The MAVERICK™ is a two piece metal-on-metal artificial disc design made of chrome cobalt that incorporates a more posterior center of rotation. Metal-on-metal wear for the MAVERICK™ ball and socket implant, that is semi constrained, has been tested extensively and there is essentially no metal wear at 31.5 years of simulated loading. This artificial disc is not currently FDA approved in the United States.
The Kineflex L is a metal-on-metal artificial disc design made of chrome cobalt. This disc incorporates some of the design features of the Charite and the Maverick discs. The Kineflex L is a three-piece implant with a posterior center of rotation. This disc is not currently FDA approved in the United States.
The FLD is a one-piece total artificial disc replacement device intended to relieve low back pain by replacing intervertebral discs that have been damaged by degenerative disc disease. The FLD device has been used in England and Germany in 50 patients in a clinical study. Researchers are still studying the long term effects of the FLD in these patients.

The coflex-F implant is an alternative to pedicle screw fixation as an addition to interbody fusion. This minimally invasive lumbar fusion device provides segmental stability and contains all the advantages of an interspinous implant. The rigid connection allows for better fixation. You may learn more at the Paradigm Spine site or read about the coflex-F® implant.
The ProDisc-L was part of a FDA IDE study between October 2001 and June 2003. There were 232 patients at 17 sites across the United States. The ProDisc received FDA approval in 2006. The ProDisc is a spherical joint articulation. The endplates are composed of chrome cobalt, which articulates with an ultra-high molecular weight polyethylene.
