The name Hammertoes
comes from the way the tip of the toe hits or hammers on the floor with each step. The primary deformity seen in a hammer toe is found at the PIPJ (proximal interphalangeal joint) which is the first or more proximal of the two joints of the toe. A mallet toe, on the other hand, is a similar deformity but is found in the DIPJ (distal interphalangeal joint). And lastly, claw toes are a deformity where the entire toe grabs and involves the MPJ (metatarsal phalangeal joint) PIPJ and DIPJ. Collectively, these deformities are referred to as hammer toes. Hammer toes can affect one or all of the toes simultaneously.
The main cause of hammer toe is poorly fitted and/or poorly designed footwear. Any footwear that is too tight in the toe box, especially high-heeled shoes, can push the toes forward, crowding one or more of them into a space that is not large enough to allow the toes to lie flat and spread as they should. Other causes include the following. Changes in foot anatomy. Sometimes the metatarsal bones in the ball of the foot can ?drop,? creating a situation in which the toes do not make contact with the surface of the shoe. The toes may then contract at one or both of the joints to re-establish contact with the surface. Traumatic injuries in which toes are jammed or broken. Diabetic neuropathy. This can cause abnormal foot biomechanics due to nerve and/or muscle damage. Damage to nerves and muscles from other conditions, such as arthritis or stroke. Heredity.
The symptoms of a hammer toe include the following. Pain at the top of the bent toe upon pressure from footwear. Formation of corns on the top of the joint. Redness and swelling at the joint contracture. Restricted or painful motion of the toe joint. Pain in the ball of the foot at the base of the affected toe.
A hammertoe is usually diagnosed with a physical inspection of your toe. Imaging tests, such as X-rays, may be ordered if you have had a bone, muscle, or ligament injury in your toe.
Non Surgical Treatment
Non-surgical methods for hammer toes (claw toes) are aimed at decreasing symptoms (i.e., pain and/or calluses) and/or limiting the progression into a larger problem. Simple treatments patients can do are wear supportive shoes. Use an arch support. Wear shoes with a wide toe box. Modify activities. Spot stretch shoes. Periodic callus care.
If these treatments are not sufficient at correcting the hammer toe, an operation to straighten the toe may be necessary. This is often performed in conjunction with surgery for a bunion deformity. The surgical treatment of a hammer toe can consist of either cutting the tendons to relieve the pressure that causes the deformity, or fusing the toe so that it points straight permanently.
