Hammer Toe
.
In this condition, the involved toe is in a fixed, contracted position at the proximal interphalangeal joint. The toe, being higher in the shoe than normal, is exposed to excessive friction, often resulting in a painful heloma. In severe cases, the lesion may become inflamed and ulcerated, leading to secondary bacterial infection and ambulatory disability.

Treatment consists of supporting the transverse arch just behind the metatarsal heads.  The orthotic works in much the same mannor as in metatarsalgia.  Surgical correction, ranging from simple tenotomy to arthroplasty of the digit, should be considered in severe cases.
