What causes posterior ankle impingement?
The ankle joint is primarily composed of two bones, the tibia (shinbone) and a small bone between the shin and the heel, the talus. When the foot is pointed or flexed, the ankle is compressed at the joint. Pain can result if tissue becomes trapped between the bones. Posterior impingement, in the back of the ankle, is more common in ballet dancers and can be due to overuse, poor training techniques or an atypical bony protrusion at the back of the ankle.
What is Achilles paratenonitis?
Achilles paratenonitis is inflammation of the covering of the Achilles tendon, which connects the calf muscles to the heel bone. It can cause scarring that restricts the motion of the Achilles tendon. Achilles paratenonitis is caused by overuse or repeated movements and poorly fitted shoes. It is frequently seen in marathon runners.
Symptoms include tenderness, pain and swelling in the Achilles area. Symptoms are usually worse during activity.
Treatment consists of rest, pain relief, stretching exercises and changes in sports techniques and footwear to reduce stress on the tendon.Achilles paratenonitis is also known as Achilles peritendinitis, tenosynovitis or tenovaginitis.

What is os trigonum syndrome?
Os trigonum syndrome can be triggered by overuse and repetitive motion as well as by an injury, such as an ankle sprain. As the os trigonum is crunched between the ankle and heel bones, it pulls loose and the tissue connecting it to the talus is stretched or torn and becomes inflamed. The result is deep, aching pain in the back of the ankle that occurs mostly when pushing off on the big toe or when pointing the toes downward.
