Tibial Tuberosity Iterambere (TTA) Sisitemu: Ubuhanga bugezweho bwo kubaga bwa Canine Cruciate Ligament Gusana
Intangiriro
Ligamenti y'imbere (ACL) ni imwe mu mitsi ikomeretsa cyane mu rugingo rw'inyuma rwa kine, biganisha ku guhungabana hamwe, kubabara, ndetse amaherezo n'indwara ifata ingingo (DJD). Kubaga kubaga akenshi bisabwa kugirango ugarure umutekano kandi wirinde kwangirika kwingingo. Bumwe mu buryo bwa vuba bwo kubaga bwo gusana ACL ni sisitemu ya Tibial Tuberosity Advancement (TTA), imaze kwamamara kubera akamaro kayo mu kunoza imikorere ihuriweho, kugabanya ububabare, no kugabanya ingorane nyuma yo kubagwa. Muri iyi ngingo, tuzacengera cyane muri sisitemu ya TTA, amahame yayo, imikoreshereze, inyungu, n'imbibi.
Anatomy na Physiologiya ya Canine Stifle Ifatanije
Mbere yo gucengera muri sisitemu ya TTA, ni ngombwa gusobanukirwa anatomiya na physiologiya ya kineine ifata ingingo. Igice cya stifle gihwanye ningingo yivi yumuntu kandi igizwe namagufwa ya femur, tibia, na patella. ACL ishinzwe guhuza ingingo mukurinda tibia kunyerera imbere ugereranije nigitsina gore. Mu mbwa, ACL iherereye muri capsule ihuriweho kandi igizwe na fibre ya kolagen ifata amagufwa ya femur na tibia.
Indwara ya ACL Rupture mu mbwa
Guturika kwa ACL mu mbwa birashobora kubaho kubera impamvu zitandukanye, zirimo genetiki, imyaka, umubyibuho ukabije, imyitozo ngororamubiri, n'ihahamuka. Iyo ACL iturika, igufwa rya tibia riranyerera imbere, bigatuma ingingo idahinduka, bikaviramo ububabare, gutwika, amaherezo na DJD. Ubuyobozi bushinzwe kubungabunga ibidukikije, nko kuruhuka, imiti, no kuvura umubiri, birashobora gufasha kugabanya ububabare, ariko ntibikemura ikibazo cyihishe inyuma y’ihungabana. Kubaga kubaga akenshi bisabwa kugirango ugarure umutekano kandi wirinde kwangirika kwingingo.
Amahame ya sisitemu ya TTA
Sisitemu ya TTA nubuhanga bugezweho bwo kubaga kine ya ACL isana igamije kugarura ituze hamwe muguhindura inguni yibibaya. Ikibaya cya tibial nubuso bwo hejuru bwigufwa rya tibia rivuga hamwe nigufwa ryigitsina gore kugirango ribe ingingo ifatanye. Mu mbwa zacitse ACL, ikibaya cya tibial kiramanuka epfo, bituma igufwa rya tibia ryinyerera imbere ugereranije nigufwa ryigitsina gore. Sisitemu ya TTA ikubiyemo guca tibial tuberosity, igufwa ryamagufwa riri munsi yikivi, no kuyiteza imbere kugirango yongere inguni yibibaya. Iterambere rihagaze neza ukoresheje akazu ka titanium na screw, biteza imbere gukiza amagufwa no guhuza.
Ibyiza bya sisitemu ya TTA
Sisitemu ya TTA itanga inyungu nyinshi kurenza tekinike gakondo yo gusana ACL, nka tibial plateau iringaniza osteotomy (TPLO) hamwe no gusana hanze. Ubwa mbere, sisitemu ya TTA irumvikana neza muburyo bwa biomehanike, kuko ihindura inguni yibibaya bya tibial kugirango irinde gutera imbere, niyo mpamvu nyamukuru itera ACL. Icya kabiri, sisitemu ya TTA irinda ACL kavukire, igabanya ibyago byingaruka nko kwandura, kunanirwa kwangirika, no gutsindwa. Icya gatatu, sisitemu ya TTA yemerera hakiri kare kubyara ibiro no kubyara, bitezimbere imikorere ihuriweho kandi bigabanya igihe cyo gukira. Icya kane, sisitemu ya TTA ibereye imbwa zingero zose nubwoko bwose, kuko ishobora gutegurwa kubyo umuntu akeneye.
Imipaka ya sisitemu ya TTA
Kimwe na tekinike iyo ari yo yose yo kubaga, sisitemu ya TTA ifite aho igarukira kandi ishobora kuba ingorane. Ingorane zikunze kugaragara ni kunanirwa guterwa, bishobora kubaho kubera guhangayika, kwandura, cyangwa gukira amagufwa. Kunanirwa kwimurwa birashobora kugutera guhungabana, kubabara, no gukenera kubagwa.
Izindi ngaruka zishobora guterwa na sisitemu ya TTA zirimo kuvunika tibial crest kuvunika, patellar tendonitis, hamwe na effusion hamwe. Byongeye kandi, sisitemu ya TTA nubuhanga bugoye bwo kubaga busaba amahugurwa ninzobere kabuhariwe, bishobora kugabanya kuboneka kwayo mubuvuzi bwamatungo. Byongeye kandi, sisitemu ya TTA ihenze kuruta ubundi buryo bwo gusana ACL, bushobora kuba budashoboka kuri banyiri amatungo.
Abakandida kuri Sisitemu ya TTA
Sisitemu ya TTA ibereye imbwa zifite ACL iturika hamwe no guhungabana hamwe, hamwe nabafite amarira ya menici hamwe na DJD. Umukandida mwiza muri sisitemu ya TTA nimbwa ifite uburemere bwumubiri burenze kg 15, kuko imbwa nto zishobora kuba zidafite amagufwa ahagije yo gushyigikira akazu ka titanium. Byongeye kandi, sisitemu ya TTA ntabwo isabwa imbwa zifite uburambe bukabije bwa patellar, kwangirika gukabije kwa cranial cruciate ligament (CCL), cyangwa kwidagadura hagati.
Isuzuma mbere yo gutangira no gutegura
Mbere yo gukora sisitemu ya TTA, imbwa igomba kwisuzumisha neza mbere yo gutangira, harimo isuzuma ryuzuye ryumubiri, amashusho ya radiografiya, hamwe na laboratoire. Kwerekana amashusho ya radiografiya bigomba kuba bikubiyemo ibitekerezo byombi hamwe no kureba ikibuno kugirango wirinde icyarimwe hip dysplasia cyangwa arthritis. Byongeye kandi, umuganga agomba gutegura yitonze kubagwa, harimo ingano n’umwanya w’akazu ka titanium, ingano yo gutera imbere kwa tibial tuberosity, nubwoko bwa anesteziya no gucunga ububabare.
Ubuhanga bwo kubaga
Sisitemu ya TTA nubuhanga busaba tekinike yo kubaga busaba amahugurwa nubuhanga. Kubaga bikozwe muri anesthesia rusange, kandi imbwa ishyizwe muburyo bwa dorsal. Umuganga ubaga akora ibice hejuru yigituntu kandi agatandukanya imitsi ya patellar kuva mubituntu. Igituntu noneho gicibwa ukoresheje ibiti byabugenewe, hanyuma akazu ka titani gashyirwa hejuru yo gukata. Ikiziriko gifite umutekano ukoresheje imigozi, kandi patellar tendon yongeye kugarukira mubituba. Ihuriro noneho rigenzurwa kugirango rihamye, kandi incike irafunzwe ukoresheje suture cyangwa staples.
Kwitaho nyuma yo kuvurwa no gusubiza mu buzima busanzwe
Nyuma yo kubagwa, imbwa ishyirwa kumiti yububabare na antibiotike, kandi ingingo ikurikiranwa kubyimba, kubabara, cyangwa kwandura. Imbwa yemerewe kwikorera ibiro ku ngingo yibasiwe ako kanya nyuma yo kubagwa, ariko birasabwa gukora ibikorwa bibujijwe mu byumweru bike bya mbere. Imbwa igomba kubikwa kandi ikirinda gusimbuka, kwiruka, cyangwa kuzamuka ingazi. Ubuvuzi bufatika, burimo imyitozo yimyitozo ngororangingo hamwe nimyitozo ngororamubiri, bigomba gutangira muminsi mike nyuma yo kubagwa kugirango imikorere igabanuke kandi ikingire imitsi. Gusura buri gihe hamwe nabaganga babaga birakenewe kugirango bakurikirane inzira yo gukira no kumenya ingorane zishobora kubaho.
Umwanzuro
Sisitemu ya Tibial Tuberosity Advancement (TTA) nubuhanga bugezweho bwo kubaga bwa canine ACL bwo gusana bugamije kugarura ituze hamwe muguhindura inguni yibibaya. Sisitemu ya TTA itanga ibyiza byinshi kubuhanga gakondo bwo gusana ACL, harimo ubuzima bwibinyabuzima, kubungabunga ACL kavukire, hamwe no gusubiza mu buzima busanzwe nyuma yibikorwa. Nyamara, sisitemu ya TTA ifite aho igarukira nibishobora kugorana, kandi bisaba amahugurwa nubuhanga bwihariye. Kubwibyo, icyemezo cyo kunyura muri sisitemu ya TTA kigomba gufatwa nyuma yisuzumabumenyi ryuzuye mbere yo gutangira no kugisha inama umuganga ubaga ubuvuzi bwamatungo wujuje ibyangombwa.
