Ọkpụkpụ hip arthroplasty bụ usoro ịwa ahụ ka mma maka ọgwụgwọ necrosis isi femoral, osteoarthritis nke nkwonkwo úkwù, na mgbawa nke nkwonkwo úkwùfemoralolu n'ime agadi. Ọkpụkpụ úkwù bụ usoro tozuru okè ugbu a nke na-aghọwanye ewu ewu nke ukwuu ma enwere ike imecha ya ọbụna n'ụlọ ọgwụ ụfọdụ dị n'ime ime obodo. Ka ọnụọgụgụ ndị ọrịa na-agbanwe úkwù na-abawanye, ndị ọrịa na-enwekarị nchegbu banyere ogologo oge prosthesis ga-adịru mgbe a wachara úkwù ahụ na ma ọ ga-adịru ndụ niile. N'ezie, ogologo oge enwere ike iji nnọchi nkwonkwo úkwù mgbe a wachara ahụ dabere na akụkụ atọ bụ isi: 1, nhọrọ nke ihe: ugbu a enwere ihe atọ bụ isi maka nkwonkwo úkwù arụrụ arụ: ① isi seramiiki + iko seramiiki: ọnụ ahịa ga-adị elu. Isi uru nke njikọta a bụ na ọ na-eguzogide iyi karịa. Na esemokwu seramiiki na seramiiki, otu ibu, iyi na ndọda ma e jiri ya tụnyere njikọ ígwè dị obere, obere ihe fọdụrụ na oghere nkwonkwo n'ihi iyi na ndọda dịkwa obere nke ukwuu, n'ụzọ bụ isi, agaghị enwe mmeghachi omume ịjụ ahụ maka irighiri ihe ndị na-eyi. Agbanyeghị, n'ihe gbasara ọrụ siri ike ma ọ bụ ọnọdụ na-adịghị mma, enwere obere ihe egwu nke mgbawa seramiiki. E nwekwara obere ndị ọrịa ole na ole na-enweta ụda "na-akụ" nke esemokwu seramiiki kpatara n'oge ọrụ.
②Isi ígwè + iko polyethylene: akụkọ ihe mere eme nke ngwa ahụ dị ogologo ma bụrụ ngwakọta ochie karịa. Polyethylene polymer nke ígwè na nke dị elu, n'ozuzu ya anaghị apụta na ọrụ ahụ nwere mkpọtụ na-adịghị mma, ọ gaghịkwa agbawa agbawa na ihe ndị ọzọ. Agbanyeghị, ma e jiri ya tụnyere seramiiki na seramiiki, ọ na-eyi obere ihe karịa n'okpuru otu ibu ahụ maka otu oge. Na obere ọnụọgụgụ nke ndị ọrịa nwere mmetụta uche, ọ ga-emeghachi omume na ihe mkpofu emebi emebi, na-eme ka mbufụt gburugburu ihe mkpofu emebi emebi mee na nzaghachi, na-emekwa ka mgbu nwayọ nwayọ gburugburu prosthesis, na-ebelata prosthesis, wdg. ③ Isi ígwè + ihe mkpuchi ígwè: njikọ esemokwu ígwè na metal (cobalt-chromium alloy, mgbe ụfọdụ igwe anaghị agba nchara) Ejirila njikọ esemokwu a mee ihe na 1960s. Agbanyeghị, njikọ a nwere ike imepụta ọtụtụ ihe mkpofu ígwè emebi emebi, enwere ike iji macrophages phagocytose mee ihe, na-emepụta mmeghachi omume ahụ mba ọzọ, ion ígwè emepụtara nwekwara ike ịbanye n'ọbara, na-akpali mmeghachi omume nfụkasị ahụ n'ahụ. N'afọ ndị na-adịbeghị anya, a kwụsịla ụdị njikọ interface a. ④ Isi seramiiki ruo polyethylene: Isi seramiiki siri ike karịa ígwè ma bụrụ ihe kachasị egbochi ọkọ. Seramiiki a na-eji ugbu a n'ịwa ahụ nkwonkwo nwere elu siri ike, nke na-eguzogide ọkọ, nke dị nro nke ukwuu nke nwere ike ibelata ọsọ iyi nke njikọ esemokwu polyethylene nke ukwuu. Oke iyi nke ihe a na-etinye n'ime ihe a erughị metal na polyethylene, n'ikwu ya n'ụzọ ọzọ, seramiiki ruo polyethylene na-eguzogide iyi karịa metal na polyethylene! Ya mere, nkwonkwo úkwù kacha mma, naanị n'ihe gbasara ihe, bụ nkwonkwo seramiiki-na-seramiiki. Ihe kpatara ogologo ndụ nke nkwonkwo a bụ na ọnụego iyi na-ebelata ugboro iri ruo ọtụtụ narị ma e jiri ya tụnyere nkwonkwo ndị gara aga, na-agbatị oge ojiji nkwonkwo nke ukwuu, ihe ndị na-eyi bụ mineral ndị mmadụ na-ejikọta nke na-anaghị ebute osteolysis na osteoporosis gburugburu prosthesis, nke dabara adaba maka ndị ọrịa na-eto eto nwere nnukwu ọrụ. 2. Ntinye aka nke úkwù kpọmkwem: site na ntinye aka nke úkwù kpọmkwem n'oge ịwa ahụ, acetabulum na ogwe femoral. Ịkwụsi ike nke úkwù siri ike na akụkụ kwesịrị ekwesị na-eme ka úkwù ghara ịdị nkọ ma ọ bụ gbajie, si otú a ghara ime ka úkwù ahụ dajụọ.
Nchedo nke nkwonkwo úkwù ha: belata ibu ibu, ihe omume siri ike (dịka ịrịgo na ibu ibu ogologo oge, wdg) iji belata mmebi na ndọda nke prosthesis. Na mgbakwunye, gbochie mmerụ ahụ, n'ihi na mmerụ ahụ nwere ike ibute mgbawa gburugburu prosthesis úkwù, nke nwere ike ibute mbelata nke prosthesis.
Ya mere, e ji ihe ndị na-anaghị emebi emebi mee ihe ndị e ji úkwù rụọ, nke a na-etinye kpọmkwem n'ebe ahụ.nkwonkwo úkwùnchekwa dị mkpa nke nkwonkwo úkwù nwere ike ime ka ihe e ji arụ ọrụ ahụ dịgide ogologo oge, ọbụnadị ruo mgbe ọ ga-adị ndụ.
