Overview An accessory navicular bone is a common finding on many foot x-rays. Most accessory naviculars are asymptomatic. However, in some patients the prominent bone on the inside of foot will create discomfort, which leads to difficulty with shoe fitting. Alternatively, the fibrous union between the navicular bone and the ?extra? accessory part may become irritated and cause discomfort. Diagnosis is completed through physical examination and plain x-rays of the foot. Treatment is usually non-operative, often including a change in shoe wear and activity modification. However, patients that have ongoing symptoms once non-surgical treatments are tried, often consider surgery to remove the prominent accessory navicular and, if necessary, reattach the posterior tibial tendon. Causes Most of the time, this condition is asymptomatic and people may live their whole lives unaware that they even have this extra bone. The main reason the accessory navicular bone becomes problematic is when pain occurs. There is no need for intervention if there is no pain. The accessory navicular bone is easily felt in the medial arch because it forms a bony prominence there. Pain may occur if the accessory bone is overly large causing this bump on the instep to rub against footwear. Symptoms Symptoms of this syndrome would include redness, swelling and tenderness over the navicular bone. The navicular bone is located on the inside of the foot approximately midway between the ankle bone and big toe joint. It will tend to be worse after activity and can be aggravated by those that wear very dressy shoes as opposed to casual shoes like sneakers. In other words, the flatter or less supportive the shoe, the greater the chance for pain. Diagnosis Your podiatrist will most likely diagnose accessory navicular syndrome by making a visual study of the area, checking whether the shape of your foot and your ability to move it indicate there?s an accessory navicular lurking around. He or she may push on the prominence on your foot to check to see if it hurts, and may ask you to walk around in order to ascertain how your gait is affected. In order to get a certain diagnosis, your podiatrist will need some way to see the inside of your foot, which will most likely involve getting X-rays, or possibly an MRI or some other scan of your foot?s interior. Non Surgical Treatment Non-surgical treatments are enough to cure the symptoms caused by the accessory navicular. The treatment options include Immobilization, a cast or a walking boot is usually used to immobilize the foot so that the inflammation and pain are alleviated quickly due to the rest that the foot gets. Apply ice bags or wrap the ice in a towel and apply it on the aching region to alleviate inflammation. Orthotic devices that can be fit into the shoes are prescribe to keep the symptoms from resurfacing. Exercises are helpful for strengthening the muscles, which would not only help alleviate inflammation but also keep the symptoms from appearing again. NSAIDs and steroids may be prescribed as per the need of the patient to ease the pain and inflammation. Surgical Treatment If non-surgical treatment fails to relieve the symptoms of accessory navicular syndrome, surgery may be appropriate. Surgery may involve removing the accessory bone, reshaping the area, and repairing the posterior tibial tendon to improve its function. This extra bone is not needed for normal foot function.

The accssory navicular bone presents as a sesamoid in the posterior tibial tendon, in articulation with the navicular or as an enlargment of the navicular. Navicular (boat shaped) is an intermediate tarsal bone on the medial side of the foot. It is located on the medial side of the foot, and articulates proximally with the talus. Distally it articulates with the three cuneiform bones. In some cases it articulates laterally with the cuboid. The tibialis posterior inserts to the os naviculare. The tibialis posterior muscle also contracts to produce inversion of the foot and assists in the plantar flexion of the foot at the ankle. Tibialis posterior also has a major role in supporting the medial arch of the foot. This supports is compromised by abnormal insertion of the tendon into the accessory navicular bone when present. This lead to loss of suspension of tibialis posterior tendon and may cause peroneal spastic pes planus or simple pes planus. But, yet a cause and effect relationship between the accessory navicular and pes planus is doubtful and is yet unproved clearly.<br><br><br><br>Causes<br>An injury to the fibrous tissue connecting the two bones can cause something similar to a fracture. The injury allows movement to occur between the navicular and the accessory bone and is thought to be the cause of pain. The fibrous tissue is prone to poor healing and may continue to cause pain. Because the posterior tibial tendon attaches to the accessory navicular, it constantly pulls on the bone, creating even more motion between the fragments with each step.<br><br>Symptoms<br>Not everyone who has an accessory navicular will develop these problems. 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. Pain may be worse towards the end of the day, and continue into the night. Among adults, symptomatic accessory navicular is more common in women than in men, with onset typical at 40 years of age or greater. Among symptomatic children, the mean age of onset for maels is 6 years, and for females, 4.5 years. In general, symptoms may occur between 2 and 9 years of age.<br><br>Diagnosis<br>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.

An orthotic may be recommended or the patient may undergo a brief period of casting to rest the foot. For chronic pain, however, the orthopedic surgeon removes the extra bone, a relatively simple surgery with a brief rehabilitation period and a very good success rate.<br><br><br><br>Surgical Treatment<br>If all nonsurgical measures fail and the fragment continues to be painful, surgery may be recommended. The most common procedure used to treat the symptomatic accessory navicular is the Kidner procedure. A small incision is made in the instep of the foot over the accessory navicular. The accessory navicular is then detached from the posterior tibial tendon and removed from the foot. The posterior tibial tendon is reattached to the remaining normal navicular. Following the procedure, the skin incision is closed with stitches, and a bulky bandage and splint are applied to the foot and ankle. You may need to use crutches for several days after surgery. Your stitches will be removed in 10 to 14 days (unless they are the absorbable type, which will not need to be taken out). You should be safe to be released to full activity in about six weeks.
