Purpose Morton’s neuroma (MN) is a leading cause of
disability. The purpose of this study was to investigate the
effectiveness of radiofrequency (RF) in patients with
chronic pain refractory to conservative therapies.
Methods Between September 2012 and December 2016,
RF was performed on 52 patients. A sterile RF needle
probe (22G, 5-cm needle with 10-mm electrode active tip)
was inserted between the toes into the intermetatarsal space
at the center of the lesion. Potential complications of the
intervention and post-procedure care were examined. All
patients provided written, informed consent. All percuta-
neous procedures were performed with the NeuroTherm 
NT1100 (Neurotherm Inc., M.) device and using ultrasound
guidance (Philips IU22). Continuous RF was performed
with one cycle of 90 s and with the probe tip maintaining a
temperature of 85 C (impedance 95–210 mX).
Results Mean VAS score before the procedures was
9.0 ± 0.6. A reduction of pain intensity was achieved after
1 week by RF (mean VAS scores 3.7 ± 0.9; p \ 0.05),v
