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.
Hammertoes are a contracture of the toes as a result of a muscle imbalance between the tendons on the top of the toes (extensor tendons) and the tendons on the bottom of the toes (flexor tendons). If
there is an imbalance in the foot muscles that stabilize the toe, the smaller muscles can be overpowered by the larger flexor and extensor muscles.
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.
The treatment options vary with the type and severity of each hammer toe, although identifying the deformity early in its development is important to avoid surgery. Your podiatric physician will
examine and X-ray the affected area and recommend a treatment plan specific to your condition.
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 corns (clavi, helomata) by a podiatrist can provide temporary relief. Corticosteroid
injections are often very effective in reducing pain.
If conservative treatments fail and your symptoms persist, the doctor may recommend a surgical option to straighten the toe. The procedures used vary greatly, depending upon the reasons for the
hammertoe. There are a number of different operations to correct hammertoes, the most common ones involve Soft tissue corrections such as tendon transfers, tendon lengthening, and joint capsule
repairs. Digital arthroplasty involves removal of bone from the bent joint to allow the toe to straighten. The temporary use of pins or K-wires may be necessary to keep the toe straight during the
healing period. Joint implants are sometimes used to allow for a better range of motion in the toe following surgery. Digital arthrodesis involves the removal of bone from the bent joint and fusing
the toe in a straight position. If the corn is due to a bone spur, the most common procedure used is an exostectomy, in which surgically removing it or filing it down removes the bone spur. Because
of the possible complications involved with any surgery, one should be sure to understand the risks that may be involved with surgery to correct hammertoes and remove bone spurs.
