Accessory Navicular

The accessory navicular is an extra bone or bony prominence located near the navicular bone, which is part of the foot. While some people may have this extra bone without any issues, for others, it can cause pain and discomfort, especially during activities that put stress on the foot. In this article, we’ll explore what the accessory navicular is, its causes, symptoms, and treatment options.

What is an Accessory Navicular (Accessory Navicular Bone)?

An accessory navicular, also known as an accessory navicular bone or os naviculare, is an extra bone that develops near the navicular bone in the foot. This additional bone is formed during the fetal development stage.

Causes of Accessory Navicular (Accessory Navicular Syndrome)

The exact cause of an accessory navicular is not fully understood, but it is believed to be congenital, meaning it is present at birth. It is thought to be an inherited trait, with some individuals being more predisposed to developing this condition.

Symptoms of Accessory Navicular (Accessory Navicular Pain)

While some people with an accessory navicular may not experience any symptoms, others may experience the following:

• Pain and tenderness in the midfoot area, particularly on the inner side of the foot
• Swelling and redness around the accessory navicular bone
• Difficulty wearing certain types of shoes due to pressure on the affected area
• Pain that worsens with physical activity or prolonged standing

Diagnosis of Accessory Navicular (Accessory Navicular X-Ray)

If you are experiencing foot pain or discomfort, your healthcare provider may recommend the following diagnostic tests to determine if you have an accessory navicular:

• Physical examination: Your healthcare provider will examine your foot and assess the area of pain or tenderness.
• X-ray: An X-ray is the most common diagnostic tool used to detect the presence of an accessory navicular bone.
• Other imaging tests: In some cases, your healthcare provider may recommend additional imaging tests, such as a CT scan or MRI, to better visualize the accessory navicular and surrounding structures.

Treatment Options for Accessory Navicular (Accessory Navicular Surgery)

The treatment for an accessory navicular depends on the severity of the symptoms and the individual’s overall health and activity level. Here are some common treatment options:

1. Conservative treatment:

• Rest and ice application to reduce inflammation and pain
• Over-the-counter or prescription anti-inflammatory medications
• Orthotics or arch supports to help redistribute pressure and support the foot
• Physical therapy exercises to strengthen the foot and ankle muscles

2. Surgical treatment: If conservative treatments fail to provide relief, surgery may be recommended. The most common surgical procedure for an accessory navicular is the removal of the extra bone (accessory navicular excision).

Conclusion

The accessory navicular is an extra bone near the navicular bone. While some individuals may not experience any symptoms, others may experience pain, swelling, and discomfort, especially during physical activity. If you suspect you have an accessory navicular, it is important to seek medical attention for proper diagnosis and treatment. With the right approach, whether conservative or surgical, most individuals can find relief from the discomfort caused by this condition and continue to lead an active lifestyle.
