The term, hammertoe is used to describe the collective physical deformity of the second, third and fourth toe on a person's foot when they are permanently bent at one or two of their joints, often times at their middle joints or, 'proximal interphalangeal,' joints. The condition is also referred to as, 'contracted toes,' and earned its name for the resulting bowed appearance of the toes that made them appear similar to hammers. The distortion of the usual contour of the person's toes is usually a result of wearing shoes that are too short or narrow and apply consistent pressure to the toes, forcing them to be pushed together and lie obliquely. The situation is particularly true in the case of shoes that are designed to narrow towards the toe box.
A common cause of hammertoe and mallet toe is wearing improper footwear - shoes that are too tight in the toe box, or high-heel shoes. Wearing shoes of either type can push your toes forward, crowding one or more of them into a space that's not large enough to allow your toes to lie flat. Hammertoe and mallet toe deformities can also be inherited and may occur despite wearing appropriate footwear. The result is a toe that bends upward in the middle and then curls down in a hammer-like or claw-like shape. Your shoes can rub against the raised portion of the toe or toes, causing painful corns or calluses. The bottom of the affected toe can press down, creating the mallet-like appearance of mallet toe. At first, a hammertoe or mallet toe may maintain its flexibility and lie flat when you're not wearing crowded footwear. But eventually, the tendons of the toe may contract and tighten, causing your toe to become permanently stiff.
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.
Hammer toes may be easily detected through observation. The malformation of the person's toes begin as mild distortions, yet may worsen over time - especially if the factors causing the hammer toes are not eased or removed. If the condition is paid attention to early enough, the person's toes may not be permanently damaged and may be treated without having to receive surgical intervention. If the person's toes remain untreated for too long, however the muscles within the toes might stiffen even more and will require invasive procedures to correct the deformity.
Non Surgical Treatment
Treatment for a hammertoe usually depends on the stage of hammertoe the hammertoe and the cause of the condition. If your toe is still bendable, your doctor may suggest conservative care-relieving pressure with padding and strapping, or proper shoes that have a deep toe box and are of adequate length and width. Early intervention can often prevent the need for surgery.
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.
