The sacroiliac (SI) joint is a common source of low back pain. Radiofrequency ablation (RFA) can be used to treat low back pain from the SI joint , and is often recommended by physicians to provide long lasting pain relief. However, the use of RFA for SI joint pain has not been as successful as RFA for pain in other areas of the back and neck. X-ray guidance (fluoroscopy) is currently used to perform this procedure. Under fluoroscopy, however, it can be difficult for physicians to identify necessary landmarks, and there are risks to the patient because of radiation exposure. In contrast, ultrasound may provide better image guidance than fluoroscopy, and there is no radiation risk. The purpose of this study is to examine if ultrasound guided SI joint RFA is effective.

Eligibility |
Inclusion Criteria: - 18 years of age or older - Clinical presentation compatible with SI joint origin pain (back pain below L5; localized to the SI joint area; >2 positive of 5 SI joint provocative tests). - >50% index pain relief with at least one SIJ intra-articular local anesthetic block and at least one SIJ lateral branch block using the conventional fluoroscopically guided lateral branch block technique. Pain diary records for these interventions need to be on file. Exclusion Criteria: - Under 18 years of age - Presence of clinical and investigative evidence of inflammatory spondyloarthropathy, fibromyalgia, radiculopathy, symptomatic spinal stenosis, facetogenic or discogenic low back pain, generalized infection, localized infection in the area of the low back/SIJs, coagulopathy or anticoagulation, allergy to local anesthetic |

Primary | Numeric rating scale for pain | Pain diary scores for first 6 hours post-block | Hourly for 6 hours post-block | |
Primary | Pain Disability Quality-of-Life Questionnaire (PDQQ-S) | The PDQQ-S is a 6 item questionnaire exploring 3 domains: pain, disability and quality-of-life. There are 2 questions for each domain and each is graded from 0 to 10 using a numerical rating scale. Ultrasound-guided SIJ RFA results will be compared to previous fluoroscopic-guided SIJ RFA results at 2 months. | 2 months post-RF procedure | |
Secondary | Pain Disability Quality-of-Life Questionnaire (PDQQ-S) | Secondary outcome will be the duration of improvement on the PDQQ-S, and will be measured by repeat administration of the PDQQ-S every 3-4 months up to 24 months post-procedure. If there is ongoing, clinically significant relief at 6 months (>30% improvement in pain intensity and/or at least 2 point improvement on the pain severity question (question #1) of the PDQQ-S), patients will be reached by phone to complete the PDQQ-S at 3-month intervals up to 12 months post-RFA and then at 4-month intervals up to 24 months, or until their pain intensity returns to baseline (<30% improvement and/or <2 point improvement on question 1 of the PDQQ-S on 2 consecutive follow-ups), whichever comes first. | 6, 9, 12, 16, 20 and 24 months post-RF procedure |
