He pai ake te pokanga o te hope arthroplasty mō te rongoā i te nekrosis o te pane femur, te osteoarthritis o te hononga hope, me ngā whati o tefemurte kaki i te kaumātuatanga. He tikanga kua pakeke ake te pokanga hope, e piki haere ana te rongonui, ā, ka taea te whakaoti i roto i ētahi hōhipera tuawhenua. I te pikinga ake o te maha o ngā tūroro whakakapinga hope, he maha ngā wā ka āwangawanga ngā tūroro mō te roa o te ora o te prosthesis i muri i te pokanga whakakapinga hope, me te roa rānei o tōna oranga. Inaa, ko te roa o te whakamahinga o te whakakapinga hononga hope i muri i te pokanga e whakawhirinaki ana ki ngā āhuatanga matua e toru: 1, te whiriwhiri rauemi: i tēnei wā e toru ngā rauemi matua mō ngā hononga hope horihori: ① pane uku + kapu uku: ka nui te utu. Ko te painga matua o tēnei huinga ko te ātete ki te kakahu. I roto i te waku uku me te uku, he iti ake te kawenga, te kakahu me te haehae e pā ana ki te atanga whakarewa, ā, he tino iti hoki ngā matūriki iti e toe ana i roto i te kōhao hononga nā te kakahu me te haehae, ko te tikanga kāore he tauhohenga whakakore tinana ki ngā matūriki kakahu. Heoi, i roto i te take o te mahi uaua, te tū tika rānei, he iti rawa te mōrearea o te pakaru uku. He iti noa iho hoki ngā tūroro e pāngia ana e te tangi "keri" i puta mai i te waku uku i te wā mahi.
②Upoko whakarewa + kapu polyethylene: he roa ake te hītori tono, ā, he huinga tawhito ake. Ko te polyethylene polymer whakarewa ki te tino teitei, kāore e puta i roto i te mahi he haruru rerekē, ā, kāore e pakaru me ētahi atu. Heoi, ki te whakatauritea ki te atanga waku uku ki te uku, he iti ake te kakahu i raro i te kawenga kotahi mō te wā kotahi. Ā, i roto i te iti rawa o ngā tūroro tairongo, ka tauhohe ki ngā paru kakahu, ka puta te mumura huri noa i ngā paru kakahu hei whakautu, ā, ka āta mamae haere huri noa i te prosthesis, ka wetekina te prosthesis, me ētahi atu. ③ Upoko whakarewa + pūmau whakarewa: atanga waku whakarewa ki te whakarewa (konumohe cobalt-chromium, i ētahi wā he kowiri tira) Kua whakamahia tēnei atanga waku i ngā tau 1960. Heoi, ka taea e tēnei atanga te whakaputa i te maha o ngā matūriki kakahu whakarewa, ka taea te phagocytose i ēnei matūriki e ngā macrophages, ka puta he tauhohenga tinana ke, ka uru pea ngā katote whakarewa i hangaia e te kakahu ki roto i te toto, ka puta he tauhohenga mate pāwera i roto i te tinana. I ngā tau tata nei, kua mutu te whakamahi i tēnei momo hononga atanga. ④ Te pane uku ki te polyethylene: He mārō ake ngā pane uku i te konganuku, ā, koinei te rauemi whakato tino ātete ki te rakuraku. Ko te uku e whakamahia ana i tēnei wā i roto i ngā pokanga whakakapinga hononga he mata mārō, he ātete ki te rakuraku, he tino maeneene hoki, ka taea te whakaiti i te tere pakaru o ngā atanga waku polyethylene. He iti ake te tere pakaru pea o tēnei whakato i te konganuku ki te polyethylene, arā, he ātete ake te uku ki te polyethylene i te konganuku ki te polyethylene! Nō reira, ko te hononga hope horihori pai rawa atu, i runga i te rauemi anake, he hononga atanga uku-ki-uku. Ko te take o te roa o te ora o tēnei hononga he mea kua whakaitihia te tere pakaru e ngā tekau ki ngā rau wā ki ngā hononga o mua, ka roa ake te wā whakamahi hononga, ā, ko ngā matūriki pakaru he kohuke hototahi ki te tangata kāore e puta ai te osteolysis me te osteoporosis huri noa i te prosthesis, he pai ake mō ngā tūroro taitamariki he nui te mahi. 2. Te whakatakotoranga tika o te takai hope: mā te whakatakotoranga tika o te takai hope i te wā pokanga, ka taea te whakarite i te acetabulum me te kakau femur. Mā te pumau o te takai hope me te koki tika ka kore te takai hope e kukū, e hēke rānei, ā, kāore e wetekina te takai hope.
Te tiaki i ō rātou ake hononga hope: whakaitihia te pikaunga taumaha, ngā mahi uaua (pēnei i te piki me te pikaunga taumaha mō te wā roa, me ētahi atu) hei whakaiti i te pakaru me te haehae o te hononga hope. Hei tāpiri, āraihia ngā whara, nā te mea ka taea e te whara te arahi ki ngā whati huri noa i te hononga hope, ka arahi pea ki te wetewete o te hononga hope.
Nō reira, ko ngā prosthesis hope i hangaia mai i ngā rauemi iti ake te whakakoi, he tika te whakatakotoranga o tehononga hopeā, mā te tiakitanga e tika ana o te hononga hope ka roa ake te ora o te prosthesis, ahakoa mō te roanga o te ora.
