Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The Kineflex Spinal System is no worse than the Charite Spinal System in patients with single level degenerative disc disease at L4/5 or L5/S1.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The Kineflex disc is a 3-piece modular design consisting of 2 cobalt chrome molybdenum (CCM) end-plates and a fully articulating CCM core. The system is available in 3 foot print sizes.

* Previous thoracic or lumbar fusion
* Documented abnormal abdominal vessel or muscular/fascial pathology or morphology
* Degenerative spondylolisthesis
* Ischemic (spondylolytic) spondylolisthesis
* Spondylitis
* Documented significant spinal, foraminal or lateral stenosis
* Severely reduced disc space height
