A Hammertoe is a deformity of the second, third or fourth toes. In this condition, the toe is bent at the middle joint, so that it resembles a hammer. Initially, hammer toes are flexible and can be corrected with simple measures but, if left untreated, they can become fixed and require surgery. People with hammer toe may have corns or calluses on the top of the middle joint of the toe or on the tip of the toe. They may also feel pain in their toes or feet and have difficulty finding comfortable shoes.
Hammertoes are usually structural in nature. Many times this is the foot structure you were born with and other factors have now made it so that symptoms appear. The muscles in your foot may become unbalanced over time, allowing for a deformity of the small bones in each toe. With longstanding deformity the toe may become rigid. Sometimes one toe is longer than another and this causes a buckling of the digit. A hammertoe may also be caused by other foot deformities such as a bunion. Trauma or other surgery of your foot may predispose you to having the condition if your foot structure is altered.
The symptoms of hammertoe include a curling toe, pain or discomfort in the toes and ball of the foot or the front of the leg, especially when toes are stretched downward. Thickening of the skin above or below the affected toe with the formation of corns or calluses. Difficulty finding shoes that fit well. In its early stages, hammertoe is not obvious. Frequently, hammertoe does not cause any symptoms except for the claw-like toe shape.
Your healthcare provider will examine your foot, checking for redness, swelling, corns, and calluses. Your provider will also measure the flexibility of your toes and test how much feeling you have in your toes. You may have blood tests to check for arthritis, diabetes, and infection.
Non Surgical Treatment
In the early stages, the deformities from mallet toe, claw toe and hammertoe can be corrected. But if treatment is delayed too long, permanent stiffness can ensue which can only be corrected by surgery. The most effective treatment options are good fitting footwear. Shoes with a wide toebox will be more comfortable and will reduce the tension on the muscles and friction on the toes. Avoid high heels as they push your feet forwards to the front of the shoes. This increases the pressure on the toes, forcing them to bend more than usual. Shoes should ideally be half an inch longer than your longest toe. Exercises to strengthen and stretch the muscles can be really helpful. Simple things like trying to pick marbles up with your feet or scrunching up a towel underneath your foot can work well.
Surgical correction is necessary in more severe cases and may consist of removing a bone spur (exostectomy) removing the enlarged bone and straightening the toe (arthroplasty), sometimes with internal fixation using a pin to realign the toe; shortening a long metatarsal bone (osteotomy) fusing the toe joint and then straightening the toe (arthrodesis) or simple tendon lengthening and capsule release in milder, flexible hammertoes (tenotomy and capsulotomy). The procedure chosen depends in part on how flexible the hammertoe is.
