Outcome Measures

Primary Outcomes (2)

  • Number of adverse device effects

    Adverse device effects related to the processing of the platelet rich plasma product (such as hardware failures/malfunctions, software errors, disposable set equipment malfunctions, processing errors, automatic self-test/calibration errors, variations in hematocrit level in final product, variations in total volume of PRP concentrate produced, etc.)

    Day 0 (Day of procedure)

  • Number of suspected acute adverse reactions to the treatment

    Suspected adverse reactions to the treatment based on evaluations including follow-up physical examinations, labs and assessment of clinical signs and symptoms.

    Day 0 to Day 14

Study Arms (1)

PRP Injection Arm

EXPERIMENTAL

The FDA cleared Angel® Concentrated Platelet Rich Plasma System and Angel® cPRP Processing Set will be used to process the PRP. The targeted final PRP volume of 6 ml will be injected in up to 4 facet joints (2 levels) at 1.5 ml per joint.

Eligibility Criteria

Age22 Years - 70 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Clinical and radiographic (MRI, CT or lumbar x-ray) evidence of symptomatic facet arthropathy involving the bilateral bottom two facets (e.g., L4-5 or L5-6 and L5-S1 or L6-S1).
  • Positive response, defined according to current clinical standards for the diagnosis of facet-mediated low back pain as greater than or equal to 75% pain improvement (as reported by patient) to diagnostic medial branch nerve blocks, one block with lidocaine and the other with bupivacaine.
  • Low back pain VAS score of greater than or equal to 5 at the clinical visit just prior to the first medial branch nerve block.

You may not qualify if:

  • Prior facet related procedure (intraarticular corticosteroid injection, radiofrequency ablation (RFA)) in last 6 months or prior fusion in the bottom two facets.
  • Current opioid use of greater than 50mg oral morphine milligram equivalents per day.
  • No advanced imaging (MRI, CT or lumbar x-ray) of the lumbar spine within the last 6 months.
  • BMI \> 34.99 (WHO class I obesity).
  • Active systemic or local infection as evidenced by fever \>100.4 degrees Fahrenheit, or any other clinical signs or symptoms of infection within 24 hours of the procedure.
  • On anticoagulation drug and has been on hold for less than 7 days prior to the investigational procedure.
  • Imaging evidence of high likelihood of failure for intra-articular injection in the opinion of the PI or delegate review of MRI, CT or lumbar x-ray imaging.
  • History of chronic thrombocytopenia (or pre-operative platelet count less than 195,000 per μl).
  • Undergoing chemotherapy at time of injection.
  • Pregnant or breastfeeding.
  • Use of illicit drugs within 30 days prior to study entry.
  • NSAID use during the pre-procedural period (one week before Treatment Day 0).
  • Preoperative hematocrit less than 36%.
  • History of hemodynamic instability or inability to maintain stable oncotic pressure.
  • History of prolonged clotting times.
  • +3 more criteria
