Accessory Tarsal Navicular Pain


Overview
The accessory navicular is an ossicle, or extra bone located medially to the navicular. Depending on the type, or stage, it may be connected to the navicular by a fibrous union, via a type of joint called a synchrondrosis. In those who have this extra bone, it is present at birth, but it starts as soft cartilage and then begins to ossify (turn into bone) at around age nine. Some sources believe that, in about half of those who have it, the bone will fuse to the navicular in late adolescence, but it is not clear that this actually happens.

Accessory Navicular

Causes
This painful foot condition is caused by an extra bone in the foot called the accessory navicular. Only about 10% of people have this bone (4 to 21%), and not all of them will develop any symptoms. The navicular bone is one of the normal tarsal bones of the foot. It is located on the inside of the foot, at the arch.

Symptoms
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.

Diagnosis
To diagnose accessory navicular syndrome, the foot and ankle surgeon will ask about symptoms and examine the foot, looking for skin irritation or swelling. The doctor may press on the bony prominence to assess the area for discomfort. Foot structure, muscle strength, joint motion, and the way the patient What makes you grow taller during puberty? walks may also be evaluated. X-rays are usually ordered to confirm the diagnosis. If there is ongoing pain or inflammation, an MRI or other advanced imaging tests may be used to further evaluate the condition.

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.

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.

Extra Bone In Foot Accessory Navicular


Overview
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 does not alter any other bones.

Accessory Navicular

Causes
This can result from any of the following. Trauma, as in a foot or ankle sprain. Chronic irritation from shoes or other footwear rubbing against the extra bone. Excessive activity or overuse. Many people with accessory navicular syndrome also have flat feet (fallen arches). Having a flat foot puts more strain on the posterior tibial tendon, which can produce inflammation or irritation of the accessory navicular.

Symptoms
Possible symptoms of accessory navicular syndrome include redness or swelling in the area of the accessory navicular, and pain that is present around the middle of the foot around the arch. Discomfort is most often present following periods of exercise or prolonged walking or standing. The bone may be somewhat visible on the inside of the foot above the arch. Most symptoms of accessory navicular syndrome first appear in childhood around the time of adolescence as the bones are still growing and developing. For some with an accessory navicular, though, symptoms may not appear until entering adulthood.

Diagnosis
Diagnosis starts by speaking with the patient about symptoms. The physician will look at the foot and examine it for signs of an accessory navicular. By putting pressure on the area, the doctor may determine its presence simply by the presence of pain. The muscle, joint, and the overall structure of the foot may be considered, as well as the way in which the patient walks. If a diagnosis of accessory navicular syndrome is made, an X-ray or MRI may be ordered to confirm diagnosis.

Non Surgical Treatment
Traditional medicine often falls short when it comes to treatment for this painful condition. As similar to other chronic pain conditions, the following regimen What is the Ilizarov method? usually recommended: RICE, immobilization, anti-inflammatory medications, cortisone injections, and/or innovative surgical options. Clients familiar with Prolotherapy often say? no thanks? to those choices, as they know these treatments will only continue to weaken the area in the foot. Instead, they choose Prolotherapy to strengthen the structures in the medial foot.

Accessory Navicular

Surgical Treatment
Depending upon the severity the non operative or conservative treatment should be maintained for at least 4- 6 months before any surgical intervention. There are 2 surgeries that can be performed depending upon the condition and symptoms. First is simple surgical excision. In this generally the accessory navicular along with its prominence is removed. In this procedure, skin incision is made dorsally to the prominence of accessory navicular. Bone is removed to the point where the medial foot has no bony prominence over the navicular, between the head of the talus and first cuneiform. Symptoms are relieved in 90% of cases. Second is Kindler procedure. In this the ossicle and navicular prominence is excised as in simple excision but along with the posterior tibial tendon advancement. Posterior tibial tendon is split and advanced along the medial side of foot to provide support to longitudinal arch. After surgery 4 week short leg cast, well moulded into the arch with the foot plantigrade is applied. Partial weight bearing till the 8th week and later full weight bearing is allowed. When the cast is being removed can start building up the ROM to counter atrophy and other physical therapy treatment which include stretching and strengthening exercises.
