Outcome Measures

Primary Outcomes (5)

  • Spinal Fusion Grade at 1 Year Via CT Scan

    Spinal fusion grade refers to the assessment of how well vertebrae fuse together after surgery, often evaluated using imaging like CT scans or radiographs. Grades typically range from complete fusion (Grade I) to non-union or pseudarthrosis (Grade IV), indicating varying degrees of bone healing and stability.

    Post Operative 1 Year

  • Change in Oswestry Disability Index (ODI) Score

    The Oswestry Disability Index (ODI) score ranges from 0 to 100, with higher scores indicating greater disability. A score of 0% represents no disability, while a score of 100% represents complete disability. The ODI is often interpreted using categories: 0-20% (minimal disability), 21-40% (moderate disability), 41-60% (severe disability), 61-80% (crippling), and 81-100% (bedridden or functional impairment).

    Pre-operative, Post Operative 1 Year

  • Short Form Health Survey (SF-12)

    The SF-12 is a shorter version of the SF-36, designed to assess health-related quality of life. Scores range from 0 to 100. Scores above 50 indicate better-than-average health-related quality of life for that component. Scores below 50 indicate below-average health-related quality of life.

    Pre-op, Post Operative 1 Year

  • Change in Numeric Pain Rating Scale Score From Baseline (Pre-op) and 1 Year Post Operative

    The numeric pain rating scale (NRS) is a tool used to assess pain intensity, commonly using a scale of 0 to 10, where 0 indicates "no pain" and 10 represents the "worst pain imaginable"

    Pre-op, Post Operative 1 Year

  • Length of Stay in Hospital, Measured in Days

    Post Operative 1 Year

Study Arms (2)

BMAC & Allograft

ACTIVE COMPARATOR

Subjects will be treated with bone marrow aspirate concentrate (BMAC) and allograft during posterior lumbar/lumbosacral spinal fusion. During lumbar spine surgery, 12 teaspoons of bone marrow will be taken (aspirated) from one side of hip bone. This may be repeated on the other side of hip bone for a total of 12, 24, or 36 teaspoons of bone marrow total taken from your hip bone depending on the decision made by the surgeon. The bone marrow will then be concentrated with a machine for 15 minutes to a final volume of 2, 4, or 6 teaspoons of BMAC. BMAC will be combined with packed allograft bone chips using another machine to produce two or three constructed bone logs. The bone logs will be laid along the backside of the spine and between each vertebral body.

Procedure: BMAC & Allograft

Iliac Crest Bone Graft

ACTIVE COMPARATOR

Subjects who are in the Iliac Crest Bone Graft arm will be treated with Iliac crest bone grafts (ICBG) during posterior lumbar/lumbosacral spinal fusion. During lumbar spine surgery, the surgeon will make an incision to expose the iliac crest (hip bone), and cutting out the segments of the bone that will be needed, based on the decision of the surgeon. The bone chips will be laid along the backside of the spine and also between each vertebral body where the bone will fuse into place. When the bone becomes solid/fused, there is no movement in the fused spine.

Procedure: Iliac Crest Bone Graft

Interventions

Use of Allograft infused with adult stem cells from the bone marrow aspirate harvested from the iliac crest during posterior lumbar/lumbosacral spinal fusion.
