Brief Summary:
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.

Primary Outcome Measures :
  1. Visual Analog Scale (VAS) for Leg Pain [ Time Frame: Minimum 24 months post procedure ]
    Patient demonstrates a reduction in leg pain from baseline of at least 20 mm on a 100 mm visual analog scale (VAS)

  2. Zurich Claudication Questionnaire (ZCQ) [ Time Frame: Minimum 24 months post procedure ]
    Clinically significant improvement from baseline defined by a minimum decrease of .5 as measured by the Zurich Claudication Questionnaire for both Symptom Severity(SS) and Physical Function (PF) scores

  3. Major Device Related (MDR) Complications [ Time Frame: Minimum 24 months post procedure ]
    Patient experiences no major device-related complications

  4. Revision, Reoperation, or Removal [ Time Frame: Minimum 24 months post procedure ]
    The treated level did not require surgical revision, reoperation, removal, or supplemental fixation.

Secondary Outcome Measures :
  1. Oswestry Disability Index (ODI) [ Time Frame: Minimum 24 months post procedure ]
    Changes from baseline in function scores (Oswestry Disability Index)

  2. Presence (control) or Absence (Stabilimax)of fusion [ Time Frame: Minimum 24 months post procedure ]
    Presence (control patients) or absence (Stabilimax NZ® patients) of fusion at 24-months post procedure

  3. Adverse Events (AE) [ Time Frame: Minimum 24 months post procedure ]
    safety will be assessed by quantification of the incidence of all adverse events observed during the study period by type.

  4. Physician Satisfaction Scale [ Time Frame: Immediately post procedure ]
    Characterization of the physician's satisfaction with clinical implantation of the therapeutic device by use of rating scales.
