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

Inclusion Criteria:

  • Are 18 (eighteen) years of age or older at the time of surgery.
  • Require spinal fusion using TLIF, PLF or PLIF, with the use of an interbody spacer, at 1 to 3 levels between L3-S1.
  • Willing and able to return for the scheduled follow-up visits, follow post-operative instructions and undergo the required radiographic exams (A/P, Lateral Neutral and Lateral Flexion/Extension X-rays) for up to 3 time points between 6 months and 24 months post-surgery (6±2 months, 12±3 months and 24±4 months post-surgery), including one CT-scan at 12±3 months.
  • Unresponsive to conservative care over a period of at least 6 months or has signs and/or symptoms that mandate urgent surgical intervention.

Exclusion Criteria:

  • Are long term users of medications (i.e. steroids greater than 2-weeks) that are known to inhibit fusion or bone metabolism at any time within 6 months prior to surgery. Exceptions are inhaled steroids for asthma treatment (i.e. patients on inhaled steroids are allowed), or epidural steroid injections.
  • Are taking immunosuppressive agents (Cancer chemotherapy, treatment with Disease Modifying Anti-rheumatic drugs (DMARDs) or any similar immunomodulating drugs) or are treated with Growth Factors or Insulin at any time within 6 months prior to surgery.
  • Are being treated with radiotherapy.
  • Are having medical conditions, known to impact bone metabolism, such as Paget's disease, osteoporosis.
  • Are smokers and/or nicotine/tobacco users.
  • Are pregnant, lactating or women wishing to become pregnant.
  • Are a prisoner.
  • Are currently participating in an investigational drug or another device study that has not completed the primary endpoint or that clinically interferes with the study endpoints.
  • Prior spine surgery at the index level except posterior decompressive surgery where the posterior elements are preserved e.g. facet saving techniques such as discectomy, laminotomy, and intradiscal procedures.
  • Use of any other bone graft or bone graft substitute in addition to or in place of Accell Evo3® with the exception of local autograft and/or cancellous bone chips.
  • Use of routine prophylactic NSAIDS for 3 months post-operatively, but low dose concomitant pain medications e.g. aspirin should be continued and recorded on the Concomitant Pain Medications case report form (CRF).
