Superior cluneal nerves radiofrequency in the management of chronic low back pain.

Introduction: Chronic low back pain is a highly prevalent condition with multiple etiologies. Cluneal nerve neuropathy is an increasingly relevant condition in the management of this condition, and radiofrequency is an alternative management option.

Methods: A case series, which included four patients who underwent ultrasound-guided conventional radiofrequency intervention of the superior cluneal nerves, using a previously undescribed technique and direction of intervention.

Results: Patients reported a 50-90 % improvement in pain and a functional benefit for their daily activities of more than 40 % at 4- and 10-week follow-up, with no adverse events following the intervention.

Conclusions: Continuous radiofrequency of the cluneal nerves is an interesting alternative in the management of this pathology of low back pain. The ultrasound technique described may be a management proposal with lower risk and adequate effectiveness.
