Overview<br>Accessary bone syndrome affects overpronators because of irritation in this area. Improper fitting shoes can also irritate the area. When pain becomes such that it changes running form or becomes intolerable, something needs to be done. Surgery alone without addressing causative factors is useless. Pain returns and new cartilage returns in the tendon, and the inflammation causes pain.<br><br><br><br>Causes<br>This painful foot condition is caused by an extra bone in the foot called the accessory navicular. Only about 10% of people have this bone (4 to 21%), and not all of them will develop any symptoms. The navicular bone is one of the normal tarsal bones of the foot.

When problems do occur, they may begin in early adolescence. The obvious indication is a painful bump on the inside of the foot, which hurts to touch, and causes problems that gradually become worse, and which are aggravated by activity, walking, etc., leading to all the problems discussed here.

Therefore, it is recommended that either shoes with plenty of padding and space in the ankle area are purchased, or pre-owned shoes can be modified by a shoemaker to create extra space in this area. For example, many patients will get their ski boots expanded in the area around the prominence, minimizing irritation. In addition, a shoe with a stiff sole will help disperse force away from the arch of the foot during walking, thereby minimizing the force on the posterior tibial tendon. An off-the-shelf arch support may help decrease the stress applied by the posterior tibial tendon. If necessary, an ankle brace applied to provide more substantial support to the arch may be successful where a simple arch support fails.<br><br><br><br>Surgical Treatment<br>Once the navicular inflammation has lessened it is not necessary to perform surgery unless the foot becomes progressively flatter or continues to be painful. For these children, surgery can completely correct the problem by removing the accessory navicular bone and tightening up the posterior tibial tendon that attaches to the navicular bone. The strength of this tendon is integral to the success of this surgery as well as the arch of the foot. Following surgery the child is able to begin walking on the foot (in a cast) at approximately two weeks. The cast is worn for an additional four weeks. A small soft ankle support brace is then put into the shoe and worn with activities and exercise for a further two months.

Overview
Some people, possibly beginning in early adolescents, but perhaps later, can develop a painful bump on the side of their foot. The pain may be worse after athletic activity or just normal walking, and walking itself may become painful. This pain may become constant, but it will tend to improve with continued rest. Depending on the size of the bump, it may rub against shoes, or cause pain if the bump is hit by something. Over time, the arch of the foot may be lost and a flat food will develop.



Causes
People who have an accessory navicular often are unaware of the condition if it causes no problems. However, some people with this extra bone develop a painful condition known as accessory navicular syndrome when the bone and/or posterior tibial tendon are aggravated. This can result from any of the following. Trauma, as in a foot or ankle sprain. Chronic irritation from shoes or other footwear rubbing against the extra bone. Excessive activity or overuse.

Symptoms
Most people with an accessory navicular do not have symptoms because the bone is so small that it causes no harm, or only develop symptoms after a trauma such as a break or sprain. When symptoms are present they could be a visible bony prominence, pain and throbbing, inflammation and redness, and flat feet.

Diagnosis
To diagnose accessory navicular syndrome, medical staff ask about the patient?s activities and symptoms. They will examine the foot for irritation or swelling. Medical staff evaluate the bone structure, muscle, joint motion, and the patient?s gait. X-rays can usually confirm the diagnosis. MRI or other imaging tests may be used to determine any irritation or damage to soft-tissue structures such as tendons or ligaments. Because navicular accessory bone irritation can lead to bunions, heel spurs and plantar fasciitis, it?s important to seek treatment.

Non Surgical Treatment
Treating accessory navicular syndrome is focused on relieving symptoms. Some treatment methods are Icing to reduce swelling. Immobilization with a cast or walking boot to reduce inflammation and promote healing. Medications to reduce pain and inflammation. Physical therapy to strengthen muscles. Orthotics to support the arch. Surgery may be needed to remove the accessory bone and reshape the area if other methods are not successful.



Surgical Treatment
If your pain and discomfort don’t go away with treatments like these, then it may be time to consider surgery. If you decide to go through with it, your surgeon will probably remove the accessory navicular once and for all, and will tighten up the posterior tibial tendon in order to make it better able to support your arch. You’ll probably have to wear a cast for a several weeks, and a brace for some months after that, but with patience, you may be able to say goodbye to your symptoms.
