What Is Os Trigonum Syndrome?

Call our foot surgeons in Bozeman or Livingston, MT if you experience these symptoms

Os trigonum syndrome is an extra bone that develops behind the ankle bone. You may have an extra bone in one or both feet at birth. Many people don’t know they have os trigonum syndrome until symptoms are triggered by an injury. Symptoms may include:

  • Deep pain in the back of the ankle when pushing off of the big toe
  • Tenderness in the area when touched
  • Swelling in the back of the ankle

Os trigonum syndrome is often mistaken as an Achilles injury, ankle sprain or talus fracture. To diagnose os trigonum syndrome, you need to schedule an appointment at Bozeman Foot and Ankle Clinic to have a foot and ankle surgeon examine the area. Contact us today to schedule your appointment.

How to treat os trigonum syndrome

Treatment options include immobilization, anti-inflammatory drugs or injections to reduce inflammation. While most symptoms improve with nonsurgical treatment, your doctor may recommend surgery to remove the os trigonum.
