Morton neuroma is a painful condition affecting the common plantar digital nerve, most frequently in the third web space (between the third and fourth metatarsals), less commonly in the second web space. It is not a true neuroma (tumour of nerve tissue) but a perineural fibrosis -- a thickening and scarring of the tissue surrounding the nerve, caused by repetitive compression between the metatarsal heads. It produces a characteristic electric-shock or pebble-in-shoe sensation in the forefoot, triggered by weight-bearing and narrow footwear.
How Morton Neuroma Affects Walking
The peak pain in Morton neuroma occurs during the push-off phase of gait: at toe-off, the forefoot is under maximum load and the metatarsal heads compress the interdigital spaces, directly compressing the entrapped nerve. High-heeled shoes and narrow toe boxes worsen this compression; barefoot walking on sand or grass is often relatively comfortable (wider toe box equivalent).
Cane Use in Morton Neuroma
A walking cane reduces overall forefoot loading by providing an additional weight-bearing surface through the upper limb. The greatest benefit is during toe-off: the cane contacts the ground opposite the affected foot at the moment of peak forefoot compression, partially substituting for the push-off force and reducing metatarsal head compression. This is similar to the mechanism by which a cane helps in metatarsalgia generally.
Morton Neuroma Severity and Cane Role
| Severity | Symptoms | Cane Role |
|---|---|---|
| Mild | Occasional pain; related to specific footwear | Cane rarely needed; footwear change primary |
| Moderate | Regular pain with walking; electric-shock sensations | Cane optional; reduces forefoot loading; useful for long distances |
| Severe / chronic | Constant pain; cannot weight-bear comfortably; quality of life impaired | Cane beneficial; reduces push-off forefoot load; combine with metatarsal pad and wide footwear |
| Post-injection or post-surgical | Recovery from steroid injection or surgical excision | Cane for 1-3 days post-injection; 2-4 weeks post-surgical |
Metatarsal Pad and the Cane: Additive Strategy
A metatarsal pad placed just proximal to the metatarsal heads redistributes forefoot load from the metatarsal heads to the shaft of the metatarsals, directly reducing interdigital space compression. A cane reduces total forefoot load. Used together, the pad distributes load more safely within the foot, and the cane reduces the total load delivered to the foot: additive strategies for forefoot pain reduction. This combination is often effective enough to avoid surgery in moderate Morton neuroma.
