Iwi'aʻaʻa: mall hiʻona a me ka hana

Iwi'aʻaʻa mea okoa kekahi ÿano waiwai o ka mea e kākoʻo lole i ua haku o ka iwi keena a me kona poe waena. Ke 'ole nā palapala collagen puluniu (iwi'ōpū mai) a me kekahi mau'okanikaʻole i huiʻia. Eia kekahi, iwi'aʻaʻa he lacunary-canalicular'ōnaehana oia hoi o ka pukapuka o microscopic lacunae a me ka canaliculi a me ka hoʻolako 'intraosseous pūnao.

Iwi aeee mea o ka ekolu ano: osteoclasts, osteoblasts a me osteocytes. Osteoclasts - he nui multinucleated keena o monocytic ka molekumu o, ka nui o ka a i a hiki i 190 microns. Mau keena e komo i loko o ka resorption (luku) o ka iwi a me ka cartilage. Ma lalo o physiological a reparative e noho o ka iwi resorption, osteoclasts lawe aku no hoi ia. Osteoclast ha awina mea pololei e kaukaʻi ma o ka nui o parathyroid hōmona, ka mahuahua hoʻololi kemikala o i entails ka ho'ā hope o ka osteoclast hana, e alakai ana i ka make ana o ka iwi.

Osteoblasts - e opiopio polygonal kupa iwi aeee 'ia i loko o kaʻili papa o ka iwi, a hoʻopuniʻia e ka lahilahi collagen microfibrils. O ka papa kuhikuhi hana o ka osteoblasts mea e synthesize extracellular'ōpū mai eiiiiiaiou - iwi collagen a me ka hooponopono ana mineralization.

Osteocytes, a ua hoonohonoho i loko o nā wahi i wāhiʻia i fusiform mnogootrostchatye oʻo iwi keena, hooponopono ana i pūnao intraosseous.

Aia he mau ke ano o ka iwi'aʻaʻa: lohi loa-puluniu, a me ka lau. Ma nā mākua, lohi loa-puluniu iwi'aʻaʻa aia i loko o na ami o ka puniu wale no, a iwi o na cii o IeIIeYOA i tendons, he amorphous a me kāna hana manoanoa laulau o ka collagen olona. I ka haku mele 'ana o lamellar iwi mai nā' iwi papa o ka mānoanoa o ka 4-15 microns osteocytes, walaʻauʻana waiwai a me ka wiwi collagen olona.

Iwi'aʻaʻa, e like me nā nā loko o ke kanaka kino ua waiho kokoke ana i na aku aat, a me nā maʻi. Pathogens aat i hiki ke hoʻolauna i loko o ka mea ma ke koko, oa. E. Ka hematogenous ala hele, i loko o ka hanana i ka hoʻomanawanui i purulent ipu ahi. Li nui o ka iwi 'aʻaʻa kapa osteomyelitis predisposing kumumea o ka i hiki e beriberi, trauma, luhi, ka huʻihuʻiʻana, a no laila, ma luna o. Ke kaumaha ma muli o ka nui a me ka mämä holo o ka osteomyelitis hoomaopopo maʻi, huʻi a me ka subacute ano o ka maʻi.

Ka hopena o ka lōʻihi hoʻoʻino iwi'aʻaʻa mea vascular blockage a me ka poe ilihune holo (thrombosis). No laila, nele o ka kino iwi'aʻaʻa hoʻomaka e uhai ia mertvet, a, me ia i kaʻilihune, he mea necrosis (necrosis) a me ka make ana o ka iwi'aʻaʻa. Eia hou, aia no he rejection o necrotic iwi, iaono? A me ka poho o ka palapala a me ke olakino iwi'aʻaʻa, i hana ka pela-kapaia sequesters.

Ke kumu nui no na la osteomyelitis (li nui o ka iwi 'aʻaʻa) e pyogenic koʻohune: streptococci, staphylococci a me ka pneumococci, a me ka intestinal, typhoid bacillus a me nā microbes. Aʻano o ka osteomyelitis noʻonoʻo hoʻoʻino maʻi e like me tuberculosis, iwi felon a me ka iwi.

Osteomyelitis lapaʻau mea, e luku aku i ka maʻiʻaʻai me antibiotics, a i wae pākahi ke kaumaha ma muli o ka 'ano o koʻohune. Antibiotics mau ma kahi o elua mahina. Nā lā mua o ka ai 'i ia ma ka Akala a palapala, ina eha lā i hana hou ua malama, i ka lāʻau' ua lawelawe intravenously paha mau pololei i loko o ka waena o ka osteomyelitis.
