Treatment of Mechanical Low Back Pain With High-Intensity Focused Ultrasound (HIFU)

High-intensity focused ultrasound (HIFU) is an emerging technology that allows for the targeted thermal ablation of deep tissues in a non-invasive manner, by concentrating acoustic energy on the target nerve, whilst preserving adjacent structures. Recently, open clinical studies have confirmed the feasibility, safety and efficacy of HIFU in patients with lumbar facet syndrome, with clinical response rates similar to those of RFA and no significant complications. This observational, prospective, non-interventional study aims to evaluate the clinical efficacy of lumbar medial branch ablation using this technique at 1, 3 and 6 months, as well as to assess patient satisfaction with the procedure. Only clinical data from patients undergoing the procedure in routine clinical practice will be collected.
