I-Labrador retriever egama lingu-Ava yenziwe utyando lwesibini lokutshintshwa kwesinqe ngoncedo loogqirha bezilwanyana baseTexas A&M University, ucwangciso olukhokelwa yi-computed tomography (CT) kunye netekhnoloji yokuprinta ye-3D. Emva koko buyela ekubalekeni nasekudlaleni nosapho lwakho.
Xa amalungu amabini esinqe i-Ava eyayiwafumene njengenjana aphela ngo-2020, oogqirha bezilwanyana baseTexas A&M basusa amalungu amadala baza bawatshintsha ngamatsha, besebenzisa ucwangciso olukhokelwa yi-CT, iimodeli zamathambo eziprintiweyo ze-3D kunye notyando oluqhelanisiweyo ukuqinisekisa ukuba utyando luhamba kakuhle kwaye alunantlungu.
Azininzi izinja ezityandwa kane ngokupheleleyo (i-THR) ebomini bazo, kodwa i-Ava ibisoloko ikhethekile.
“U-Ava weza kuthi xa wayeneminyaka emalunga neenyanga ezi-6 ubudala kwaye sasingabantwana bezinja ezikhuliswe ngabanye abantu abahlala e-Illinois,” utshilo umnini we-Ava, uJanet Dieter. “Emva kokunyamekela izinja ezingaphezu kwama-40, waba ngumntu wokuqala ‘ongaphumeleliyo’ esamthatha ekugqibeleni. Sasinenye iLabrador emnyama egama linguRoscoe ngelo xesha, owayethanda ukuzikhwebula kwiinja ezikhuliswe ngabanye abantu, kodwa wathandana no-Ava ngoko nangoko kwaye sasisazi ukuba kuya kufuneka ahlale.”
UJanet nomyeni wakhe uKen bahlala bethatha izinja zabo baye nazo kwisikolo sokuthobela, kwaye uAva akangomntu uhlukileyo. Nangona kunjalo, kulapho esi sibini saqala khona ukubona into eyahlukileyo ngaye.
“Kuvele umxholo malunga nendlela yokuthintela inja yakho ukuba ingakutsibi, saza saqonda ukuba uAva akasayi kuze asitsibe,” utshilo uJanet. “Simse kugqirha wezilwanyana wasekuhlaleni baza benza i-x-ray eyabonisa ukuba isinqe sika-Ava sasiphumile.”
AbakwaDieter bathunyelwe kugqirha onamava wokufaka isinqe ngokupheleleyo owenza utyando lokufaka isinqe ngokupheleleyo kuka-Ava ngo-2013 nango-2014.
“Ukunyamezela kwakhe kuyamangalisa,” utshilo uJanet. “Uphume esibhedlele ngokungathi akukho nto yenzekileyo.”
Ukususela ngoko, u-Ava uye wanceda iinjana ezikhuliswe sibini esitya ukutya ukuba zifumane abantu abanokudlala nabo. Xa usapho lukaDieter lwafudukela eTexas lusuka e-Illinois kwiminyaka eliqela eyadlulayo, wathabatha olu tshintsho ngokukhawuleza.
“Kwiminyaka edlulileyo, iibhola zokwenziwa ziye zaguga iplastiki ekhusela iindonga zesinyithi zamalungu okwenziwa,” utshilo uGqr. Brian Sanders, unjingalwazi we-orthopedics yezilwanyana ezincinci kunye nomlawuli weenkonzo ze-orthopedics zezilwanyana ezincinci kwiSibhedlele soFundiso lweZilwanyana. “Ibhola yokwenziwa yaguga isiseko sesinyithi, yabangela ukuguguleka ngokupheleleyo.”
Nangona ukukrazuka okupheleleyo kwelungu lesinqe kunqabile ezinjeni, kunokwenzeka xa kutshintshwa ilungu elisetyenziswe iminyaka emininzi.
“Xa u-Ava wayefake isinqe sakhe sokuqala, i-padding kwi-joint yokutshintshwa yayingaphuhliswanga njengoko injalo ngoku,” utshilo uSanders. “Itekhnoloji ihambele phambili kangangokuba le ngxaki ayifumaneki lula. Iingxaki ezifana nezika-Ava azixhaphakanga, kodwa xa zisenzeka, kufuneka itekhnoloji ephucukileyo ukuze kufezekiswe isiphumo esiphumelelayo.”
Ukongeza ekuqhekekeni, ukuguguleka kweendonga zesinyithi zesinqe sika-Ava kubangele ukuba amasuntswana amancinci esinyithi aqokelelene ejikeleze ilungu kunye nangaphakathi komjelo we-pelvic, nto leyo eyenza ii-granulomas.
“I-granuloma ngokuyintloko yingxowa yezicubu ezithambileyo ezizama ukubamba iziqwenga zesinyithi,” utshilo uSanders. “U-Ava wayene-granuloma enkulu yesinyithi eyayivala ukufikelela kwilungu lakhe lesinqe kwaye ichaphazela amalungu akhe angaphakathi. Oku kunokubangela ukuba umzimba wakhe ungavumi naziphi na izinto zokufakelwa ze-THR.
“Ukufakwa kwesinyithi—inkqubo ekhukulisayo ebangela ukuba iziqwenga zesinyithi ziqokeleleke kwi-granulomas—kunokubangela utshintsho lweeseli olubangela ukuba ithambo elijikeleze isinqe esitsha liphinde linyibilike okanye liphinde linyibilike. Kufana nokubeka umzimba kwindlela yokuzikhusela ukuze uzikhusele kwizinto zangaphandle,” utshilo.
Ngenxa yobunzima botyando olufunekayo ukususa i-granuloma kunye nokulungisa isinqe sika-Ava, ugqirha wezilwanyana wasekuhlaleni kaDiters wacebisa ukuba babone ingcali yamathambo kwiYunivesithi yaseTexas A&M.
Ukuqinisekisa impumelelo yolu tyando lunzima, uSanders usebenzise ucwangciso lotyando oluphambili olukhokelwa yi-CT kunye netekhnoloji yokuprinta ye-3D.
“Sisebenzisa imodeli yekhompyutha ye-3D ukufumanisa ubungakanani kunye nendawo ezifakwe kuyo izinto zokufakelwa,” utshilo uSaunders. “Ngokusisiseko sishicilele umfanekiso ochanekileyo wesinqe sika-Ava esiphumileyo saza sacwangcisa indlela yokwenza utyando lokuhlaziya sisebenzisa imodeli ye-3D yethambo. Enyanisweni, sihlambulule iintsholongwane kwiimodeli zeplastiki saza sazisebenzisa kwigumbi lotyando ukunceda ngotyando lokwakha kwakhona.”
“Ukuba awunayo inkqubo yakho yokuprinta ye-3D, kuya kufuneka usebenzise inkqubo yokuhlawulisa ngenkonzo ukuthumela ii-CT scans kwinkampani yangaphandle. Kunokuba nzima malunga nexesha lokutshintsha, kwaye uhlala ulahlekelwa kukwazi ukuthatha inxaxheba kwinkqubo yokucwangcisa,” utshilo uSanders.
Ukuba nomfanekiso wempundu ka-Ava kwakunceda kakhulu xa ucinga ukuba i-granuloma ka-Ava yayisenza izinto zibe nzima nangakumbi.
“Ukuze siphephe ukwaliwa kwe-THR, sisebenzisa i-CT scan size sisebenze neqela loogqirha abatyanda izicubu ezithambileyo ukususa i-granuloma yesinyithi kangangoko kunokwenzeka kumjelo we-pelvic size sibuyele kwi-THR revision. Emva koko xa senza uhlaziyo, singagqiba utyando kwelinye icala ngokususa i-granuloma eseleyo kwelinye icala,” utshilo uSanders. “Ukusebenzisa iimodeli ze-3D zokucwangcisa nokusebenza neqela lezicubu ezithambileyo kube zizinto ezimbini ezibalulekileyo kwimpumelelo yethu.”
Nangona utyando lokuqala luka-Ava lokulungisa isinqe luhambe kakuhle, ubunzima bakhe abukapheli. Kwiiveki ezimbalwa emva kotyando lokuqala, enye i-THR pad ka-Ava nayo yaguga yaza yaphuma kwindawo yayo. Kwafuneka abuyele kwi-VMTH ukuze aphinde ahlolwe isinqe okwesibini.
“Ngethamsanqa, isinqe sesibini asizange sonakale kakhulu njengesokuqala, kwaye besisele sinayo imodeli ye-3D yamathambo akhe otyando lwakhe lwakutshanje, ngoko ke utyando lwesibini lokuhlaziya isinqe lube lula nangakumbi,” utshilo uSaunders.
“Usabaleka ejikeleza emva kwendlu nakwibala lethu lokudlala,” utshilo uJanet. “Ude watsiba phezu kwesofa.”
“Xa waqala ukubonisa iimpawu zokuqala zokuguguleka esinqeni sakhe, sacinga ukuba kusenokuba kukuphela kwaso kwaye sothuka,” utshilo uKen. “Kodwa oogqirha bezilwanyana eTexas A&M bamnika ubomi obutsha.”
