An accessory navicular bone is an accessory bone of the foot that occasionally develops abnormally in front of the ankle towards the inside of the foot. This bone may be present in approximately 2-14% of the general population and is usually asymptomatic. When it is symptomatic, surgery may be necessary. Surgery can be performed at any age because it How much does it غير مجاز مي باشدt for leg lengthening? not alter any other bones.
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.
Many people with an accessory navicular do not experience symptoms, however some may notice a bump and/or swelling on the inside of the foot just above the arch. They may also experience pain in the middle of the foot, particularly with physical activity.
An initial assessment is an orthopaedic office begins with a thorough history and complete physical exam, including an assessment of the posterior tibial tendon and areas of tenderness. Associated misalignments of the ankle and foot should be noted. Finally, weight-bearing x-rays of the foot will help in making the diagnosis. Sometimes, an MRI may be needed to see if the posterior tibial tendon is involved with the symptoms or getting more clarity on the anatomy of the accessory navicular.
Non Surgical Treatment
If the foot becomes painful following a twisting type of injury and an X-ray reveals the presence of an accessory navicular bone, your doctor may recommend a period of immobilization in a cast or splint. This will rest the foot and perhaps allow the disruption between the navicular and accessory navicular to heal. Your doctor may prescribe anti-inflammatory medication. Sometimes an arch support can relieve the stress on the fragment and decrease the symptoms. If the pain subsides and the fragment becomes asymptomatic, further treatment may not be necessary.
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.
