Ingaba i-hip replacement prosthesis ihlala ixesha elingakanani?

I-Hip arthroplasty yinkqubo yotyando engcono yokunyanga i-necrosis yentloko ye-femoral, i-osteoarthritis ye-joint hip, kunye nokwaphuka kwethambo.femoralintamo kwiminyaka yobudala. I-Hip arthroplasty ngoku yinkqubo ekhulileyo ngokuthe ngcembe ifumana ukuthandwa kwaye inokugqitywa nakwezinye izibhedlele zasemaphandleni. Ngokunyuka kwenani lezigulane zokutshintshwa kwe-hip, izigulane zihlala zixhalabile malunga nokuba ixesha elingakanani i-prosthesis iya kuhlala emva kokuhlinzwa kokutshintshwa kwe-hip kunye nokuba kuya kuhlala ubomi bonke. Enyanisweni, ixesha elingakanani ukutshintshwa kwe-hip joint replacement ingasetyenziswa emva kokuhlinzwa kuxhomekeke kwimiba emithathu ephambili: 1, ukhetho lwezixhobo: okwangoku kukho izinto ezintathu eziphambili zokudibanisa i-hip joint: ① intloko ye-ceramic + ikomityi ye-ceramic: ixabiso liya kuba liphezulu kakhulu. Inzuzo ephambili yale ndibaniselwano kukuba ingaphezulu kokunxiba. Kwi-ceramic kunye ne-ceramic friction, umthwalo ofanayo, ukunxiba kunye nokukrazula ngokumalunga ne-metal interface kuncinci kakhulu, kwaye amasuntswana amancinci ashiywe kwindawo edibeneyo ngenxa yokuguga kunye nokukrazula kuncinci kakhulu, ngokusisiseko akuyi kubakho ukusabela kokwaliwa komzimba ukunxiba amasuntswana. Nangona kunjalo, kwimeko yomsebenzi onzima okanye ukungahambi kakuhle, kukho umngcipheko omncinci wokuqhekeka kwe-ceramic. Kukho nezigulane ezimbalwa kakhulu ezifumana isandi esithi "creaking" esibangelwa yi-ceramic friction ngexesha lomsebenzi.

②Intloko yentsimbi + ikomityi yepolyethylene: imbali yesicelo inde kwaye iyindibaniselwano yakudala. Isinyithi ukuya kwi-ultra-high polymer polyethylene, ngokuqhelekileyo ayibonakali kumsebenzi ine-rattle engaqhelekanga, kwaye ayiyi kuphuka njalo njalo. Nangona kunjalo, xa kuthelekiswa ne-ceramic ukuya kwi-fraction interface ye-ceramic, inxiba kancinci ngaphantsi komthwalo ofanayo ngexesha elinye. Kwaye kwinani elincinane kakhulu lezigulane ezinovakalelo, liya kusabela kwi-debris egugileyo, ebangela ukudumba malunga nokungcola okunxitywayo ukuba kwenzeke kwimpendulo, kwaye ngokuthe ngcembe iintlungu zijikeleze i-prosthesis, i-prosthesis ikhulula, njl. Nangona kunjalo, olu nxibelelwano lunokuvelisa inani elikhulu lamaqhekeza esinyithi, la masuntswana anokuthi afakwe kwi-phagocytosed yi-macrophages, avelise ukusabela komzimba wangaphandle, ukunxiba ii-ion zetsimbi ezenziweyo zinokungena egazini, okubangela ukusabela komzimba. Kwiminyaka yakutshanje, olu hlobo lwe-interface joints luyekiwe. ④ Intloko yeCeramic kwi-polyethylene: Iintloko ze-ceramic zinzima kunentsimbi kwaye zezona zinto zifakelwayo zingakrwelekiyo. I-ceramic esetyenziswa ngoku kuqhaqho lokudityaniswa kwendawo yotyando inomphezulu oqinileyo, ongakrwelekiyo, ogudileyo kakhulu onokulinciphisa kakhulu izinga lokunxitywa kwe-polyethylene friction interfaces. Umyinge wokunxitywa okunokwenzeka kolu kufakelwa ungaphantsi kwesinyithi kwi-polyethylene, ngamanye amagama, i-ceramic ukuya kwi-polyethylene ithiyori iyaxhathisa ngakumbi kunentsimbi kwi-polyethylene! Ke ngoko, eyona nto ilungileyo yokwenziwa kwe-hip joint, ngokwezinto eziphathekayo, yi-ceramic-to-ceramic interface joint. Isizathu sobomi obude benkonzo yalo mdibaniso kukuba izinga lokunxiba lincitshiswe ngamashumi amaxesha ukuya kumakhulu amaxesha xa kuthelekiswa namalungu angaphambili, ukwandisa kakhulu ixesha lokusetyenziswa ngokubambisana, kunye neengqungquthela zokugqoka ziyiminerali ehambelana nomntu engabangeli i-osteolysis kunye ne-osteoporosis ejikeleze i-prosthesis, efanelekileyo ngakumbi kwizigulane ezincinci ezinomsebenzi ophezulu. 2. Ukubekwa ngokuchanekileyo kwe-hip prosthesis: ngokubekwa ngokuchanekileyo kwe-prosthesis ngexesha lotyando, i-acetabulum kunye ne-femoral stalk Ukulungiswa okuqinileyo kwe-prosthesis kunye ne-angle efanelekileyo kwenza ukuba i-prosthesis ingagxininiswa kwaye ikhutshwe, ngaloo ndlela ingabangeli ukukhulula i-prosthesis.

Ukukhuselwa kwe-hip joint yabo: ukunciphisa ubunzima, imisebenzi enzima (njengokunyuka kunye nexesha elide lokuthwala ubunzima, njl. njl.) Ukunciphisa ukuchithwa kwe-prosthesis. Ukongezelela, ukuthintela ukulimala, kuba ukuxhwaleka kunokukhokelela ekuqhekekeni kwe-hip prosthesis, enokubangela ukukhululeka kweprosthesis.

Ngoko ke, i-hip prostheses eyenziwe ngezinto ezinqabileyo ezincinci, ukubekwa okuchanekileyo kwei-hip jointkunye nokukhuselwa okuyimfuneko kwe-hip joint kunokwenza i-prosthesis ihlale ixesha elide, nangona ubomi bonke.
