Overview<br>The navicular bone is located on the top of the foot near the arch. People who have this extra bone can feel a bump or bony protuberance on the top of the foot above the arch. While the bone itself does not cause pain, accessory navicular syndrome can develop when the bone and/or nearby tendon is irritated. The navicular bone is attached to muscles, ligaments and the posterior tibial tendon. Since ligaments and tendons have poor blood supply and don?t heal easily, any irritation to the surrounding structures can develop into a painful condition.<br><br><br><br>Causes<br>The syndrome may result from any of the following, previous trauma such as a foot or ankle sprain. Chronic irritation from shoes or other footwear causing friction against the bone. Strain from overuse or excessive activity.<br><br>Symptoms<br>Symptoms of accessory navicular syndrome often appear in adolescence, when bones are maturing. Symptoms include A visible bony prominence on the midfoot, Redness and swelling, Vague pain or throbbing in the arch, especially after physical activity.<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. Because navicular accessory bone irritation can lead to bunions, [http://ailenebrim.blogas.lt/ heel spurs] and plantar fasciitis, it?s important to seek treatment.<br><br>Non Surgical Treatment<br>Excess weight will increase the force on the posterior tibial tendon as it inserts into the accessory navicular and will tend to precipitate or aggravate symptoms. If a patient with a symptomatic accessory navicular is overweight, then losing weight can be very helpful. Even losing 5-10lbs will decrease the amount of force going through the foot with each step by as much as 15-30lbs. This is because the foot acts like a lever serving to magnify the force absorbed by the foot with each step.<br><br><br><br>Surgical Treatment<br>If conservative measures do not seem to help, however, you may need to have surgery to make adjustments to the bump. This could include reshaping the little bone, repairing damage to the posterior tibial tendon, or even removing the accessory navicular altogether.
