Overview<br>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 [http://pearlegrunder.jimdo.com/2015/06/27/hammertoe-repair-without-surgery 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.<br><br><br><br>Causes<br>An accessory navicular develops as a result of a congenital anomaly and is found more often in women. If the bone is large, it may rub against a shoe, causing pain. Because of its location, the posterior tibial tendon may pull on the bone during walking or running, causing the fibrous tissue that connects the accessory navicular to the navicular to tear and become inflamed.<br><br>Symptoms<br>Symptoms of accessory navicular syndrome often appear in adolescence, when bones are maturing.

There are three main types of accessory navicular bones:  a small bone embedded within the nearby posterior tibial tendon; a triangular shaped bone connected to the navicular by thick cartilage; and a large prominent navicular tuberosity thought to represent an accessory navicular that has fused to the navicular. If the status of the posterior tibial tendon needs to be assessed or if other problems are suspected, (ex. Navicular stress fracture) it may be necessary to perform an MRI. Although this is not considered routine, an MRI may be helpful in identifying the degree of irritation.

Standard non-surgical treatment includes shoes that are soft around the inside of the ankle can allow for any excess prominence of bone. 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>Surgical treatment of the accessory navicular syndrome with simple excision has the advantages of less invasive to the posterior tibial tenden and the medial longitudinal arch of the foot, shorter time of immobilization of the foot and stay in hospital, small incision and good clinical results.

Overview
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 What is a heel lift? useless. Pain returns and new cartilage returns in the tendon, and the inflammation causes pain.



Causes
Let us see the reasons why the tendon or the bone would get aggravated. Ankle or foot sprain, irritation of the bone caused by footwear, overusing the foot, quite common in athletes and dancers. People born with this extra bone are also known develop flat feet which also adds to the strain on the posterior tibial tendon and lead to the syndrome.

Symptoms
Symptoms of accessory navicular include. Bone lump on the inside of the foot. Redness and swelling. Pain.

Diagnosis
The foot and ankle are prone to bony ?accessories? which usually have no accompanying symptoms. Accessory navicular syndrome is often diagnosed when an adolescent complains of pain in the foot. Girls are more susceptible than boys, and the condition is usually bilateral, occurring in both feet. Navicular accessory syndrome may be diagnosed when a trauma (foot or ankle sprain) aggravates the bone or tibial tendon, or when there is chronic irritation from footwear or overuse.

Non Surgical Treatment
Most children?s symptoms are improved or resolved by taking a break from activities that irritate their feet. Shoe inserts that pad the accessory navicular area are also helpful. If your child?s symptoms do not improve, your physician may recommend a below-the-knee cast or walking boot. Surgery is rarely needed.



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.
