A Hammer toe is a toe that is bent because of a muscle imbalance around the toe joints. The imbalance causes the toe to bend at one or more joints, pushing the middle of the toe upward in a claw-like position. If you notice such changes, it is important to seek proper treatment. Hammer toes never get better without some type of intervention and the sooner it is treated, the better the outcome.
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.
Hammer toes can cause problems with walking and lead to other foot problems, such as blisters, calluses, and sores. Pain is caused by constant friction over the top of the toe?s main joint. It may be difficult to fit into some shoe gear due to the extra space required for the deformed toe. In many cases there will be pain on the ball of the foot over the metatarsals along with callus formation. This is due to the toes not functioning properly, failing to properly touch the ground during the gait cycle. The ball of the foot then takes the brunt of the ground forces, which causes chronic pain.
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
A number of approaches can be undertaken to the manage a hammer toe. It is important that any footwear advice is followed. The correct amount of space in the toe box will allow room for the toes to function hammertoes without excessive pressure. If a corn is present, this will need to be treated. If the toe is still flexible, it may be possible to use splints or tape to try and correct the toe. Without correct fitting footwear, this is often unsuccessful. Padding is often used to get pressure off the toe to help the symptoms. If conservative treatment is unsuccessful at helping the symptoms, surgery is often a good option.
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.
