I-Femoral Neck Antirotation System (FNAS)

Kwa-FNAS, siyakuqonda ukubaluleka kokwenza inzalo ezinqubweni zokuhlinzwa.Yingakho umkhiqizo wethu utholakala emaphaketheni angenalutho, oqinisekisa izinga eliphezulu lokulawula ukutheleleka.Nge-FNAS, ungaba nokuthula kwengqondo ngokwazi ukuthi iziguli zakho zithola ukunakekelwa okukhulu.

Esinye sezici ezibalulekile ze-FNAS i-Integrated Bolt kanye ne-Antirotation Screw system, ehlinzeka ngokuqina okujikelezayo okuvelele nge-engeli yokuhlukana engu-7.5°.Lo mklamo uvumela ukufakwa kokufakelwa ngisho nasezimeni zezintamo ezincane ze-femoral, okwenza kube kulungele iziguli eziningi.

I-FNAS Bolt, nedizayini yayo yesilinda, ihloselwe ukugcina ukuncipha ngesikhathi ifakwa.Lokhu kusho ukuthi uma idivayisi isisendaweni, ungathemba ukuthi ukunciphisa kuzogcinwa kuyo yonke inqubo yokuphulukisa.Ukwengeza, i-Bolt inikeza ukuzinza kwe-angular nge-engeli engaguquki phakathi kwe-Bolt ne-Antirotation Screw, iqinisekisa ukuzinza nokuthembeka okukhulu ekuqhekekeni kwentamo yesifazane.

Esinye isici esivelele se-FNAS ukwakheka kwayo okuguquguqukayo, okuhlanganisa i-Bolt ne-Antirotation Screw ibe uhlelo olulodwa oludidiyelwe.Lo mklamo oyingqayizivele uvumela ukusebenzisana okungenazihibe phakathi kwezingxenye, okuholela ekusebenzeni okuthuthukisiwe nokusebenza.Nge-FNAS, ungathemba ukuthi unikeza iziguli zakho isixazululo esisezingeni eliphezulu.

Sengiphetha, i-Femoral Neck Antirotation System (FNAS) ishintsha umdlalo emkhakheni wokuhlinzwa kwamathambo.Ngezici zayo ezintsha ezifana ne-Integrated Bolt kanye ne-Antirotation Screw system, izinketho zokuvala inzalo, nomklamo oguqukayo, i-FNAS ibeka izinga elisha ekuzinzeni okujikelezayo kokuphuka kwentamo yesifazane.Themba i-FNAS ngemiphumela ehlukile kanye nemiphumela yesiguli ethuthukisiwe.
