Overview
There are two main types of Hammer toes. Hammertoes can be flexible, which means that you can still move the toe a bit - these are easier to treat with stretching, wider shoes and in some cases, toe splints. Rigid hammertoes occur when the foot condition has persisted for so long without treatment that the tendons become too rigid to be stretched back to normal. Rigid hammertoes are more common in people with arthritis. This foot condition usually needs to be treated with surgery.
Causes
But what causes the imbalance of the tendons and muscles in the first place so that they begin to pull and bend the joint? A bad fitting shoe could be the cause but it usually isn?t the primary cause. Many people are genetically predisposed to hammertoe, and the condition begins to progress more quickly when they wear shoes that fit poorly, for example pointy toes, high heels, or shoes that are too short. Hammertoe may also be caused by damage to the joint as a result of trauma.
Symptoms
If you have any of these symptoms, do not assume it is due to hammer toe. Talk to your doctor about symptoms such as a toe that curls down, corns on the top of a toe, calluses on the sole of the foot or bottom of the toe, pain in the middle joint of a toe, discomfort on the top of a toe, difficulty finding any shoes that fit comfortably, cramping in a toe, and sometimes also the foot and leg, difficult or painful motion of a toe joint, pain in the ball of the foot or at the base of a toe.
Diagnosis
The exam may reveal a toe in which the near bone of the toe (proximal phalanx) is angled upward and the middle bone of the toe points in the opposite direction (plantar flexed). Toes may appear crooked or rotated. The involved joint may be painful when moved, or stiff. There may be areas of thickened skin (corns or calluses) on top of or between the toes, a callus may also be observed at the tip of the affected toe beneath the toenail. An attempt to passively correct the deformity will help elucidate the best treatment option as the examiner determines whether the toe is still flexible or not. It is advisable to assess palpable pulses, since their presence is associated with a good prognosis for healing after surgery. X-rays will demonstrate the contractures of the involved joints, as well as possible arthritic changes and bone enlargements (exostoses, spurs). X-rays of the involved foot are usually performed in a weight-bearing position.
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 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.
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 hammertoe 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.
