Tanthauzo la Osteoarticular Transfer System
Njira ya OATS, chidule cha osteoarticular transfer system, ndi njira yopaleshoni yomwe imagwiritsidwa ntchito pochiza zofooka za khungu. OATS ndi njira imodzi yomwe amagwiritsidwa ntchito kuti athetse vutoli; mtundu wa ndondomeko amatchedwa mosaicplasty.
Maselo otchedwa mosaicplasty amagwiritsira ntchito katemera kuchokera kumalo osasunthika omwe amagwiritsidwa ntchito ndipo amachititsa kanyumba kake kumalo owonongeka.
Njira imeneyi ndi yothandiza kwambiri pochiza matenda owonongeka. Izi zikutanthauza kuti kuwonongeka kwa cartilage kumawoneka ngati mitsempha ya osteoarthritis sitingathe kuchiritsidwa ndi mosaicplasty. Mankhwalawa amagwiritsidwa ntchito kumadera ena okhaokha omwe amatha kuwonongeka kwa karotila, kawirikawiri amangopitirira 10 - 20 mm kukula. Kuwonongeka kotereku kumawoneka kwa odwala achinyamata (osakwana zaka 50) amene amavutika ndi zovuta zawo.

Kodi Ndondomeko ya OATS Idachitika Liti?
Kawirikawiri dokotalayo amalingalira njira iyi, koma ngati x-rays kapena kupenda kwa nyamakazi ikusonyeza umboni wa kuwonongeka kwa karoti, machitidwe a OATS sadzachitika. Chifukwa chake n'chakuti ndondomeko ya OATS siidzathandiza odwalawa.
Njira ya OATS, yopangidwa ndi Arthrex corporation, ndi mtundu umodzi wa mosaicplasty.
Mitundu yaing'ono yamaguluti ndi kuchotsedwa kumalo amodzi kumene thupi lingathe kuchita popanda kagawoti, ndipo izi zimasunthira kumalo owonongeka. Arthrex corporation ili ndi chizindikiro cholembedwa kwa OATS Osteochondral Autograft Transfer System.
Kodi Ndondomeko za OATS Zimapindula Motani?
Kafukufuku wa odwala 96 anayerekezera ndondomeko ya OATS ndi mankhwala ochepa omwe amagwiritsidwa ntchito kuti apatsidwe matendawo a knee okhaokha.
Odwala anali pafupifupi zaka 30-32 ndipo ankatsatiridwa chaka ndi chaka kwa zaka zisanu pambuyo pa opaleshoni. Anapeza moyo wathanzi wofanana ndi zotsatira za mawondo a njira zonse ziwiri. Koma panali kusiyana kwakukulu pokhala ndi masewera apamwamba a masewera, ndi OAT mosaicplasty kukhala yabwino kuposa microfracture.
Kodi Ndondomeko ya OATS Idachitidwa Bwanji?
OATS Single (Osteochondral Autograft Transfer System) yomwe imagwiritsidwa ntchito ndi Arthrex imagwiritsidwa ntchito mu njira yopaleshoniyi. Chophimbacho chimaphatikizapo wokolola wobwezeretsa, wokolola wopereka ndalama, wogwiritsira ntchito ndondomeko, ndodo, yobweretsera pulogalamu yamtengo wapatali ndi phulusa lakuya.
Wodwalayo ndi wothandizira komanso wothandizira, ali ndi kathyola kathyola ndi mnofu wambiri womwe umatulutsidwa kuchokera kufupi ndi malo ophatikizirana kuti apitidwe kumalo omwe ali ndi vuto la khunyu. Wokolola Wopereka OATS ali pa malo operekera ndalama ndipo akugunda ndi mallet mpaka atapangidwira mamita 15 m'dothi lopereka. Mkonziwo umasinthidwa kuti ukolole pachimake ndi kuchotsedwa.
Tsopano thumba limapangidwira pamwamba lomwe linali ndi chilema chachikulu cha cartilage chomwe chidzakhala kukula kwake kulandira pulagi. Wokolola ozilandila amalowetsa mkati ndi kupotoka kuti achotse pulagi kuti apange kukula kwake ndi kuya kwake kwa dzenje.
Kugwiritsa ntchito ndodo kumagwiritsa ntchito kuyesa kuya kwake ndipo kusintha kulikonse kofunikira kumapangidwira kukonzekera kubzala.
Mukakonzeka, phukusi loyambitsirana limayikidwa pamilomo ya wolandira chojambulidwa ndikulowetsamo. Kenaka kamangidwe kamene kamakumbidwa kuti kakhale pansi pazitsulo. Dokotala wa opaleshoni akhoza kudzaza malo opereka ndalama ndi hydroxyapatite ndodo ndipo angagwiritse ntchito tizilombo toyambitsa matenda kuti asindikize chingwe cholandira.
