Zimmer Biomet has officially launched the Avenue T transforaminal lumbar interbody fusion (TLIF) cage in the USA.
Avenue T incorporates VerteBridge plating. This is designed to facilitate simplified cage insertion and zero-profile, intradiscal fixation. It is intended to be implanted through a direct, minimally invasive approach.
Avenue T is the first and only posteriorly implanted cage with integrated, anti-migration fixation. It joins a family of cages with the company’s VerteBridge plating, including the ROI-C cervical cage, the Avenue L lateral lumbar cage and the ROI-A anterior lumbar interbody cage.
The cage and self-guided, curved VerteBridge plating are delivered in the plane of the disc through a streamlined technique. The VerteBridge plates are sterile packaged and pre-assembled on a PEEK cartridge. The cartridge is intended to simplify the technique, enabling the cage and plates to be loaded simultaneously on the Inserter.
The TLIF device is intended for use with autograft to facilitate fusion.
Once the cage is implanted, the Impactor advances both plates at the same time, reducing implantation steps. The unique anterior column fixation provided by the plating may permit the surgeon to select from a greater array of options for supplemental fixation.
Craig Chebuhar, an orthopaedic spine surgeon in Atlanta, USA who implanted one of the first Avenue T cages in the country, comments, “Transforaminal lumbar surgery is another attractive application for integrated plating. For my TLIF patients, I appreciate the additional fixation VerteBridge provides to the construct, all via a minimally invasive approach.”
The system is indicated for intervertebral body fusion of the lumbar spine, from L2 to S1. It should be used in skeletally mature patients who have had six months of non-operative treatment.
The device is intended for use at either one level or two contiguous levels for the treatment of degenerative disc disease (DDD) with up to grade I spondylolisthesis or retrolisthesis.
Avenue T is designed for use with or without integrated fixation. It must be used in conjunction with supplemental lumbar fixation cleared by the US Food and Drug Administration.
