Hammer time? Hammertoes!

Hammertoes are a common condition that is treated by podiatrists. When discussing hammertoes, it is important to discuss exactly which joints of the toes are affected, and how they are misaligned. The picture above depicts the three classic types of hammer digits, each of which has an effect on one or more of the three joints of the little toes on the foot.

In mallet toe, only the distal interphalangeal joint is affected. The interphalangeal joints are the joints within each toe. All of the toes besides the big toe have two interphalangeal joints. The big toe has one. Mallet toe is characterized by a toe that is straight until the last “knuckle” joint of the toe, where it is pointed downwards.

In claw toe, all three of the joints of the lesser digits are affected. The metatarsophalangeal joint, the joint that connects the toe to the forefoot, is deviated upwards, while the two interphalangeal joints are deviated downwards. This creates a claw-like appearance, as is seen in the bottom diagram of the drawing.

The most common form of hammer digits is depicted in the middle diagram. This is the classic form of hammertoes. In this form, the metatarsophalangeal joint is deviated upwards, the proximal interphalangeal joint (the one closer to the middle of the foot) is deviated downwards, and the distal interphalangeal joint (the one further down the toe) may be either normal or deviated slightly upwards.

Besides the aesthetic changes to the toes, hammertoes can be a source of pain for many people. When the joints of the toe are misaligned, it forces the toes to take up more space in a shoe. This can often lead to corns on the tops of the toes, as they are rubbing against the top of a shoe.

Additionally, hammertoes are often pointed towards each other, which cause the toes themselves to rub against the other toes. This can also cause corns and calluses to form, as well as abrasions in between the toes.

Hammertoes are caused by a loss of muscle stability and balance that is formed by the muscles of the foot. The flexors on the back of the leg and the extensors on the front of the leg serve to counterbalance each other on the toes, thereby keeping the toes straight. When the balance is lost from things like loss of function of one muscle or strengthening of another muscle, the toes can become deformed. This problem is often seen in women who wear high heeled shoes.

When treating hammertoes, claw toes, or mallet toes, a podiatrist may use one of two approaches. The conservative approach would be to treat the corns and calluses formed by the toes rubbing against either each other or the shoe. This may be done by burning or shaving off the dead skin causing the pain, as well as modifying the shoe gear to accommodate the misaligned toes.

The other route is to correct the misalignment of the toes through surgery. Several different methods are used depending on the extent of the deformity – only your surgeon will be able to decide which the proper method to use is.
