Calcinosis cutis is an uncommon condition marked by calcium buildup in the skin and subcutaneous tissues. Calcinosis cutis can range in intensity from little nodules in one area of the body to huge, crippling lesions affecting a vast portion of the body. [1] Five kinds of the condition are typically distinguished: calciphylaxis, idiopathic ...
Dystrophic calcification (DC) is the calcification occurring in degenerated or necrotic tissue, as in hyalinized scars, degenerated foci in leiomyomas, and caseous nodules. This occurs as a reaction to tissue damage, [ 1 ] including as a consequence of medical device implantation. Dystrophic calcification can occur even if the amount of calcium ...
A calcaneal spur (also known as a heel spur) is a bony outgrowth from the calcaneal tuberosity (heel bone). [ 1 ] Calcaneal spurs are typically detected by x-ray examination. [ 2 ] 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.
Calcification is the accumulation of calcium salts in a body tissue. It normally occurs in the formation of bone, but calcium can be deposited abnormally in soft tissue, [ 1 ][ 2 ] causing it to harden. Calcifications may be classified on whether there is mineral balance or not, and the location of the calcification. [ 3 ]
Haglund's deformity is an abnormality of the bone and soft tissues in the foot. An enlargement of the bony section of the heel (where the Achilles tendon is inserted) triggers this condition. The soft tissue near the back of the heel can become irritated when the large, bony lump rubs against rigid shoes.
Most bone surfaces express no new bone formation, no tetracycline uptake and no mineral formation. This strongly suggests that facilitated or active transport, coordinated across the bone-forming group, is involved in bone formation, and that only cell-mediated mineral formation occurs. That is, dietary calcium does not create mineral by mass ...
Osteophyte formation has classically been related to sequential and consequential changes in such processes. Often osteophytes form in osteoarthritic joints as a result of damage and wear from inflammation. Calcification and new bone formation can also occur in response to mechanical damage in joints. [5]
Calcaneal spur (heel spur) is a small calcified bone extension located on the inferior aspect of the calcaneus or on the back of the heel at the insertion of the Achilles tendon. The condition is typically a response to plantar fasciitis over a period of time.
