Understanding Accessory Navicular Syndrome: Causes, Symptoms, and Treatment
Feb 28, 2024Introduction:
Foot pain can disrupt daily life, and one condition that causes discomfort is Accessory Navicular Syndrome (ANS). While not as commonly known as other foot issues such as plantar fasciitis or bunions, ANS can significantly impact those affected.
What is Accessory Navicular Syndrome?
Accessory Navicular Syndrome, also known as Os Tibiale Externum or os navicularum, is a condition characterised by the presence of an additional piece of bone or cartilage adjacent to the navicular bone, located on the inner side of the foot, just above the arch. This additional piece, known as the accessory navicular, can vary in size and shape among individuals.
Causes:
The exact cause of Accessory Navicular Syndrome is not fully understood. However, it is believed to be a congenital anomaly, meaning individuals are born with it. The presence of the accessory navicular bone itself isn't problematic for everyone. It's when it becomes aggravated or inflamed that symptoms arise. Activities that involve repetitive stress or pressure on the foot, such as running or participating in sports that require frequent pivoting and jumping, can exacerbate the condition. Additionally, poorly fitting shoes or excessive pronation (rolling inwards) of the foot may contribute to its development.
Symptoms:
Symptoms of Accessory Navicular Syndrome can vary in severity and may include:
- Pain and tenderness along the inner side of the foot, particularly near the navicular bone.
- Swelling or redness in the affected area.
- Difficulty wearing shoes due to discomfort.
- Development of a visible bump or prominence on the inner aspect of the foot.
- Pain that worsens with physical activity or prolonged periods of standing.
Diagnosis:
Diagnosing Accessory Navicular Syndrome typically involves a thorough physical examination by one of our experienced podiatrist, including palpation of the affected area to assess tenderness and mobility. Imaging tests such as X-rays or MRI scans may also be needed to visualise the accessory navicular bone and evaluate any associated structural abnormalities.
Treatment:
The management of Accessory Navicular Syndrome aims to alleviate pain, reduce inflammation, and improve foot function. Treatment options may include:
- Rest and Activity Modification: Avoiding activities that exacerbate symptoms and incorporating rest periods can help alleviate pain and promote healing.
- Immobilisation: Wearing a brace or cast may be recommended to immobilise the foot and reduce stress on the affected area.
- Orthotic Devices: Custom orthotic inserts or arch supports can help provide stability and support to the foot, reducing strain on the accessory navicular bone.
- Exercise and Stretches: Specific exercises and stretches prescribed by our podiatrist can help strengthen the muscles surrounding the foot and improve flexibility, promoting proper alignment and reducing discomfort.
- Laser Therapy: Laser Therapy has shown to give anti inflammatory effects, which can help alleviate pain and also give analgesic effects.
- Medications: Nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen or naproxen may be recommended to alleviate pain and inflammation.
- Corticosteroid Injections: In cases of severe pain and inflammation, corticosteroid injections may be administered directly into the affected area to provide temporary relief.
- Surgery: If conservative treatments fail to provide relief, surgical intervention may be considered. Surgical options may involve removing the accessory navicular bone, realigning the foot's structure, or repairing damaged tissues.
Conclusion:
Accessory Navicular Syndrome can cause discomfort and affect one's ability to engage in daily activities comfortably. However, with proper diagnosis and appropriate management, individuals with ANS can experience significant improvement in symptoms and overall foot function.
