Chipfuyo cheLabrador chinonzi Ava chakavhiyiwazve chiuno chechipiri nerubatsiro rwevanachiremba vemhuka veTexas A&M University, kuronga kwakatungamirirwa necomputer tomography (CT) uye tekinoroji yekudhinda ye3D. Wobva wadzokera kumhanya nekutamba nemhuri yako.
Majoini maviri ehudyu aAva akawanikwa achiri kambwanana paakapera muna 2020, vanachiremba vemhuka vekuTexas A&M vakabvisa majoini ekare ndokuatsiva nemamwe matsva, vachishandisa CT-guided planning, 3D printed bone models uye kuvhiyiwa kwakaitwa kuti vave nechokwadi chekuti kuvhiyiwa kwacho kwafamba zvakanaka uye pasina kurwadziwa.
Imbwa hadzina dzakawanda dzinovhiyiwa kana kuti kuvhiyiwa kweTHR (total hip replacement (THR)) muhupenyu hwadzo, asi Ava yagara iri nyanzvi.
“Ava akauya kwatiri aine mwedzi mitanhatu yekuberekwa uye taiva vabereki vembwa dzinochengetwa nevanhu vaigara muIllinois,” akadaro muridzi weAva, Janet Dieter. “Mushure mekutarisira imbwa dzinopfuura makumi mana, ndiye akatanga ‘kurasikirwa’ nesu takazotora. Takavawo neimwe Labrador nhema yainzi Roscoe panguva iyoyo, yaiwanzoda imbwa dzinochengetwa nevanhu vayo, asi yakadanana naAva nekukurumidza uye taiziva kuti yaizofanira kugara.”
Janet nemurume wake Ken vanogara vachienda nembwa dzavo kuchikoro chekuteerera, uye Ava haasi mumwe chete. Zvisinei, ndipo pavakatanga kuona chimwe chinhu chakasiyana nezvake.
"Nyaya yakataurwa pamusoro pekuti ungadzivisa sei imbwa yako kuti isakusvetukira, uye takaona kuti Ava aisazombotisvetukira," akadaro Janet. "Takamuendesa kuna chiremba wemhuka wemunharaunda uye vakatorwa x-ray yakaratidza kuti chiuno chaAva chakanga chatobuda panzvimbo."
VanaDieter vakaendeswa kuna chiremba ane ruzivo rwekutsiva chiuno chose uyo akaita Ava's total hudyu replacement muna 2013 na2014.
"Kutsungirira kwake kunoshamisa," akadaro Janet. "Akabuda muchipatara sekunge hapana chakaitika."
Kubva ipapo, Ava ave achibatsira imbwa dzevana vanorera dzevaviri ava kuti vawane vanhu vekutamba navo. Mhuri yaDieter payakatama kubva kuIllinois kuenda kuTexas makore akati wandei apfuura, akabvuma kuchinja uku nekukurumidza.
"Mumakore apfuura, mabhora ekugadzira akabvisa jira repurasitiki rinodzivirira madziro esimbi emajoini ekugadzira," akadaro Dr. Brian Sanders, purofesa wezvemapfupa emhuka diki uye director wemabasa emapfupa emhuka diki paVeterinary Teaching Hospital. "Bhora rekugadzira rakazobvisa hwaro hwesimbi, zvichikonzera kutsemuka zvachose."
Kunyangwe kupera kwechiuno chehudyu kusingawanzoitiki mumbwa, zvinogona kuitika kana imbwa ikatsiva chepfu chave chichishandiswa kwemakore mazhinji.
“Ava paakaisa chiuno chake chekutanga, jira rekugadzirisa chiuno rakanga risati ragadzirwa sezvariri pari zvino,” akadaro Sanders. “Tekinoroji yafambira mberi kusvika padanho rekuti dambudziko iri hariwanzoitika. Matambudziko akaita seaAva haawanzoitiki, asi kana akaitika, tekinoroji yepamusoro inodiwa kuti uwane mhedzisiro inobudirira.”
Pamusoro pekuputsika kwenzvimbo, kuputsika kwemadziro esimbi ehudyu yaAva kwakaita kuti zvidimbu zvidiki zvesimbi zviungane zvakatenderedza joini uye mukati memugero wechiuno, zvichigadzira ma granulomas.
"Granuloma chaizvoizvo ibhegi rine nyama yakapfava iri kuedza kubata zvidimbu zvesimbi," akadaro Sanders. "Ava aive negranuloma hombe yesimbi yaivhara kupinda kwejoini rake rechiuno uye ichikanganisa nhengo dzake dzemukati. Izvi zvinogonawo kukonzera kuti muviri wake urambe chero zvipi zvadzo zveTHR prosthetic implants.
"Kuiswa kwesimbi—maitiro anokura anoita kuti zvidimbu zvesimbi zviungane mumagranulomas—kunogona kukonzera shanduko dzemasero dzinoita kuti pfupa rakatenderedza chiuno chitsva rinyungudike kana kunyungudika. Zvakafanana nekuisa muviri muchimiro chekudzivirira kuti uzvidzivirire kubva kuzvinhu zvekunze," akadaro.
Nekuda kwekuoma kwekuvhiyiwa kwaidiwa kubvisa granuloma nekugadzirisa chiuno chaAva, chiremba wemhuka weDiters wemunharaunda akavakurudzira kuti vaone nyanzvi yemapfupa paTexas A&M University.
Kuti ave nechokwadi chekubudirira kwekushanda kwakaomarara, Sanders akashandisa hurongwa hwekuvhiya hwepamusoro hunotungamirirwa neCT uye tekinoroji yekudhinda ye3D.
"Tinoshandisa 3D computer modeling kuti tione saizi uye nzvimbo yeprosthetic implants," anodaro Saunders. "Takadhinda kopi chaiyo yehudyu yaAva yakatyoka uye takaronga chaizvo maitiro ekuvhiya kwekudzokorora tichishandisa 3D model yepfupa. Kutaura zvazviri, takachenesa mapurasitiki emhando iyi ndokuashandisa muimba yekuvhiya kuti tibatsire nekuvhiya kwekuvakazve."
"Kana usina purogiramu yako yekudhinda ye3D, uchafanira kushandisa nzira yekubhadhara kuti utumire CT scans kukambani yechitatu. Zvinogona kuoma kana tichitarisa nguva yekushanda, uye unowanzo rasikirwa nekukwanisa kutora chikamu mukuronga," akadaro Sanders.
Kuva nemufananidzo wematako aAva kwaibatsira zvikuru tichifunga kuti granuloma yaAva yaiita kuti zvinhu zviome zvakanyanya.
"Kuti tidzivise kurambwa kweTHR, tinoshandisa CT scan uye tinoshanda nechikwata chevanachiremba vezvipfuyo zvakapfava kuti tibvise granuloma yesimbi yakawanda kubva muhudyu hwechiuno tobva tadzoka kuzogadziriswazve kweTHR. Zvadaro patinoita revision, tinogona kupedzisa kuvhiya kune rimwe divi nekubvisa granuloma yasara kune rimwe divi," akadaro Sanders. "Kushandisa mamodheru e3D pakuronga nekushanda nechikwata chezvipfuyo zvakapfava kwave kuri zvinhu zviviri zvakakosha mukubudirira kwedu."
Kunyange hazvo kuvhiyiwa kwekutanga kwekugadzirisa chiuno kwaAva kwakafamba zvakanaka, dambudziko rake harisati rapera. Mavhiki mashoma mushure mekuvhiyiwa kwekutanga, imwe THR pad yaAva yakasakarawo ikatyoka. Aifanira kudzokera kuVMTH kuti anoongororwa chiuno kechipiri.
"Nerombo rakanaka, chiuno chechipiri hachina kukuvara zvakanyanya sechekutanga, uye tatova ne3D model yemapfupa ake kubva pakuvhiyiwa kwake kuchangobva kuitwa, saka kuvhiyiwa kwechipiri kwekugadzirisa chiuno kwaive nyore," akadaro Saunders.
"Achiri kumhanya-mhanya achitenderera seri kwemba yedu yekutambira," akadaro Janet. "Akatosvetuka pamusoro pesofa."
"Paakatanga kuratidza zviratidzo zvekuneta muchiuno chake, takafunga kuti kwaizova kuguma uye takashamisika," akadaro Ken. "Asi vanachiremba vemhuka vekuTexas A&M vakamupa hupenyu hutsva."
