Os Trigonum Syndrome

What is Os Trigonum Syndrome?

Os Trigonum Syndrome is a common source of pain at the back of the ankle, particularly for those involved in activities that involve repetitive downward pointing of the toes. This condition arises from the presence of an extra bone, known as the os trigonum, located just behind the ankle joint. While some individuals are born with this accessory bone, it often goes unnoticed until pain and discomfort begin to develop in the heel area.

Why Does the Pain at the Back of the Heel Start?

The accessory bone itself doesn’t typically cause pain, but when the ankle is repeatedly bent downward, reducing the space at the back of the joint, it can compress the os trigonum. This compression can damage the surrounding soft tissues, leading to pain, swelling, and tenderness in the heel, which worsens with movements like walking or pointing the toes downward.

How is Os Trigonum Syndrome Treated?

1. Confirm the Diagnosis:
   The first step is to confirm the presence of the os trigonum with an X-ray. Since other conditions like retrocalcaneal bursitis or Achilles tendonitis can cause similar symptoms, confirming the diagnosis is essential.

2. Rest and Reduce Swelling:
   Resting the foot and avoiding movements that irritate the accessory bone are crucial. Ice, elevation, and non-steroidal anti-inflammatory drugs (NSAIDs) can help reduce swelling and pain.

3. Supportive Treatments:
   To aid healing and prevent future irritation, your podiatrist may recommend custom foot orthotics, suitable footwear (avoiding heels), physical therapy to strengthen the surrounding muscles, or even a brace or boot to reduce movement and further irritation.

4. Surgical Treatment:
   If non-surgical treatments do not provide relief and symptoms persist, surgery to remove the accessory bone may be considered. However, conservative treatments are effective in most cases and are typically recommended first.
