Hip arthroplasty inzira iri nani yekuvhiya yekurapa femoral head necrosis, osteoarthritis yejoint rehudyu, uye kutyoka kwechiuno.zvechikadzimutsipa pakukwegura. Hip arthroplasty ikozvino inzira yakakura iyo iri kuwana mukurumbira zvishoma nezvishoma uye inogona kupedzwa kunyange mune zvimwe zvipatara zvekumaruwa. Nekuwedzera kwenhamba yevarwere vanotsiva hudyu, varwere vanowanzonetseka pamusoro penguva yakareba sei iyo prosthesis ichagara mushure mekuvhiyiwa kwehudyu uye kana ichagara hupenyu hwose. Muchokwadi, inguva yakareba sei iyo hudyu yekubatanidza kutsiva inogona kushandiswa mushure mekuvhiyiwa kunoenderana nezvinhu zvitatu zvakakosha: 1, kusarudzwa kwezvinhu: parizvino kune matatu makuru emidziyo yekugadzira hudyu majoini: ① ceramic musoro + ceramic mukombe: mutengo uchave wakakwira. Kubatsira kukuru kwemusanganiswa uyu ndekwekuti yakanyanya kupfeka. Muceramic uye ceramic friction, mutoro mumwechete, kupfeka uye kubvarura hukama nesimbi interface idiki, uye twudiki twunosiiwa mugomba rekubatana nekuda kwekupfeka uye kubvaruka zvakare diki zvakanyanya, zvakanyanya hapazove nekuramba muviri kwekupfeka zvimedu. Zvisinei, munyaya yebasa rakaoma kana chimiro chisina kukodzera, kune ngozi shoma shoma yekuputika kwekeramic. Kune zvakare vashoma varwere vanonzwa "creaking" ruzha runokonzerwa nekeramic friction panguva yebasa.
②Metal musoro + polyethylene kapu: nhoroondo yekushandisa yakarebesa uye inosanganisa yakasarudzika. Simbi kune yekupedzisira-yakakwira polymer polyethylene, kazhinji isingaonekwe muchiitiko ichi ine abnormal rattle, uye haizove yakatyoka zvichingodaro. Nekudaro, zvichienzaniswa neceramic kune ceramic friction interface, inopfeka zvishoma zvishoma pasi pemutoro wakafanana panguva imwe chete. Uye mune shoma shoma yevarwere vane hanya, ichaita kune kupera pasi marara, zvichiita kuti kuzvimba kwakatenderedza marara kunoitika mukupindura, uye zvishoma nezvishoma kurwadziwa kwakatenderedza prosthesis, prosthesis kusunungura, etc. ③ Metal musoro + metal bushing: simbi kune simbi friction interface (cobalt-chromium alloy, dzimwe nguva stainless steel has960 stainless simbi) Iri kupindirana kwakaiswa160. Nekudaro, iyi interface inogona kuburitsa huwandu hukuru hwesimbi kupfeka zvimedu, zvimedu izvi zvinogona kuve phagocytosed ne macrophages, zvichigadzira kunze kwemuviri kuita, kupfeka inogadzirwa simbi ions inogona zvakare kupinda muropa, zvichikonzera kusagadzikana mumuviri. Mumakore achangopfuura, rudzi urwu rwekubatanidza majoini akaregwa. ④ Ceramic musoro kune polyethylene: Misoro yeCeramic yakaoma kupfuura simbi uye ndiyo inonyanya kudzvanya inomira. Iyo ceramic parizvino inoshandiswa pakuvhiya majoint replacement ine yakaoma, isingakwenye, yakanyanya-smooth surface inogona kuderedza zvakanyanya kupfekedzwa kwepolyethylene friction interfaces. Iyo inogona kupfeka mwero weiyi kuisirwa ishoma pane simbi kune polyethylene, nemamwe mazwi, ceramic kune polyethylene ine theoretically inopfeka inopokana kupfuura simbi kune polyethylene! Naizvozvo, iyo yakanakisa yekugadzira hudyu yekubatanidza, zvakangoita maererano nezvinhu, ndeye ceramic-to-ceramic interface yekubatanidza. Chikonzero chehupenyu hurefu hwebasa remubatanidzwa uyu ndechekuti chiyero chekupfeka chinoderedzwa nemakumi enguva kusvika kumazana enguva zvichienzaniswa nemajoini apfuura, zvakanyanya kuwedzera nguva yekushandiswa kwemajoini, uye zvimedu zvekupfeka ndezvemaminerari anoenderana nevanhu asingakonzere osteolysis uye osteoporosis yakatenderedza prosthesis, iyo inonyanya kukodzera kuvarwere vechidiki vane basa rakakura. 2. Kunyatsoiswa kwehudyu prosthesis: kuburikidza nekuiswa kwakanyatsoiswa kweprosthesis panguva yekuvhiyiwa, acetabulum uye femoral stalk Kugadziriswa kwakasimba kweprosthesis uye kona yakakodzera inoita kuti prosthesis irege kuiswa uye kubviswa, nokudaro kwete kukonzera kusunungurwa kweprosthesis.
Kudzivirirwa kwemubatanidzwa wavo wehudyu: kuderedza uremu, mabasa akasimba (akadai sekukwira uye kurema kwenguva refu, nezvimwewo) kuderedza kupera uye kubvarura kweprosthesis. Mukuwedzera, kudzivirira kukuvadzwa, nokuti kushungurudzika kunogona kutungamirira kune kuputsika kwakapoteredza hip prosthesis, izvo zvinogona kutungamirira kusunungurwa kweprosthesis.
Nokudaro, mapuroteni ehudyu akagadzirwa nezvinhu zvishoma zvinoputika, kunyatsoiswa kweiyohip jointuye kuchengetedzwa kwakakodzera kwekubatana kwehudyu kunogona kuita kuti prosthesis igare kwenguva refu, kunyange kwehupenyu hwose.
