Técnica de radiofrecuencia ablativa ecoguiada del nervio sural para el dolor crónico de tobillo. A propósito de un caso

Abstract

Chronic lateral ankle pain related to sural neuralgia is a rare pathology. The sural nerve innervates the sensitivity of the posterolateral border of the leg, as well as the dorsolateral border of the foot. On occasions, sural neuralgia is resistant to conservative treatment and can affect the patient's psycho-emotional and social sphere. We describe the case of a 54-year-old patient with neuropathic pain in the sural territory and a history of several ankle surgeries. After unsuccessful conservative treatment, ultrasound-guided ablative radiofrequency is performed in the sural nerve with subsequent complete cessation of pain without side effects. We propose to give importance to ecopalpation in the consultation of a rehabilitation physician, as well as to describe ultrasound-guided ablative radiofrequency as a safe and effective technique for sural neuralgia that does not respond to conservative treatment. However, more quality studies are needed to corroborate these results.
