Hammer toes is a Z-shaped deformity caused by dorsal subluxation at the metatarsophalangeal joint. Diagnosis is clinical. Treatment is modification of footwear and/or orthotics. The usual cause is misalignment of the joint surfaces due to a genetic predisposition toward aberrant foot biomechanics and tendon contractures. RA and neurologic disorders such as Charcot-Marie-Tooth disease are other causes.
The main cause of hammer toe is poorly fitted and/or poorly designed footwear. Any footwear that is too tight in the toe box, especially high-heeled shoes, can push the toes forward, crowding one or more of them into a space that is not large enough to allow the toes to lie flat and spread as they should. Other causes include the following. Changes in foot anatomy. Sometimes the metatarsal bones in the ball of the foot can ?drop,? creating a situation in which the toes do not make contact with the surface of the shoe. The toes may then contract at one or both of the joints to re-establish contact with the surface. Traumatic injuries in which toes are jammed or broken. Diabetic neuropathy. This can cause abnormal foot biomechanics due to nerve and/or muscle damage. Damage to nerves and muscles from other conditions, such as arthritis or stroke. Heredity.
A hammertoe causes you discomfort when you walk. It can also cause you pain when trying to stretch or move the affected toe or those around it. Hammertoe symptoms may be mild or severe. Mild Symptoms, a toe that is bent downward, corns or calluses. Severe Symptoms, difficulty walking, the inability to flex your foot or wiggle your toes, claw-like toes. See your doctor or podiatrist right away if you develop any of these symptoms.
Hammer toes may be easily detected through observation. The malformation of the person’s toes begin as mild distortions, yet may worsen over time – especially if the factors causing the hammer toes are not eased or removed. If the condition is paid attention to early enough, the person’s toes may not be permanently damaged and may be treated without having to receive surgical intervention. If the person’s toes remain untreated for too long, however the muscles within the toes might stiffen even more and will require invasive procedures to correct the deformity.
Non Surgical Treatment
Hammertoes that are not painful (asymptomatic) and still flexible may not require treatment. In mild cases, open-toed, low-heeled, or wider shoes and foam or moleskin pads can provide symptomatic relief by reducing pressure. Taping (strapping) the affected toe can help to reduce deformity and pain. Physical therapy to instruct patients in exercises that passively stretch tight structures and strengthen weak foot intrinsic muscles is also helpful with mild cases. Periodic trimming (debridement) of Hammer toe corns (clavi, helomata) by a podiatrist can provide temporary relief. Corticosteroid injections are often very effective in reducing pain.
If conservative treatments don’t help, your doctor may recommend surgery to release the tendon that’s preventing your toe from lying flat. In some cases, your doctor might also remove some pieces of bone to straighten your toe.
