Umthelela wejiyomethri ye-saw blade ekuqalweni kokuqhekeka nokusabalalisa kumahinge e-HTO lateral cortical

I-high tibial osteotomies (HTO) idlala indima ebalulekile ekulungiseni nasekuphulukisweni kwezinqubo ezithile zamathambo. Kodwa-ke, i-hinge ebuthakathaka idala ingozi enkulu yokwehluleka. Lolu cwaningo luhlose ukuphenya ukuthi ingabe i-geometry yonqenqema lokusika lwensingo yesaha ithinta ukuqaliswa kokuqhekeka noma ukusakazeka kuhinge, futhi uma amajiyometri athile onqenqema angayinciphisa le ngozi.

Izimpahla nezindlela:

Imodeli yesici esinqunyelwe yasungulwa kusetshenziswa izakhiwo zamathambo anwebekayo we-isotropic transversely. Kuqhathaniswe amajiyometri amathathu ahlukene okusika (unxande, okumise u-U, nokumise okwe-V). Isaha eliwugqinsi elingu-1.27 mm lenziwe, lashiya ihinji yekholamu evundlile engu-1 cm. Umthwalo usetshenziswe ukuvula i-osteotomy isekhondi elingu-1. Ukulingisa okubili kwenziwa, eyodwa ngaphandle kokuqaliswa kokuqhekeka kanti enye ino-15° okhuphukayo owehlela phezulu, ukuze kuhlolwe ukugxiliswa kwengcindezi yendawo nokubala izinga lokukhululwa kwamandla ehinji.

Imiphumela:

Ekulingiseni ngaphandle kokuqaliswa kokuqhekeka, ijiyomethri yesaha engunxande ibonise ukugxila kwengcindezi yendawo okuphansi kakhulu. Kodwa-ke, ekulingiseni ngokuqaliswa kokuqhekeka, ijiyomethri emise okwe-U ibonise ukugxila kwengcindezi yendawo okuphansi kakhulu kanye nezinga eliphansi kakhulu lokukhululwa kwamandla. Lokhu kusho ukuthi ijiyomethri emise okuka-U mancane amathuba okuthi iqalise futhi isakaze imifantu kumahinji ekhohlo eliseceleni.

Ingxoxo/

Nakuba lolu cwaningo lusebenzisa ukumodela kwekhompiyutha futhi lunemikhawulo yalo, luphakamisa ukuthi i-geometry enqenqemeni emise okwe-U iphumelela kakhulu ekunciphiseni ubungozi bokuqalwa kokuqhekeka noma ukusabalalisa ngenxa yezinga layo eliphansi lokukhishwa kwamandla. Lokhu okutholakele kusekela i-hypothesis yethu yokuqala futhi kugcizelela ukubaluleka kokucabangela i-geometry enqenqemeni ezinqubweni ze-HTO.

Izingxenyekazi zekhompuyutha ze-AOSITE: Igxile Kwikhwalithi kanye Nokwandiswa Kwemakethe Yamazwe Ngamazwe

I-AOSITE Hardware isalokhu izibophezele ekubekeni phambili ukulawulwa kwekhwalithi, ukuthuthukiswa kwesevisi, kanye nokusabela okusheshayo. Njengoba ulayini wethu womkhiqizo uqhubeka nokuthuthuka futhi uthuthuka, sithole ukunakwa kumakhasimende aphesheya. Ukuzinikela kwethu ekukhiqizeni imikhiqizo emihle kakhulu nasekunikezeni isevisi yobungcweti kusenza sihluke embonini.

Ukusebenza kahle kanye Nekhwalithi

Ihinge ye-AOSITE Hardware yaziwa kabanzi ngokusebenza kwayo okuhle kakhulu kanye nokukhiqizwa kwekhwalithi ephezulu. Ithola ukusetshenziswa kogesi, amawashi, amathoyizi, izinto zokwakha, ezezimoto, kanye nomhlobiso osetshenziswa nsuku zonke. Abasebenzi bethu abanamakhono, ubuchwepheshe obuphambili, kanye nohlelo lokuphatha oluhlelekile lunomthelela ekukhuleni kwethu okuzinzile.

Ukuhola Indlela Yokucwaninga Nentuthuko

Izinga lethu elingu-R&D elihamba phambili embonini liwumphumela wocwaningo oluqhubekayo, ukuthuthukiswa kobuchwepheshe, namandla okudala abaklami bethu. Izingxenyekazi zekhompuyutha ze-AOSITE zizidla ngamahinge enziwe ngezinto zekhwalithi, ukwakhiwa okuhle, kanye nezinhlobonhlobo zemiklamo yokudala nosayizi abajwayelekile, okuqinisekisa ulwazi olunethezekile lomsebenzisi.

Izingxenyekazi zekhompuyutha ze-AOSITE: Ithuthukisa futhi Ikhanyisa Imboni Yokukhanyisa

Ngesipiliyoni seminyaka kanye nomugqa ophelele wokukhiqiza, i-AOSITE Hardware iqhubeka ihlola futhi isungula embonini yokukhanyisa. Izimpumelelo zethu zithuthukise ukubaluleka kwebhizinisi lethu futhi kwaqinisa ukuzibophezela kwethu ekwenzeni kahle kakhulu.

Inqubomgomo Yezimbuyiselo Nezimbuyiselo

Uma kwenzeka ukubuyiselwa kwemali kudingekile, amakhasimende anesibopho sezindleko zokubuyisela emuva. Ngemva kokuthola izinto, imali esele izobuyiselwa ngokufanele.

Sengiphetha, lolu cwaningo luqokomisa indima ebalulekile yokusika i-geometry ekuphumeleleni kwe-osteotomies ephezulu ye-tibial. Ngokukhetha umkhawulo wokusika omise okwe-U, odokotela abahlinzayo bamathambo banganciphisa ingozi yokuqalwa kwe-crack noma ukusabalalisa, kube nomthelela emiphumeleni engcono yesiguli kanye nempumelelo yonke yenqubo.

Umphumela wejiyomethri ye-saw blade ekuqalisweni kokuqhekeka nokusabalalisa kumahinge e-HTO lateral cortical kuyisici esibalulekile okufanele icatshangelwe lapho kwenziwa izinqubo zamathambo. Qhubeka ufunde ukuze ufunde kabanzi mayelana nokuthi imiklamo ye-saw blade ehlukene ingaba nomthelela kanjani ubuqotho bethambo ngesikhathi sokuhlinzwa.
