Hammertoe Causes Stages & Treatment 2026 | DPM

Stage	Joint Status	Manual Reducibility	Corns / Callus	Treatment
Stage 1 (Flexible)	Passively correctable	Full reduction manually	Mild dorsal corn over PIP	Toe splint; orthotics; shoe modification
Stage 2 (Semi-Rigid)	Partially correctable	Partial reduction; resistance	Established corn; MTP synovitis	Orthotics + cortisone; surgical planning
Stage 3 (Rigid)	Fixed contracture	Cannot be reduced	Painful corn; possible ulceration	PIP arthroplasty or arthrodesis

Cause	Mechanism	Most Common Toe	Associated Finding
Ill-fitting footwear	Toe forced into flexion; imbalance of extrinsic/intrinsic muscles	2nd toe most common	Hallux valgus often coexists
Bunion (Hallux Valgus)	1st toe deviates laterally; pushes 2nd toe into crossover/hammertoe	2nd toe crossover	Positive too-many-toes sign
Neuromuscular Disease	Intrinsic muscle weakness; Charcot-Marie-Tooth	Multiple toes	Cavus foot; bilateral deformity
Trauma	MTP joint injury; plantar plate disruption	2nd or 3rd	Swelling, joint laxity
Rheumatoid Arthritis	MTP joint destruction; tendon and capsule disruption	Multiple toes	MTP subluxation; wind-swept deformity
Intrinsic Minus Foot	Lumbrical weakness; clawing of all lesser toes	All lesser toes	High arch; diabetic neuropathy common

Quick answer: Treatment for hammertoe causes stages treatment surgery follows a stepwise approach: 1) conservative care first (rest, ice, supportive footwear, OTC anti-inflammatories), 2) physical therapy and targeted exercises, 3) in-office treatments (injections, custom orthotics) if conservative fails at 4-6 weeks, 4) surgery for refractory cases. Most patients resolve at step 1 or 2. Call (810) 206-1402.

What Is a Hammertoe?

A hammertoe is a flexion deformity of the proximal interphalangeal (PIP) joint of the lesser toes — the toe bends downward at the first joint from the base, creating a hammer-like appearance. It most commonly affects the second toe, though it can occur in any lesser digit. A related deformity, claw toe, involves flexion at both the PIP and distal interphalangeal (DIP) joints.

Causes and Risk Factors

Hammertoe develops from muscle imbalance between the intrinsic foot muscles (which straighten the toe) and the extrinsic flexors (which flex the toe). Contributing factors include shoes with a narrow toe box that chronically compress the toes into flexion, bunion deformity that pushes the second toe into an abnormal position, flat feet that alter toe muscle mechanics, and inherited toe length discrepancies (a second toe longer than the first — Morton’s foot).

Flexible vs. Rigid Classification

The most clinically important distinction is between flexible and rigid hammertoe. A flexible hammertoe can be straightened manually to a neutral position — the joint remains mobile. Conservative care can prevent progression. A rigid hammertoe is fixed in the deformed position — the joint has contracted and cannot be passively corrected. Conservative care manages symptoms but cannot correct the deformity; surgery is required for correction.

Conservative Treatment

Conservative management addresses footwear, padding, and toe mechanics. Wide toe box shoes and open-toed footwear reduce compression. Hammer toe splints and silicone toe cushions reduce friction at the prominent PIP joint and plantar plate. Metatarsal pads reduce pressure beneath the metatarsal heads. Custom orthotics may address the underlying flat foot or forefoot imbalance contributing to the deformity. Conservative care is appropriate for flexible hammertoe and for symptom management in rigid cases where surgery is not desired.

Surgical Treatment

Surgical correction is appropriate for rigid hammertoes with pain, skin breakdown, or significant functional limitation. Flexible hammertoes may be treated surgically when conservative care fails. Proximal interphalangeal arthroplasty (PIP arthroplasty) involves partial resection of the joint and realignment — maintaining some joint motion. PIP arthrodesis (fusion) fuses the joint in a straightened position — the preferred procedure for rigid deformities, providing durable correction. K-wire or smart-toe implant fixation maintains alignment during healing. Recovery to regular footwear takes 6-12 weeks.
