I-Labrador Retriever egama lingu-Ava yafumana utyando lwesibini lwe-hip endaweni yotyando ngoncedo lweengcali zezilwanyana zase-Texas A & M University, i-computed tomography (CT)-isicwangciso esikhokelwayo kunye ne-3D yokushicilela iteknoloji.Emva koko buyela ekubalekeni nasekudlaleni nosapho lwakho.
Xa amalungu amabini e-hip Ava efunyenwe njengenjana egugile ngo-2020, oogqirha bezilwanyana base-Texas A&M bawasusa amalungu amadala kwaye bawatshintsha amatsha, besebenzisa isicwangciso esikhokelwa yi-CT, iimodeli zamathambo eziprintiweyo ze-3D kunye noqhaqho oluvavanyiweyo ukuqinisekisa ukuba utyando luhamba kakuhle kwaye alunantlungu. .uya kuphumelela.
Azikho izinja ezininzi ezihamba ngotyando olupheleleyo lwe-hip replacement (THR) ebomini bazo, kodwa i-Ava ibisoloko ikhethekile.
"U-Ava weza kuthi xa wayemalunga neenyanga ezi-6 ubudala kwaye singabazali bezinja ezihlala e-Illinois," kusho umnini ka-Ava, uJanet Dieter.“Emva kokunyamekela izinja ezingaphezu kwama-40, waba ngumntu wokuqala ‘osisilahleko’ esathi ekugqibeleni samkhulisa.Sasinenye iLabrador emnyama egama linguRoscoe ngelo xesha, owayethanda ukuzikhwebula kubantwana abakhuliswa ngabanye abantwana, kodwa wathandana noAva ngoko nangoko kwaye sasisazi ukuba kuya kufuneka ahlale.
UJanet nomyeni wakhe uKen bahlala bethatha izinja zabo ukuya nabo kwisikolo sokuthobela, kwaye uAva akanjalo.Noko ke, kulapho esi sibini saqalisa ukuphawula into eyahlukileyo ngaye.
"Isihloko siye savela malunga nendlela yokunqanda inja yakho ekuxhumeni kuwe, kwaye saqonda ukuba u-Ava akanakuze atsibele kuthi," kusho uJanet."Samsa kugqirha wezilwanyana wasekhaya kwaye benza i-x-reyi ebonisa ukuba isinqe sika-Ava sasiphumile."
I-Dieters yathunyelwa kugqirha onamava otshintshileyo we-hip owenze ukutshintshwa kwe-hip epheleleyo ye-Ava kwi-2013 kunye ne-2014.
“Ukomelela kwakhe kuyamangalisa,” watsho uJanet."Uphume esibhedlele ngathi akukho nto yenzekileyo."
Ukusukela ngoko, u-Ava uye wanceda iinjana zesibini ezikhulisayo ukuba zifumane abantu abaza kudlala nazo.Xa usapho lukaDieter lusuka e-Illinois lusiya eTexas kwiminyaka eliqela eyadlulayo, waluthatha olo tshintsho.
"Kwiminyaka emininzi, iibhola ezenziweyo zigugile i-liner yeplastiki ekhusela iindonga zetsimbi zamalungu okufakelwa," kusho uDkt Brian Sanders, unjingalwazi wezilwanyana ezincinci kunye nomlawuli weenkonzo zezilwanyana ezincinci kwiSibhedlele Sokufundisa Sezilwanyana."Ibhola eyenziweyo emva koko yasinxibisa isiseko sentsimbi, yabangela ukushukuma ngokupheleleyo."
Nangona ukugqoka okupheleleyo kunye nokukrazula komdibaniso we-hip kunqabile kwizinja, kunokwenzeka xa kufakwa indawo yokudibanisa esetyenziswe iminyaka emininzi.
“Xa u-Ava wayefakelwe isinqe sakhe sokuqala, i-padding kwindawo edibeneyo ayizange iphuhliswe njengoko injalo ngoku,” utshilo uSanders.“Itekhnoloji ihambele phambili kangangokuba le ngxaki ingenakwenzeka kangako.Iingxaki ezinjengee-Ava zinqabile, kodwa xa zisenzeka, itekhnoloji ephucukileyo iyafuneka ukuze kufikelelwe kwisiphumo esiyimpumelelo. ”
Ukongeza kwi-dislocation, ukukhukuliseka kweendonga zetsimbi ze-Ava's hip kuye kwabangela ukuba iincinci ezincinci zetsimbi ziqokelele ngeenxa zonke kunye nangaphakathi komsele we-pelvic, zenza i-granulomas.
"Igranuloma ngokusisiseko yibhegi yezicubu ezithambileyo ezizama ukubamba amaqhekeza esinyithi," utshilo uSanders.“U-Ava wayenegranuloma enkulu yesinyithi eyayithintela ukungena kwilungu lesinqe sakhe kwaye ichaphazela amalungu akhe angaphakathi.Oku kunokubangela ukuba umzimba wakhe ukwale naziphi na izifakelo zokufakelwa ezenziwe ngokwenziwa ze-THR.
"I-Metal deposition-inkqubo ephazamisayo eyenza ukuba iziqwenga zetsimbi ziqokelele kwi-granulomas-kunokubangela utshintsho lweselula olubangela ukuba ithambo elijikeleze i-hip entsha lihlaziye okanye linyibilike.Kufana nokubeka umzimba kwimo yokuzikhusela ukuze uzikhusele kwizinto zangaphandle,” utshilo.
Ngenxa yobunzima botyando olufunekayo ukususa i-granuloma kunye nokulungisa i-hip ye-Ava, ugqirha wezilwanyana wasekhaya wase-Diters uncome ukuba babone ingcali yamathambo kwiYunivesithi yase-Texas A & M.
Ukuqinisekisa ukuphumelela komsebenzi onzima, uSanders wasebenzisa isicwangciso sotyando esikhokelwa yi-CT kunye ne-3D yokushicilela iteknoloji.
“Sisebenzisa imodeli yekhompyuter ye-3D ukujonga ubungakanani kunye nokubekwa kwezinto ezifakelweyo zokufakelwa,” utshilo uSaunders.“Siprinte umfanekiso wenyonga ka-Ava ephumileyo saza sacwangcisa kanye indlela yokwenza utyando oluhlaziyiweyo kusetyenziswa imodeli ye3D yethambo.Ngapha koko, sazicocisa iimodeli zeplastiki saza sazisebenzisa kwigumbi lokutyanda ukuze sincede kuqhaqho lokwakha kwakhona.”
“Ukuba awunayo eyakho inkqubo yoshicilelo ye-3D, kuya kufuneka usebenzise inkqubo yokuhlawulela inkonzo ukuthumela ii-CT scans kwinkampani yangaphandle.Kunokuba nzima ngokwexesha lokutshintsha, kwaye uhlala uphulukana namandla okuthatha inxaxheba kwinkqubo yokucwangcisa, ”utshilo uSanders.
Ukuba ne-replica ye-Ava's butt kwaba luncedo ngakumbi xa ucinga ukuba igranuloma ka-Ava yayisenza izinto zibe nzima ngakumbi.
"Ukunqanda ukwaliwa kwe-THR, sisebenzisa i-CT scan kwaye sisebenze neqela loogqirha botyando lwezicubu ezithambileyo ukususa uninzi lwe-granuloma yesinyithi kumjelo we-pelvic ngokusemandleni kwaye emva koko sibuyele kuhlaziyo lwe-THR.Ke xa sisenza uhlaziyo, sinokulugqiba utyando kwelinye icala ngokususa igranuloma eseleyo kwelinye icala, ”utshilo uSanders."Ukusebenzisa iimodeli ze-3D zokucwangcisa kunye nokusebenza kunye neqela lezicubu ezithambileyo zibe zizinto ezimbini ezibalulekileyo kwimpumelelo yethu."
Ngelixa utyando lokuqala luka-Ava lokwakhiwa ngokutsha kwenyonga luhambe kakuhle, ingxaki yakhe ayikapheli.Kwiiveki ezimbalwa emva kotyando lokuqala, enye iphedi ye-THR ka-Ava nayo yaguga kwaye yagxothwa.Kwafuneka abuyele kwi-VMTH kuhlaziyo lwe-hip yesibini.
"Ngethamsanqa, i-hip yesibini ayizange yonakaliswe kakhulu njengeyokuqala, kwaye sasisele sinemodeli ye-3D ye-skeleton yakhe ukusuka kwi-skeleton yakhe yakutshanje, ngoko ke utyando lwesibini lwe-hip lwalulula ngakumbi," kusho uSaunders.
“Usatsiba-tsiba emva kweyadi nakwibala lethu lokudlala,” watsho uJanet."Wade watsibela phezu kwesofa."
"Xa eqala ukubonakalisa iimpawu zokuqala zokugqoka ezinqeni zakhe, sasicinga ukuba ingaba sekupheleni kwaye sothuka," kusho uKen.Kodwa oogqirha bezilwanyana eTexas A&M bamnike ubomi obutsha.
Iingcali zonyango lwezilwanyana kwiYunivesithi yaseTexas A&M zithi ukubonelela "indawo ekhuselekileyo" kwiikati ngundoqo kwiintshayelelo eziyimpumelelo.
Oochwephesha bezilwanyana bathanda ukudinwa kakhulu kwaye basengozini yokufa ngokuphindwe kahlanu ngenxa yokuzibulala kunoluntu ngokubanzi.
Izazinzulu ziya kusebenza ukuqonda ukuba intsholongwane ebangela i-COVID-19 isasazeka njani phakathi kwamaxhama kunye nokuba iyichaphazela njani impilo yabo iyonke.
