A<unk>  (also known as a heel<unk>  is a bony outgrowth from the<unk>  tuberosity (heel bone).<unk> s are typically detected by x-ray examination. It is a form of exostosis. When a foot is exposed to constant stress, calcium deposits build up on the bottom of the heel bone. Generally, this has no effect on a person's daily life. However, repeated damage can cause these deposits to pile up on each other, causing a<unk> -shaped deformity, called a<unk>  (or heel)<unk> . An inferior<unk>  is located on the inferior aspect of the calcaneus and is typically a response to plantar fasciitis over a period, but may also be associated with ankylosing spondylitis (typically in children). A posterior<unk>  develops on the back of the heel at the insertion of the Achilles tendon. An inferior<unk>  consists of a calcification of the calcaneus, which lies superior to the plantar fascia at the insertion of the plantar fascia. A posterior<unk>  is often large and palpable through the skin and may need to be removed as part of the treatment of insertional Achilles tendonitis.
