A cavus or high-arched foot may have many foot shapes. This may range from an arch that is slightly high to a severe deformity that causes a patient to walk on the outside of the foot. Surgery is occasionally required to realign the foot. There are different causes of a high-arched foot. In many cases, the cause is unknown. In other cases, the cause is a nerve disease, clubfoot or injury. Treatment ranges from changes in shoewear to surgeries, depending on the amount of deformity and related problems.
There are many different causes of flat feet, which can be separated into two main categories. The first category, congenital flat foot, is a condition that one is born with or is predisposed to at birth. This type includes the completely asymptomatic, pediatric flexible flat foot-by far the most common form of congenital flat foot. Flexible means that an arch is present until weight is put on the foot, at which time the arch disappears. This foot type is a result of the fact that all people are born with different physical features. Some people have bigger noses than others, just as some people have flatter feet (of course, there is no known correlation between the two). Any alteration in the many building blocks of the foot can influence its shape.
Arch pain may have a variety of different causes. Proper evaluation and diagnosis of arch pain is essential in planning treatment. A good general guideline is to compare the injured side to the uninjured side. Injury may present itself as a distinguishable lump, a gap felt at that location, or a "crunchy" feeling on that spot caused by inflammation. The type, causes, and severity of pain are also good indicators of the severity of the injury.
The adult acquired flatfoot, secondary to posterior tibial tendon dysfunction, is diagnosed in a number of ways with no single test proven to be totally reliable. The most accurate diagnosis is made by a skilled clinician utilizing observation and hands on evaluation of the foot and ankle. Observation of the foot in a walking examination is most reliable. The affected foot appears more pronated and deformed compared to the unaffected foot. Muscle testing will show a strength deficit. An easy test to perform in the office is the single foot raise.
Non Surgical Treatment
The treatment of a rigid flatfoot depends on its cause. Congenital vertical talus. Your doctor may suggest a trial of serial casting. The foot is placed in a cast and the cast is changed frequently to reposition the foot gradually. However, this generally has a low success rate. Most people ultimately need surgery to correct the problem. Tarsal coalition. Treatment depends on your age, extent of bone fusion and severity of symptoms. For milder cases, your doctor may recommend nonsurgical treatment with shoe inserts, wrapping of the foot with supportive straps or temporarily immobilizing the foot in a cast. For more severe cases, surgery is necessary to relieve pain and improve the flexibility of the foot. Lateral subtalar dislocation. The goal is to move the dislocated bone back into place as soon as possible. If there is no open wound, the doctor may push the bone back into proper alignment without making an incision. Anesthesia is usually given before this treatment. Once this is accomplished, a short leg cast must be worn for about four weeks to help stabilize the joint permanently. About 15% to 20% of people with lateral subtalar dislocation must be treated with surgery to reposition the dislocated bone.
In adults, the most common cause of collapse is due to the posterior tibial tendon tear. In such cases, the tendon must be repaired and a second tendon may be added to the posterior tibial tendon for strength and added support. If the foot is found to be very flat, bone realignment procedures or possible bone fusion procedures may be used to realign the foot. If the calf or Achilles tendon are found to be tight, they may be lengthened to allow better motion at the ankle and less arch strain. The forefoot may also be in a poor position and stabilization of the arch may be necessary to increase forefoot contact to the ground.
Maintain a healthy weight, Use insoles to support your arches, Limit how often you wear high heels, Use proper shoes, especially when exercising to evenly distribute weight through your foot.
Start in an L-Sit position. (If you?re hips and hamstrings are tight sit up on a box or phone book to be able to achieve a tall back position. You can even sit on a box with your back supported against a wall!) Keeping the legs straight, but not locked, reach both heels out away from your body to ?Flex? the ankles. Try to avoid pulling back with the toes to flex. Keep the toes relaxed and lead from the heel to hinge the foot into the flexed position. Hold the flexed foot and breathe. Take 3-5 breaths and see if you can reach farther through the heel to deepen the flex on each exhale. To transition to the pointed position, begin by pointing the foot to move the ankles as far as possible in the other direction. Once the ankles have reached their endpoint, use the muscles along the sole of the foot to point the toes. Inhale to continue lengthening out through the top of the foot, exhale to deepen the contraction under the sole of the foot to point the toes. Take 3-5 breaths. Then release the toes, and begin reaching out through the heel to hinge the ankle into the flexed position to repeat the exercise. Continue to flex and the point for 5-10 repetitions.
