Morton’s Toe vs. Morton’s Neuroma — Two Different Conditions

Morton’s toe and Morton’s neuroma share the name but are entirely different conditions causing different types of foot pain. Morton’s toe is an anatomical variant — the second toe is longer than the first (hallux), or the first metatarsal is shorter than the second metatarsal, shifting weight-bearing load to the second metatarsal head. Morton’s neuroma is a perineural fibrosis (thickening of the nerve sheath) of the common digital nerve as it passes between the third and fourth metatarsal heads, causing burning, electrical, or sharp pain in the third-fourth toe web space. Correctly distinguishing these conditions is essential because the treatment is completely different. At Balance Foot & Ankle in Howell and Bloomfield Hills, Michigan, Dr. Tom Biernacki, DPM evaluates both conditions. Call (810) 206-1402.

Morton’s Toe — Anatomy, Biomechanics, and Problems It Causes

Morton’s toe (long second toe or short first metatarsal) is present in approximately 20–25% of the population. In most people it causes no symptoms. When symptomatic, it causes: second metatarsal stress fractures (the second metatarsal bears disproportionate weight because the first metatarsal is short and cannot share load normally); second metatarsophalangeal joint (MTP) capsulitis — the joint capsule becomes inflamed from repetitive overloading, causing second toe pain, swelling, and eventual “crossover toe” deformity where the second toe drifts upward and over the hallux; and hallux valgus (bunion) progression — the undersupported first ray allows the hallux to drift laterally. Pain from Morton’s toe is located at the second MTP joint, not the interdigital space.

Morton’s Neuroma — Anatomy, Symptoms, and Diagnosis

Morton’s neuroma is perineural fibrosis at the common digital nerve in the third-fourth intermetatarsal space (occasionally second-third). The nerve is compressed between the metatarsal heads during walking, particularly in narrow shoes. Symptoms: burning, electrical, sharp, or cramping pain at the ball of the foot between the third and fourth toes; sensation of “stepping on a pebble”; and pain relieved by removing the shoe and rubbing the foot. The Mulder click test (squeezing the forefoot medial-laterally while palpating the intermetatarsal space) reproduces or eliminates a click with pain — high specificity for Morton’s neuroma. Diagnostic ultrasound demonstrates the hypoechoic nerve thickening between the metatarsal heads with high sensitivity.

Treatment for Morton’s Toe

Morton’s toe management: custom orthotics with a Morton’s extension (a first-ray extension that elevates the first metatarsal to share load with the second) — the most effective conservative intervention; metatarsal pad placed just proximal to the second metatarsal head to reduce peak pressure; and wide toe box footwear to prevent lateral compression. For second MTP capsulitis, ultrasound-guided cortisone injection reduces acute capsular inflammation. For crossover toe deformity — second MTP plantar plate repair is the surgical option when conservative management fails.

Treatment for Morton’s Neuroma

Morton’s neuroma management: wide toe box footwear that eliminates intermetatarsal compression; metatarsal pad proximal to the affected space to splay the metatarsal heads; and ultrasound-guided corticosteroid injection into the affected interspace — provides 3–6 months relief in 60–70% of patients. Alcohol sclerosing injections (4–7% alcohol solution) are an alternative that chemically desensitizes the nerve — requires 3–7 injection sessions. Surgical neurectomy (excision of the neuroma) for failed conservative management provides 80–90% relief but creates permanent numbness in the third-fourth toe web space. Radiofrequency ablation is an emerging minimally invasive alternative to excision.
