Study summary

Intra-annular injections of non-autologous fibrin for moderate to severe chronic low back pain (LBP).

Read the detailed description

The purpose of this study is to analyze data available in the PIs Regenerative Orthobiologics Registry (ROR) and corresponding patient charts that will either support or refute the efficacy of Intra-annular fibrin as treatment for moderate to severe low back pain. Additionally, we seek to retrospectively identify possible predisposing factors that are correlated with positive outcomes with respect to patient-reported pain and function.

What researchers measure

Primary outcomes

  1. Oswestry Disability Index (ODI)

    The Oswestry Disability Index (ODI) is a questionnaire used by clinicians and researchers to quantify disability for low back pain. Scale for the ODI is from 0 (best) - 100 (worst).

    Time frame: Two Years

Secondary outcomes

  1. Numeric Rating Scale (NRS)

    The NRS consists of a numeric version of the visual analog scale. It is labeled from zero to ten, with zero being an example of someone with no pain and ten being the worst pain possible. Scale for NRS is from 0 (best) - 10 (worst).

    Time frame: Two Years

  2. Visual Analog Scale (VAS) for back pain

    When responding to a VAS item, respondents specify their level of agreement to a statement by indicating a position along a continuous line between two end-points. Scale for VAS for back pain is from 0 (best) - 10 (worst).

    Time frame: Two Years

  3. Visual Analog Scale (VAS) for leg pain

    When responding to a VAS item, respondents specify their level of agreement to a statement by indicating a position along a continuous line between two end-points. Scale for VAS for leg pain is from 0 (best) - 10 (wors

    Time frame: Two Years

  4. PROMIS Physical Health

    The PROMIS Global-10 is a publicly available global health assessment tool that allows measurements of symptoms, functioning, and healthcare-related quality of life (HRQoL) for a wide variety of chronic diseases and conditions. Scale for PROMIS Physical Health is from 16.2 (worst) - 67.7 (best)

    Time frame: Two Years

  5. PROMIS Mental Health

    The PROMIS Global-10 is a publicly available global health assessment tool that allows measurements of symptoms, functioning, and healthcare-related quality of life (HRQoL) for a wide variety of chronic diseases and conditions. Scale for PROMIS Mental Health is from 21.2 (worst) - 67.6 (best).

    Time frame: Two Years

  6. North American Spine Society (NASS) for patient satisfaction

    The North American Spine Society (NASS) developed an outcome assessment instrument to measure diverse dimensions of the impact of lumbar spine problems. Scale range is from 1 to 4 (best to worst).

    Time frame: Two Years

  7. EURO Quality of Life (EuroQol)

    EuroQol is an instrument which evaluates the generic quality of life developed in Europe and widely used. Scale is from 0.33 (worst - 0.88 (best).

    Time frame: Two Years
