Age Group	Typical Presentation	Management
Infants (0–2 years)	Toe curls under; parents notice	Observation; usually resolves spontaneously
Toddlers (2–4 years)	Same; may have mild callus forming	Taping + observation; podiatry review annually
School age (4–10 years)	Not resolved; may cause shoe difficulty or pain	Surgical flexor tenotomy if symptomatic; high success
Adolescents / Adults	Rigid curly toe; callosities; shoe fitting issues	Surgery likely needed; flexor tenotomy ± arthrodesis if rigid

Quick answer: Curly Toe is a common foot/ankle topic that affects many patients. The 2026 evidence-based approach combines proper diagnosis, conservative-first treatment, and escalation only when needed. We treat this regularly at our Howell and Bloomfield Township practices. Call (810) 206-1402.

What Is Curly Toe?

Curly toe (also called flexor digitorum longus tendon tightness or congenital curly toe) is present in approximately 5% of children. The affected toe — most commonly the 3rd, 4th, or 5th — curls under the adjacent toe due to relative shortening of the flexor digitorum longus tendon. It is typically bilateral and may run in families. In infants and young children, the toe often curls most noticeably when weight is applied.

Natural History

Most cases improve spontaneously by age 6–8 as the foot grows and the relative tendon imbalance equalizes. Studies show approximately 25–30% of curly toes improve significantly without treatment. The decision point: if the toe remains symptomatic at age 6–8 (causing skin friction, shoe fitting difficulties, or inter-toe corn formation), intervention is appropriate. Taping and stretching in early childhood occasionally help, but evidence for conservative correction is limited.

Surgical Treatment: Flexor Tenotomy

The standard surgical correction is flexor tenotomy — division of the flexor digitorum longus tendon through a small plantar stab incision. This releases the contracture causing the curl. Performed under local anesthesia (or general in young children) as an outpatient procedure. The toe is straightened and taped for 4–6 weeks post-procedure. Success rates are high (85–90%), with the toe settling into a functional straight or near-straight position as the tendon remodels.

Frequently Asked Questions

Should I treat my child’s curly toe? Watch and wait until age 6–8. If the toe is still curling and causing shoe problems or inter-toe skin breakdown, consult a pediatric podiatrist or pediatric orthopedic surgeon.

Is curly toe painful? In children, usually not — the deformity is flexible and the skin is soft. In adults, curly toe causes corns at the pressure points and shoe fitting difficulties, which become painful. Adult presentations benefit from shoe modification or surgical tenotomy.

Is curly toe the same as hammertoe? No — hammertoe is a dorsal contracture of the proximal interphalangeal joint (toe bends upward at the first joint). Curly toe is a plantar/lateral rotation from flexor tendon tightness. Different anatomy, different mechanism, different treatment.

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.
