A calcaneal spur (or heel spur) is a small osteophyte (bone spur) located on the calcaneus (heel bone). Calcaneal spurs are typically detected by a radiological examination (X-ray).
An inferior calcaneal spur 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 calcaneal spur develops on the back of the heel at the insertion of the Achilles tendon.
An inferior calcaneal spur consists of a calcification of the calcaneus which lies superior to the plantar fascia at the insertion of the plantar fascia. A posterior calcaneal spur is often large and palpable through the skin and may need to be removed as part of the treatment of insertional Achilles tendonitis.[1]
