Accessory Trigonum Resection

Expert orthopedic surgeons at Pathway remove painful extra bone (accessory or os trigonum) growth behind your ankle through precise surgical techniques.

What Is the Accessory Trigonum?

The accessory trigonum is an extra bone (called an accessory ossicle) located behind the ankle, near the talus bone. Not everyone has this bone, but in some people — especially athletes and ballet dancers — it can become painful due to repetitive downward ankle motion (plantarflexion).

Why Is It Important?

This area involves key ligaments and tendons that help control ankle motion.
When the accessory trigonum gets pinched or irritated, it can lead to:

  • Posterior ankle pain (especially when pointing toes)

  • Swelling and stiffness

  • Limited ankle range of motion
    This condition is often called Posterior Ankle Impingement Syndrome.

How Is the Procedure Done?

Accessory Trigonum Resection is a minimally invasive surgery used to remove the small bone fragment and relieve pressure in the back of the ankle.

✅ Step-by-step Overview:

  1. Small incisions are made around the ankle.

  2. tiny camera (arthroscope) and instruments are inserted to visualize the area.

  3. The accessory bone is gently removed.

  4. Inflamed tissue may also be cleaned out.

The incisions are closed with minimal scarring.
