Participant Flow

51 participants between the ages of 18 and 80 years old with chronic low back pain and a diagnosis of sacroiliitis were selected for this single center clinical trial. The Setting was a privately owned physical medicine and rehabilitation clinic.

Measure
Platelet Rich Plasma Joint Injection
Venous blood will be drawn from the patient receiving injection treatment. It will be spun down to form PRP and reinjected back into the SI joint. Platelet Rich Plasma Joint Injection: 30 to 50 milliliters of venous blood will be drawn from the patients arm with a 19 gauge ¾ inch needle using universal precautions. The venous blood will be mixed with 8 milliliters of anticoagulant citrate dextrose solution-A (ACD-A). The anti-coagulated blood will then be centrifuged for 15 minutes at 3200 revolutions per minute in the office centrifuge. This will allow plasma to separate from blood cells. The portion of centrifuged blood deficient in platelets will be extracted and discarded. Once the needle is visualized entering the joint capsule via ultrasound guidance and the physician feels resistance provided by the capsule and ligaments, 3 milliliters of PRP extract will be injected (3 inch, 22 gauge needle) into the sacroiliac joint. The needles will be properly disposed.

PRIMARY outcome

Timeframe: Change from baseline compared to 6 months post injection

Standardized questionnaire which asks 10 questions to assess impact on activities of daily living. Minimum score is 0, maximum score is 50. Higher scores mean worse outcome or more impact on function.
