Hammertoes are another forefoot deformity that can take a walker out of their activity. A Hammer toe generally represent a tendon imbalance in the toes caused by one of the toe tendons getting an advantage over another toe tendon. Most commonly, it is one or all of the long extensor tendons on the top of the foot that gets an advantage over one or all of the flexor tendons on the bottom of the foot, to cause the first joint in the toe to be elevated above the ground. Most shoe wearing people chronically alter the delicate balance that co-exists amongst the toe tendons whether they know it or not.
Hammertoe is caused when muscles fail to work in a balanced manner and the toe joints bend to form the hammertoe shape. If they remain in this position, the muscles and tendons hammertoe supporting them tighten and stay that way. Causes of hammertoe can include squeezing into a too-small or ill-fitting shoe or wearing high heels that jam your toes into a tight toe box. An injury such as badly stubbing your toe. Arthritis. Nerve and muscle damage from diseases such as diabetes,
A toe (usually the second digit, next to the big toe) bent at the middle joint and clenched into a painful, clawlike position. As the toe points downward, the middle joint may protrude upward. A toe with an end joint that curls under itself. Painful calluses or corns. Redness or a painful corn on top of the bent joint or at the tip of the affected toe, because of persistent rubbing against shoes Pain in the toes that interferes with walking, jogging, dancing, and other normal activities, possibly leading to gait changes.
Your doctor is very likely to be able to diagnose your hammertoe simply by examining your foot. Even before that, he or she will probably ask about your family and personal medical history and evaluate your gait as you walk and the types of shoes you wear. You'll be asked about your symptoms, when they started and when they occur. You may also be asked to flex your toe so that your doctor can get an idea of your range of motion. He or she may order x-rays in order to better define your deformity.
Non Surgical Treatment
Symptomatic treatment of hammertoes consists of such things as open toed shoes or hammertoe pads. There are over the counter corn removers for temporally reducing the painful callous often seen with the hammertoe. These medications must be used with caution. They are a mild acid that burns the callous off. These medications should never be used for corns or callouses between the toes. Persons with diabetes or bad circulation should never use these products.
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.
Although there is little doubt shoes are responsible for causing corns, the size, shape and other characteristics of our feet are hereditary. A severe bunion may cause a hammertoe, as the great toe twists over or under the second toe, causing it to dislocate.
