Quick answer: Hammertoes occur when a toe bends abnormally at the middle joint, causing pain, corns, and difficulty wearing shoes. Our Michigan podiatrists treat hammertoes with splinting, padding, and custom orthotics — and offer minimally invasive surgical correction for flexible and rigid hammertoes that fail conservative care.
Hammertoe Surgery: Procedure Selection by Deformity Type and Flexibility
Hammertoe surgery is not one procedure — it is a family of procedures chosen based on whether the deformity is flexible (correctable with passive manipulation) or rigid (fixed contracture), which joint is primarily affected (PIP vs MTP), and whether concurrent bony pathology exists. Choosing the right procedure for the deformity type is the primary determinant of surgical success. Here is the evidence-based procedure selection matrix used at our Michigan podiatry practice.
| Deformity Type | Flexibility | Surgical Procedure | Fixation | Union / Success Rate | Return to Shoe |
|---|---|---|---|---|---|
| PIP flexion contracture (classic hammertoe) | Flexible: PIP corrects to neutral with passive extension | PIP flexor tendon release (tenotomy) ± extensor tendon lengthening; preserves joint; no bone removal; appropriate for flexible deformity only | None; buddy tape 4-6 weeks | 85-90% improvement; may recur if MTP instability not addressed; recurrence rate higher than arthroplasty at 5 years | Wide shoe day 1-2; normal shoe 4-6 weeks |
| PIP flexion contracture (rigid hammertoe) | Rigid: PIP does NOT passively correct; fixed bone contracture | PIP arthroplasty (condylectomy): remove head of proximal phalanx to create pseudarthrosis; or PIP fusion (arthrodesis): fuse PIP in corrected position with pin or implant | K-wire (4-6 weeks for arthroplasty); intramedullary implant or screw for fusion (permanent) | Arthroplasty: 80-85% good outcomes; 10-15% recurrence; higher motion but less correction stability. Fusion: 90-95% correction maintained; no recurrence; toe is stiff at PIP permanently | Surgical shoe 3-4 weeks; normal shoe 4-8 weeks (arthroplasty); 6-8 weeks (fusion) |
| MTP joint instability / crossover toe | MTP subluxed or dislocated; 2nd toe crossing over hallux; plantar plate torn | MTP joint correction: metatarsal osteotomy (Weil osteotomy) shortens the MT to reduce MTP joint loading; concurrent plantar plate repair if torn; extensor tendon release at MTP level | 1-2 metatarsal head screws (permanent); K-wire through toe if concurrent PIP work | 90%+ correction of MTP position; plantar plate repair adds 85-90% success for joint stability; Weil osteotomy with plantar plate repair is the most durable construct for crossover toe | Surgical shoe 4-6 weeks; normal shoe 8-10 weeks; stiff shoe while osteotomy heals; K-wire removal at 3-4 weeks if used |
| Mallet toe (DIP flexion contracture) | Flexible or rigid; DIP joint curled downward; tip of toe painful on ground | Flexible: FDL tendon release at DIP; Rigid: DIP condylectomy (remove distal phalanx head) or DIP fusion; nail removal if concurrent subungual corn | DIP fusion: K-wire 4-6 weeks; heals in functional position | 85-90% good outcomes; significantly less studied than hammertoe; DIP fusion provides most stable correction for rigid mallet toe | Normal shoe 2-4 weeks for tendon release; 4-6 weeks for fusion |
Hammertoe: Conservative Treatment Before Surgery
| Treatment | Works For | Success Rate | How Long to Trial | Stops Progression? |
|---|---|---|---|---|
| Wide toe box shoes | All flexible and early rigid hammertoes; eliminates shoe-against-toe friction that causes corns and bursitis; essential first intervention | 80-90% corn and pain elimination for mild-moderate flexible hammertoe; does not correct the deformity but eliminates most symptoms | Permanent change — all footwear including casual; narrow shoes are contraindicated indefinitely; if pain resolves with correct footwear, surgery may not be needed | No — deformity continues to progress but symptoms are managed; stops further shoe aggravation |
| Toe spacers / silicone toe sleeves | Reduces interdigital corn friction; prevents 2nd toe contact with hallux; mild deformity management | 60-70% symptom relief for flexible hammertoe with interdigital corn; modest correction effect on flexible deformity while worn (reverts when removed) | Trial 6-8 weeks; use daily inside shoes; replace every 3-6 months as silicone degrades | No structural effect; flexible deformities managed but do not regress |
| Custom orthotics with metatarsal accommodation | Hammertoe with concurrent plantar metatarsalgia or MTP joint instability; flat feet driving hammertoe progression | 50-70% pain reduction for metatarsalgia component; addresses pronation mechanism driving deformity; most effective combined with wide shoes | 6-8 weeks with consistent use; re-evaluate for surgical referral if no improvement at 3 months | May slow progression by reducing MTP joint overload; does not reverse established rigid deformity |
| Corn/callus management | All hammertoe patients with dorsal PIP corn or plantar tip corn; reduces the painful symptoms while managing the deformity non-surgically | Temporary — corn returns within weeks without deformity correction; regular debridement (every 4-8 weeks) manages symptoms indefinitely; urea cream 20-40% slows corn regrowth | Ongoing management; not a curative treatment; appropriate for patients who cannot or choose not to have surgery | No deformity effect; symptom management only |
| Splinting / tape corrective | Flexible hammertoe only; buddy taping or toe loop splint corrects position while worn; no effect on rigid deformity | 30-50% functional improvement for flexible deformity during high-activity periods; night splinting has limited evidence for deformity progression prevention | Trial 6-8 weeks for flexible deformity before considering surgery; flexible hammertoe that responds to splinting may not require surgical intervention | Limited — splinting does not reverse deformity or prevent progression when deformity is moderate or severe |

Quick Answer:
Quick Answer: Hammertoe is a flexion contracture of the proximal interphalangeal (PIP) joint of the lesser toes, causing dorsal prominence and corn formation. Flexible hammertoes (correct with passive pressure) respond to footwear modification and toe splinting. Rigid hammertoes require surgical correction: PIP arthroplasty (removal of the articular surface and realignment) or PIP fusion (bone-to-bone healing for lasting correction). Recovery: walking immediately in a surgical shoe.
Hammertoe deformity — flexion contracture of the proximal interphalangeal (PIP) joint of the lesser toes — is one of the most common foot deformities treated by podiatrists. The bent toe creates a dorsal prominence that rubs against shoe upper, causing corn formation, pain, and nail deformity. Hammertoe is frequently associated with hallux valgus (bunion), as the drifting big toe destabilizes the 2nd toe, and with flatfoot, which overloads the lesser metatarsals. At Balance Foot & Ankle PLLC, Dr. Tom Biernacki offers comprehensive hammertoe management from conservative measures to surgical correction.
Flexible vs. Rigid Hammertoe
Flexible Hammertoe: The deformity corrects with passive pressure — the toe can be manually straightened. Conservative management is appropriate: wider toe box footwear, toe separators, gel toe caps to cushion the dorsal prominence, and hammertoe splints. Padding the corn and ensuring wide footwear may provide long-term adequate control. Rigid Hammertoe: The deformity does not correct passively — the PIP joint is fixed in flexion by contracted soft tissue and bony changes. Conservative measures manage symptoms but cannot correct the deformity. Surgical correction is needed for lasting resolution.
Surgical Correction
PIP Arthroplasty (condylectomy/phalangeal head resection): The articular cartilage surface of the proximal phalanx head is removed, allowing the toe to straighten. The toe is held in corrected position with a temporary Kirschner wire (K-wire) for 4–6 weeks. Flexible cartilage tissue bridges the resection. Simple, highly effective procedure. PIP Fusion (arthrodesis): Both articular surfaces removed and bone-to-bone healing achieved with a small intramedullary screw or K-wire. Produces rigid but straight toe — preferred for severe or recurrent deformities. Recovery for both: immediate walking in a surgical shoe, K-wire removal (if used) at 4–6 weeks, regular footwear by 4–6 weeks. The correction is highly durable with appropriate fixation.
Addressing Associated Deformities
Hammertoe correction is often performed simultaneously with bunionectomy when hallux valgus is driving the 2nd toe deformity, and with Weil osteotomy (metatarsal shortening) when metatarsal prominence is contributing to plantar plate injury and toe instability. Addressing all components of the deformity simultaneously produces the most durable correction.

✅ Pros / Benefits
- PIP arthroplasty and fusion both highly effective with immediate postoperative weightbearing
- Simultaneous bunionectomy and hammertoe correction addresses all deformity components in one surgery
- K-wire provides temporary fixation without a second surgery if used with planned removal
- Intramedullary screw for fusion eliminates K-wire complications and external hardware
❌ Cons / Risks
- K-wire removal at 4-6 weeks requires an additional office procedure
- Rigid hammertoe toe may feel stiff after PIP fusion — expected and generally well tolerated
- Recurrence is possible if driving bunion deformity is not simultaneously corrected
Dr. Tom Biernacki’s Recommendation
Hammertoe surgery is one of the highest patient-satisfaction procedures I perform. Patients who have been unable to wear normal shoes because of a painful bent toe walk out of surgery in a surgical shoe and into regular footwear within 4-6 weeks. The surgical shoe phase is the main inconvenience — but the straight, comfortable toe they end up with makes it very worthwhile. Fixing the bunion at the same time when it’s driving the hammertoe is important for lasting results.

Frequently Asked Questions
Can hammertoes be treated without surgery?
Flexible hammertoes — those that passively correct with manual pressure — can often be adequately managed with footwear modification (wide toe box, low heel), toe splints, and gel cushions. Rigid hammertoes — fixed contractures — cannot be corrected conservatively and require surgery for lasting resolution. Conservative care for rigid hammertoes manages symptoms (corn padding, wider shoes) but does not correct the deformity.
How long is recovery after hammertoe surgery?
Patients walk immediately after surgery in a surgical shoe or walking boot. The K-wire or screw maintains the correction during healing. Regular footwear transition occurs at 4–6 weeks in most cases. Mild toe swelling persists for 3–4 months — completely normal. Return to athletic footwear and sport: 6–10 weeks depending on the complexity of the surgery.
Will my hammertoe come back after surgery?
Recurrence risk is low with appropriate surgical technique and simultaneous correction of driving deformities. If a bunion is causing the hammertoe and is not corrected simultaneously, hammertoe recurrence is more likely. PIP fusion produces more durable correction than arthroplasty for severe or recurrent deformities. Custom orthotics post-surgery help maintain alignment.
Do all toes need to be corrected at once?
Surgeries involving multiple toes are commonly performed in a single procedure — correcting the most symptomatic 2nd, 3rd, and 4th toe deformities simultaneously minimizes recovery time compared to staged procedures. The surgical shoe period is the same whether 1 or 3 toes are corrected. Dr. Biernacki plans the surgical approach based on which toes are symptomatic and whether simultaneous bunionectomy is appropriate.
