calcium hydroxyapatite deposition disease


(A) etiology
Tendon within the joint next to the basic calcium phosphate crystal deposition is due to tendon injury was considered a secondary result of ectopic calcification, and therefore on the classic description of the disease often with shoulder overuse or trauma associated with, but bilateral lesions or calcification of the joints next to the case is not uncommon, is now clearly secondary to the disease can be the body of calcium and phosphorus metabolism in a number of underlying diseases, such as chronic renal failure, diabetes, rheumatism, thyroid or parathyroid disease and tumors, which are secondary to uremia, alkaline phosphate deposition disease is more common, patients often can occur with metastatic calcification of soft tissue, and is often associated with joint inflammation or joint next to the inflammation, also often can be found in other types of crystals, such as calcium phosphate crystals of calcium oxalate crystals and coke, etc., which also tips of secondary alkaline phosphate deposition disease with abnormal calcium and phosphorus metabolism are closely linked, but the predilection sites of the disease seems no obvious underlying disease such between genetic factors related to the disease or HLA typing of research is inconclusive so far.
(B) of the pathogenesis
1. Basic structure and function of calcium phosphate crystals of basic calcium phosphate crystals is the general term for a large class of crystals, the normal deposition of bone tissue in the major minerals calcium hydroxyapatite is a basic, it is for the formation of normal bone, dentin and enamel, it is essential, but apparently extracted from normal bone alkaline phosphate and minerals extracted from the lesions in the composition is significantly different.
The chemical formula of hydroxyapatite is Ca10O (PO4) 2OH, the formula of the hydroxyl can be replaced by other groups, in particular, was replaced by carbonate in normal bone tissue, often part of the carbonated hydroxyapatite, about 50nm in a tiny grain as the main mode of existence, sometimes irregular small grains the transition through some intermediate form (such as octacalcium phosphate) and the formation of larger crystals, the deposition of calcium in the joints next to the stove , often it is easy to see under the light microscope showed a large accumulation of multi-focal distribution of the crystals, these crystals accumulate collagen fibers lesions often isolated from each other in the transmission electron microscope can also see a similar scenario: the form of pellets one accumulated crystal-like

Basic calcium phosphate crystal deposition disease in whic
h the performance and how to diagnose?
Clinical manifestations】 【
Basic calcium phosphate crystal deposition disease more common in the elderly, its prevalence rate increases with age, mostly affects the large weight-bearing joints, most commonly the shoulder bursa, tendons, ligaments, to the right as a, followed by the other hip, elbow, wrist and knee, in the clinical setting, when the basic calcium phosphate crystal deposition in different parts of the body can cause different symptoms or syndrome, as shown in Table 1.
,
First, the joint next to the inflammation of calcific
Calcified joint next to the inflammation without any clinical manifestations usually can, but often acute onset, about 70% of patients with calcification of the joint next to the inflammation around the shoulder joint, some attacks may be secondary to trauma, but most patients There is no incentive or before the onset of aura, onset of symptoms typical of sudden pain, often described as
