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.Ngapha koko, ixesha elingakanani i-hip joint replacement ingasetyenziswa emva kotyando kuxhomekeke kwimiba emithathu ephambili: 1, ukhetho lwemathiriyeli: okwangoku kukho izinto ezintathu eziphambili zokudityaniswa kwe-hip yokwenziwa: ① intloko ye-ceramic + ikomityi ye-ceramic: iindleko ziya kuba ngokulinganayo. phezulu.Inzuzo ephambili yale ndibaniselwano kukuba ingaphezulu kokunxiba.Kwi-ceramic kunye ne-ceramic friction, umthwalo ofanayo, ukunxiba kunye nokukrazula ngokumalunga nojongano lwentsimbi mncinci kakhulu, kwaye amasuntswana amancinci ashiywe kumngxunya odibeneyo ngenxa yokuguga kunye nokukrazula kuncinci kakhulu, ngokusisiseko akuyi kubakho kusabela kokulahlwa 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 elincinci kakhulu lezigulane ezinovakalelo, iya kusabela kwi-debris egugileyo, ibangela ukudumba malunga nobutyobo obunxitywayo ukuba kwenzeke kwimpendulo, kwaye ngokuthe ngcembe iintlungu ezijikeleze i-prosthesis, i-prosthesis ikhulula, njl. ③ Intloko yentsimbi + intsimbi yentsimbi: isinyithi kwi-metal friction interface (i-cobalt-chromium alloy, ngamanye amaxesha insimbi engenasici) Le interface ye-friction isetyenziswe kwi-1960s.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 zokunxiba ziyiminerali ehambelana nomntu. kubangela 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 ingagxininisi kwaye ikhutshwe, ngaloo ndlela ingabangeli ukukhulula. iprothesis.

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.
