Thaum nws los txog rau kev phais hloov lub duav, qhovlub taub hau ntawm tus ncej puabntawm lubkev kho lub duav prosthesisyog ib qho ntawm cov khoom tseem ceeb tshaj plaws. Nws ua lub luag haujlwm tseem ceeb hauv kev rov qab txav mus los thiab txo qhov mob rau cov neeg mob uas muaj cov kab mob ntawm lub duav xws li osteoarthritis lossis avascular necrosis ntawm lub taub hau femoral.
Muaj ntau hom pob txha cuav rau koj xaiv, txhua hom tsim los kom ua tau raws li tus neeg mob xav tau thiab xav txog lub cev.Cov ntaub ntawv feem ntau yog hlau, ceramic thiab polyethylene.
Lub taub hau hlauFeem ntau yog ua los ntawm cov hlau cobalt-chromium lossis titanium thiab paub txog lawv qhov ruaj khov thiab lub zog. Lawv feem ntau yog siv rau cov neeg mob hluas dua, uas xav tau kev daws teeb meem zoo uas tuaj yeem tiv taus cov dej num ntau dua.
Cov taub hau ceramic femoral, ntawm qhov tod tes, lawv nyiam rau lawv qhov kev hnav qisthiab biocompatibility. Lawv tsis tshua muaj feem ua rau muaj kev tsis haum tshuaj, ua rau lawv yog qhov kev xaiv zoo tshaj plaws rau cov neeg mob uas muaj kev rhiab heev rau hlau. Ntxiv mus, cov taub hau ceramic femoral muab qhov chaw sib koom ua ke du dua, txo kev sib txhuam thiab kev hnav.
Cov taub hau ntawm cov pob txha caj qaum uas yog polyethylenefeem ntau siv ua ke nrog cov khoom siv hlau lossis cov khoom siv ceramic. Lawv tau tsim los muab kev nplij siab thiab feem ntau pheej yig dua. Txawm li cas los xij, piv rau cov khoom siv hlau lossis cov khoom siv ceramic, lawv yuav hnav sai dua, ua rau lawv tsis haum rau cov neeg mob hluas thiab cov neeg mob uas nquag ua haujlwm ntau dua.
Hauv kev xaus, qhov kev xaiv ntawmlub duavpob qij txhalub taub hau prosthesisyog qhov tseem ceeb rau kev ua tiav ntawm kev phais hloov lub duav. Kev nkag siab txog ntau hom taub hau ntawm cov pob txha femoral—hlau, ceramic, polyethylene, thiab hybrid—tuaj yeem pab cov neeg mob thiab cov kws kho mob txiav txim siab raws li lawv tus kheej xav tau thiab kev ua neej.
