Among the 168 studies in Low Back Pain with a site in Spain, from their registry updates:
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.
Patients with mechanical low back pain without any other associated clinical features (neuropathic pain characteristics or significant suspicion of pain in other anatomical regions that may be causing the low back pain) who undergo lumbar medial branch ablation using the HIFU technique.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Pacients with mechanical lumbalgia
Procedure: High-Intensity Focused Ultrasound of the medial lumbar branch
Focal exposure, with a duration of 50 seconds and an energy output of 1000 joules. Monitoring of temperature and the patient's response is essential to avoid collateral damage. The objective is to achieve temperatures of 80-85 °C at the focus to induce thermal necrosis of the nerve.

Start is estimated for Apr 2026; primary completion for Dec 2026, 8 months later.
Of 175 non-industry observational studies under Low Back Pain, half reached primary completion within 24 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 48. This study's planned 8 months is below that.
Counting every sponsor, half of 185 studies reached it within 24 months; a quarter within 10 and three quarters within 48.
