OverviewHammertoes 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.
Causes
Claw, hammer and mallet toe are most commonly caused by wearing high heels or ill-fitting shoes that are too tight e.g. narrow toebox. If shoes like this are worn for long periods, the foot is held in a slightly bent position and gradually over time, the muscles tighten and shorten. If this continues for long enough, then the muscles become so tight that even when shoes are removed, the toe is still held in the bent position. Another common cause is Morton?s Toe, where the second toe is longer than the big toe. In this case, the second toe is commonly squashed into a shoe into an unnaturally bent position.
Symptoms
The most obvious symptom of hammer, claw or mallet toe is the abnormal toe position. This is usually combined with pain: the abnormal foot position leads to excessive friction on the toe as it rubs against any footwear which can be extremely painful. Corns & Calluses: repeated friction can result in the formation of a foot corn or callus on top of the toes. Stiffness, the joints become increasingly stiff. In the early stages, the toes can usually be straightened out passively using your hands, but if allowed to progress, the stiffness may be permanent.
Diagnosis
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
You can usually use over-the-counter cushions, pads, or medications to treat bunions and corns. However, if they are painful or if they have caused your toes to become deformed, your doctor may opt to surgically remove them. If you have blisters on your toes, do not pop them. Popping blisters can cause pain and infection. Use over-the-counter creams and cushions to relieve pain and keep blisters from rubbing against the inside of your shoes. Gently stretching your toes can also help relieve pain and reposition the affected toe.
Surgical Treatment
Surgery to correct for a hammertoe may be performed as an outpatient procedure at a hospital, surgery center, or in the office of your podiatrist. There are multiple procedures that can be used depending on your individual foot structure and whether the deformity is flexible or rigid. There may be a surgical cut in the bone to get rid of an exostosis, or a joint may be completely removed to allow the toe to lay straight.
