Katswiri wochotsa nyama m'chiuno wotchedwa Ava adachitidwa opaleshoni yachiwiri yobwezeretsa chiuno ndi thandizo la madokotala a ziweto aku Texas A&M University, kukonza kotsogozedwa ndi computed tomography (CT) ndi ukadaulo wosindikiza wa 3D. Kenako bwererani ku kuthamanga ndi kusewera ndi banja lanu.
Pamene ziwalo ziwiri za m'chiuno zomwe Ava adalandira ali mwana wagalu zinatha mu 2020, madokotala a ziweto aku Texas A&M anachotsa ziwalo zakalezo ndikusintha ndi zatsopano, pogwiritsa ntchito mapulani otsogozedwa ndi CT, zitsanzo za mafupa zosindikizidwa mu 3D komanso opaleshoni yoyeserera kuti atsimikizire kuti opaleshoniyo ikuyenda bwino komanso yopanda ululu.
Agalu ambiri sachita opaleshoni ya THR (total hip replacement (THR)) kanayi pa moyo wawo wonse, koma Ava nthawi zonse wakhala wapadera.
“Ava anabwera kwa ife ali ndi miyezi pafupifupi 6 ndipo tinali makolo olera agalu omwe tinkakhala ku Illinois,” anatero mwiniwake wa Ava, Janet Dieter. “Titasamalira agalu opitilira 40, iye anali 'wotayika' wathu woyamba amene tinamulera. Panthawiyo tinalinso ndi Labrador wina wakuda wotchedwa Roscoe, yemwe ankakonda kusiya ana agalu olera, koma anakondana ndi Ava nthawi yomweyo ndipo tinkadziwa kuti ayenera kukhalabe.”
Janet ndi mwamuna wake Ken nthawi zonse amapita ndi agalu awo kusukulu yophunzitsa ana, ndipo Ava nayenso ndi wosiyana. Komabe, pamenepo ndi pomwe awiriwa anayamba kuzindikira china chake chosiyana ndi iye.
"Nkhani inayamba kubuka yokhudza momwe mungaletsere galu wanu kuti asakulumphireni, ndipo tinazindikira kuti Ava sangatilumphire," adatero Janet. "Tinamutengera kwa dokotala wa ziweto ndipo adamujambula x-ray yomwe idawonetsa kuti chiuno cha Ava chinali chitasokonekera."
A Dieters adatumizidwa kwa dokotala wodziwa bwino ntchito yosintha chiuno chonse yemwe adachita opaleshoni yosintha chiuno chonse cha Ava mu 2013 ndi 2014.
“Kulimba mtima kwake n’kodabwitsa,” anatero Janet. “Anatuluka m’chipatala ngati kuti palibe chomwe chachitika.”
Kuyambira nthawi imeneyo, Ava yathandiza ana agalu olera a banjali omwe amadya zakudya zosiyanasiyana kupeza anthu oti azisewera nawo. Pamene banja la Dieter linasamuka kuchoka ku Illinois kupita ku Texas zaka zingapo zapitazo, iye anasintha kwambiri.
“Kwa zaka zambiri, mipira yopangira yawononga pulasitiki yomwe imateteza makoma achitsulo a mafupa opangidwa,” anatero Dr. Brian Sanders, pulofesa wa mafupa a nyama zazing'ono komanso mkulu wa ntchito za mafupa a nyama zazing'ono ku Chipatala Chophunzitsa Zanyama. “Kenako mpira wopangirawo unawononga maziko achitsulocho, zomwe zinapangitsa kuti malo olumikizirana asokonezeke.”
Ngakhale kuti kuwonongeka konse kwa cholumikizira cha m'chiuno n'kosowa mwa agalu, kungachitike posintha cholumikizira chomwe chakhala chikugwiritsidwa ntchito kwa zaka zambiri.
“Pamene Ava anaika chiuno chake choyamba, chivundikiro cha cholumikizira cholowa m'malo sichinapite patsogolo monga momwe chilili panopa,” anatero Sanders. “Ukadaulo wapita patsogolo kwambiri moti vutoli silingachitike kawirikawiri. Mavuto ngati a Ava ndi osowa, koma akachitika, ukadaulo wapamwamba umafunika kuti zinthu ziyende bwino.”
Kuwonjezera pa kusokonekera kwa malo, kuwonongeka kwa makoma achitsulo a m'chiuno cha Ava kunapangitsa kuti tinthu tating'onoting'ono tachitsulo tidziunjikane mozungulira malo olumikizirana mafupa ndi mkati mwa ngalande ya m'chiuno, zomwe zinapanga ma granuloma.
"Granuloma kwenikweni ndi thumba la minofu yofewa yomwe ikuyesera kusunga zidutswa zachitsulo," adatero Sanders. "Ava anali ndi granuloma yayikulu yachitsulo yomwe inkatseka mwayi wopita ku cholumikizira chake cha m'chiuno ndikukhudza ziwalo zake zamkati. Izi zingapangitsenso thupi lake kukana ma implants aliwonse a THR.
"Kuyika kwa chitsulo—njira yowononga yomwe imapangitsa kuti zidutswa zachitsulo zisonkhanirane mu granulomas—kungayambitse kusintha kwa maselo komwe kumapangitsa kuti fupa lozungulira chiuno chatsopano lizisungunuka kapena kusungunuka. Zili ngati kuika thupi mu njira yodzitetezera kuti lidziteteze ku zinthu zakunja," adatero.
Chifukwa cha zovuta za opaleshoni yomwe imafunika kuchotsa granuloma ndikukonza chiuno cha Ava, dokotala wa ziweto wa Diters adalangiza kuti akaone katswiri wa mafupa ku Texas A&M University.
Pofuna kuonetsetsa kuti ntchito yovutayi ikuyenda bwino, Sanders adagwiritsa ntchito njira zamakono zopangira opaleshoni zotsogozedwa ndi CT komanso ukadaulo wosindikiza wa 3D.
“Timagwiritsa ntchito chitsanzo cha makompyuta cha 3D kuti tidziwe kukula ndi malo a zomangira za prosthetic,” akutero Saunders. “Tinasindikiza chithunzi chenicheni cha chiuno cha Ava chomwe chinasochera ndipo tinakonza momwe tingachitire opaleshoni yokonzanso pogwiritsa ntchito chitsanzo cha 3D cha fupa. Ndipotu, tinayeretsa mitundu ya pulasitiki ndi kuigwiritsa ntchito m'chipinda chochitira opaleshoni kuti tithandize pa opaleshoni yokonzanso.”
"Ngati mulibe pulogalamu yanu yosindikizira ya 3D, muyenera kugwiritsa ntchito njira yolipirira ntchito kuti mutumize ma CT scan ku kampani yachitatu. Zingakhale zovuta pankhani ya nthawi yogwira ntchito, ndipo nthawi zambiri mumataya mwayi wochita nawo ntchito yokonzekera," adatero Sanders.
Kukhala ndi chifaniziro cha matako a Ava kunali kothandiza kwambiri poganizira kuti granuloma ya Ava inkapangitsa zinthu kukhala zovuta kwambiri.
"Kuti tipewe kukana kwa THR, timagwiritsa ntchito CT scan ndikugwira ntchito ndi gulu la madokotala opereka opaleshoni ya minofu yofewa kuti tichotse granuloma yachitsulo yambiri m'njira ya m'chiuno momwe tingathere kenako n’kuibwezeretsa kuti ikonzedwenso ndi THR. Kenako tikachita kukonzanso, tikhoza kumaliza opaleshoniyo mbali inayo pochotsa granuloma yotsalayo mbali imodzi," adatero Sanders. "Kugwiritsa ntchito mitundu ya 3D pokonzekera ndikugwira ntchito ndi gulu la minofu yofewa kwakhala zinthu ziwiri zofunika kwambiri kuti tipambane."
Ngakhale opaleshoni yoyamba ya Ava yokonzanso chiuno inayenda bwino, koma vuto lake silinathe. Patatha milungu ingapo kuchokera pamene opaleshoni yoyamba inachitidwa, chotsukira china cha Ava cha THR chinawonongekanso ndi kusokonekera. Anayenera kubwerera ku VMTH kuti akalandire chithandizo chachiwiri cha chiuno.
"Mwamwayi, chiuno chachiwiri sichinawonongeke kwambiri ngati choyamba, ndipo tinali kale ndi chigoba chake cha 3D kuchokera ku opaleshoni yake yaposachedwa, kotero opaleshoni yachiwiri yokonzanso chiuno inali yosavuta kwambiri," adatero Saunders.
“Akuthamangabe kumbuyo kwa nyumba ndi bwalo lathu losewerera,” anatero Janet. “Anadumphanso pamwamba pa sofa.”
“Pamene anayamba kusonyeza zizindikiro zoyamba za kutopa m’chiuno mwake, tinaganiza kuti mwina ndi mapeto ake ndipo tinadabwa,” anatero Ken. “Koma madokotala a ziweto ku Texas A&M adamupatsa moyo watsopano.”
