| Type | Joint Involved | Deformity | Flexibility | Surgery |
|---|---|---|---|---|
| Hammertoe | Proximal interphalangeal (PIP) joint | PIP flexion contracture; MTP extension; DIP varies | Flexible early; rigid late | PIP arthroplasty (flexible) or arthrodesis (rigid) |
| Claw Toe | MTP hyperextension + PIP + DIP flexion | All three joints: MTP extends, PIP + DIP flex (“claw” shape) | Flexible or rigid; often bilateral | MTP release + PIP arthroplasty/arthrodesis; may need flexor-to-extensor transfer |
| Mallet Toe | Distal interphalangeal (DIP) joint only | DIP flexion contracture only; tip of toe curls down | Flexible early; rigid late | FDL tenotomy (flexible) or DIP arthroplasty (rigid) |

| Procedure | Indication | Technique | Success Rate | Recovery |
|---|---|---|---|---|
| PIP Arthroplasty (Condylectomy) | Flexible or mildly rigid hammertoe | Resects head of proximal phalanx; releases PIP joint; K-wire 3–4 weeks | 80–90% correction; some mobility preserved but reduced | Surgical shoe 4–6 weeks; full shoe 6–8 weeks |

Quick Answer:
Quick Answer: Hammertoes are flexion deformities of the lesser toes involving the PIP, DIP, or MTP joints. Flexible hammertoes respond to shoe modification, padding, and splinting. Rigid hammertoes with painful dorsal corns, ulceration, or MTP joint subluxation require surgical correction: PIP joint arthroplasty or arthrodesis, extensor tendon lengthening, and MTP capsule release. Recovery is 4–6 weeks in a post-operative shoe with early weight-bearing.
Hammertoes — flexion deformities of the lesser toe joints — are among the most common foot problems seen in podiatric practice, affecting millions of Americans and causing significant pain from dorsal corns, shoe friction, and progressive deformity. What begins as a flexible toe that can still be manually straightened progresses, if untreated, to a rigid fixed deformity requiring surgical correction. At Balance Foot & Ankle PLLC, Dr. Tom Biernacki evaluates the specific type and severity of hammertoe deformity to determine the most effective treatment approach for each patient.
Understanding Hammertoe Types
Hammertoe (strict definition): Flexion deformity at the proximal interphalangeal (PIP) joint with the MTP joint in extension. This creates the classic upward-curling appearance with dorsal PIP prominence causing corn formation against shoe upper.
Claw toe: Flexion of both PIP and DIP joints with MTP joint extension. Both joints are flexed, creating a more severe deformity with dorsal and tip corns. Often associated with neurological conditions (Charcot-Marie-Tooth, diabetic neuropathy).
Mallet toe: Isolated DIP joint flexion without PIP or MTP involvement. Causes distal tip corn at the end of the toe — painful with every step.
Flexible vs. Rigid: Flexible hammertoes can be passively corrected — the joint can be manually straightened. Rigid hammertoes have fixed contracture — the joint cannot be straightened passively. Treatment differs significantly.
Causes of Hammertoe Development
Hammertoes develop from chronic imbalance between the intrinsic (lumbrical) and extrinsic (flexor/extensor) muscles acting on the toe — the extrinsic flexors overpower the intrinsics, producing progressive flexion. Causes include: narrow-toed or high-heeled shoes that force toes into flexion chronically, underlying bunion deformity forcing the 2nd toe into malposition, plantar plate rupture allowing dorsal MTP subluxation, neuromuscular conditions affecting intrinsic muscle strength, and trauma.
Conservative Treatment
For flexible hammertoes: toe splinting/strapping in corrected position, toe spacers/separators to prevent medial/lateral deviation, footwear modification (wide toe box, extra depth to accommodate the deformity), corn pads for dorsal PIP prominence, and physical therapy for intrinsic muscle strengthening. Conservative treatment does not reverse flexible hammertoes — it manages symptoms and slows progression. Once rigidity develops, surgery is the only option for correction.
Surgical Correction
PIP arthroplasty: The condyles of the proximal phalanx are resected at the PIP joint through a small dorsal incision, relieving the contracture. The PIP joint is straightened and held with a temporary K-wire for 3–4 weeks. Simple, effective for most rigid hammertoes without severe MTP subluxation. Recovery: post-op shoe 4–6 weeks; return to regular shoes at 6–8 weeks.
PIP arthrodesis: The joint surfaces are prepared for fusion instead of arthroplasty — used for severe deformity or when long-term stability is critical. The toe is permanently straightened at the PIP level.
Concurrent procedures: When MTP joint subluxation or plantar plate tear coexists, Weil shortening osteotomy decompresses the MTP joint and allows plantar plate repair simultaneously. Extensor tendon lengthening (Z-tenotomy or EHL tenotomy) is performed when extensor tightness contributes to deformity.

✅ Pros / Benefits
- PIP arthroplasty achieves reliable hammertoe correction with rapid recovery — shoes at 6–8 weeks
- Early-stage flexible hammertoe management with footwear and splinting slows progression
- Concurrent Weil osteotomy addresses plantar plate tear and MTP subluxation simultaneously
❌ Cons / Risks
- Conservative care does not reverse hammertoe deformity — it manages symptoms only
- K-wire fixation after arthroplasty requires 3–4 weeks pin care and restricted activity
- Hammertoe recurrence can occur if underlying bunion deformity is not corrected simultaneously
Dr. Tom Biernacki’s Recommendation
Hammertoe surgery is one of the most immediately gratifying operations I perform. Patients who’ve had a corn on their 2nd toe for 5 years, tried every pad and gel treatment, and finally decide to have it corrected — they come back at 8 weeks in regular shoes with no pain, no corn, no restriction. The PIP arthroplasty is a small operation with a predictable result. The key is doing the right concurrent procedures: if there’s a plantar plate tear at the MTP joint, I’m doing a Weil osteotomy at the same time. And if there’s a bunion pushing that 2nd toe laterally, we address the bunion simultaneously — otherwise the hammertoe is likely to recur.

Frequently Asked Questions
Can hammertoes be fixed without surgery?
Flexible hammertoes — those that can still be manually straightened — can be managed conservatively with toe splints, wide toe box footwear, corn pads, and physical therapy for intrinsic strengthening. Conservative care controls symptoms and slows progression but does not permanently correct the deformity. Once a hammertoe becomes rigid (fixed) and cannot be passively straightened, surgery is the only option for correction. Early intervention before rigidity develops maximizes conservative care options.
How long is recovery after hammertoe surgery?
PIP arthroplasty or arthrodesis allows immediate protected weight-bearing in a post-operative surgical shoe. K-wire removal occurs at 3–4 weeks. Return to regular footwear at 6–8 weeks. Return to athletic activity at 10–12 weeks. Swelling typically persists for 3–4 months. Combined hammertoe and bunion correction requires additional recovery time. Dr. Biernacki provides specific recovery timelines based on the procedures performed.
Are hammertoes genetic?
Yes, partly. Foot structure — long second toe (Morton’s toe), high arch, flexible flatfoot — creates biomechanical predisposition to hammertoe development. Family history is common. However, footwear plays a major role: narrow toe box, pointed shoes, and high heels that crowd the toes and force chronic flexion dramatically accelerate deformity in genetically susceptible individuals. Wearing appropriate wide toe box footwear from a young age reduces hammertoe progression significantly.
Does hammertoe correction hurt?
Hammertoe surgery is performed under local anesthesia (toe block) with sedation — patients feel no pain during the procedure. Post-operative pain is typically mild — most patients manage with OTC analgesics after the first 48 hours. The toe is swollen, stiff, and tender for 6–8 weeks, but sharp pain is uncommon with proper surgical technique. Dr. Biernacki provides detailed post-operative pain management instructions and is available for questions during recovery.
