Hammertoe: Why Toes Bend and How to Manage It
A hammertoe is a toe bent permanently at the middle joint, leaving a raised, hammer-like shape. Caught early while still flexible, it can often be managed without surgery.
What a hammertoe is
A hammertoe involves an abnormal bend at the proximal interphalangeal joint, most often the second toe. Related deformities include mallet toe (bend at the end joint) and claw toe (bend at multiple joints). Over time a flexible bend can stiffen into a fixed one as the tendons and joint capsule tighten.
Causes
The usual cause is muscle and tendon imbalance, frequently driven by years of tight, pointed or high-heeled shoes that crowd the toes. Bunions, high arches, nerve conditions and previous toe injury also contribute. Genetics play a role in foot structure.
Flexible vs rigid
A flexible hammertoe can still be straightened by hand and responds well to conservative care. A rigid hammertoe will not straighten and the joint has effectively fused in the bent position; corns and calluses often form where the raised joint rubs the shoe. Testing flexibility is the key step a podiatrist uses to choose treatment.
Treatment options
For flexible hammertoes: wear shoes with a deep, roomy toe box, use toe splints or crests, do toe-stretching and towel-curl exercises, and pad any corns. The American Podiatric Medical Association (APMA) recommends footwear changes as the foundation of care. Rigid hammertoes that cause pain or ulceration may need surgical correction to release tendons or realign the joint.
Prevention
Choose shoes with at least a thumb's width of space beyond the longest toe, avoid prolonged high heels, and keep foot muscles strong with regular toe exercises. Early attention while the toe is still flexible gives the best outcome.
Frequently asked questions
- Can hammertoes be fixed without surgery?
- Flexible hammertoes often improve with roomy shoes, splints and exercises. Rigid ones usually need surgery to straighten.
- Do toe straighteners work?
- They can relieve pressure and slow progression in flexible hammertoes but will not permanently correct a rigid joint.
