Investigational Device Exemption (IDE) Lumbar Clinical Trial
Prospective, Multi-center, Randomized, Controlled IDE Clinical Trial: Freedom Lumbar Disc (FLD) One-Level IDE Pivotal Study in the Treatment of Lumbar Degenerative Disc Disease completed in 2015
The Freedom Lumbar Disc is indicated for spinal arthroplasty in skeletally mature patients with single level, symptomatic degenerative disc disease (DDD) from L3-S1. This was a prospective, multi-center, randomized, controlled trial. 300 patients with DDD was randomized to disc arthroplasty with the FLD device or the ProDisc (control device). The overall purpose (objective) of this trial was to collect clinical data to demonstrate the safety and effectiveness of FLD used for the treatment of symptomatic lumbar degenerative disc disease compared to the control device.
