"The Kineflex devices are weight-bearing implants consisting of two keeled endplates and one semi-constrained, fully articulating CCM core. The Kineflex is supplied sterile. The Kineflex endplates and the core are manufactured from cobalt chrome molybdenum alloy (ASTM F799) with titanium (Ti) plasma spray coating (ASTM F1580) on the surfaces of the endplates. Surgical instrumentation is produced from stainless steel (ASTM F899) The Kineflex intervertebral arthroplasties are indicated in skeletally mature patients for reconstruction of the disc in the lumbar spine following single-level discectomy for intractable radiculopathy and/or myelopathy The implant is intended to restore segmental stability and recreate normal vertebral body spacing while preserving motion in the spine. Incorrect placement can affect clinical outcome and possibly result in device subsidence and/or failure."
