Outcome Measures

Primary Outcomes (1)

  • Removal/revision or supplemental fixation of the graft material requiring reoperation at the index level, Safety (adverse events), Fusion "success" based on X-rays, Change from baseline in neurological exam scores and ODI scores

    12 months post surgery

Secondary Outcomes (1)

  • Volume of blood loss/transfused blood during surgery, Blinded independent assessment of fusion by CT and other radiographic assessments, Change from baseline in pain scores using VAS and change from baseline in SF-36 v2â„¢ total and subscale scores

    12 months post surgery

Eligibility Criteria

Age18 Years - 70 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Documented diagnosis of DDD requiring single level fusion (L2-S1) with up to Grade I Spondylolisthesis
  • Have a preoperative screening qualifying VAS and ODI scores
  • Be a skeletally mature male or a non-pregnant, non-lactating female, age 18 -70 inclusive
  • Have not been sufficiently responsive to at least 6 months of non-operative treatment prior to study enrollment

You may not qualify if:

  • Are female subjects who are pregnant or nursing, or women planning to become pregnant during the first year (12 months) following the surgery
  • A history of previous surgery in the lumbar spine with or without attempted fusion
  • Grade II or greater spondylolisthesis
  • More than 0 degrees of kyphosis at the operated disc space
  • Evidence of scoliosis in the lumbar region of more than 10 degrees
  • Collapsed disc space with bridging osteophytes
  • A systemic or local infection at the site of surgery
  • An acute fracture of the spine at the time of enrollment in the study
  • An active history of systemic malignancy
  • A medical condition, serious intercurrent illness, or extenuating circumstance that, in the opinion of the Investigator, would preclude participation in the study
  • A known hypersensitivity to any of the components of the product or a known titanium allergy or a known allergy to polyetheretherketone (PEEK)
  • A history of any autoimmune disease, such as, systemic lupus erythematosus, Addison's disease, Crohn's disease, or rheumatoid arthritis
  • A history of any severe allergy or anaphylaxis, or a history of hypersensitivity to protein pharmaceuticals, or have had any previous exposure to a protein pharmaceutical
  • Are receiving treatment (before or during surgery) with a drug (e.g., steroids, methotrexate, etc.) that interferes with bone metabolism or are being treated with a bone growth stimulator
  • A medical condition requiring radiation, chemotherapy or immunosuppression, or a medical condition requiring systemic corticosteroids
  • +12 more criteria
