Kodi prosthesis ya m'chiuno imatenga nthawi yayitali bwanji?

Hip arthroplasty ndi njira yabwino kwambiri yopangira opaleshoni yochizira femoral mutu necrosis, osteoarthritis wa m'chiuno olowa, ndi kupasuka kwa mafupa.wachikazikhosi paukalamba. Hip arthroplasty tsopano ndi njira yokhwima kwambiri yomwe ikuyamba kutchuka pang'onopang'ono ndipo imatha kumalizidwa ngakhale m'zipatala zina zakumidzi. Chifukwa cha kuchuluka kwa odwala m'malo mwa chiuno, odwala nthawi zambiri amada nkhawa kuti prosthesis idzatenga nthawi yayitali bwanji pambuyo pa opaleshoni ya m'chiuno komanso ngati idzakhala moyo wonse. M'malo mwake, nthawi yayitali bwanji m'malo mwa olowa m'chiuno pambuyo pa opaleshoni zimadalira mbali zitatu zazikulu: 1, kusankha kwa zida: pakali pano pali zida zitatu zazikuluzikulu zolumikizira chiuno chopanga: ① mutu wa ceramic + kapu ya ceramic: mtengo wake udzakhala wokwera kwambiri. Ubwino waukulu wa kuphatikiza uku ndikuti ndizovuta kwambiri kuvala. Mu mikangano ya ceramic ndi ceramic, katundu womwewo, kuvala ndi kung'ambika kofanana ndi mawonekedwe achitsulo ndi ocheperako, ndipo tinthu tating'onoting'ono totsalira pamgwirizano chifukwa chakutha ndi kung'ambika ndizochepa kwambiri, kwenikweni sipadzakhalanso kukana kwa thupi kuvala tinthu tating'onoting'ono. Komabe, pankhani ya ntchito yolemetsa kapena yosayenera, pali chiopsezo chochepa kwambiri cha kupasuka kwa ceramic. Palinso odwala ochepa kwambiri omwe amamva phokoso la "creaking" chifukwa cha mikangano ya ceramic panthawi ya ntchito.

②Mutu wachitsulo + kapu ya polyethylene: mbiri yakugwiritsa ntchito ndiyotalikirapo ndipo ndi kuphatikiza kwapamwamba kwambiri. Chitsulo kuti kopitilira muyeso-mkulu polima polyethylene, ambiri samawoneka mu ntchito ali ndi phokoso lachilendo, ndipo sadzakhala wosweka ndi zina zotero. Komabe, poyerekeza ndi ceramic ndi ceramic friction interface, imavala pang'ono pansi pa katundu womwewo nthawi yomweyo. Ndipo ochepa kwambiri odwala tcheru, izo zidzachita ndi kutha zinyalala, kuchititsa kutupa kuzungulira kuvala zinyalala kuchitika poyankha, ndipo pang'onopang'ono ululu kuzungulira prosthesis, prosthesis kumasuka, etc. ③ Metal mutu + zitsulo bushing: zitsulo zitsulo mikangano mawonekedwe (cobalt-chromium aloyi, nthawi zina zosapanga dzimbiri zitsulo wakhala960) Kusagwirizana uku kumagwiritsidwa ntchito. Komabe, mawonekedwe awa amatha kupanga tinthu tating'onoting'ono tating'onoting'ono, tinthu tating'onoting'ono tomwe timayambitsa Macrophact, ndikupanga ma m'magazi achilendo, kuvala zitsulo zopangidwa kungakhalenso m'magazi, zomwe zimayambitsa matendawa mthupi. M'zaka zaposachedwa, mitundu yolumikizirana iyi idathetsedwa. ④ Mutu wa Ceramic kupita ku polyethylene: Mitu ya Ceramic ndi yolimba kuposa chitsulo ndipo ndi implantation yosagwira kwambiri. Ceramic yomwe pakali pano ikugwiritsidwa ntchito popanga maopaleshoni olowa m'malo mwake ili ndi malo olimba, osakanda, komanso osalala kwambiri omwe amatha kuchepetsa kuchuluka kwa mavalidwe a ma polyethylene friction interfaces. Kuthekera kwa kuvala kwa implant iyi ndi yocheperako poyerekeza ndi chitsulo kupita ku polyethylene, mwa kuyankhula kwina, ceramic kupita ku polyethylene ndizovuta kuvala kuposa chitsulo kupita ku polyethylene! Chifukwa chake, cholumikizira chabwino kwambiri cha m'chiuno, mwazinthu zakuthupi, ndi cholumikizira cha ceramic-to-ceramic. Chifukwa cha moyo wautali wautumiki wa mgwirizanowu ndikuti kuchuluka kwa mavalidwe kumachepetsedwa ndi makumi khumi mpaka nthawi zambiri poyerekeza ndi ziwalo zam'mbuyomu, kukulitsa kwambiri nthawi yogwiritsira ntchito pamodzi, ndipo tinthu tating'onoting'ono timakhala ndi mchere wogwirizana ndi anthu omwe samayambitsa osteolysis ndi osteoporosis kuzungulira prosthesis, yomwe ili yoyenera kwa odwala achinyamata omwe ali ndi ntchito zambiri. 2. Kuyika kolondola kwa chiuno cha mchiuno: kupyolera mwa kuyika kolondola kwa prosthesis panthawi ya opaleshoni, acetabulum ndi phesi lachikazi Kukonzekera kolimba kwa prosthesis ndi ngodya yoyenera kumapangitsa kuti prosthesis ikhale yosasunthika komanso yosasunthika, motero osayambitsa kumasulidwa kwa prosthesis.

Kutetezedwa kwa olowa awo a m'chiuno: kuchepetsa kulemera, ntchito zolemetsa (monga kukwera ndi kulemera kwa nthawi yaitali, etc.) kuti muchepetse kuwonongeka kwa prosthesis. Kuonjezera apo, pewani kuvulala, chifukwa kupwetekedwa mtima kungayambitse fractures kuzungulira chiuno cha prosthesis, zomwe zingayambitse kumasulidwa kwa prosthesis.

Choncho, ma prostheses m'chiuno opangidwa ndi zinthu zochepa abrasive, yeniyeni makhazikitsidwe amgwirizano wa chiunondipo chitetezo chofunikira cha mgwirizano wa chiuno chingapangitse kuti prosthesis ikhale yaitali, ngakhale kwa moyo wonse.
