Calcific tendinitis is a common condition where deposits of calcium phosphate form in a tendon, sometimes causing pain at the affected site. Deposits can occur in several places in the body, but are by far most common in the rotator cuff of the shoulder.
Calcific bursitis refers to calcium deposits within the bursae. This most occurs in the shoulder area. The most common bursa for calcific bursitis to occur is the subacromial bursa. A bursa is a small, fluid-filled sac that reduces friction, and facilitates movements between its adjacent tissues (i.e., between tendon and bone, two muscles or ...
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]
An enthesophyte, consisting of calcification deposits within the Achilles tendon at its calcaneal insertion. The Achilles tendon is wider than normal, further suggesting inflammation . Enthesophytes are abnormal bony projections at the attachment of a tendon or ligament . [ 1 ]
However, repeated damage can cause these deposits to pile up on each other, causing a spur-shaped deformity, called a calcaneal (or heel) spur. [ 3 ] 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 ...
Milwaukee shoulder syndrome (MSS) (apatite-associated destructive arthritis/Basic calcium phosphate (BCP) crystal arthritis/rapid destructive arthritis of the shoulder) [1] is a rare [2] rheumatological condition similar to pseudogout, associated with periarticular or intra-articular deposition of hydroxyapatite or basic calcium phosphate (BCP) crystals.
Calcium is used to make calcium carbonate (found in chalk) and calcium phosphate, two compounds that the body uses to make teeth and bones. This means that too much calcium within the cells can lead to hardening ( calcification ) of certain intracellular structures, including the mitochondria , [ 2 ] leading to cell death.
Stage 1 involves the formation of calcium deposits both inside and outside the vascular smooth muscle cells which compose the tunica media. Calcification outside of the vascular smooth muscle cells are commonly associated with damage to elastic fibers in the extra-cellular matrix. These calcium deposits also develop on the internal elastic ...
