What is Crossover Toe?
Crossover toe is a condition in which the second toe drifts toward the big toe and eventually crosses over and lies on top of the big toe. Crossover toe is a common condition that can occur at any age, although it is most often seen in adults.
Some people confuse crossover toe with a hammertoe, probably because both conditions involve a toe that does not lie in the normal position. However, crossover toe is entirely different from a hammertoe—and much more complex.
Symptoms of Crossover Toe
Although the crossing over of the toe usually occurs over a period of time, it can appear more quickly if caused by injury or overuse. Symptoms may include:
- Pain, particularly on the ball of the foot. It can feel like there’s a marble in the shoe or a sock is bunched up.
- Swelling in the area of pain, including the base of the toe.
- Difficulty wearing shoes.
Crossover toe is a progressive disorder. In the very early stages—the best time to treat crossover toe—a patient may have pain but no crossover of the toe. Without treatment, the condition usually worsens to dislocation of the joint, so it is very beneficial to have a podiatrist evaluate the foot soon after pain first occurs.
What Causes Crossover Toe?
It is generally believed that crossover toe is a result of abnormal foot mechanics, where the ball of the foot beneath the second toe joint takes an excessive amount of weight- bearing pressure. This pressure eventually leads to weakening of the supportive ligaments and a failure of the joint to stabilize the toe, resulting in the toe crossing over. Another common cause is injury.
Certain conditions or characteristics can make a person prone to experiencing excessive pressure on the ball of the foot. These most commonly include a severe bunion deformity, a second toe longer than the big toe, an arch that is structurally unstable and a tight calf muscle.
Crossover toe is sometimes misdiagnosed, especially in the early stages when there is pain but the toe has not yet crossed over. The pain experienced in crossover toe mimics a condition called Morton’s Neuroma. The two disorders, however, are treated very differently—making it crucial to obtain an accurate diagnosis. In arriving at a diagnosis, the podiatrist will examine the foot, press on it and maneuver it to reproduce the symptoms. The surgeon will also look for potential causes and test the stability of the joint. X-rays are usually ordered, and other imaging studies are sometimes needed. One of the newest imaging choice is the diagnostic ultrasound which is similar to an MRI as it visualizes many changes in the soft tissue.
Treatment: Non-surgical Approaches
The best time to treat crossover toe is in the early stages, before the toe starts to drift toward the big toe. At that time, non-surgical approaches can be used to stabilize the joint, reduce the symptoms and address the underlying cause of the condition.
The podiatrist may select one or more of the following options for early treatment of crossover toe:
- Rest and ice. Staying off the foot and applying ice packs help reduce the swelling and pain.
- Oral medications. Non-steroidal anti-inflammatory drugs, such as ibuprofen, may help relieve the pain and inflammation.
- Immobilization. Sometimes the foot is immobilized for a while so that the injured tissue can heal.
- Taping/splinting. It may be necessary to tape the toe so that it will stay in the correct position. This helps relieve the pain and prevent further drifting of the toe.
- Stretching. Keeping the calf muscles stretched is important in patients who have tight calf muscles.
- Shoe modifications. Supportive shoes with stiff soles are recommended because they control the motion and lessen the amount of pressure on the ball of the foot.
- Orthotic devices. Custom shoe inserts are often very beneficial. These include arch supports or a metatarsal pad that distributes the weight away from the joint.
When is Surgery Needed?
Once the second toe starts moving toward the big toe, it will never go back to its normal position unless surgery is performed. The podiatrist will select the procedure or combination of procedures best suited to the individual patient
