Iwi densitometry a me ka osteoporosis - kekahi manawa e loaʻa mai ma mua e pili ana i ka maʻi

Osteoporosis - pathology, ma i na iwi o lakou i lilo kalipuna, ma laila lilo ana i brittle. Inā he mea i ka meaʻuʻuku traumatic ololi ka mea, ke ino a wāwahi i. Manaʻo kuhihewa manaoio i ka maʻi i loko o ia lŘlŘ kanaka nona ke kino i loko o ka lawa ponoʻole nui o ke kalipuna. Kēia mea,ʻaʻole oiaio. Osteoporosis? Acaeoey? A me ka oi o ke kumumea nā kumumea i loko o kaʻai. Ke kumu no ka mahuahua iwi fragility Ua lawa omo o ka kalipuna iwi a me "washout".

Ke etiology o osteoporosis

I ka pa apŘ o ka iwi hilinaʻi nui ma luna o ke dala o ke keka hormones. I na kanaka, testosterone oi ma mua o na wahine, no laila lākou mau iwi, ua nui ka pūhaka, a ikaika. E like me ka hopena, osteoporosis ua pinepine diagnosed i na wahine, o ka oi aku ma ka menopause, no ka mea, ma ia manawa ua hoemi me ka nui loa o ka pae ana o hormones.

I waena o nā kumu, ka mea e e kaulana hypodynamia osteoporosis, nele o ka wikamina D, inu i ka waina, e uwahi ana, imua o ka maʻi maʻi (mimikō, thyroid lesions, maʻi ake maʻi a me nā konāhua).

Pehea e hōʻike osteoporosis?

Inā he kanaka i olelo mai luhi a me ka iwi eha, loli ma kulou a me ka ana, 'lauoho poho a me ka mea hōʻemi o na niho, e like me pinepine fractures, ka mea, ua? Aeiiaiaoaony e e densitometry. Kēia mea he poe ola, a me ka loa painless ho'āʻo e leie aku, e hoakaka, a ana i ka lilo o ka iwi nuʻa a me ka mea pōhaku kamepiula, e hookupaa aku a loiloi i ka pilikia o fractures. 'O kēia ka loa ikepili koʻikoʻi loiloi hana no kakahiakaʻike, o ka osteoporosis.

Ke ae pā o ka densitometry ua candling iwiʻike makaʻole X-kukuna. Ma keia hihia, e hoʻohana i ka haʻahaʻa mahele lāʻau o ionizing pāhawewe hāʻawi i loko o ka palapala o nā ikehu lua i pele, e leie aku no ka hoʻokēʻai a me ka pololei nana.

Ua Ua kaulana ia iwi densitometry wehewehe aku ma ka pāhawewe mahele lāʻau, a ua hoemi ia a hiki i ka palena iki (ia mea emi o 1/10 o ka mahele lāʻau i nā mea maʻi i loaa i ka maʻamau pahu radiography).

I ka wā o ka densitometry

Nāʻikepili no keia anamanaʻo mea i ka penei Hawaii:

• kakahiaka nui menopause a menopause, i ia lŘlŘ i loko o na wahine kēia cessation o menstruation;
• i ke alo o kaʻaʻa puʻuwai ole;
• maʻi ake maʻi;
• lōʻihi-ʻia lapaʻau me glucocorticoids;
• nutrient malabsorption maʻi pale, i hiki aku ai i kalipuna deficiency;
• iwi densitometry ua i mālama 'ia ma ke alo o rheumatoid arthritis, hyperparathyroidism a me ka hyperadrenocorticism e like me ma ka hypothyroidism a me ka mimikō.

Inā he mau fractures me ka nīnūnē trauma, ia mea no hoi he PAaIEN no ka anamanaʻo. Ua Ua manaoio ana i ka 'aʻe' ana i ka pono o ka iwi i loko o osteoporosis ho'ēmi i kā ke ola expectancy o nā mea maʻi e oi ma mua o ka maʻi 'aʻai, no laila, i ka' eleu ka loaʻaʻana o ka maʻi he'āina nui. It E e kaulana ia i loko o kekahi mau hihia hōʻike nō ia o ili mai iā ia ano o keia pathology.

Iwi densitometry: Key

Aia i kela ano no kaʻimiʻana osteoporosis, akā, i ko lākou hoʻohana ka loa i kaupalena '. Penei, likeʻole ka hoʻololi 'ana o ka MRI e pipiʻi, laupaʻi Me tomography haawi i ka kiʻekiʻe mahele lāʻau o ka pāhawewe, ka study o pili biochemical indices o ka iwi pūnao wehewehe aku ma ka nui likeʻole i loko o hoʻokonukonu ka ikepili, a me ka hoʻomanawanui Kahalaopuna discomfort ka wā o ka biopsy iwi. I ka wā o kaʻike, o ka osteoporosis, densitometry o ka loa hanohano ina hana like.

Hoʻohana 'ia ka papa kuhikuhi' ana i kūpono ekolu mea i ua ulu manaʻoi no ka ka loaʻaʻana o kēia maʻi.

• X-Ray absorptiometry;
• Ultrasound densitometry;
• ʻike ākea Me tomography (mai ka nui drawback - Aʻole 'ae' ia Loiloi i ka ano o ka iho iwi iwi).

No ka pono kīvila o ka noiʻi iaoia a me ka pololei helu o nā hualoaʻa lawe i loko no o ka 'o lapaʻau hoike ana. No hoi ia i loko, no ka pili PalekanaEND_LINK ana hoʻohālike.

Nā loina o ka loiloi 'ana o densitometry hualoaʻa

E wehewehe i ka anamanaʻoʻikepili loaa ma hope o ka makahiki "osteopenia" 'ole hoʻohana "osteoporosis". Ka mea, e ole e noʻonoʻo me ka lapaʻauʻike, akā, wale me he symptom i hiki pu kekahi skeletal lesion me ka hōʻemiʻana nuʻa. It E ke kaulana i ua ole lawe mai iwi densitometry no ka pololeiʻike, a me ke kuhikuhi i nā mea maʻi i kamepiula o ke fracture.

Me keia lako polokalamu lako a (densitometer) hoʻohālikeʻana i nā hualoaʻa loaa, a me ka wae hōkeoʻikepili, a me ka like o statistically. Ua nānā 'ia ma ka helu o ka paʻamau deviations ka oukou koho i ka inoa o T-ho'āʻo (hoʻohana no ka Hoʻohālikelike maikaʻi a me ka mea opiopio o ka ia ke keka me ka hoʻomanawanui kanaka) a Z-ho'āʻo (no ka nane, i ka pae ana o kanaka o kūpono makahiki, ke keka, a kaumaha).

Inā ka T-hoao ana mea i oi aku mamua o 2,5 SD, ua hoʻopili like i ka osteopenia, ina na nā hualoaʻa ma lalo o kēia aka, i kekahi olelo o ka osteoporosis. Mau loina i manaoia "paepae." Kēia E e noʻonoʻo ai i ka pololei i ka hoolike ana o ka densitometry hualoaʻa.

X-Ray densitometry

Technically, me ka hiki e makaikai i ka hapanui o nā iwi ke kōkua o ka X-Ray irradiation. Ana e paa ana ia spine densitometry (kona lumbosacral spine) a me ke ki, kahi loa ka ulu 'fractures e osteoporosis. No hoi kau i ka pa apŘ o ka iwi'aʻaʻa'ūhā, a forearm densitometry a pana aku au i ke kino holoʻokoʻa. Ua apono 'keia hookolokolo ana, e hooholo i ka maʻiʻo o nā minelala hao ma wae wahi o ke kino a ma ke kino.

I ka hala no ka loiloi 'iwi nuipa a me ka mea pōhaku maʻiʻo o ka hui i hoʻohana absorptiometry kālaiōewe iaoia, ka loina o ka i ninoieo i kaʻilikai i ka gamma huna a me ka loiloi' i ke degere o ko lākou omo. An nui keakea ana ia he anamanaʻo mea he nui pāhawewe waiū. A laila, hoomaka ae la e hana mau-photon m-Ray absorptiometry, a ua loa ikepili koʻikoʻi, a emi nā palapala i nā mea maʻi. I ka lā, ka mea hiki ke kōkua kuhikuhi wale 2-3% o ka iwi poino, no laila, i kēia anamanaʻo hiki ke hoʻohana no ka loiloi 'na wahine ma ka menopause no kakahiaka ka loaʻaʻana o ka osteoporosis.

ultrasound densitometry

Kēiaʻano o ka anamanaʻo ua lawelawe 'ia e Loiloi i iwi ikaika. Kēia mea i loko o ka mooolelo o ka pa apŘ, microstructure a me ka elasticity, e like me ka mānoanoa o ka cortical, ahu iho. An nui ia Morohiha o ia he anamanaʻo - i ka wa e kaawale aku o ka pāhawewe waiū. E noonoo pono i ka maluhia o keia ina hana, ka mea hiki ke hai hou me kekahi kapu.

Ua pono e mai la oia ia ia i ka densitometry ua ma muli o ka hiki ana o ultrasonic nä hawewe kani ma ka ili o ka iwi, a hoʻopuehuʻia i loko o ka iwi'aʻaʻa. Ma keia hihia, he mea hiki e hooholo i ka elasticity, nuʻa a me ka oolea o ka iwi.

It E e hoʻomaopopo i ka mea kani ultrasonic nä iwi densitometry ua hoʻohana wale no ka ninaninau ana i ka meaʻike ākea iwi. Loa pinepine, keia iaoia hookolokolo aku la ia i ke kuekue wawae a me ka tibia, patella, a me phalanges. Ka hapa nui o nā mea kau i ka mämä holo o ke kani ultrasonic propagation a attenuation, i Hōʻike ole wale ma iwi nuʻa, akā, no hoi ma o ka loaʻa nui o ke anakahi iki paha trabecular.

ka hopena

Nānā 'ole o ka Pehea osteoporosis ua malamaia lakou nei, (i loko o ka palapala o ka symptom a maʻi), densitometry e leie aku e hooholo i ka pilikia o ka fracture. Ua hoʻomanaʻoʻia ai ia i ka poʻe uʻi a o ke anamanaʻo wahi mea loa nui, no ka mea, na densities o mineralized iwi paha i ole ia i ka ia no ka iwi holoʻokoʻa.

E hana i ke koho pono, e pono e ike i ka kēia lauana.

• trabecular waiwai loli ma menopausal maʻi pale ole hypogonadal steroid imbalance;
• preferential poino i cortical iwi ua malamaia ma senile, hyperthyroid, diabetic osteoporosis;
• ina o ka hoʻomanawanui i loko o kamaliʻi a adolescence e hoʻomōhala ana i ka maʻi i interferes me ka ulu ana o ka iwi, e diagnosed i nā iwi me systemic mā. Ka mea, i hele pu me ia e poho ana i nā iwi papa.

Oe e ike i ka loaʻa o ke au o ka "mahuahua ana" osteoporosis o ka iho iwi i konaʻike ākea mau mea, no lailaʻoe e mua nana i ka vertebrae no ka wanaʻaoʻike. Free densitometry, Eia naʻe pohihihi keia, mai ka anamanaʻo ua ana mālama 'ia i loko o kekahi nā keʻena lāʻau lapaʻau, a pono kūpono lako a pan.
