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!

Chimwe chezvinetso zvinowanzoitika mushure mekugadziriswa kwechiuno ndechekusakara kwenhengo dzemuviri dzinobatanidzwa nekushandiswa kwakajairika. Zvichienderana nemamiriro ezvinhu chaiwo emurwere, akadai sezera, saizi, nhanho yekushanda, uye ruzivo rwachiremba wezvekuvhiya nechinhu chakagadzirwa, Theorhetopediahip izvinodyarwainogona kugadzirwa nesimbi, polyethylene (purasitiki), kana ceramic. Semuenzaniso, kana murwere ari munhu anoshanda zvakanyanya kana kuti achiri mudiki uye achida kufamba zvakanyanya mushure mekuvhiyiwa, chiremba wemapfupa anogona kukurudzira kuti aisirwe chiuno chake neceramic.
1. Musoro wesimbi nepurasitiki (purasitiki) mukati
Mabhora esimbi akajairwa uye mapurasitiki epurasitiki agara achishandiswa 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.azvechinyakarehip jmafutakubva pakaitwa oparesheni yekutanga yekutsiva chiuno. Bhora resimbi rakagadzirwa necobalt-chromium alloy uye jira racho rakagadzirwa nepolyethylene.
2. Musoro webhora receramic uye jira repurasitiki (repurasitiki)
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 webhora resimbiuye simbi yepurasitiki
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 reCeramicuyejira receramic
Mune izviazvechinyakarehip jmafutassisitimus, 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 yehip jmafutaichidyarwazvichaongororwa 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 rwechigadzirwa chavanoda kushandisa pakuvhiyiwa kwako kwekutsiva chiuno, uye zvikonzero zvekusarudza chigadzirwa chaicho.
Kana uchida kudzidza zvakawanda nezve chiuno chekugadziraruzivo, ndapota inzwa wakasununguka kutaura nesu; timu yedu ichakupa rutsigiro rwehunyanzvi nemhinduro.
