Chondrocalcinosis articularis Section L Clinical and radiological study.

Morphological study of articular cartilage in pyrophosphate arthropathy. (Chondrocalcinosis articularis or calcium pyrophosphate dihydrate crystal deposition diseases).

[Chondrocalcinosis and hypomagnesemia: clinical and radiological progression].

Hypomagnesemia is a rare secundary metabolic disorder associated with calcium pyrophosphate dihydrate cristal deposition disease in joint structures and may cause asymptomatic chondrocalcinosis (linear calcification of cartilage), pseudogout, and chronic arthropathy. We report 2 young men with relapsing acute knee monoarthritis with chondrocalcinosis and hypomagnesemia. After follow-up clinical...

Destructive arthropathy in chondrocalcinosis articularis.

It is now well recognized that idiopathic chondrocalcinosis articularis, as well as being associated with acute episodes of pyrophosphate arthropathy, may lead to premature degenerative changes in the joints involved. Some workers have also made occasional reference to the presence of juxta-articular osteolytic lesions (McCarty, Kohn, and Faires, 1962; Currey, 1970.) More recently there have be...

Pyrophosphate arthropathy--recent clinical advances.

It is now 20 years since McCarty et al. identified calcium pyrophosphate dihydrate (CPPD) crystals in synovial fluid from patients with acute arthritis and radiological chondrocalcinosis.' CPPD crystals were subsequently shown to be inflammatory both in vivo and in vitro2 and their causal role in joint disease, reflected by the term 'CPPD crystal-induced synovitis', was readily accepted. Cadave...

New knowledge of chondrocalcinosis.

There are three varieties of cartilage-hyaline, elastic, and fibrocartilage. Hyaline cartilage is the precursor of bone. In the adult it is mainly found at bone ends, forming the load-bearing surface of synovial joints. Extra-articular fibrocartilages such as those of the trachea and ribs often calcify with advancing age. Articular cartilage, however, usually remains free from mineral deposits....
