Lumbar Spine Degeneration
Conditions
Brief summary
This study is aimed at comparing the overall efficacy (clinical and radiographic) of Vivigen, a novel cellular allograft product, and rhBMP-2 when utilized in lumbar fusion procedures.
Detailed description
The purpose of this study is to compare the overall efficacy (clinical outcome and radiographic fusion) of Vivigen (cellular allograft product) and rhBMP-2 in patients who undergo a single level lumbar instrumented fusion. Specifically, when compared to their control group counterparts treated to rhBMP-2, we hypothesize that the intervention group administered Vivigen would, following surgery, experience: 1. Comparable mean postoperative leg/back pain score, where the pain scores are obtained using the numeric rating scale of 0-no pain, to 10-worst pain possible 2. Comparable inpatient length of stay (LOS) 3. Comparable postoperative Oswestry Disability Index (ODI) score (0-no disability, to 100-maximum disability possible), two weeks, 6 weeks, 3 months, 6 months, and 1 year postoperatively 4. Comparable fusion rates, evaluated via CT scan I year postoperatively
Interventions
The single level lumbar instrumented fusion patients assigned to this group will receive 5cc Vivigen and local autograft
The single level lumbar instrumented fusion patients assigned to this group will receive small kit rhBMP-2 with local autograft

Study design
Masking description
The surgical team, including the surgeons, will be blinded to the treatment options until decompression/instrumentation have been completed. The patients and all staff, including hospital nursing staff, case management, and physical therapists, will be blinded as to which bone graft treatment the patient received.
Eligibility
Inclusion criteria
1. Age 18 or older; 2. Diagnosed with lumbar degenerative/isthmic spondylolisthesis, degenerative disc disease with axial low back pain and neurologic symptoms, failed conservative treatment and eligible for a single level lumbar instrumented fusion; 3. Willing to provide informed consent, participate in study, and comply with study protocol.
Exclusion criteria
1. Pregnant or contemplating pregnancy prior to surgery; 2. Serious spinal conditions (e.g. spinal cord compression, cauda equina syndrome, spinal infection, spinal tumor, spinal fracture, inflammatory or systemic spinal arthritis); 3. Surgery involving more than 2 vertebral levels; 4. Worker's compensation or personal injury related to lumbar spine (treatment outcomes may be affected by patient's personal interests; could also run into potential issues with reimbursement). 5. Lactating women 6. Patients who have a known or suspected allergy to Gentamicin Sulfate, Meropenem, Vancomycin, Dimethyl Sulfoxide (DMSO), and Human Serum Albumin 7. Immune compromised patients

Outcome results
Mean Oswestry Disability Index (ODI) Score
The ODI is one of the most commonly utilized condition-specific measures of disability used in the management of spinal disorders (0-no disability, to 100-maximum disability possible)
Time frame: Up to 1 year post surgery
Population: Patients did not attend every follow up visit and then were ultimately lost to follow up. Study was also terminated early when the PI left his practice so on patients were never randomized in the control group.
| Arm | Measure | Group | Value (MEAN) |
|---|---|---|---|
| Intervention Group - 5cc Vivigen and Local Autograft | Mean Oswestry Disability Index (ODI) Score | ODI at Two weeks | 78.5 score on a scale |
