Os Trigonum Syndrome and How It Affects the Ankle

Os trigonum syndrome is a painful condition that occurs when an extra bone at the back of the ankle, called the os trigonum, becomes irritated. This small piece of bone is present in some people and usually does not cause problems. However, repetitive ankle movement, such as pointing the toes during ballet, soccer, or running, can trap this bone between the heel and ankle, leading to pain and swelling. Symptoms often include deep aching at the back of the ankle, tenderness when pressing on the area, and discomfort that worsens with activity. It may be mistaken for other ankle injuries, which is why an accurate diagnosis from a podiatrist is important. Treatment includes rest, anti-inflammatory medication, targeted exercise, or supportive footwear. In more severe cases, surgery to remove the os trigonum can relieve pain and restore ankle function. If you have pain or swelling at the back of your ankle, it is suggested that you schedule an appointment with a podiatrist for a diagnosis and proper treatment.

Ankle pain can be caused by a number of problems and may be potentially serious. If you have ankle pain, consult with Dr. Howard Horowitz from Bowie Foot & Ankle . Our doctor will assess your condition and provide you with quality foot and ankle treatment.

Ankle pain is any condition that causes pain in the ankle. Due to the fact that the ankle consists of tendons, muscles, bones, and ligaments, ankle pain can come from a number of different conditions.

Causes

The most common causes of ankle pain include:

  • Types of arthritis (rheumatoid, osteoarthritis, and gout)
  • Ankle sprains
  • Broken ankles
  • Achilles tendonitis
  • Achilles tendon rupture
  • Stress fractures
  • Bursitis
  • Tarsal tunnel syndrome
  • Plantar fasciitis

Symptoms

Symptoms of ankle injury vary based upon the condition. Pain may include general pain and discomfort, swelling, aching, redness, bruising, burning or stabbing sensations, and/or loss of sensation.

Diagnosis

Due to the wide variety of potential causes of ankle pain, podiatrists will utilize a number of different methods to properly diagnose ankle pain. This can include asking for personal and family medical histories and of any recent injuries. Further diagnosis may include sensation tests, a physical examination, and potentially x-rays or other imaging tests.

Treatment

Just as the range of causes varies widely, so do treatments. Some more common treatments are rest, ice packs, keeping pressure off the foot, orthotics and braces, medication for inflammation and pain, and surgery.
