This is a new guideline from NICE on treating symptomatic Morton’s neuroma with radiofrequency ablation (RFA). They also list current advised management, which I have added at the bottom, as I felt a bit rusty on it.
RFA is done under LA. A probe is inserted into the webspace and pulses of radiofrequency energy are delivered. This causes thermal ablation of the the nerve. A steroid injection is then given to reduce pain. It can be repeated after a few weeks if needed.
NICE advises that there are no major safety concerns with the treatment, but that there is only limited evidence of its efficacy.
