Ultrasound-Guided Thermocoagulation of Medial Nerve Branch in Lumbar Facet Joints Pain.

We propose here to evaluate the precision of lumbar thermocoagulation performed under a transverse ultrasound approach by performing a fluoroscopic control once the needle in the desired position. The effectiveness of the technique will be assessed by measuring different pain and disability scores at six weeks post-thermocoagulation: the Visual analogue pain Scale score (VAS) and the Oswestry disability score (ODI) will be collected, compared to that of the conventional fluoroscopic technique.
