Hammer Toe: Causes & Treatment 2026 | Podiatrist

If your second toe has slowly bent into an upside-down V and your shoe rubs a corn on top of it, you have what podiatrists call a hammertoe. In our clinic, we see this every single day, and the question patients are really asking is the right one: is this going to need surgery, or can we still fix it without? The honest answer depends on whether your toe is still flexible or has stiffened into a rigid contracture — a difference you and your podiatrist can confirm in 30 seconds in the office. This guide walks through the whole decision tree, with the same words and tests we use at the bedside.

What a hammertoe is (and what it isn’t)

A hammertoe is a deformity in which the proximal interphalangeal joint (PIPJ) of a lesser toe — most commonly the second — is bent downward into flexion while the metatarsophalangeal joint (MTPJ) at the base of the toe is extended upward. The result is a toe that buckles into an upside-down V, with the knuckle (PIPJ) sitting high enough to rub on the top of every shoe. Over time, that rubbing creates a dorsal corn, while the tip of the toe punches downward and forms a second corn or callus underneath.

Hammertoe is a category, not a single disease. It is one of three closely related lesser-toe deformities — hammer, claw, and mallet — that differ only in which joints are contracted. Telling them apart matters, because the surgical correction is joint-specific. We will take the differential apart in detail below.

Flexible vs rigid: the decisive distinction

The most important question in any hammertoe evaluation is whether the deformity is flexible or rigid. A flexible hammertoe can be passively straightened by your podiatrist’s fingertip, and the joint cartilage and capsule are still healthy. A rigid hammertoe resists passive correction; the soft tissues have shortened and contracted, and joint surfaces have begun to remodel. The two require different treatment paths, and confusing them is the most common reason a hammertoe surgery delivers a disappointing result.

The bedside test is simple. Sit you down, hold the metatarsal head still with one hand, and try to push the bent toe down flat with the other. If it goes flat with mild pressure and rebounds when released, it is flexible. If it stays bent or only partially corrects, it is rigid. We also check the Kelikian push-up test: pushing up under the metatarsal head from below mimics weight-bearing — a flexible toe straightens with that maneuver, a rigid one does not.

Causes and risk factors

Hammertoe causes break down into three families: footwear, biomechanics, and disease. The mechanism in every case is the same — an imbalance between the long extensor tendon (which tries to pull the toe up at the base) and the long and short flexor tendons (which pull the toe down at the joints) — but the trigger varies by patient. Most of the patients we see have more than one of the following.

• Tight, narrow, or pointed shoes — the leading cause in adult women; chronic crowding forces the toe into flexion until the contracture becomes permanent.
• Bunion deformity — a hallux valgus pushes the great toe under or over the second toe, displacing it and accelerating PIPJ contracture.
• Long second toe (Morton’s foot type) — a relatively long second metatarsal or phalanx is biomechanically predisposed to buckle in a normal-length shoe.
• Plantar plate tear/MTPJ instability — loss of the plantar restraint at the second MTPJ is a frequent partner of hammertoe in adults >40.
• Diabetic neuropathy — intrinsic muscle wasting plus sensation loss accelerates contracture; high amputation risk if a corn ulcerates.
• Rheumatoid arthritis — synovitis erodes the MTPJ, drives subluxation, produces classic claw and hammer combinations.
• Prior trauma — old fractures or capsular injuries.
• Charcot-Marie-Tooth and other peripheral neuropathies — intrinsic-extrinsic muscle imbalance produces the high-arched cavus foot with bilateral hammertoes.
• Stroke or upper-motor-neuron disease — spasticity through the long flexors.
• Aging — loss of intrinsic muscle bulk over decades.

Symptoms and the corn-callus pattern

Hammertoe symptoms follow a pattern that lets you almost diagnose it from the corn map alone. The dorsal corn over the PIPJ tells you the joint is hitting the top of the shoe. The corn or callus at the tip of the toe tells you the toe is jamming straight down into the insole. The callus under the metatarsal head tells you the MTPJ is hyperextended and the metatarsal head has dropped — a sign of plantar plate dysfunction. Pain is not always present early; it usually arrives once the corns thicken or the MTPJ starts to subluxate.

• Dorsal corn (heloma durum) over the PIPJ knuckle, painful in shoes
• Distal corn or callus at the tip of the toe (rigid hammers especially)
• Plantar callus under the involved metatarsal head, often with diffuse forefoot ache
• Visible bend in the toe at the PIPJ — obvious to the patient out of the shoe
• Pain with push-off, especially in heels or hard-soled dress shoes
• Toe crossing or floating — second toe drifting medially over the great toe is a sign of advanced plantar plate tear
• A “walking on a marble” sensation in the ball of the foot when the metatarsal head displaces

Differential diagnosis: hammertoe vs claw vs mallet vs turf toe

The lesser-toe deformity differential matters because the surgical fix is joint-specific. A hammertoe is a PIPJ flexion problem. A mallet toe is a DIPJ flexion problem. A claw toe is a hammer plus a hyperextended MTPJ — usually neuromuscular and usually bilateral. Plantar plate tear and turf toe both involve the MTPJ but originate at the joint capsule and present differently. Use the table below to keep them straight.

Diagnosis — the office exam

Hammertoe diagnosis is clinical — we make it on inspection and a 30-second physical exam. Imaging confirms severity, rules out arthritis, and plans surgery, but it does not change the diagnosis. The visit takes about 20 minutes start to finish in our office.

• Inspection. Out of the shoe, weight bearing if possible. Identify the deformed joint, count the toes involved, and find the corns and calluses.
• Flexible vs rigid test. Hold the metatarsal still and push the bent toe straight. Note resistance.
• Kelikian push-up. Push up under the metatarsal head; a flexible toe straightens.
• Drawer test (MTPJ). Stabilize the metatarsal and translate the proximal phalanx dorsally; >50% translation is a positive sign of plantar plate tear.
• Neurovascular check. Pulses, capillary refill, monofilament for sensation, especially in diabetics.
• Skin survey. Corn over PIPJ, callus under metatarsal head, fissures, ulceration.
• Weight-bearing X-rays. AP, lateral, oblique. Confirms joint subluxation, arthritis, length pattern, and rules out fracture.
• MRI — not routine; reserved when plantar plate tear is suspected and it changes surgical planning.

Conservative treatment ladder

Conservative hammertoe treatment is most successful while the deformity is still flexible, with the goal of relieving pain, eliminating skin breakdown, and slowing progression. It will not straighten a rigid contracture — nothing non-surgical can — but it can keep an asymptomatic patient out of the operating room. We start every patient at the conservative ladder, and only climb to surgery if pain, function, or skin integrity fail.

• Footwear change. Wide toe-box, deep soft-upper shoes. Out of pointed dress shoes and out of any shoe whose top hits the dorsal corn. This single change resolves a notable number of mild hammertoes.
• Arch-support insole. An over-the-counter insole like PowerStep Pinnacle Maxx Plus redistributes forefoot pressure off the metatarsal head and reduces the plantar callus that drives the MTPJ subluxation cycle.
• Toe sleeves and pads. Gel toe sleeves cushion the dorsal corn; small horseshoe pads offload the metatarsal head; soft toe crests support the toes from below.
• Toe spacers and splints. Daytime taping or nighttime splints can hold a flexible hammertoe straight and slow stiffening.
• Topical analgesia. A non-greasy menthol gel like Doctor Hoy’s Natural Pain Relief Gel on a flared corn or sore MTPJ before bed reduces day-to-day pain.
• Stretching and intrinsic strengthening. Towel scrunches, marble pickups, short-foot exercises preserve intrinsic muscle bulk that opposes the deformity.
• Professional callus debridement. Routine in-office shaving of the corn and plantar callus — not a cure, but breaks the pain cycle and prevents ulceration.
• Cortisone injection. A small corticosteroid injection at a painful synovitic MTPJ can buy 3 to 6 months in patients delaying surgery; we use it judiciously because steroid weakens the plantar plate.

Hammertoe surgery: arthroplasty, arthrodesis, tendon transfer

Hammertoe surgery is indicated when conservative care fails, the deformity is rigid, the corns are recurrent or ulcerating, or the patient cannot tolerate any closed shoe. The procedure choice is driven by reducibility, joint surface health, MTPJ status, and patient activity. In our practice we tailor the operation to the toe, not the other way around. Below are the four standard procedures and when we choose each.

PIPJ arthroplasty (Du-Vries)

An arthroplasty resects the head of the proximal phalanx, leaving the joint as a flexible pseudoarthrosis. It is fast (10 to 15 minutes), preserves toe length, and has the easiest rehab. Best for moderate flexible-to-semi-rigid hammertoes in older lower-demand patients, especially diabetics where surgical hardware is undesirable.

PIPJ arthrodesis (fusion) with intramedullary implant

Arthrodesis fuses the PIPJ in an anatomically straight position. It is the most powerful and durable correction. Fixation has migrated from external K-wires (still used) to buried intramedullary implants (Smart Toe, Pro-Toe, IPP-On) that eliminate the protruding pin, reduce infection risk, and let patients shower and dress more normally during the heal-in period. Best for rigid hammertoes, athletic patients, and toes that have failed prior arthroplasty.

Flexor-to-extensor tendon transfer (Girdlestone-Taylor)

The flexor digitorum longus is split, rerouted dorsally, and sutured to the extensor expansion. The transfer dynamically rebalances a flexible deformity without bone work. Reserved for flexible hammers in younger patients with healthy joints, often combined with MTPJ release.

MTPJ release / Weil osteotomy / plantar plate repair

When the hammertoe is driven by a hyperextended subluxating MTPJ — classic plantar plate tear — PIPJ surgery alone fails. We release the MTPJ capsule, shorten the metatarsal with a Weil osteotomy, and repair the plantar plate from above. This is the modern correction for the painful subluxating second-toe deformity that has resisted everything else.

Recovery timeline

Hammertoe recovery is fast for a foot operation. The procedure is outpatient under local plus light sedation. Most patients walk out of surgery in a stiff post-operative shoe with full weight bearing on the heel allowed immediately. Pain peaks at 24 to 48 hours and is well controlled with ice, elevation, and oral analgesics — opioids only briefly if at all.

• Week 0–2: Post-op shoe, dressing changes weekly, suture removal at 2 weeks. Elevation 30+ minutes per hour for the first 5 days.
• Week 2–4: Transition to a stiff-soled wide athletic shoe. K-wires (if used) come out at 4 weeks; intramedullary implants stay buried.
• Week 4–6: Edema settles, begin gentle range-of-motion under guidance. Most desk-job patients are back in regular shoes by week 5.
• Week 6–8: Return to running and most exercise. Final correction holds.
• Month 3–6: Residual edema fades. Final cosmetic and functional outcome judged.

The most common mistake we see

The most common mistake we see is patients self-treating a hammertoe by shaving the dorsal corn at home with a razor — sometimes for years — without ever changing the shoe that creates it. Razoring temporarily reduces the corn but never addresses the contracture, and a small slip on a Tuesday night becomes a Stage 1 ulcer by Friday. In a diabetic, the same razor cut reaches the bone in two weeks.

The right pathway is the opposite: change the shoe first, add an arch insole second, see a podiatrist third. Conservative care eliminates the corn in over half of flexible hammertoes. The surgery, when needed, is a 30-minute outpatient operation, not a salvage of an infected toe.

Prevention

Hammertoe prevention is largely about the shoe and the foot mechanics that the shoe exposes. The earlier you change them, the better the result. Patients who change shoes at the first sign of dorsal corn rarely come back; patients who keep wearing the offending shoe always do.

• Wide toe-box, soft-upper shoes; no narrow dress shoes for daily wear
• Half-size larger shoe to accommodate forefoot swelling at end of day
• Arch-support insole if you have a low arch, long second toe, or any forefoot pain
• Daily intrinsic foot exercises — towel scrunches, short-foot drill
• Treat a bunion before it pushes on the second toe
• Annual diabetic foot exam if applicable
• Replace athletic shoes every 500 to 800 miles; the toe box softens and migrates

Frequently asked questions

Can a hammertoe straighten on its own?

A flexible hammertoe in a child or adolescent occasionally improves with growth and footwear change, but in adults a hammertoe never spontaneously straightens. The natural history is progressive stiffening over years to decades. The realistic non-surgical goal is to keep it asymptomatic and slow the progression, not to reverse it.

How painful is hammertoe surgery?

Most patients describe pain as moderate the first 24 to 48 hours, then mild and easily controlled. We use a long-acting local anesthetic block at the end of surgery that typically keeps the toe numb for 12 to 18 hours. Ice, elevation, and a few days of acetaminophen plus an NSAID handle the rest for the majority of patients. Opioids are used briefly or not at all.

Will my hammertoe come back after surgery?

Recurrence after a well-executed PIPJ arthrodesis with implant is uncommon — under 10 percent. Recurrence after arthroplasty alone is higher, especially if the underlying MTPJ instability or bunion was not also addressed. The single biggest predictor of recurrence is going back into the same narrow shoe that caused the deformity in the first place.

When can I drive after hammertoe surgery?

Right-foot procedures: 2 to 4 weeks once you can transition into a stiff-soled regular shoe and brake firmly without pain. Left-foot procedures with an automatic transmission: 2 to 5 days off opioids. We test driving readiness in clinic, and we do not clear patients to drive while still in a post-op shoe on the right foot.

Are toe straighteners worth buying?

For a flexible hammertoe, yes — toe sleeves, gel pads, and silicone splints reduce friction and may slow progression. For a rigid hammertoe, no straightener will reverse the contracture; they only relieve corns. The most consistently effective non-prescription combination we recommend is a wide-toe-box shoe + an arch-support insole + a gel toe sleeve at the affected joint.

Can the hammertoe surgery be done with a Weil osteotomy at the same time?

Yes, and it often should be. When a hammertoe is paired with a long second metatarsal or a plantar plate tear, isolated PIPJ surgery underperforms. We commonly combine PIPJ arthrodesis with a Weil osteotomy of the second metatarsal and, when needed, plantar plate repair through a dorsal approach. The operative time is short (30 to 50 minutes) and the recovery timeline is the same as PIPJ surgery alone.

Dr. Tom’s Hammertoe Product Picks

Conservative management of flexible hammertoe depends on three things: footwear with enough toe box depth, padding that offloads pressure from the PIP joint corn, and silicone splints that slow the contracture. These are the exact products I recommend in clinic, all available on Amazon.

#1 — Wide Toe Box Shoes (Most Important)

The single most important intervention for flexible hammertoe is removing the compressive force from a narrow toe box. Most dress shoes and athletic shoes are too narrow at the toes, pushing the second and third toes into flexion. Wide Toe Box Shoes for Women and Wide Toe Box Shoes for Men — look for at least 4E width with a roomy forefoot and low heel-to-toe drop.

#2 — Hammertoe Crests and Toe Splints

A hammertoe crest pad sits under the affected toe and passively extends the PIP joint, reducing the clawing deformity during walking. Works best for flexible hammertoes still in early stages. Silicone Hammertoe Crest Pads on Amazon — get a 3-pack; they compress over 2–3 months of daily wear.

#3 — Corn and Callus Pads

The corn over the PIP joint is the primary pain generator in most hammertoe cases. Donut-shaped foam pads offload pressure from the corn without restricting circulation. Dr. Scholl’s Corn Cushion Pads — the soft foam ring version, not the medicated discs with salicylic acid (those thin the skin over time).

#4 — Toe Separators

When hammertoe occurs alongside bunion deformity (very common), toe separators reduce the medial deviation force pulling the second toe into hammertoe position. Gel Toe Separators on Amazon — use between the first and second toes during walking hours.

#5 — Custom Orthotics (If Biomechanical)

When hammertoe is driven by excessive pronation or a hypermobile first ray, an OTC arch support can reduce the propulsive force causing toe clawing. PowerStep Pinnacle Maxx — our #1 OTC orthotic for biomechanical hammertoe cases. Semi-rigid shell corrects pronation, lateral wedge controls foot mechanics during push-off.

The bottom line

A hammertoe is a fixable problem at every stage. While it is flexible, change the shoe, add an arch-support insole, pad the corn, and most patients live with it comfortably for years. Once it stiffens, painful, or starts to break the skin, a 30-minute outpatient surgery delivers a definitive result with full recovery in 6 to 8 weeks. The decision is not whether to fix it — it is when, and which version of the fix matches your toe.

Frequently Asked Questions

When should I see a podiatrist?

If symptoms persist past 2 weeks, affect your normal activity, or are accompanied by red-flag symptoms (warmth, redness, swelling, inability to bear weight).

What does treatment cost?

Most diagnostic visits and conservative treatments are covered by Medicare and major insurers. Out-of-pocket costs vary by your specific plan.

How quickly can I get an appointment?

Most non-urgent cases see us within 5 business days. Urgent cases (sudden pain, possible fracture) typically same or next business day.
