Chirwere chinowanikwa chepfupa chemapfupa emasabolism. Izwi iri rinonzwisiswa seboka rezvirwere zvezvirwere zvinoratidzika nekuderera kwehuwandu hwemapfupa emapfupa paunenge uchigadzirisa. Muhuwandu hwevarwere, kukura kwehutano hwehutano kunobatanidzwa nehutano hwekukwegura (idiopathic osteoporosis). Icho chimiro chechirwere icho chinowanzoonekwa mumadzimai mushure mokutanga kwekumera, pamwe chete nevarume vakuru. Osteoporosis inogona kukonzerwa nezvimwe zviitiko, somuenzaniso, kutora zvakanyanya steroid nekudhakwa, chirwere cheshuga, hyperthyroidism.
Kurasikirwa kwefupa
Idiopathic osteoporosis inosangana nekurasikirwa kwema 3-10% emapfupa egore gore negore, uye izvi zvinokurumidza kuvakadzi kupfuura varume. Mutengo wekufambira mberi kwechirwere unogona kukanganisawo nezvinhu zvakadai semararamiro ekugadzirisa muviri, skeleton mashoma, basa rekuita, chimiro chekudya kwemahomoni (zvikurukuru estrogen). Osteoporosis idambudziko rakawandisa uye haigoni kuporeswa zvakanaka, saka zvakakosha zvikuru kuti zvionekwe pakutanga nekuongorora. Osteoporosis inowanikwa nehuwandu hwehuputi hwemapfupa, kunyange nekukuvara kwechidiki-somuenzaniso, kuwa kwechigarire kunogona kukonzera kuputsika kwechiuno. Izvi, zvakare, zvinotungamirira kune chirwere chinorwadza chirwere, huwandu hwekuchinja kusinganzwisisiki mumuviri weakakuvara, uyewo kuwedzera kukuru kwekutarisira kweutano. Nokudaro, kuonekwa kweasteoporosis pamusana pekutanga kune basa rinokosha zvikuru. Kupindira kwechipatara panguva yakakodzera kunokubvumira kusimamisa kana kuderedza kurasikirwa kwemapfupa emapfupa. Utano uye simba remasaga rinoenderana nehuwandu hwekukura uye kugadzirisa pfupa. Nhengo dzemafu dzine huwandu hwakawanda hwekasiki. Icho chiyero chake chinoshumira sechiratidzo chekufungidzirwa kwemapfupa emaminetsi emagetsi (BMD).
Bone yakagadzirwa
Kazhinji, mapfupa emasaga aya anosanganisira cortical (dense) (80%) uye spongy (spongy) (20%). Mumapfupa emutsara uyu chiyero chinoenderana 34% uye 66%. Sezvo kuvandudzwa kwepongemutema bone yakashata kunowanikwa kanomwe kanomwe kupfuura imwe yekortical, musana wechipfuva chiri munzvimbo inotambura, nehurumende iyo inokwanisa kutonga kuwanda kwemapfupa emapfupa.
"Hove" vertebrae
Kunyangarika kwekutenderera kwetebeculae. Iyo yakasara verbeculae inokonzera chirevo chakatsanangurwa chemiviri yemitema. Kurasikirwa kwetatbeculae kunotungamirira kune kuwedzerwa kwakasimba kwezvakazara zvekortical layer pa roentgenogram, iyo inoumba chimiro chechimiro chakakomberedza miviri yakasviba. Computer tomography yechiparadzi yepamusoro yekutengesa kweMKT mumutsetse wespongy we vertebrae inogona kushandiswa computed tomography. Iyi nzira inoita kuti zvibvirire kubvisa kubva pakudzidza dense veronabra yakaoma, yakagadzirwa nekuumbwa kweasteophytes neArthrosis I mukugadzirwa kwekukwegura kwepanyama. Dual-simba X-ray absorptiometry (DRL) ndiyo nzira inowanzozivikanwa yekugadzirisa. Kunyange zvazvo pasina urongwa hwehutano hwehutano hwehurumende, shanduro yakadaro inokurudzirwa kuvarwere vane nhoroondo yemhuri, kusadya kwakakwana kana kusakanganiswa muhuongorori hwemafirimu. DRA inonetswa nevarwere nyore nyore. Panguva yekudzidza, murwere anorara akanyarara pamubhedha kwehafu yeawa. Kunyanya kuderera kwema-ray-ray kunoshandiswa. Kuyera kwemafupa emapfupa kunobva pakugadzirisa musiyano muhuwandu hwekugadziriswa kwemaviri e-X-ray. Kuti uwane huwandu hwehuwandu hweBDD, migumisiro yeDLL inoshandurirwa muhuwandu hwemabare. Zvadaro zviratidzo zvinofananidzwa nehutano hwakanaka hwekupiwa kwezera remakore uye rudzi rwemarudzi. Ruzivo rwakadaro, rwuri mufananidzo wakajeka, runogona kushandiswa kwekuongorora kwegore negore kwemasimba ekurasikirwa kwefupa. Iye zvino tinoziva kuti osteoporosis inobatwa sei mukutanga.
