Hammertoe Treatment:
From Conservative Care to Surgery
Hammertoes are progressive — they worsen over time and do not resolve on their own. Our board-certified foot and ankle surgeons in San Jose, Mountain View, Los Gatos, and Monterey offer the full spectrum of hammertoe care, from the most conservative options to the latest minimally invasive surgical techniques.
A hammertoe starts as a minor annoyance — a toe that curls slightly, a corn that forms on top of it, a shoe that no longer fits right. Left untreated, that flexible deformity hardens into a rigid, permanent bend that causes pain with every step and makes finding comfortable footwear nearly impossible. This guide explains exactly what is happening in your toe, why it progresses, and what your options are — from the most conservative to the most definitive.
What Is a Hammertoe? Understanding the Deformity
A hammertoe is a progressive deformity of one or more of the smaller toes — typically the second, third, or fourth toe — in which an abnormal bend develops at the middle joint of the toe, causing it to curl downward like a hammer striking a surface. What begins as a subtle positional change driven by muscle-tendon imbalance gradually becomes a fixed, rigid deformity that causes pain, skin breakdown, and significant difficulty with footwear.
To understand why a hammertoe forms, it helps to understand the normal mechanics of the toe. Each lesser toe has three bones (phalanges) connected by two joints, and its position is controlled by a balance of tendons — the extensor tendons on top that pull the toe upward and the flexor tendons underneath that pull it downward. When this balance is disrupted — by footwear that compresses the toes, by mechanical changes in the foot caused by a bunion or flatfoot, or by neurological conditions that alter muscle function — the toe is pulled into an abnormally bent position. Over time, the tendons and joint capsule tighten around the bent position, and the toe loses its ability to straighten.
The critical clinical distinction is between flexible hammertoes — those that can still be manually straightened — and rigid hammertoes — those that are permanently fixed in the bent position. This distinction determines which treatment options are appropriate and how urgently treatment should be pursued.
| Feature | Flexible Hammertoe | Rigid Hammertoe |
|---|---|---|
| Can be manually straightened | Yes — passive correction possible | No — fixed in bent position |
| Stage of progression | Early to moderate | Advanced |
| Conservative treatment effective | Often — splints, orthotics, footwear | Manages symptoms only; does not correct |
| Surgical options | Soft tissue release; tendon lengthening | Bone resection (arthroplasty or arthrodesis) |
| Urgency of intervention | Sooner is better — prevents rigidity | Surgery is the only corrective option |
Every flexible hammertoe will eventually become rigid if not addressed. The window for conservative treatment — when the toe can still be straightened and the soft tissue imbalance corrected without bone surgery — closes gradually as the deformity progresses. Early evaluation and treatment produces the simplest procedure and the fastest recovery. If your toe is starting to curl, the best time to see a podiatrist is now — not when it causes a wound or stops fitting into any shoe you own.
Hammertoe vs. Claw Toe vs. Mallet Toe — What’s the Difference?
The terms hammertoe, claw toe, and mallet toe are often used interchangeably — but they describe three distinct deformities based on which joint or joints are involved. Understanding the difference matters for treatment, because each deformity has a specific anatomy and responds to different interventions.
Hammertoe
The proximal interphalangeal (PIP) joint — the middle joint of the toe — bends abnormally downward while the tip of the toe may point down or remain flat. The toe looks like a hammer or tent. Most commonly affects the second toe, particularly when a bunion is present that pushes the big toe into the second toe’s space. Most common lesser toe deformity seen in clinical practice.
Mallet Toe
The distal interphalangeal (DIP) joint — the joint closest to the toenail — bends downward while the rest of the toe remains relatively straight. The tip of the toe curls under, often developing a painful corn on the tip or beneath the toenail. Less common than hammertoe and often related to ill-fitting footwear that puts pressure on the tip of the toe.
Claw Toe
Both the PIP and DIP joints are flexed simultaneously while the metatarsophalangeal (MTP) joint — where the toe meets the foot — hyperextends upward. This produces a dramatic claw-like appearance, with the toe curling under so severely that the tips dig into the ground. Claw toes are most strongly associated with neurological conditions such as Charcot-Marie-Tooth disease, diabetes, and alcoholic neuropathy, and often affect multiple toes simultaneously.
The specific joint involved determines which tendons are imbalanced, which surgical approach is most effective, and what conservative measures are most appropriate. A patient with a true hammertoe involving only the PIP joint may be treated very differently from a patient with claw toes affecting multiple digits due to peripheral neuropathy. Accurate diagnosis by a board-certified podiatrist is the essential first step before any treatment decision is made.
Symptoms of Hammertoe
Hammertoe symptoms range from mild cosmetic concerns in the earliest stages to severe pain and wound formation in advanced cases. The progression of symptoms typically mirrors the progression of the deformity — and early recognition of warning signs is the key to simpler, more effective treatment.
Common Symptoms
When Is a Hammertoe a Medical Emergency?
For most patients, hammertoe is a chronic, progressive problem rather than an acute emergency. However, certain situations require prompt evaluation — especially for diabetic patients and those with poor circulation, in whom a skin breakdown over a hammertoe can rapidly progress to a serious infection.
If you have diabetes, peripheral neuropathy, or peripheral arterial disease and notice any break in the skin over a hammertoe — even a small wound that doesn’t hurt because you have sensory loss — call our office for a same-day appointment. In patients with compromised healing, what appears to be a small skin abrasion over a hammertoe can become a deep tissue infection or osteomyelitis within days without appropriate treatment. Do not wait. Do not self-treat.
Causes and Risk Factors
Hammertoes develop from a fundamental imbalance between the muscles and tendons that control toe position. When the forces pulling the toe upward and downward become unequal — for whatever reason — the toe is progressively drawn into a flexed position. Over time, the soft tissue structures adapt to and reinforce this abnormal position until the deformity becomes permanent.
The Most Common Causes
Ill-Fitting Footwear
Shoes with narrow toe boxes or high heels are the single most common contributing factor to hammertoe development. A narrow toe box compresses the toes into a flexed position for hours at a time. High heels shift body weight forward onto the toes and create mechanical stress that imbalances the flexor and extensor tendons. This explains why hammertoes are four times more common in women than men.
Bunion Deformity (Hallux Valgus)
A bunion pushes the big toe laterally toward the second toe — occupying the second toe’s space and forcing it upward and into flexion. Hammertoe of the second toe is one of the most common secondary complications of an untreated bunion. In many cases, correcting the bunion deformity is an important part of the overall hammertoe treatment plan.
Flatfoot or High Arch
Both extreme flatfoot (pes planus) and high-arched foot (pes cavus) alter the mechanical forces on the lesser toes and predispose to hammertoe formation. High-arched feet in particular are strongly associated with claw toe deformities due to the increased pull of the intrinsic muscles of the foot in maintaining arch position.
Peripheral Neuropathy
Neurological conditions that weaken the intrinsic muscles of the foot — including Charcot-Marie-Tooth disease, diabetic neuropathy, and stroke — produce the muscle imbalance that drives claw toe deformities. These cases often involve multiple toes and require a broader treatment approach that addresses the neurological driver, not just the toe deformity itself.
Toe Injury or Surgery
A prior fracture, tendon injury, or previous foot surgery can disrupt the muscle-tendon balance around the lesser toes and produce a hammertoe deformity as a late consequence. In some patients, hammertoe develops years after an apparently well-healed toe injury.
Inherited Foot Structure
Certain foot shapes and proportions are inherited — particularly a long second toe (a “Greek” foot type) or a structurally flat or high-arched foot — that predispose to hammertoe formation regardless of footwear habits. Patients with these structural features should be especially attentive to footwear choices and early hammertoe symptoms.
Risk Factors
How Is a Hammertoe Diagnosed?
Hammertoe diagnosis is primarily clinical — a thorough physical examination by a board-certified podiatrist is usually sufficient to confirm the diagnosis, classify the type and severity of the deformity, and identify any contributing conditions. Imaging plays a supporting role.
-
1Clinical History Your podiatrist will ask about the duration and progression of the deformity, the nature of your symptoms (pain, skin breakdown, footwear difficulty), prior treatments, your footwear habits, your medical history (particularly diabetes, neuropathy, or prior foot surgery), and your activity goals. This history informs the urgency and nature of the treatment approach.
-
2Physical Examination The key clinical assessment is whether the deformity is flexible or rigid — can the toe be passively straightened to its neutral position? The examiner will also assess the position of each joint of the toe, identify any associated corns or calluses, evaluate the skin and soft tissue overlying the joint, and assess for concurrent deformities such as bunion, flatfoot, or metatarsalgia. In diabetic patients, a monofilament sensory test and pedal pulse assessment are included.
-
3Weight-Bearing X-Rays Standing (weight-bearing) X-rays of the foot are obtained to visualize the alignment of the metatarsals, the degree of joint contracture, and the presence of any arthritis within the affected joints. X-rays are also essential for surgical planning — determining whether bone resection is needed and at which level.
-
4Assessment of Contributing Factors Identifying the cause of the hammertoe is as important as documenting the deformity itself. The examiner will specifically evaluate for a bunion driving the second toe deformity, flatfoot altering forefoot mechanics, neurological changes affecting muscle balance, and footwear-related factors. Addressing contributing causes is essential for preventing recurrence after treatment.
Conservative Treatment — Non-Surgical Options
Conservative treatment for hammertoe is most effective for flexible deformities — those that can still be manually straightened. The goals are to reduce pain, prevent progression, protect the skin, and improve shoe fit. It is important to understand that conservative treatment manages the symptoms of a hammertoe; it does not correct the underlying deformity. As the deformity progresses from flexible to rigid, conservative measures become less effective.
Footwear Modification
The single most important conservative intervention. Shoes with a wide, deep toe box that allows the toes to rest without compression eliminate the primary mechanical driver of hammertoe progression. Shoes should be measured properly — many adults wear shoes one to two sizes too small. High heels should be avoided or minimized. Shoe stretching at the toe box area can help accommodate existing deformities.
Toe Splints and Straighteners
Hammertoe splints and toe straightening devices apply gentle corrective force to a flexible hammertoe, holding the toe in a more neutral position during wear. They are most effective at preventing progression when used consistently over time — not for correcting established rigid deformities. A variety of designs are available; your podiatrist will recommend the most appropriate type for your specific deformity pattern.
Padding and Corn Management
Donut-shaped pads placed over the prominent PIP joint protect the overlying skin from shoe pressure and reduce the pain of corns. Corn removal (debridement) performed by a podiatrist safely removes the thickened skin that accumulates over hammertoe joints, relieving pain and preventing the skin breakdown that can lead to open wounds — particularly important in diabetic patients.
Custom Orthotics
Custom foot orthotics can address the biomechanical drivers of hammertoe formation — redistributing forefoot pressure away from the metatarsal heads beneath affected toes, correcting flatfoot mechanics that overload the lesser toes, and providing metatarsal padding that offloads the ball of the foot. Orthotics do not correct an existing hammertoe but are an important adjunct to surgery for preventing recurrence.
Toe Stretching and Exercises
For early, flexible hammertoes, gentle stretching exercises to maintain extensor tendon flexibility and intrinsic muscle strength can help slow progression. Towel-curling exercises, marble pickup, and toe extension stretches are commonly prescribed. These exercises are most beneficial when started early and practiced consistently — they are rarely sufficient on their own to prevent progression in an established deformity.
Corticosteroid Injections
A corticosteroid injection into the MTP joint or the inflamed bursa overlying a hammertoe can provide significant short-term pain relief and reduce inflammation, making it easier to tolerate conservative footwear modifications and splinting. Injections are a temporizing measure, not a curative one — they do not address the structural deformity.
Conservative measures should be tried for a reasonable period — typically 3 to 6 months — before surgical intervention is considered. However, surgical evaluation is appropriate sooner when the deformity is already rigid (surgery is the only corrective option), when skin breakdown or open wounds are present, when a diabetic or at-risk patient has developed any wound over the deformity, or when the patient’s quality of life and functional activity are significantly limited. Continuing conservative treatment indefinitely in the face of a progressive, rigid deformity simply delays necessary treatment.
Hammertoe Surgery — When and How
Hammertoe surgery is one of the most common podiatric surgical procedures — and one of the most reliably successful. When a hammertoe has progressed to the point where conservative treatment cannot adequately control symptoms, surgical correction provides definitive, durable relief. The specific procedure depends on whether the hammertoe is flexible or rigid, the extent of joint contracture, and the presence of concurrent forefoot conditions like bunion or metatarsalgia.
Surgical Procedures for Hammertoe
| Procedure | Best For | What Is Done | Fixation |
|---|---|---|---|
| Flexor Tendon Release | Flexible hammertoe, mild deformity | The tight flexor tendon beneath the toe is released through a small incision, allowing the toe to straighten | No implant — toe position maintained with splinting during healing |
| Digital Arthroplasty (PIP Joint Resection) | Rigid or semi-rigid hammertoe | A small portion of bone is removed from the PIP joint, eliminating the bony block that prevents straightening. The toe is then held straight during healing. | Temporary percutaneous pin (removed in office at 4 weeks) or absorbable device |
| Digital Arthrodesis (PIP Fusion) | Severe, rigid hammertoe; recurrent hammertoe | The PIP joint is removed and the two adjacent bones are fused together in a straightened position — creating a permanently straight segment | Intramedullary implant (SmartToe®, StayFuse®) or pin fixation |
| Extensor Tendon Lengthening | Combined with other procedures when extensor is overly tight | The tight extensor tendon on top of the toe is lengthened to allow the toe to rest in a neutral position | Suture only — no implant required |
| MTP Joint Release (Plantar Plate Repair) | Hammertoe with associated MTP instability or crossover toe | The plantar plate — the soft tissue structure at the base of the toe that stabilizes the MTP joint — is repaired or reconstructed to correct the root driver of the deformity | Suture anchor fixation |
| Metatarsal Osteotomy (Weil Osteotomy) | Hammertoe associated with a long metatarsal or metatarsalgia | A precisely angled cut is made in the metatarsal bone to shorten and/or elevate it, relieving excess pressure at the MTP joint | One or two small screws |
What to Expect: The Surgical Experience
-
1Anesthesia — Local Block + Sedation Hammertoe surgery is performed under local anesthesia with sedation — a digital nerve block numbs the toe completely, and mild IV sedation keeps you comfortable and relaxed during the procedure. General anesthesia is rarely required. Most patients are awake and conversational throughout the procedure without any discomfort.
-
2Outpatient Surgery — Home the Same Day All hammertoe procedures are performed on an outpatient basis. You arrive at the surgical center, have your procedure (typically 30 to 60 minutes per toe, depending on complexity), and return home the same day. You will need a driver — driving yourself is not safe with a surgical dressing on your foot.
-
3Immediate Post-Operative Weight-Bearing Unlike many foot and ankle procedures that require weeks of non-weight-bearing, most hammertoe surgeries allow immediate protected weight-bearing in a post-operative shoe with a stiff sole on the day of surgery. This shoe protects the surgical site and prevents the toe from bending while the healing occurs.
-
4Combining Hammertoe Surgery with Bunion Correction Because bunion and hammertoe frequently occur together, they are often corrected in the same operative session. Addressing both deformities simultaneously means one anesthesia event, one recovery period, and the most biomechanically complete correction. If a bunion is pushing the second toe into a hammertoe position, failing to correct the bunion at the same time risks recurrence of the hammertoe.
Our surgeons are trained in minimally invasive hammertoe correction techniques — performing flexor tendon releases and bony corrections through very small puncture incisions rather than traditional open cuts. Minimally invasive approaches result in significantly less soft tissue disruption, reduced post-operative swelling, minimal scarring, and faster return to comfortable footwear. Not every hammertoe is best suited to a minimally invasive approach — your surgeon will assess your specific deformity and recommend the technique most likely to produce the best long-term outcome.
Recovery After Hammertoe Surgery
Hammertoe surgery recovery is generally well-tolerated and faster than many patients expect. The most important factors in a smooth recovery are elevating the foot, protecting the surgical dressing, wearing the post-operative shoe consistently, and attending all follow-up appointments. Patients who follow post-operative instructions carefully consistently report the best outcomes and fastest recovery.
| Phase | Timeline | What to Expect |
|---|---|---|
| Immediate Post-Op | Days 1–3 | Elevate the foot above heart level as much as possible. Surgical dressing in place. Walk only as needed in the post-operative shoe. Ice packs over the dressing reduce swelling. Pain is typically managed with oral medication and rarely severe. |
| Early Healing | Weeks 1–3 | First post-operative visit for wound check and dressing change. Pin removal (if used) occurs at approximately 3 to 4 weeks. Swelling begins to reduce but remains significant. Continue wearing post-operative shoe at all times when walking. |
| Intermediate Recovery | Weeks 4–6 | Physical therapy begins to restore toe flexibility and reduce scar tissue formation. Toe taping to maintain alignment continues. Most patients transition toward a wide, accommodative athletic shoe as swelling allows. |
| Return to Normal Footwear | Weeks 6–8 | Most patients fit comfortably into normal footwear by 6 to 8 weeks. Custom orthotics are often prescribed at this stage to support the correction and prevent recurrence. Dress shoes may take an additional 4 to 6 weeks. |
| Full Recovery | 3–4 Months | Residual swelling resolves completely. Return to all athletic activities. Final assessment of alignment and correction. If a fusion was performed, X-ray confirmation of bone healing is obtained. |
Swelling is the most common source of post-operative discomfort after hammertoe surgery and the most common reason patients feel their recovery is slower than expected. The foot is the most gravity-dependent structure in the body, and swelling naturally accumulates there. The most effective management is elevation above heart level whenever you are not walking — not just raising the foot to couch height, but genuinely above the level of the heart. Consistent elevation during the first two weeks dramatically reduces swelling and pain and accelerates all subsequent recovery milestones.
Prevention — Stopping Hammertoes Before They Start
Not all hammertoes are preventable — inherited foot structure and neurological conditions are beyond individual control. But the most common cause of hammertoe development — footwear-induced mechanical stress — is entirely preventable with the right choices. And for patients who have already had hammertoe surgery, prevention of recurrence is essential for maintaining the correction.
Hammertoe surgery corrects the deformity — but it does not eliminate the mechanical forces that caused it. Without addressing the underlying causes, recurrence is possible. The most important post-surgical preventive measures are: wearing appropriate footwear with a wide toe box consistently; using custom orthotics to redistribute forefoot pressure; addressing any concurrent bunion deformity; and attending regular follow-up visits so that any early signs of recurrent deformity can be identified and managed before they become rigid again.

Frequently Asked Questions About Hammertoes
A hammertoe is a progressive deformity in which one or more of the smaller toes develops an abnormal downward bend at the middle joint, caused by an imbalance between the muscles and tendons that control toe position. The most common causes are shoes with narrow toe boxes or high heels that compress and chronically flex the toes, a bunion deformity that pushes the big toe into the second toe’s space, flatfoot or high-arch foot structure that alters forefoot mechanics, and neurological conditions that weaken the intrinsic muscles of the foot. The deformity is progressive — it will worsen over time without treatment.
Yes — but only while the deformity is still flexible (the toe can be manually straightened). Flexible hammertoes can be managed conservatively with wide toe-box footwear, toe splints, padding, custom orthotics, and corticosteroid injections. These measures reduce symptoms and slow progression but do not correct the deformity. Once the hammertoe becomes rigid — fixed in the bent position — surgery is the only way to straighten the toe. This is why early evaluation and treatment is so important: the window for conservative management is limited.
Hammertoe surgery typically takes 20 to 45 minutes per toe depending on the complexity of the procedure, and is performed as an outpatient procedure. Most patients are able to walk immediately after surgery in a specialized post-operative shoe with a rigid, flat sole that protects the toe while bearing weight. You will not be in a cast or on crutches in most cases. You will need a driver on the day of surgery and should plan to elevate the foot for the first several days.
Both are deformities of the lesser toes, but they differ in which joints are involved. A hammertoe bends abnormally at the proximal interphalangeal (PIP) joint — the middle joint of the toe — while the other joints remain relatively normal. A claw toe bends at both the PIP and distal interphalangeal (DIP) joints simultaneously while the MTP joint (where the toe meets the foot) hyperextends upward, creating a dramatic claw-like appearance. Claw toes are most strongly associated with neurological conditions affecting the intrinsic muscles of the foot. A mallet toe bends only at the DIP joint — the joint closest to the toenail — while the rest of the toe remains relatively straight.
Hammertoe surgery is performed under a digital nerve block — a local anesthetic that numbs the toe completely — combined with mild sedation for comfort. Most patients feel no discomfort during the procedure. After surgery, as the nerve block wears off over 6 to 12 hours, oral pain medication manages discomfort effectively. Most patients report that the post-operative pain is milder than they anticipated. Swelling is the most common source of post-operative discomfort — elevation of the foot above heart level is the most important measure for managing it.
Most PPO insurance plans and Medicare cover hammertoe surgery when it is medically necessary — meaning the deformity causes pain, functional limitation, skin breakdown, or recurrent wounds that have not adequately responded to conservative treatment. Purely cosmetic hammertoe correction is not typically covered. Documentation of the deformity, symptoms, and prior conservative treatment attempts is required for coverage approval. Our billing team is experienced in obtaining pre-authorization for hammertoe procedures and will verify your specific coverage before your consultation.
Hammertoe recurrence is possible, particularly if the underlying causes are not addressed after surgery. The most common reasons for recurrence are continuing to wear inappropriate footwear with a narrow toe box, failing to correct a concurrent bunion that is mechanically pushing the toe back into flexion, and not using custom orthotics to redistribute forefoot pressure. Arthrodesis (fusion) procedures have lower recurrence rates than arthroplasty (joint resection) because the corrected position is permanently locked rather than maintained by soft tissue healing alone. Your surgeon will discuss the most appropriate procedure and the post-operative prevention plan for your specific case.
Yes — a “crossover toe” or “floating toe” (where the second toe drifts upward and over the big toe) is a specific hammertoe variant associated with plantar plate insufficiency at the second MTP joint. The plantar plate is a fibrocartilaginous structure at the base of the toe that normally holds it in proper alignment. When this structure is overstretched or torn — often from chronic forefoot overload or from a bunion mechanically destabilizing the second toe — the toe begins to drift upward and medially, eventually crossing over the big toe. This condition typically requires plantar plate repair in addition to toe straightening for durable correction. It should be evaluated and addressed sooner rather than later, as it progresses rapidly once established.
