How do you get achilles tendonitis?

Large Accessory Navicular Bone


Overview
Everyone has one navicular bone: one of the small bones of the foot. A small number of people have a second small navicular bone or piece of cartilage located on the inside of the foot just above the arch: both are simply called an "accessary navicular bone." It is located within the posterior tibial tendon which attaches in this area. It is easy to see as a "bump." Most that have it never have pain. If they get pain, we call it: "Accessary navicular bone syndrome."

Accessory Navicular Syndrome

What causes pain in the back of the heel?
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.

Symptoms
If you develop accessory navicular syndrome, you may experience a throbbing sensation or other types of pain in your midfoot or arch (especially while or right after you use the foot heavily, such as during exercise), and you may notice a bony prominence on the interior of your foot above the arch. This prominence may become inflamed, which means it will likely feel warm to the touch, look red and swollen, and will probably hurt.

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.

Accessory Navicular

Surgical Treatment
Surgery may be an option if non-surgical treatment does not decrease the symptoms of accessory navicular syndrome. Since this bone is not needed for the foot to function normally, Your surgeon may remove the accessory navicular, reshape the area, and repair the posterior tibial tendon for improved function.

Does Accessory Navicular Syndrome Always Warrant Surgery


Overview
When there is injury to the muscle, fibrous tissue, or soft tissue of the navicular and the accessory navicular bones, symptoms will arise. This injury allows excessive movement between the bones. Fibrous tissue, ligaments and tendons have poor blood supply and are prone to poor healing. Often, this extra navicular bone lies near or attaches to the posterior tibial tendon. (See figure.) When the posterior tibial muscle contracts with movements such as foot inversion or plantar flexion, the posterior tendon moves and the accessory navicular bone moves. This can cause severe pain in those with Accessory Navicular Syndrome. It can become disabling to patients because the posterior tibial tendon attached to the navicular bone is responsible for supporting the medial arch during standing, walking and running. Activities which most of us do daily!

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.

This prominence may become inflamed, which means it will likely feel warm to the touch, look red and swollen, and will probably hurt.

Diagnosis
A foot and ankle surgeon can diagnose accessory navicular syndrome by conducting a physical exam. X-rays and MRIs may be taken to access the condition and confirm the diagnosis of accessory navicular.

Non Surgical Treatment
For less severe symptoms, decreasing or modifying activity, such as avoiding aggravating activities, may suffice. Ice and NSAIDS How can you heal an Achilles tendonitis fast? be used to help control pain. An arch support or an orthotics may help to stabilize the arch during this time. When rubbing on the bump causes pain, a doughnut pad can be worn. Exercises to increase range of motion and improve movement should still be used.

Accessory Navicular Syndrome

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.
