Toe deformities (hammer, claw, curly, mallet toe and overriding of toes) are unknown in non-shoe wearing populations. Their incidence varies from 2 to 20%, and increases with age. Women are affected four to five times more often than men.
Most people have no underlying disease, although neuromuscular diseases and inflammatory arthropathies may be accompanied by such toe deformities.
Toe deformities are more common in people with diabetes, due to muscle atrophy and limited joint mobility. Deformities such as those described above, when present in a patient with loss of sensation due to diabetic neuropathy, pose a risk for the development of neuropathic ulcers, as prominences are susceptible to skin-on-shoe friction. Patients are instructed to check their feet every day. Shoes with a high toe box protect the deformed toes from ulceration.
