Morton’s Neuroma: More Than Just Forefoot Pain

Morton’s neuroma — technically an interdigital perineural fibrosis rather than a true tumor — occurs when the common digital nerve in an intermetatarsal space becomes entrapped and undergoes reactive perineural fibrosis from repetitive mechanical compression. The result is a palpable, thickened nerve mass (pseudoneuroma) that produces characteristic burning, electric, cramping, or shooting pain into the affected toes, often described as walking on a pebble or a bunched-up sock.

The 3rd web space between the 3rd and 4th metatarsal heads is affected in 90% of cases — because the nerve supplying this space is larger than elsewhere in the forefoot due to anastomosis between the medial and lateral plantar nerve branches. The 2nd web space is the second most common location. First and fourth web space neuromas exist but are rare and should prompt investigation of other diagnoses.

Why Morton’s Neuroma Develops

Repetitive mechanical compression of the interdigital nerve between metatarsal heads drives perineural fibrosis. The compressive forces come from two directions: transverse compression from tight footwear narrowing the forefoot, and vertical loading during toe-off when metatarsal heads plantar-flex and compress the interspace. Risk factors include pointed toe boxes (narrow forefoot compression), high heels (transfers weight anteriorly and increases metatarsal head loading), hypermobile or splayed forefoot (wider transverse arch loses protective metatarsal compression control), and activities involving repetitive push-off (ballet, running, cycling).

The condition affects women 8–10 times more frequently than men — directly reflecting the difference in typical footwear. This does not mean men don’t get Morton’s neuroma; men in tight work boots, cycling shoes, or ski boots develop it at significant rates.

Diagnosis: Clinical and Ultrasound Confirmation

Clinical diagnosis is confirmed by the Mulder’s click — simultaneously compressing the metatarsal heads medially-laterally (squeezing the forefoot from side to side) while applying dorsoplantar pressure on the affected web space with the opposite thumb. A palpable click and reproduction of the patient’s characteristic pain confirms the diagnosis in approximately 80% of clinical neuromas.

Diagnostic ultrasound is the confirmatory imaging of choice — more accessible and less expensive than MRI, with equivalent diagnostic accuracy for neuromas above 5mm. Ultrasound identifies the characteristic hypoechoic ovoid mass in the plantar interspace below the deep transverse metatarsal ligament. It also guides injection therapy with millimeter precision, ensuring corticosteroid or alcohol is deposited within the neuroma sheath rather than in the overlying web space skin or metatarsal periosteum.

Non-Surgical Treatment: The Evidence Base

Footwear Modification (First-Line)

Wide toe box footwear — sufficient to allow passive toe splay without active shoe pressure — reduces transverse metatarsal compression and is the most important first-line intervention. The shoe must have adequate width at the metatarsal level (not just at the widest point of the toe box). Heels above 2.5cm increase metatarsal head loading and should be avoided or minimized. Many patients with mild neuromas achieve complete symptom control with footwear change alone before any other intervention is required.

Metatarsal Pad Orthotic Modification

A metatarsal pad positioned proximal to the metatarsal heads (behind the heads, not under them) splays the metatarsal heads and expands the interspace, reducing mechanical compression of the interdigital nerve. Integrated into a custom orthotic shell or adhered to an OTC insole as a standalone modification. Clinical studies show metatarsal pad positioning significantly reduces neuroma pain in the majority of mild-moderate cases when combined with appropriate footwear.

Ultrasound-Guided Corticosteroid Injection

Ultrasound-guided corticosteroid injection into the affected interspace — with the needle tip confirmed within the perineural sheath around the neuroma — produces complete or significant symptom relief in 70–80% of patients at 6 months. The key technical element is ultrasound guidance: blind injection into the web space deposits steroid in subcutaneous tissue where it produces skin atrophy and fat pad changes without therapeutic effect on the neuroma. Precise ultrasound-guided delivery concentrates the anti-fibrotic effect at the lesion itself. A series of 2–3 injections spaced 4–6 weeks apart is the standard protocol.

Alcohol Sclerosing Series

Ultrasound-guided injection of 4% dehydrated alcohol into the neuroma — typically a series of 4–7 weekly injections — produces progressive chemical neurolysis and shrinkage of the fibrous neuroma mass. Studies report complete resolution rates of 60–80% with alcohol sclerosing, with durability superior to corticosteroid injection for larger neuromas. A viable alternative to surgery for patients who want to avoid neurectomy or who have failed corticosteroid injection.

Surgical Treatment: Neurectomy

Surgical neurectomy — excision of the affected common digital nerve — produces excellent pain relief in 80–90% of properly selected patients who have failed conservative treatment. The dorsal approach (surgical incision on top of the foot) allows division of the deep transverse metatarsal ligament and removal of the neuroma without the plantar scar that made the older plantar approach problematic for weight-bearing. Patients walk in a surgical shoe immediately post-operatively. Return to normal footwear at 3–4 weeks; full recovery at 6–8 weeks. Permanent numbness in the affected toes is expected and explained pre-operatively.
