Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Have provided consent for research by signing the Institutional Review Board approved Informed Consent;
  2. Have given appropriate operative consent for a decompressive lumbar (L1-S1) laminectomy procedure as standard of care;
  3. Are skeletally mature, and are at least 18 years of age;
  4. If female, are not pregnant;
  5. Agree to adhere to post-surgical medically prescribed activity limitations and/or physical rehabilitation.

Exclusion Criteria:

  1. Previous surgery at the target or adjacent vertebral levels;
  2. More than two intervertebral levels to be treated by the laminectomy procedure;
  3. Found to be inappropriate candidates for facet fixation using the VerteLoc system;
  4. Require additional and/or other surgical technique and/or approach to the laminectomy at the index level(s), which may in the opinion of the Primary Investigator confound measurement of outcome variables;
  5. Has a medical disorder or is receiving medications that would be expected to interfere with osteogeneses,
  6. Active malignancy or patient with a history of any malignancy (except non-melanoma skin cancer) with recurrence within 5 years of surgery;
  7. Active local or systemic infection or history of local or systemic infection, immune-deficiency, uncontrolled medical conditions, which in the opinion of the Investigator may increase patient risk or confound fusion results;
  8. BMI >40% ;
  9. History of tobacco smoking within the past 6 months;
  10. Has a history of alcoholism, medication or drug abuse, psychosis, is a prisoner, and/or has a personality disorder, poor motivation, emotional or intellectual issues that would likely make the patient unreliable for participation in the study;
