Overview
A hammertoes is a contracture Hammer toes of the toes as a result of a muscle imbalance between the tendons on the top and the tendons on the bottom of the toe. They can be flexible or rigid in nature. When they are rigid, it is not possible to straighten the toe out by manipulating it. Frequently, they develop corns on the top of the toe as a result of rubbing on the shoe. They may also cause a bothersome callous on the ball of the foot. This occurs as a result of the toe pressing downward on the bone behind the toe. This area then becomes prominent and the pressure of the bone against the ground causes a callous to form.
Causes
Flat feet can result in hammertoes, this is due to poor mechanics off the foot. High arched feet can also result in buckling toes. A major cause is in hereditary, all the toe conditions mentioned could be acquired due in hereditary factors. Bunions are a major cause of hammertoes. Claw toes are usually the result of a shoe that is too short. For many people, the second toe is actually longer than the great toe, and if shoes are sized to fit the great toe, the second (and maybe even the third toe) will have to bend to fit into the shoe. Shoes that are pointed make matters even worse. Combine pointed shoes with high heels, the foot is under similar pressure as if it was constantly being pushed downhill into a wall. Rheumatoid arthritis can also lead to bunions, which in turn can lead to hammer toes.
Symptoms
Symptoms of a hammertoe are usually first noticed as a corn on the top of the toe or at the tip which produces pain with walking or wearing tight shoes. Most people feel a corn is due to a skin problem on their toes, which in fact, it is protecting the underlying bone deformity. A corn on the toe is sometimes referred to as a heloma dura or heloma durum, meaning hard corn. This is most common at the level of the affected joint due to continuous friction of the deformity against your shoes.
Diagnosis
First push up on the bottom of the metatarsal head associated with the affected toe and see if the toe straightens out. If it does, then an orthotic could correct the problem, usually with a metatarsal pad. If the toe does not straighten out when the metatarsal head is pushed up, then that indicates that contracture in the capsule and ligaments (capsule contracts because the joint was in the wrong position for too long) of the MTP joint has set in and surgery is required. Orthotics are generally required post-surgically.
Non Surgical Treatment
Early on, when a hammertoe first starts and is still flexible, here are some ways it might be treated. Your healthcare provider may splint or tape the toe into the correct, normal position. You can use your fingers to stretch your toes and toe joints toward a more normal position. Exercise your toes by trying to pick up marbles with them or by wadding up a towel on the floor with your toes. Padding may be used to change where your weight falls when you walk on the foot.
Surgical Treatment
Probably the most frequent procedure performed is one called a Post or an Arthroplasty. In this case a small piece of bone is removed from the joint to straighten the toe. The toe is shortened somewhat, but there is still motion within the toe post-operatively. In other cases, an Arthrodesis is performed. This involves fusing the abnormally-contracted joint. The Taylor procedure fuses only the first joint in the toe, whereas the Lambrinudi procedure fuses both joints within the toe. Toes which have had these procedures are usually perfectly straight, but they take longer to heal and don't bend afterwards. A Hibbs procedure is a transfer of the toe's long extensor tendon to the top of the metatarsal bone. The idea of this procedure is to remove the deforming cause of the hammertoes (in this case, extensor substitution), but to preserve the tendon's function in dorsifexing the foot by reattaching it to the metatarsals. Fortunately, the Gotch (or Gotch and Kreuz) procedure--the removal of the base of the toe where it attaches to the foot, is done less frequently than in years past. The problem with this procedure is that it doesn't address the problem at the level of the deformity, and it causes the toe to become destabilized, often resulting in a toe that has contracted up and back onto the top of the foot. You can even have an Implant Arthroplasty procedure, where a small, false joint is inserted into place. There are several other procedures, as well.
Prevention
Certain exercises such as moving and stretching your toe gently with your hands and picking up small or soft objects such as marbles or towels can keep your toe joints flexible, simple exercises can stretch and strengthen your muscles. Limit high-heel use, well-designed flat shoes will be more comfortable than high heels. Don't wear shoes that are too short or too narrow, or too shallow, this is especially important for children going through periods of rapid growth, the toe area should be high enough so that it doesn't rub against the top of your toes.
