what is a calcaneal spur
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). When a foot bone is exposed to constant stress, calcium deposits build up on the bottom of the heel bone. 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.
