Tsanangudzo yeOsteoarticular Transfer System
Nzira yeAATS, chidimbu chemaosteoarticular transfer system, inzira yekuvhiya inoshandiswa kurapa kukanganisa kwepaltilage. OATS ndeye nzira imwe yevamwe vanoshandiswa kugadzirisa dambudziko iri; rudzi rwemitiro inonzi "mosaicplasty".
A mosaicplasty inoshandisa martila kubva munzvimbo dzisina kufanira dzomubatanidzwa uye inoita chikafu ichi panzvimbo yakakanganiswa.
Iyi nzira yekushandura inongoshanda chete mukurapa kwekukanganiswa kwekodtilage. Izvi zvinoreva kupararira kwakawanda kwekatetila inowanikwa mumamiriro ezvinhu seysteoarthritis haigoni kurapwa ne mosaicplasty. Iyi kurapwa inongoshandiswa chete kune nzvimbo dziri kure dzomusango wegasiti, kazhinji zvinowanikwa kusvika 10 - 20 mm muhukuru. Izvi zvinowanzoonekwa kuvarwere vaduku (vasati vava nemakore makumi mashanu) vanoona kushungurudzika kwavanobatana navo.
Uyewo Anozivikanwa Se: osteoarticular transfer, mosaicplasty, Osteochondral Autograft Transfer System
Ndeipi Nzira yeOATS Yakaitwa?
Kazhinji chiremba anovhiya achaona rudzi urwu rwekuita, asi kana x-ray kana arthroscopic kuongorora zvinoratidza uchapupu hwehuwandu hwehutakisi hwakapararira, nzira yeAATS haigoni kuitwa. Chikonzero ndechokuti nzira yeOATS haibatsiri varwere ava.
Nzira yeAATS, yakagadzirwa neArthrex corporation, ndiyo imwe yeropaicplasty.
Zviduku "zvikwata" zvehututika uye zvakabviswa munzvimbo dzekubatana apo muviri unogona kuita pasina teteti, uye izvi zvinoshandiswa kune zvakakanganiswa zvekubatana. Arthrex corporation ine chinyorwa chakanyoreswa cheOATS Osteochondral Autograft Transfer System.
Inobatsira Sei Nzira dzeOATS?
Chidzidzo chevarwere vanokwana 96 vakafananidza nharo yeOATS kune microfracture kurapwa kwemavara ega ega marticle.
Varwere vakanga vari pakati pemakore 30-32 uye vakateverwa gore negore kwemakore mashanu mushure mekuvhiyiwa. Vakawana hutano hwakafanana nehutano nemabvi ekushanda kwezvinhu zvose. Asi pakanga paine musiyano mukukwanisa kuchengetedza hukuru hwemutambo webasa, uye OAT mosaicplasty iri nani kudarika microfracture.
Nzira yeAATS inogadzirwa sei?
Shandisa OATS Rimwechete (Osteochondral Autograft Transfer System) yakagadzirwa naArthrex inoshandiswa mukugadzira uku. Chikwata chokuvhiya chinosanganisira mucheki anogamuchirwa, mucheki anopa zvipo, anogadzirisa tsvimbo, tamp, mabhii ekutakura bhutu uye chinonzi extruder.
Murwere ndiye anopa uye anogamuchirwa, ane chirwere chine utano uye mapfupa ayo akachekwa kubva kune imwe nzvimbo iri pedyo pamwe chete kuti adzokere munzvimbo inenge yakakanganiswa nekatekete. Ikosi yeAATS inopa mupiro yakagadzirirwa pamusoro pomunhu anopa mhepo uye yakarova nemarlet kusvikira yava tamp 15 mamita mukati memupi wemupiro. Iyo michina inobva yashandurwa kuitira kuti ivhunze hutumbi uye yakabviswa.
Iye zvino chitubu chinogadzirwa pamusoro pechinhu chaiva nehutachiona hunokonzerwa necartilage huchava hukuru hwakakodzera hwekugamuchira ipulagi. Mumwe muchengeti wehomwe anogadziriswa uye anonamatira kuti abvise paki kuti aite uswa hwakakodzera nekudzika kwegomba.
Chirongwa chekufananidza chinoshandiswa kuyera nekudzika uye chero zvigadziriswa zvinodiwa zvinogadzirwa kuti zvigadzirire iyo kubatanidzwa.
Kana yatova yakagadzirira, kubatanidzwa kwehutachi bhutoni hunoiswa pamuromo wechipikisi chikwata uye chakatumirwa mukati maro. Tsvina inobva yasungirwa kuti igadzire kubatanidzwa muhomwe. Chiremba anovhiya anogona kuzadza nzvimbo dzezvipo ne hydroxyapatite tsvimbo uye angashandisa gorosi glues kuti aise chisimbiso chakagadziriswa.
