INTRODUCTION AND IMPORTANCE

Morton's Neuroma is a neuropathy of the forefoot, specifically located on the interdigital nerve, and is associated with the thickening of the intermetatarsal ligament and nerve fibrotic. The management of Morton's Neuroma is challenging. Various treatments have been introduced for treating this lesion, starting from conservative treatment using the metatarsal pad, physical therapy, and corticosteroid injection to surgical treatment. This report highlights a novel approach to Morton's Neuroma using a pulsed radiofrequency (PRF).

CASE PRESENTATION

A 53-year-old female, working as a tailor, was transferred to the orthopedic clinic after complaining of pain in her right plantar surface, and she was restricted from standing, walking, and descending stairs. The patient was administered analgesics and anti-inflammatory drugs, but the pain worsened. In the physical examination, there are no signs of trauma on the right foot. There was tenderness in the 2nd and 3rd metatarsal space, and increasing pain was obvious when the foot was squeezed. Magnetic Resonance Imaging (MRI) represents Neuroma in the intermetatarsal II-III segment. After a thorough examination, the patient was diagnosed with Morton Neuroma.

CLINICAL DISCUSSION

We performed a pulsed radio frequency (PRF) with linear Ultrasonography (USG) guidance from the plantar of the foot. PRF delivers in two cycles, each lasting 4 min. The patient was followed for six months. The Visual Analog Scale (VAS) and Foot and Ankle Disability Index (FADI) score were used to evaluate the patient's outcome.

CONCLUSION

A PRF approach is a favorable option for treating Morton's neuroma patients. VAS and FADI scores represent good functional outcomes.
