Zimmer introduces a new porous metal interbody implant for lumbar spine


Zimmer Holdings introduced the TM Ardis Interbody System, a new porous metal interbody implant for lumbar spine at the 2012 SpineWeek meeting in Amsterdam, Netherlands. 

The TM Ardis Interbody System extends the applications of Zimmer’s proprietary Trabecular Metal Technology.

TM Ardis is indicated for use as an intervertebral body fusion device at one or two contiguous levels in the lumbosacral region (L2-S1) in the treatment of degenerative disc disease with up to Grade 1 spondylolisthesis or retrolisthesis at the involved level(s). The system is implanted using a posterior or transforaminal approach and is intended to be used singly or in pairs with supplemental fixation.

“The TM Ardis system is the latest innovation from Zimmer Spine, and we are excited to make this unique implant available to European surgeons and their patients,” said Steve Healy, president, Zimmer Spine. “This system, which incorporates Trabecular Metal Technology, is truly differentiated and we are confident it will offer clinical advantages in the treatment of degenerative disc disease.”

Leveraging the unique properties of Trabecular Metal, Zimmer designed the TM Ardis implant with a large surface area available for biologic fixation which means that the Trabecular Metal material of the implant can more evenly distribute the load and decrease the risk of stress shielding. The TM Ardis implant also features an updated, anatomical shape which allows the implant to be inserted into the disc space more easily.
