Claw Toe

What claw toe looks like

Each small toe has three joints: the metatarsophalangeal (MTP) joint at the base, the proximal interphalangeal (PIP) joint in the middle and the distal interphalangeal (DIP) joint near the tip. In claw toe:

• the MTP joint bends up (extends)
• the PIP and DIP joints bend down (flex)
• the toe tip may press into the ground or the sole of the shoe

Claw toe vs hammer toe vs mallet toe

Claw toes more often affect several toes and both feet, and are more often linked to nerve or muscle disease.

Symptoms

• toes curled into a claw shape
• corns on the top of the bent middle joints, where they rub on shoes
• corns on the tips of the toes
• painful calluses under the ball of the foot, because the raised toe pushes the metatarsal head downward
• pain in the ball of the foot (metatarsalgia)
• difficulty finding comfortable shoes
• stiffness as the deformity becomes fixed

Causes

The small muscles inside the foot normally keep the toes straight. When they weaken, or when the long toe muscles in the leg overpower them, the toes claw.

• Footwear: narrow, tight or high-heeled shoes cramp the toes.
• High arches (pes cavus): often linked to clawing.
• Nerve damage: diabetic neuropathy, alcohol-related neuropathy, Charcot-Marie-Tooth disease, spinal cord problems, stroke, cerebral palsy, multiple sclerosis.
• Inflammatory arthritis: rheumatoid arthritis damages the joints and ligaments at the base of the toes.
• Injury: ankle fractures, compartment syndrome of the leg or foot, and burns can cause clawing.
• Aging and genetics.

Diagnosis

A doctor or podiatrist examines the toes standing and sitting, checks whether the deformity is flexible or rigid, looks for corns, calluses and ulcers, and tests sensation, reflexes, strength and pulses. Weight-bearing X-rays show joint position and arthritis. Nerve conduction studies or blood tests may be done if a neurological cause is suspected, particularly when both feet develop claw toes.

Treatment

Non-surgical

• Footwear: shoes with a deep, wide toe box, soft uppers and low heels; avoid pointed toes and high heels.
• Padding: gel toe sleeves, corn pads and silicone toe props.
• Insoles: metatarsal pads or custom orthotics to offload the ball of the foot.
• Exercises for flexible claw toes: picking up marbles or a towel with the toes, toe spreading, and gently straightening the toes by hand several times a day.
• Taping or splints to hold flexible toes straight.
• Podiatry care: regular trimming of corns and calluses. People with diabetes should not cut corns themselves.

Surgery

Surgery is considered when pain persists despite these measures, or when ulcers keep forming. Options depend on flexibility:

• Flexible claw toes: tendon transfer or release, rerouting the long toe-bending tendon to straighten the toe.
• Rigid claw toes: fusion or removal of part of the PIP joint, often held with a temporary wire, plus release of the MTP joint.
• Metatarsal surgery if the ball of the foot is overloaded.
• Correction of underlying high arches in some people.

Recovery typically involves a surgical shoe for about 4 to 6 weeks, with swelling lasting several months.

Complications

• painful corns and calluses
• skin breakdown and ulcers, especially with diabetes or neuropathy
• infection of ulcers, which can reach bone
• falls from altered foot mechanics

Prevention

• wear shoes that fit, with space for the toes
• check feet daily if you have diabetes or neuropathy
• stretch and strengthen the foot muscles
• treat underlying conditions early

Frequently asked questions

What causes claw toe?

Claw toe results from an imbalance between the small muscles in the foot and the long toe muscles, so the toes curl. Causes include tight or high-heeled shoes, high arches, nerve damage from diabetes or other conditions, rheumatoid arthritis, stroke and injury.

What is the difference between claw toe and hammer toe?

In claw toe, the toe bends up at the base and down at both the middle and end joints. In hammer toe, the toe bends down mainly at the middle joint, with the tip often pointing up or straight. Claw toes more often affect several toes and are linked to nerve problems.

Can claw toes be fixed without surgery?

Flexible claw toes often improve or stop progressing with roomy shoes, padding, insoles, taping and toe exercises. Rigid claw toes do not straighten without surgery, but pain can often be controlled with footwear changes and podiatry care.

Is claw toe a sign of diabetes?

It can be. Diabetic neuropathy weakens the small foot muscles and is a common cause of claw toes. People with diabetes and claw toes are at higher risk of ulcers, so regular foot checks and proper footwear are especially important.

How long does recovery from claw toe surgery take?

Most people wear a protective surgical shoe for about 4 to 6 weeks, and any wire is removed during that time. Swelling can last 3 to 6 months. Return to normal shoes and activities depends on the procedure and healing.
