Calcaneocuboid joint: The joint located in the foot between the calcaneus bone and the cuboid bone. It is a gliding type of joint. The ligaments that serve to support and strengthen this joint are called the capsular, dorsal calcaneocuboid, bifurcated, long plantar, and plantar calcaneocuboid ligaments.
- Calcaneal spur
A bony spur, also known as a heel spur, that projects from the back or underside of the heel bone (the calcaneus) and that may make walking painful. Calcaneal spurs are associated with inflammation of the Achilles tendon (Achilles tendinitis), and cause tenderness and pain at the back of the heel, which is made worse […]
Calcaneus: The heel bone, a more or less rectangular bone at the back of the foot. Also known as os calcis.
- Calcific bursitis
A bursa is a thin fluid-filled sac that reduces friction forces between tissues of the body. Chronic (repeated of long-standing) inflammation of the bursa (bursitis) can lead to calcification of the bursa. This is referred to as “calcific bursitis.” The calcium deposition (calcification) can occur as long as the inflammation is present.
- Calcification, nonarteriosclerotic cerebral
Calcification, nonarteriosclerotic cerebral: This condition described in 1930 by T. Fahr (and therefore called Fahr syndrome) is a genetic (inherited) neurological disorder characterized by abnormal deposits of calcium in certain of areas of the brain (including the basal ganglia and the cerebral cortex). Symptoms may include motor function deterioration, dementia, mental retardation, spastic paralysis, dysarthria […]
Calcinosis: An abnormal deposit of calcium salts in body tissues. Examples include the calcifications in the skin from scleroderma and in the muscle from polymyositis.
