Lesser Toe Deformities and Surgical Correction

Overview

Hammertoe, claw toe, mallet toe and crossover toe describe different patterns of lesser-toe deformity. Symptoms usually come from shoe pressure, painful callus, instability or overload beneath the ball of the foot. Treatment should address the painful structure and how pressure is distributed across the forefoot, not the appearance of one toe alone. Surgery is considered when appropriate footwear and pressure-relief measures no longer provide acceptable comfort or function.

Types of deformity

  • Hammertoe: bending mainly at the middle toe joint, often with the joint where the toe meets the foot pulled upwards.
  • Claw toe: extension at the base of the toe with bending at both smaller toe joints.
  • Mallet toe: bending mainly at the joint nearest the tip of the toe.
  • Crossover or unstable toe: the toe drifts sideways or upwards, commonly because the plantar plate—a strong supporting structure beneath the joint where the toe meets the foot—and nearby ligaments are damaged.

Why do lesser toes deform?

Contributing factors include hallux valgus, a relatively long metatarsal, plantar-plate injury, tendon imbalance, high-arched or flatfoot alignment, inflammatory arthritis, nerve or muscle disease and previous trauma. Tight shoes can aggravate pressure but are not the only cause.

Assessment includes whether the toe is flexible, areas of callus, stability at the base of the toe, the position of the big toe, forefoot loading and the shape of the entire foot. Weight-bearing X-rays are often used when surgery is being considered.

Non-surgical treatment

  • Shoes with a wide and deep toe box and soft upper material.
  • Silicone sleeves, pads, taping or splints when they reduce pressure without creating new rubbing or skin damage.
  • Callus care and pressure redistribution with an insole or metatarsal pad.
  • Stretching and strengthening when the deformity is flexible, although exercises do not usually straighten a fixed deformity.
  • Management of associated bunion, inflammatory disease, diabetes or nerve problems.

When may surgery be considered?

Surgery may be discussed when pain, threatened skin, recurrent infection, shoe conflict or functional difficulty remains unacceptable despite reasonable footwear and pressure-relief measures. Cosmetic correction of a painless toe is not recommended.

The procedure must address the joints, tendons and instability responsible for the deformity. Straightening one toe without considering a bunion or abnormal forefoot load can leave persistent symptoms or contribute to recurrence.

What may correction involve?

A flexible deformity may be treated by balancing, releasing or transferring tendons. A fixed deformity often requires removal of a small amount of bone and fusion or resection of the affected toe joint. Instability where the toe joins the foot may require repair of the plantar plate, soft-tissue balancing and sometimes controlled shortening of a metatarsal.

The toe may be held with a temporary wire, internal implant or suture construct. A bunion or metatarsal procedure may be performed at the same operation when it is needed to correct instability, deformity or the source of overload.

Recovery

A postoperative shoe is commonly used, with weight-bearing instructions based on the procedures performed. Swelling and stiffness are expected and may persist for months. A temporary wire, when used, remains outside or beneath the skin for a defined period and requires protection.

Dressings may help maintain alignment. Return to normal shoes, driving, work and sport depends on wound healing, swelling, fixation and the extent of combined forefoot surgery.

Risks and limitations

  • Infection, wound problems or pin-site infection.
  • Numbness, painful scar or injury to the blood supply of a toe.
  • Stiffness, swelling, residual pain or a toe that feels different from normal.
  • Recurrence, over-correction, or a toe that floats or no longer rests firmly on the ground.
  • Delayed or failed bone healing, or irritation from an implant.
  • Transfer pain beneath another metatarsal.
  • Need for further surgery. In a high-risk foot, severe infection or loss of blood supply can very rarely threaten the toe.

Frequently asked questions

Pressure and pain can often be managed with footwear and padding. A fixed adult deformity usually cannot be permanently straightened without surgery.

The aim is a straighter, more comfortable and shoe-tolerant toe. Some stiffness, swelling or altered sensation is common.

When the toe joint is unstable or overloaded, a controlled bone cut can shorten the long bone behind the toe (metatarsal), reduce pressure and help realign the toe.

No. Fixation depends on the deformity and procedure. A temporary wire, buried implant or no rigid fixation may be appropriate.

Yes. Recurrence may occur because of soft-tissue imbalance, associated bunion or foot shape, healing and progression over time.
