Could Hammer Toes Cause Neuropathy

Overview

A Hammer toes or contracted toe is a deformity of the proximal interphalangeal joint of the second, third, or fourth toe causing it to be permanently bent, resembling a hammer. Mallet toe is a similar condition affecting the distal interphalangeal joint. Claw toe is another similar condition, with dorsiflexion of the proximal phalanx on the lesser metatarsophalangeal joint, combined with flexion of both the proximal and distal interphalangeal joints. Claw toe can affect the second, third, fourth, or fifth toes.

Causes

Footwear can contribute significantly to the development of hammertoes. Shoes that are too small force your toes into a curled position. Over time, your toe tendons adjust to this positioning, causing your toe or toes to hold a hammered shape. Athletes may be especially susceptible, because of the increased forces on the toes from shoes that are too small or tight. Heel elevation in footwear is also problematic, as it causes your toes to be pushed into the shoe?s toe box. Heel elevation additionally contributes to muscle imbalance. A common example of this is when your Achilles tendon-the tendon at the back of your leg that attaches your calf muscles to your heel bone-is too tight, causing the tendons on the top of your foot that attach to your toes to work too hard and hold your toes in an unnatural, elevated position.

Symptoms

Symptoms include sharp pain in the middle of the toe and difficulty straightening the toe. People with hammertoe may also develop blisters, which are fluid-filled pockets of skin, because the bent toe is likely to rub against the inside of a shoe. This increased friction may also lead to calluses, which are areas of thickened skin, and corns, which are hard lumps that may form on or between toes. Symptoms may be minor at first, but they can worsen over time.

Diagnosis

Although hammertoes are readily apparent, to arrive at a diagnosis the foot and ankle surgeon will obtain a thorough history of your symptoms and examine your foot. During the physical examination, the doctor may attempt to reproduce your symptoms by manipulating your foot and will study the contractures of the toes. In addition, the foot and ankle surgeon may take x-rays to determine the degree of the deformities and assess any changes that may have occurred.

Non Surgical Treatment

There are many non-surgical treatments to help relieve symptoms of hammertoe. The first step for many people is wearing the right size and type of shoe. Low-heeled shoes with a boxy or roomy toe area are helpful. Cushioned insoles, customized orthopedic inserts, and pads can provided relief as well. Splints or straps may be used to help correct toe position. Your doctor may show you toe stretches and exercises to perform. Your doctor can safely remove corns and calluses. You should not try to remove them at home.

Surgical Treatment

Laser surgery is popular for cosmetic procedures, however, for hammer toe surgery it does not offer any advantage to traditional methods. Laser is useful for soft tissues (not bone), and because hammer toe surgery involves bone procedures, it is not effective. For cosmetic hammer toe surgery, patients should look hammertoe for surgeons experienced in aesthetic foot surgery.

Prevention

Although the feet naturally change over time, and abnormalities like hammertoes may be hereditary for some patients, steps may be taken to prevent their development in the first place. Just as better fitting shoes are a treatment, they are also a preventative measure for hammertoes. In addition, your podiatrist may suggest orthotics to improve the biomechanics of your feet in an effort to prevent the development of hammertoes or other abnormalities. Calf stretching and other exercises may also be used to reverse or treat muscle imbalances that could eventually lead to hammertoe development.
