MORTON'S NEUROMA

SUMMARY

1. The most common location is between the third and fourth metatarsal heads, leading to referral of pain and paresthesia down the two toes.

2. Patients sometimes describe a sensation of having a pebble in their shoe or a wrinkle in their sock.

3. Pain is exacerbated with forefoot weight-bearing, narrow toe boxes, and high heels, all of which can load the pathologic region.

4. DDx: metatarsalgia.

5. Occasionally there's a click when palpating, especially when combined with squeezing the metatarsal heads together.

6. First-line interventions aim to unload the forefoot, local steroid injection, surgical excision of recalcitrant neuromas.
