Understanding Accessory Navicular Syndrome: Extra Bones In The Ankle

What is Accessory Navicular Syndrome?

Accessory Navicular Syndrome, also known as os tibiale externum or os naviculare accessorium, is a condition characterized by the presence of an extra bone in the foot, specifically in the ankle area. This additional bone, known as the accessory navicular, can cause pain and discomfort, particularly during physical activity or prolonged standing.

The prevalence of accessory navicular syndrome is estimated to be around 4-14% in the general population, with a higher incidence in females compared to males. It is often present from birth but may become symptomatic during adolescence or early adulthood. The exact cause of the condition is not fully understood, but it is believed to be related to abnormal development of the navicular bone during childhood.

Common symptoms of accessory navicular syndrome include localized pain, swelling, and redness in the midfoot area, particularly along the inner side of the foot. The pain may worsen during physical activity and may be accompanied by a visible bony prominence. In some cases, the condition may also lead to flat feet or fallen arches, contributing to further discomfort and difficulty with walking or standing for extended periods.

Diagnosis of accessory navicular syndrome typically involves a physical examination by a healthcare professional, as well as imaging studies such as X-rays or MRI scans to visualize the extra bone and assess any associated soft tissue damage. Treatment options for the condition may vary depending on the severity of symptoms and the individual's overall health. Conservative measures such as rest, ice, compression, and elevation (RICE), as well as the use of supportive footwear or orthotic inserts, may be recommended to alleviate pain and reduce stress on the affected area.

In cases where conservative measures are ineffective, or if the symptoms are severe and significantly impact the individual's quality of life, surgical intervention may be considered. Surgical procedures for accessory navicular syndrome may involve removal of the extra bone, as well as repair of any damaged ligaments or tendons. Recovery from surgery typically involves a period of immobilization and physical therapy to restore strength and function to the affected foot.

It is important for individuals with accessory navicular syndrome to seek appropriate medical care and follow the guidance of healthcare professionals to manage their condition effectively. Additionally, maintaining a healthy weight, engaging in regular physical activity, and wearing supportive footwear can help reduce the risk of complications and improve overall foot health.

Causes of Accessory Navicular Syndrome

Accessory navicular syndrome is a condition that affects the foot and ankle, causing pain and discomfort. The primary cause of this syndrome is the presence of an extra bone, known as the accessory navicular bone, in the inner side of the foot, near the arch. This condition is also known as os tibiale externum or os naviculare accessorium.

The exact cause of the development of an accessory navicular bone is not entirely understood, but it is believed to be a congenital anomaly, meaning that the extra bone is present at birth. Studies have shown that this condition is more common in females than in males, with a prevalence of about 2-21% in the general population.

Although the presence of the accessory navicular bone is congenital, symptoms of accessory navicular syndrome often do not appear until adolescence or early adulthood. The reason for this delayed onset of symptoms is thought to be related to the gradual ossification and maturation of the accessory navicular bone, which can lead to inflammation and pain in the affected area.

In some cases, the development of accessory navicular syndrome may be associated with trauma or overuse of the foot and ankle. Athletes who engage in activities that involve repetitive stress on the feet, such as running, jumping, or dancing, are at a higher risk of developing this condition. Additionally, individuals with flat feet or fallen arches may also be more susceptible to developing accessory navicular syndrome due to the altered biomechanics of the foot.

It is important to note that while the presence of an accessory navicular bone is a common anatomical variation, not all individuals with this extra bone will experience symptoms or require treatment. However, for those who do experience pain and discomfort, seeking medical attention and proper diagnosis is crucial in order to determine the most appropriate treatment options.

Symptoms to Look Out For

Accessory navicular syndrome, also known as extra bones in the ankle, can cause a variety of symptoms that can range from mild discomfort to severe pain. It is important to be aware of these symptoms in order to seek proper treatment and prevent further complications.

One of the most common symptoms of accessory navicular syndrome is pain and tenderness in the midfoot area, particularly on the inside of the foot. This pain can be aggravated by physical activity or prolonged standing, and may be accompanied by swelling and redness in the affected area.

Another symptom to look out for is the development of a visible bony prominence on the inside of the foot, just above the arch. This extra bone, known as the accessory navicular, can be felt as a hard lump under the skin and may cause discomfort when wearing certain types of shoes.

In some cases, individuals with accessory navicular syndrome may experience difficulty walking or running due to the pain and stiffness in the affected foot. This can significantly impact daily activities and overall quality of life.

It is also important to be aware of any changes in the structure or alignment of the foot, as accessory navicular syndrome can lead to flat feet or other foot deformities if left untreated.
