Claw Toes

Claw toes refer to a condition in which the toes are constantly bent downward, acquiring an appearance similar to a claw.

Symptoms and causes

Claw toes are a condition in which the toes remain continuously flexed downward, causing the extremity to adopt a claw-like appearance.

It is important to highlight the difference between claw toes and other similar conditions:

Claw toes: affect both joints of the toe. There is hyperextension of the metatarsophalangeal joint (which connects the foot bones to the toes) and flexion of the proximal interphalangeal joint (the joint closest to the foot) and the distal interphalangeal joint (the one closest to the nail).
Mallet toes: only the distal interphalangeal joint remains flexed.
Hammer toes: the proximal interphalangeal joint remains flexed.

Toes with three bones and two joints—that is, all toes except the hallux (big toe)—may be affected by this condition, although it is more common in the second, third, and fourth toes.

The prognosis of claw toes is generally favorable if diagnosed early, as there are various highly effective treatments that restore the foot’s anatomy and initial functionality without complications.

Symptoms

The characteristic symptom of claw toes is joint deformity. As it develops gradually, it may not be evident until some time has passed since the toes began to deviate. During this period, other symptoms may appear, such as:

Calluses.
Corns at the base of the toe.
Thickening of the pulp (the fleshy part of the toe).
Blisters in areas where the toes excessively rub against footwear.
Difficulty extending the toes.
Pain when moving the toes or when pressure is applied.
Difficulty walking.

Causes

Claw toes may originate from various causes. The most notable include:

Inappropriate footwear: high-heeled shoes, very tight shoes, or shoes with a narrow toe box that compress the toes and may cause an imbalance between tendons and foot muscles.
Peripheral neuropathy: damage to the nerves of the feet, which may lead to muscle weakness.
Congenital factors: although uncommon, some cases of claw toes have a hereditary component.

Risk Factors

Factors that increase the risk of developing claw toes include:

Advanced age: muscles and nerves weaken over time.
Nerve injuries in the foot due to surgery, trauma, or disease.
Family history.
Certain chronic diseases that cause degeneration of tendons and joints: diabetes, arthritis, multiple sclerosis.
Alterations in foot anatomy: bunions, flat feet, high-arched feet (pes cavus), valgus feet, or bony malformations.

Complications

Complications of claw toes typically occur when appropriate treatment is not received. The most common include:

Chronic pain.
Fixed rigidity: inability to straighten the toe.
Gait alteration: instability leads to difficulty walking due to reduced propulsive capacity.
Difficulty finding suitable footwear.
Skin lesions due to friction with footwear (blisters, corns, calluses), increasing the risk of infections and ulcers in diabetic patients.

Prevention

The best way to prevent claw toes, although not always possible, is to wear comfortable footwear that does not compress the toes, with a low heel and good support.

What specialist treats claw toes?

Claw toes are managed within the specialties of Podiatry, Traumatology and Orthopedic surgery.

Diagnosis

The diagnosis of claw toes is clinical, as it is based on symptoms and physical examination:

Medical history: initially, the specialist gathers all relevant information regarding the patient’s medical and family history, reported symptoms, lifestyle, and overall health status.
Observation of the appearance of the foot, especially the toes.
Palpation to assess toe flexibility and the presence of pain on الضغط or movement.

To rule out other conditions or identify the underlying cause, additional tests may be performed:

Nerve conduction study and electromyography: used to confirm or rule out nerve damage and, if present, determine the affected nerve. Electrical impulses are applied at specific points of the foot to stimulate the nerves. Electrodes placed on the skin record the activity to measure the time required for nerves to transmit the impulse.
X-rays: provide images of the bony structure of the foot, helping to identify malformations, fractures, or conditions such as arthritis.
Blood tests: provide information about the patient’s health status and are essential for diagnosing diseases such as diabetes or inflammatory processes.

Treatment

Treatment of claw toes varies depending on the severity of each case. A conservative approach is usually initiated, including the following recommendations:

Use of comfortable footwear with a wide toe box and low heel.
Corrective orthoses: help position the toes in their natural alignment, relieving pressure and improving gait.

Toe separators to promote alignment and reduce friction.
Gel protectors to prevent rubbing and the formation of corns.
Pads to elevate the metatarsal area (forefoot) and relieve pressure on the toes.
Splints: usually made of elastic bands that help keep the toes straight.
Specific exercises to stretch the toes or strengthen the muscles involved in toe extension.

Corticosteroid injection: the drug is injected directly into the toe joint to relieve pain and reduce inflammation.
Surgery: considered the last resort when previous treatments have not been effective. The procedure typically involves correcting deformities, lengthening tendons, or repositioning the toes.
