27 Aug 2018 Accessory Navicular Syndrome
The accessory navicular is an extra bone or piece of cartilage located on the inside of the foot just above the arch. It is located within the posterial tibial tendon that attaches to this navicular bone.
An accessory navicular bone is present at birth. It is not incorporated in the normal bone structure and is not present in most people.
Generally, people who have an extra navicular are often unaware that they have this deformity if it does not cause any pain or other problems. However, some people with this accessory bone develop accessory navicular syndrome due to the pain that it causes them. This occurs when the bone or the tendon is aggravated, resulting in trauma, irritation from shoes rubbing against the accessory bone or from excessive physical activity.
Adolescence is a common time for the symptoms to first appear. This is because the bones are maturing and developing. Symptoms of the condition are as follows:
- visible bony prominence on the midfoot
- redness and swelling of the bony prominence
- pain in the arch or midfoot
To diagnose this foot condition, the podiatrist will enquire about symptoms and examine the foot. Joint motion, muscle strength and gait assessments will also be evaluated.
X rays are commonly ordered to confirm the diagnosis.
The main goal is to relieve symptoms. This can be done through:
- Anti-inflammatory medications
- Icing the affected area
- Strengthening exercises
