The L4-L5 and/or L5-S1 facet joint can be included in the ablation per doctor discretion.~* Correct spinal levels (ranging L4-S3) to be treated have been confirmed by 1) diagnostic SIJ injection, followed by 2) diagnostic Medial/Lateral Branch Block at the applicable levels.~* The subject is likely to follow standard of care post-operative follow-up for at least 24 months.~Exclusion Criteria:~Patients receiving additional invasive back surgery after the study treatment.~* Inability to complete follow-up visits or required questionnaires.~* Non-compliant patients~* Difficult or impossible communication with the patient~* Breastfeeding, pregnant or patients who plan a pregnancy while participating in the study~* Systemic neurological disorders with mobility limitations (e.g. advanced Parkinson's disease or multiple sclerosis)~* Patients with incompatibilities or known limitations that make participation impossible~* Patients after stabilization with implants on thoracic or lumbar spine.~* Inability to provide informed consent without a legally authorized representative.

Study Arms:
- Treatment: Endoscopic ET on SI joint (Type: EXPERIMENTAL): New techniques have been developed and tested to expand the usefulness of minimally invasive spine surgery beyond disk herniation. This includes endoscopic electrothermic ablation which can be used to target SIJ-associated CLBP. A small retrospective study demonstrated significant improvements in Visual Analog Scale and Oswestry Disability Index from pre-operative levels in patients with CLBP associated with the SIJ for up to 21 months following the procedure. However, there has not yet been a prospective study to assess the efficacy of this procedure, and therefore, this is the aim of this study.

Based on this trial design, predict the completion outcome and termination type (if applicable).
