A dropped metatarsal is one of those structural foot problems that causes years of mystery pain before getting a proper diagnosis. Patients come into Balance Foot & Ankle with persistent callus and ball-of-foot pain under one specific metatarsal, having tried insoles, padding, professional callus removal, and everything else they can find. When Dr. Tom Biernacki does a standing examination and weight-bearing X-ray, the answer is often immediately clear: one metatarsal is sitting 3–5mm lower than its neighbors, and every step concentrates the entire body’s propulsive force at that single point. Once you see it, you can’t unsee it — and once you address it, patients often get relief they haven’t had in years.

What Is a Dropped (Plantarflexed) Metatarsal

In a normal forefoot, the five metatarsal heads form a smooth parabolic arc from the first (medial) to the fifth (lateral), with the load distributed relatively evenly across the transverse metatarsal arch during the push-off phase of gait. When one metatarsal — most commonly the second or third — is “dropped” (plantarflexed, meaning angled downward relative to its neighbors), its head protrudes below the arc and bears disproportionate load.

The medical term is plantarflexed metatarsal or long metatarsal syndrome when the drop is due to relative length discrepancy. The practical result is the same: one metatarsal head takes 2–4× the normal ground reaction force it should bear, producing a painful intractable plantar keratosis (IPK) — a dense, focally nucleated callus directly under the affected metatarsal head.

Causes and Risk Factors

Structural (congenital/developmental): The most common cause — some individuals simply develop a metatarsal formula (relative metatarsal lengths) that creates a prominent second or third metatarsal head. An “index minus” foot (second metatarsal longer than first) has inherent second metatarsal overloading even without true plantarflexion.

Post-surgical: Bunion surgery that shortens or elevates the first metatarsal (particularly older osteotomy techniques) transfers load to the second metatarsal, producing a “transfer lesion” — a painful callus under the second metatarsal head that develops 6–18 months after bunion surgery. This is a known complication of first metatarsal shortening osteotomies and highlights why metatarsal parabola restoration is critical in surgical planning.

First ray hypermobility: When the first metatarsal is excessively mobile (hypermobile first ray), it fails to bear its share of propulsive force, transferring load to the second metatarsal. This is commonly associated with flatfoot deformity and bunions — the hypermobile first ray is both a driver of bunion formation and a cause of second metatarsal overloading.

Lesser toe deformities: Hammertoes and mallet toes cause the proximal phalanges to extend at the MTP joints, which actually increases plantarflexory force on the metatarsal head. The “knuckling up” of the toe retroactively depresses the metatarsal head, worsening the drop.

Neuromuscular conditions: Cavus foot deformity (from CMT disease, Friedreich’s ataxia, or idiopathic high arch) is associated with anterior cavus where the metatarsals are plantarflexed, producing diffuse but concentrated forefoot loading. Any condition causing intrinsic muscle wasting (diabetes, peripheral neuropathy) destabilizes the transverse metatarsal arch.

Symptoms and Diagnosis

Symptoms: Focal burning, aching, or sharp pain under one specific metatarsal head, exactly where the callus is located. Pain that is dramatically worse barefoot or in thin-soled shoes and improved with thick-cushioned footwear. A hard, dense callus under the metatarsal head — distinguishable from a plantar wart by its smooth, glassy surface without the dark “seed” hemorrhages of warts. Pain worsens with prolonged standing, walking, or any forefoot loading activity.

Clinical examination: The “callus test” — the location of the callus precisely predicts the overloaded metatarsal. Press directly on the callus and reproduce the pain; this confirms the metatarsal as the culprit. Observe the foot from below (plantar view) in weight-bearing — a prominent metatarsal head is often visible as a discrete depression in the fat pad overlying it.

Imaging: Weight-bearing AP and lateral X-rays are essential. The lateral view shows the relative plantarflexion of the dropped metatarsal. A “Meary’s angle” measurement and metatarsal parabola analysis from the AP view confirm length and position discrepancy. CT scan provides three-dimensional assessment when surgical planning is needed.

Differentials to exclude: Intractable plantar keratosis must be distinguished from: plantar wart (verruca — has HPV-associated hemorrhagic punctae and disrupts skin lines), Morton neuroma (pain between metatarsal heads, not directly under them), plantar fibromatosis (palpable nodule in the arch, not under a specific metatarsal head), and diabetic neuropathic ulcer (skin breakdown in a neuropathic patient).

Why Dropped Metatarsals Cause Painful Callus: The Mechanics

The plantar fat pad under the metatarsal heads normally cushions and distributes ground reaction forces. But when one metatarsal consistently bears 2–4× the normal force, the fat pad migrates distally (forward) away from the overloaded head over time — a process called “fat pad migration” or “fat pad atrophy.” Without this protective cushion, the skin over the metatarsal head is subjected to direct shear and compression with every step.

The body responds by thickening the skin — creating a callus (keratoma) — but this response is self-defeating: the callus itself becomes a focal hard prominence that concentrates force even further, worsening the pain cycle. In severe cases, a nucleated callus (IPK — intractable plantar keratosis) develops with a central hard core that feels like “stepping on a stone with every step,” as patients often describe it.

Conservative Treatment for Dropped Metatarsal

Metatarsal pad placement (most important first step): A metatarsal pad — placed PROXIMAL to the dropped metatarsal head (not under it) — redistributes load from the dropped metatarsal head to the adjacent metatarsal shafts. Correct placement is critical: the pad must be positioned 5–10mm proximal to the metatarsal head to create a raised platform that shifts load forward. A pad placed directly under the callus worsens pain. This is the most common error we see with self-applied metatarsal padding.

Custom orthotics with intrinsic metatarsal accommodation: A custom orthotic allows precise metatarsal pad positioning and can add a first ray cut-out to encourage first metatarsal load-bearing (addressing first ray hypermobility simultaneously). Off-the-shelf options like PowerStep Pinnacle Maxx with an added metatarsal pad provide a cost-effective starting point. CURREX RunPro insoles have good forefoot cushioning for athletic use during recovery.

Callus debridement: Professional callus debridement by a podiatrist (sharp debridement of the callus with a scalpel) provides immediate but temporary relief. The callus will recur within 4–8 weeks unless the underlying mechanical overloading is addressed. Debridement combined with offloading orthotic management is dramatically more effective than either alone.

Footwear modification: Shoes with a wide, deep toe box and a stiff, rocker sole reduce peak pressure under the metatarsal heads by 30–40%. High heels are absolutely contraindicated — they shift body weight directly onto the metatarsal heads, dramatically worsening dropped metatarsal pain. HOKA and New Balance wide-width running shoes are excellent options for patients dealing with dropped metatarsal loading.

Doctor Hoy’s Natural Pain Relief Gel applied to the plantar forefoot after activity provides topical anti-inflammatory relief without systemic NSAID side effects — useful during the acute pain phase before orthotics are fabricated.

Surgical Treatment: Dorsiflexory Metatarsal Osteotomy

When conservative management fails to provide adequate pain relief after 3–6 months — or when the structural deformity is severe enough that orthotics cannot compensate — surgical elevation of the dropped metatarsal (dorsiflexory wedge osteotomy) is indicated.

The procedure: A dorsiflexory wedge osteotomy removes a small wedge of bone from the metatarsal neck or shaft, angulating the distal fragment upward (dorsally) to elevate the metatarsal head. The fragment is stabilized with a small plate, screw, or K-wire while healing. The goal is to restore the metatarsal head to the parabolic arc of its neighbors — not to overcorrect, which would transfer the lesion to an adjacent metatarsal.

Recovery: 4–6 weeks in a surgical shoe or boot with protected weight-bearing, followed by gradual return to normal footwear as healing is confirmed on X-ray. Complete resolution of the callus takes 3–6 months as the pressure is eliminated and the skin normalizes. Success rates of 85–95% in appropriately selected patients when correction is precise.

Key surgical principle: Always plan the parabola. Isolating one metatarsal osteotomy without considering the relative lengths and positions of all five metatarsals risks creating a transfer lesion. In our practice, we assess the full metatarsal parabola on weight-bearing X-rays before any forefoot osteotomy and adjust the planned correction accordingly.

Frequently Asked Questions

What is a dropped metatarsal?

A dropped (plantarflexed) metatarsal is a structural condition where one metatarsal head sits lower than its neighbors in the forefoot, bearing disproportionate weight-bearing load. This creates focal overloading, a painful nucleated callus (intractable plantar keratosis) directly under the affected metatarsal head, and metatarsalgia with every step. Treatment ranges from metatarsal pad orthotics to surgical osteotomy depending on severity.

What is the best way to treat a dropped metatarsal without surgery?

The most effective non-surgical treatment is correct metatarsal pad placement — positioned 5–10mm proximal (behind) the dropped metatarsal head, not under it. This redistributes load from the prominent head to the metatarsal shafts. Combined with custom orthotics, wide-toe-box cushioned footwear, and professional callus debridement, most mild-to-moderate cases achieve significant pain reduction. Eliminating high heels is mandatory.

What does a dropped metatarsal feel like?

A dropped metatarsal produces burning, aching, or sharp pain directly under one specific metatarsal head — exactly where a hard callus forms. Many patients describe it as “walking on a pebble” or a “stone bruise” that never goes away. Pain is significantly worse barefoot or in thin-soled shoes, worse with prolonged standing or walking, and temporarily relieved by removing the shoe and massaging the forefoot.

When should I see a podiatrist for a dropped metatarsal?

See a podiatrist when ball-of-foot pain under a specific metatarsal head persists despite cushioned footwear, when a recurrent callus forms under the same spot every 4–8 weeks, when the pain is limiting your daily activities, or if you are diabetic and have any focal plantar callus (pre-ulcerative risk). Dropped metatarsal is easily confirmed with weight-bearing X-rays and highly treatable when addressed early.

Does insurance cover dropped metatarsal treatment?

Yes — podiatric evaluation, X-rays, and custom orthotics for dropped metatarsal are covered by most insurance plans when medically necessary. Professional callus debridement is covered as a medically necessary procedure. Surgical osteotomy is covered after documented failure of conservative care.
