Spine fusion is one of the most common procedures performed in spinal surgery. Several
surgical techniques can achieve a solid union, but the intertransverse posterolateral fusion
(PLF) is the most widely used. However, complications can develop when the bone graft
material used is insufficient to achieve the desired fusion. With its unique properties,
nanOss Bioactive can be mixed with bone marrow aspirate (BMA) and other graft materials to
obtain new bone growth during the healing process.
It is hypothesized that the use of nanOss Bioactive will result in fusion at 12 months, with
CT evidence of bridging trabecular bone, less than 3mm of translational motion, and less than
5 degrees of angular motion. In addition, patients are expected to see an improvement in
Oswestry Disability Index scores, VAS pain scores, and SF36 scores, while decreasing the use
of pain medication, returning to work, and finding satisfaction in the results of their
surgery.

Eligibility |
Inclusion Criteria: The patient can be included in the study if all of the following criteria are met; 1. is at least 18 years of age and skeletally mature 2. must have symptomatic spinal stenosis and/or spondylolisthesis or degenerative disc disease (DDD) at one or two adjacent levels from L2-S1 requiring a fusion 3. must have completed a minimum of three months of unsuccessful conservative, non-operative care 4. must have discogenic back pain with or without leg pain 5. DDD must be confirmed by MRI or CT scans followed by discography (if necessary) 6. must score at least 40 points on the Oswestry Disability Index 7. must score at least a 4 on a 10 cm Visual Analog Scale for back pain 8. must be able to comply with the protocol?s follow-up schedule 9. must understand and sign the informed consent document Exclusion Criteria: The patient must not exhibit any of the following criteria; 1. symptomatic at more than two levels 2. previous fusion surgery at any lumbar level with or without instrumentation (prior discectomy, laminotomy, laminectomy or nucleolysis at the operative (involved) level > 6 months is permitted) 3. more than 50% spondylolisthesis 4. lumbar scoliosis greater than 11 degrees 5. osteoporosis*, osteopenia, osteomalacia, Paget?s disease or metabolic bone disease. 6. spinal tumors 7. active arachnoiditis Pioneer Surgical Technology Confidential nanOss Bioactive Post Marketing Clinical Study: March 11, 2010 Page 8 8. fractures of the epiphyseal plate or fractures for which stabilization of the fracture is not possible. 9. Impaired calcium metabolism 10. active infection or surgical site infection 11. rheumatoid arthritis or other autoimmune disease 12. chronic steroid use (used steroids for one month within the last 6 months) or any medical condition that requires treatment with drugs known to interfere with bone healing 13. systemic disease such as AIDS, HIV, hepatitis (active), tuberculosis 14. morbid obesity defined as body mass index (BMI) >40 or a weight more than 100 lbs over ideal body weight 15. smokers unless the patient agrees to quit at least 2 weeks prior to and for the duration of the study, confirmed by a carboxyhemoglobin test prior to surgery 16. psychosocial disorders that would preclude accurate evaluation or has a history of substance abuse 17. active malignancy except non-melanoma skin cancer; history of any invasive malignancy unless treated and in remission for at least five years 18. documented allergies to porcine collagen or titanium 19. pregnancy, or interested in becoming pregnant in the next four years 20. participation in another investigational study within 30 days *Osteoporosis will be assessed at the time of the preoperative evaluation based on the patient?s history, physical examination and review of the radiographic evaluations. All patients at risk for osteoporosis must obtain a DEXA scan of the spine and hip to determine if the patient has severe osteoporosis. The definition of a patient at risk used by the National Osteoporosis Foundation includes the following: i. Premature menopause (< 45 years) ii. Prolonged amenorrhea (> one year) iii. Maternal history of hip fracture iv. Primary hyperparathyroidism or hyperthyroidism v. Chronic renal failure vi. Previous fragility fractures, particularly of the hip, spine or wrist vii. Patients who have ever taken corticosteroids in doses >7.5 mg/day for one year or more. Patients will be excluded if their bone mineral density (BMD) in the spine or hip is more than 1.0 standard deviation (SD) below the mean of normal adults in the presence of one or more fragility fractures indicating severe osteoporosis. If severe osteoporosis is diagnosed, the patient must be excluded from the investigational study. If the patient has osteoporosis or osteopenia, they may be included in the study if he or she meets the rest of the inclusion and exclusion criteria. |
