons need for corporectomy cases is an efficient and sufficient distraction of the segment and we also answer to this need with SupStance. Because the distracter applies force as needed, the system is in essence distractible in situ with no over-distraction,” said Franck Tricot.
Positive results of postoperative clinical cases were published in the European Spine Journal in September 2009.
The FDA approved the SupStance Small PEEK VBR System in May 2008. Today, more than 1,500 VBR cages made of PEEK-OPTIMA Image Contrast Grade have been released on the US and international markets.
Throughout their clinical experience, reports Franck Tricot, surgeon users have valued visible PEEK because it enhances X-ray visibility, shows no artefacts on MRI, and enables improved fusion follow-up.
“Leveraging Creaspine’s clinical success in the VBR segment, spine surgeons can now enjoy similar benefits in the cervical and lumbar interbody fusion segment. The feedback we continue to receive from surgeons using SupStance® demonstrates that PEEK-OPTIMA Image Contrast Grade is well poised to become the ‘gold standard’ for clinicians who want to visualize the entire implant post operatively,” said Franck Tricot.
