Study summary

Pilot study to evaluate the safety and the effectiveness of the Neurolyser XR as a treatment for sacroiliitis

Read the detailed 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

What researchers measure

Primary outcomes

  1. Effectiveness per pain score using numerical rating scale of 0 to 10

    Pain reduction would be measured using numerical rating scale of 0 to 10 to evaluate pain and brief pain inventory questioner

    Time frame: Baseline throughout the follow-up period of six months

  2. Safety per adverse events

    Measured by the incidence and severity of treatment related adverse events

    Time frame: Baseline throughout the follow-up period of six months

Secondary outcomes

  1. Assess self-rated physical disability caused by low back pain

    Roland-Morris Disability Questionnaire providing a scale of 0 to 24 when 0 is best and 24 is worst

    Time frame: Baseline throughout the follow-up period of six months

  2. Opioid intake dosage using morphine equivalency conversion

    Using by recording patient opioid intake using opioid equivalency chart

    Time frame: Baseline throughout the follow-up period of six months
