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.
