Most people have never heard of an os trigonum and do not know if they have one or not. That is because the os trigonum is an extra bone in the foot that is present in only 20% of the population. In most cases, this extra bone goes unnoticed. An os trigonum typically forms during childhood and, in most cases, fuses with the talus bone. But if it remains separate, complications can arise with overuse or trauma. The result is termed os trigonum syndrome. Activities requiring frequent ankle flexion, like ballet dancing or running, can contribute to its development. Also, an ankle injury that forces the foot into excessive plantar flexion, in which the toes are pointed downward, can lead to what is termed a nutcracker injury. It is caused when an os trigonum is compressed between the ankle and heel bones. Symptoms include pain at the back of the ankle, worsened during activities such as excessive toe pointing or in the push off phase while walking. Tenderness upon touching the affected area, swelling due to soft tissue inflammation, and the presence of a palpable lump near the Achilles tendon are characteristic signs of os trigonum syndrome. If you are experiencing pain in the back of the heel, it is suggested that you make an appointment with a podiatrist who can determine what the cause is, and suggest appropriate treatment.

Causes of Heel Pain

Heel pain is often associated with plantar fasciitis. The plantar fascia is a band of tissues that extends along the bottom of the foot. A rip or tear in this ligament can cause inflammation of the tissue.

Achilles tendonitis is another cause of heel pain. Inflammation of the Achilles tendon will cause pain from fractures and muscle tearing. Lack of flexibility is also another symptom.

Heel spurs are another cause of pain. When the tissues of the plantar fascia undergo a great deal of stress, it can lead to ligament separation from the heel bone, causing heel spurs.

Why Might Heel Pain Occur?

• Wearing ill-fitting shoes                  
• Wearing non-supportive shoes
• Weight change           
• Excessive running

Treatments

Heel pain should be treated as soon as possible for immediate results. Keeping your feet in a stress-free environment will help. If you suffer from Achilles tendonitis or plantar fasciitis, applying ice will reduce the swelling. Stretching before an exercise like running will help the muscles. Using all these tips will help make heel pain a condition of the past.
