Kune varwere vava kuda kuisirwa chiuno kana kuti vari kufunga nezvekuisirwa chiuno mune ramangwana, pane zvisarudzo zvakawanda zvakakosha zvekuita. Sarudzo huru ndeyekusarudza nzvimbo yekutsigira majoini: simbi-pa-simbi, simbi-pa-polyethylene, ceramic-pa-polyethylene, kana ceramic-pa-ceramic. Dzimwe nguva, izvi zvinogona kuva dambudziko!
Kuvhiyiwa kwehudyu zvachose kunogona kushandiswa kutsiva joini yechiuno ine arthritis, uchishandisa jira rekugadzira rejoini kubvisa marwadzo anokonzerwa nekukwesha nzvimbo.
Mapurasitiki ekugadzira akagadzirwa kuti ape varwere kugadzikana kwakanyanya uye kusakara zvakanyanya. Zvigadzirwa zvesimbi nepolyethylene zvechinyakare zvave zvichishandiswa kubvira kuma1960, asi kufambira mberi muhunyanzvi kwakaita kuti zvinhu zveceramic nezvimwe zvinhu zviwedzere kufarirwa.
Zvinhu zvinotsiva majoini ehudyu
Chimwe chezvinetso zvinowanzoitika mushure mekuiswa kwechiuno mushure mekuiswa kwechiuno ndechekusakara kwenhengo dzemuviri dzinobatanidzwa kubva pakushandiswa kwakajairika. Zvichienderana nemamiriro ezvinhu chaiwo emurwere, akadai sezera, saizi, nhanho yekushanda, uye ruzivo rwachiremba wezvekurapa nechinhu chakagadzirwa, chinhu chakagadzirwa nechiuno chinogona kugadzirwa nesimbi, polyethylene (purasitiki), kana ceramic. Semuenzaniso, kana murwere ari munhu anoshanda zvakanyanya kana kuti achiri mudiki uye achida kufamba zvakanyanya mushure mekuvhiyiwa, chiremba wezvemapfupa anogona kukurudzira kuti chigadzirwe chechiuno chinogadzirwa neceramic.
1、Musoro webhora resimbiuye jira repurasitiki (polyethylene).
Mabhora esimbi akajairwa uye mapurasitiki epurasitiki akagadzirwa nekapu zvave zvichishandiswa kubvira kuma1960. Tsvagiridzo yesainzi inoratidza kuti kushandiswa kwemapurasitiki epurasitiki akavandudzwa, anozivikanwa se "highly-linked" polyethylene liners, kunogona kuderedza zvakanyanya kupfeka kwema implants. Nekuda kwekugara kwayo kwenguva refu uye zvimwe zvinhu zvine chekuita nayo, polyethylene yesimbi yave iri chinhu chinosarudzwa nevarapi vemapfupa vezvikamu zvechiuno zvekugadzira kubva pakaitwa kuvhiyiwa kwekutanga kwekutsiva chiuno. Bhora resimbi rakagadzirwa ne cobalt-chromium alloy uye jira racho rakagadzirwa ne polyethylene.
2、Musoro webhora reCeramicuye jira repurasitiki (polyethylene)
Zvidimbu zvesimbi zvakaoma kupfuura simbi uye ndizvo zvinonyanya kukwachurwa. Zvidimbu zvesimbi zvinoshandiswa pakuvhiya majoini zvine nzvimbo dzakaoma, dzisingakwechurwi, dzakapfava zvikuru dzinogona kuderedza zvakanyanya kupera kwe polyethylene friction interfaces. Kupera kwesimbi iyi kwakaderera pane kupera kwesimbi pa polyethylene.
3、 Musoro wesimbi nesimbi yesimbi
Zvishandiso zvesimbi-pane-simbi (cobalt-chromium alloys, dzimwe nguva simbi isina ngura) zvakamboshandiswa kare muna 1955, asi hazvina kubvumidzwa neFDA kuti zvishandiswe muUnited States kusvika muna 1999. Sezvo tekinoroji ichifambira mberi, kupera simba kunoderera zvakanyanya, zvichikonzera kuzvimba kushoma uye kurasikirwa nemapfupa. Mabheya esimbi anowanikwa muhukuru hwakasiyana-siyana (kubva pa28mm kusvika 60mm), pamwe nesarudzo dzakasiyana-siyana dzekureba kwemutsipa. Zvisinei, mishumo yenguva refu mushure mekuvhiyiwa inoratidza kuti simbi, seion inoshanda zvishoma, inounganidza tsvina yesimbi nekuda kwekukwegura kwenguva refu, izvo zvinogona kutungamira mukuputsika kwemapfupa akatenderedza pfupa rejoint prosthesis, zvichizopedzisira zvaita kuti joint prosthesis isununguke uye ishanduke. Kuvhiya kwacho kwakakundikana.
4、Musoro webhora reCeramic uyejira receramic
Mumahudyu aya, mabhora esimbi echinyakare uye mapurasitiki epurasitiki akatsiviwa nemidziyo yesimbi yakasimba, inozivikanwa nekushanda kwayo kusingapfeki zvakanyanya. Zvisinei, kunyange zvazvo iine zvakanakira zvemhando yepamusoro uye kusapfeki zvakanyanya, inewo dambudziko remutengo wakakwira.
Sarudzo yekupedzisira yekuisa chisimbiso ichasarudzwa zvichienderana nehutano hwemurwere uye zvinodawo hunyanzvi hwachiremba wemapfupa, dzidzo, uye hunyanzvi kuti agadzirise chigadzirwa chemugadziri. Saka, zvakakosha kukurukura nachiremba wako wemapfupa usati wavhiyiwa kuti unzwisise rudzi rwechisimbiso chavanoda kushandisa pakuvhiyiwa kwako kwekutsiva chiuno, uye zvikonzero zvekusarudza chisimbiso chaicho.
