Abstract

Neuropathic pain can be treated with peripheral nerve stimulation (PNS), a technique that has become more widespread following the introduction of ultrasound-guided placement. Superficial radial nerve neuropathy is a common disorder, and implanting a PNS device in the distal humeral has been shown to provide good pain control; however, the nerve block test is negative is some patients, and are therefore not candidates for neurostimulation. We report a case of ultrasound-guided implantation of a peripheral nerve stimulator in the spiral groove to treat superficial radial nerve neuropathy. The treatment provided good pain control for more than 1 year, at which time the electrode lead fractured and had to be surgically removed and reimplanted. This may be an effective alternative in certain patients, although further studies are required.

Resumen

Los neuroestimuladores periféricos se pueden emplear para el tratamiento del dolor neuropático, y su uso ha aumentado al emplearse la ecografía para su colocación. La neuropatía del nervio radial superficial es frecuente y se han descrito implantes a nivel humeral distal con adecuado control del dolor, pero no todos los pacientes presentan un bloqueo test positivo en este lugar, necesario para su implante. Presentamos un caso de implante ecoguiado de neuroestimulador periférico en el canal de torsión radial como tratamiento de una neuropatía del nervio radial superficial con adecuado control del dolor durante más de un año, aunque tras ese tiempo el electrodo sufrió una fractura y tuvo que retirarse y reimplantarse de forma quirúrgica. Este enfoque puede ser una alternativa eficaz en pacientes seleccionados aunque se requieren más estudios.
