About the research
Pilot study to evaluate the safety and the effectiveness of the Neurolyser XR as a treatment for sacroiliitis
Read the full description
Pilot, Interventional, Prospective, Open label, Single Arm study to evaluate Non-invasive thermal ablation of the posterior sacral nerve branches as a treatment of painful sacroiliac joint (SIJ) using High Intensity Focused Ultrasound delivered by the Neurolyser XR.
Patient would be treated and then followed for up to 6 months. Primary safety endpoint will be measured by the incidence and severity of treatment related adverse events Primary effectiveness endpoint will be measured by the changes in average pain score and Rolland Morris Disability Questionnaire between baseline and 6 and 12 months
Who may be able to participate?
The list below is the sponsor’s full registry wording. It can include conditions, prior treatment, test results and other requirements. A match in search does not mean you qualify.
Inclusion Criteria:
1. Adult male and females, legally able and willing to participate in the study and come for follow-up visits
2. Able and willing to fill the research questionnaires and to communicate with investigator and research team
3. Patient with bilateral or unilateral sacroiliac joint pain of \> 6 months duration
4. Patients presenting with a) a positive (\>70% pain relief) to a previous nerve ablation procedure of the sacroiliac joint and / or b) with a positive (\>70% pain relief) to a previous nerve block procedure of the sacroiliac joint within the last six months)
5. Average pain score of 4 or higher in the last month, (on 0-10 scale).
Exclusion Criteria:
1. Pregnant or breastfeeding patient
2. Patients younger than 18 or older than 80 years
3. Patients presenting with neurological deficits (including lumbosacral radiculopathy but not solitary radicular pain).
4. Patients with history of lumbar and / or sacral spine surgery
5. Patients with the presence of metal hardware at the lumbosacral spine
6. Patients with history of pelvic pathology that may increase procedural risk and / or influence symptoms and / or generate unrelated adverse event (per the discretion of the study PI)
7. Patients unable to understand and complete the research questionnaires in Hebrew.
8. Patients presenting with any severe medical condition preventing the patient from safely and effectively being treated in the study or reporting study outcome.
9. Patient with extensive scarring in the skin and tissue overlying the treatment area.
10. Patients enrolled in or planned to be enrolled in another clinical trial during the duration of this research project
Treatment, groups and participation
The registry may describe treatments and study duration without a complete visit calendar. Ask the study team for the exact schedule, procedures, risks, costs and alternatives. Keep your usual care plan unless your treating clinician tells you otherwise.

What researchers are measuring
Outcome measures describe what is being studied. They are not proof that a treatment works.
Primary measures
Effectiveness per pain score using numerical rating scale of 0 to 10
Time frame: Baseline throughout the follow-up period of six months
Pain reduction would be measured using numerical rating scale of 0 to 10 to evaluate pain and brief pain inventory questioner
Safety per adverse events
Time frame: Baseline throughout the follow-up period of six months
Measured by the incidence and severity of treatment related adverse events
Secondary measures
Assess self-rated physical disability caused by low back pain
Time frame: Baseline throughout the follow-up period of six months
Roland-Morris Disability Questionnaire providing a scale of 0 to 24 when 0 is best and 24 is worst
Opioid intake dosage using morphine equivalency conversion
Time frame: Baseline throughout the follow-up period of six months
Using by recording patient opioid intake using opioid equivalency chart
