About this study
Official title: Effectiveness of Ultrasound Guided Platelet Rich Plasma Injections in the Sacroiliac Joint to Relieve Low Back Pain
This prospective study will be quantitatively analyzing the effectiveness of platelet-rich-plasma (PRP) injections into the sacroiliac (SI) joint in relieving sacroiliitis and low back pain originating from the SI joint. The effectiveness of PRP injections on joint pain has been well studied in the knee and shoulder. PRP injections are performed on the SI joint commonly, but there is little research documenting their effectiveness when compared to other interventions. This study will be a small pilot study to aid in closing this knowledge gap. Additionally, these injections will be performed under ultrasound guidance. Ultrasound has been proven to be of equal reliability to fluoroscopy and has the advantage of shorter time to administer and no radiation. There will be one arm to this study. The data collected will be compared to existing studies on corticosteroid SI joint injection. The experimental arm consists of the PRP injection. The PRP will be injected into the joint using the exact same technique via physical exam, special tests, and ultrasound guidance as performed in our previous studies. The outcomes will be measured with the Numeric Rating Scale for Pain (NRS) and the Oswestry Disability Index (ODI) prior to the injection, immediately post-injection, 2 weeks, 4 weeks, 3 months, and 6 months post-injection. The investigators hypothesis is, "Platelet-Rich Plasma Injections in the Sacroiliac Joint using ultrasonography in conjunction with physical examination and Point of Maximal Tenderness will produce statistically significant pain relief for more than 3 months as measured by the Numeric Rating Scale for Pain (NRS) and Oswestry Disability Index (ODI)."
Read the detailed description
PRP is not just an additional tool for physicians to use, but a potential treatment for underlying joint pathology. PRP is one of the closest treatments that exists for a definitive solution for inflammatory and degenerative joint disease. PRP is currently being used for dysfunction of the shoulder joint, knee joint, sacroiliac joint, facet joints, intervertebral discs, rotator cuff, hamstrings, and others. It has been extensively researched for osteoarthritis, tendon, and ligament injury of the knee, but little research has documented the short or long-term effects on the sacroiliac joint. A brief search on PubMed provides only two articles, one of which is a case study, and neither were performed in the United States. PRP is the future of orthopedics and physical medicine as well as a gateway to curing degenerative and inflammatory joint disease.
Furthermore, the use of ultrasound guided injections has helped increase the success rate because it provides a method for visualizing the path of the needle to a precise location. In recent studies, authors have indicated the use of a curvilinear transducer to be the most successful, as well as injections administered to the lower one third of the sacroiliac joint, to be adequately effective in diagnosing and treating sacroiliac joint pain. Disadvantages surrounding fluoroscopy include inconvenience, cost, radiation, and exposure to contrast media. Arranging the procedure can take extensive time and resources. The procedure can be costly for the patient, especially if it does not produce long-term results, and radiation exposure can have long-term consequences for the patient's health, rendering it a questionable treatment for chronic low back pain. As ultrasound guided and fluoroscopic sacroiliac joint injections present themselves as front-runners for diagnosis and treatment of sacroiliac joint-induced low back pain, the benefits and downsides to both are heavily weighed and compared. The next step moving forward in the treatment of the SI joint is administering PRP injections while utilizing ultrasonography for image guidance. The investigators believe this combination will provide the most immediate and long term benefit to patients as well as fewer risks from medications, corticosteroids, and fewer risks and downsides from fluoroscopy, such as radiation and cost.
Experimental design will be a nonrandomized trial (or quasi-experiment). The specific study design to be used is pretest-posttest design. The independent variable will be the PRP injection. The dependent variables of interest include the NRS and Oswestry Disability Index (ODI) recording pre-injection, immediately post-injection, 2 weeks, 4 weeks, 3 months, 6 months post-injection.
Most studies in the past look at short-term and moderate-term results up to approximately six months to one year. Many studies state a limitation to their data is the lack of long-term investigation into pain, disability, and function more than 12 months. This is partly due to losing patients to follow up. Patients whose pain resolved have no reason to return for further evaluation.
The investigators will take measures to avoid study bias and confounding by ensuring patients have been correctly diagnosed with sacroiliitis via special tests and physical examination as well as PMT. Additionally, to avoid confounding, the investigators will not administer PRP injections to patients who have had a corticosteroid injection in the SI joint within the last three months or received significant benefit from a corticosteroid injection. The efficacy of corticosteroids in the joint begin to dwindle starting at approximately three months.
This information will be recorded in each patient's chart as well as an Excel file only accessible to key personnel working on the study. The following data will be recorded form each patient: current pain scale using the NRS and their functionality using the ODI.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Platelet Rich Plasma Joint InjectionDrug
Also called PRP Joint Injection, PRP
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.
| Study group | Role | What they receive |

| Platelet Rich Plasma Joint Injection | Experimental | 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. Receives: Drug: Platelet Rich Plasma Joint Injection |
What is being measured
The primary outcome is the main question the study is designed to answer.
Numeric Rating Scale for Pain (NRS)
Defined as a numeric scale for pain from 0 to 10. 0 demonstrates no pain and 10 demonstrates severe pain or significant impact on activities of daily living.
Measured: Change from baseline compared to 6 months post injection
Oswestry Disability Index (ODI)
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.
Measured: Change from baseline compared to 6 months post injection
