The intent of this study is to complete the collection of clinical data on subjects enrolled in the Stabilimax Dynamic Spine Stabilization IDE clinical trial (#G060214) sponsored by the now defunct Applied Spine Technologies Inc . The Applied Spine assets, including the clinical trial data, were acquired by Rachiotek, LLC in 2010. When Applied Spine ceased their funding of the trial, a number of enrolled patients had not yet completed the two year follow-up visit defined as the study endpoint in the clinical investigation plan. No additional patient treatment is required to complete the study. Rachiotek has interest in pursuing IDE approval for a new study and the information collected in this study is essential for supporting the new Investigational Device Exemption application.

Inclusion Criteria:

• Any patient that after having met all of the inclusion/exclusion criteria identified for the Stabilimax Investigational Device Exemption study had enrolled in the Stabilimax Investigational Device Exemption study and were implanted with the Stabilimax NZ or the control device.

Exclusion Criteria:

• Any patient that has had the device removed and the adverse event follow-up report stated that the event was resolved. This applies only if the patient was formally withdrawn from the study at that time.
