Kwizigulane ezifuna ukutshintshwa kwe-hip okanye ziqwalasela ukutshintshwa kwe-hip kwixesha elizayo, kukho izigqibo ezininzi ezibalulekileyo zokwenza. Isigqibo esibalulekileyo kukukhethwa kwendawo exhasayo yeprosthetic yokutshintshwa ngokubambisana: isinyithi-ngesinyithi, isinyithi-kwi-polyethylene, i-ceramic-on-polyethylene, okanye i-ceramic-on-ceramic. Ngamanye amaxesha, oku kunokuba yingxaki!
Utyando olupheleleyo lokutshintshwa kwe-hip lungasetyenziselwa ukutshintsha indawo ye-arthritic hip joint, usebenzisa i-prosthesis ye-artificial joint prosthesis ukuphelisa intlungu ebangelwa ukuxutywa kweendawo.
Iiprostheses ezihlangeneyo ezenziweyo zenzelwe ukubonelela izigulane ngokuzinza okukhulu kunye nokunxiba okuncinci kunye nokukrazula. Ukufakelwa kwentsimbi yesiNtu kunye ne-polyethylene sele isetyenziswe ukususela ngo-1960, kodwa inkqubela phambili yeteknoloji ikhokelele kwi-ceramic kunye nezinye izinto ezithandwa kakhulu.
Izixhobo zokufakelwa kwe-hip joint replacement
Enye yeengxaki eziqhelekileyo emva kokutshintshwa kwe-hip kukugqoka kunye nokukrazula kwe-joint prosthesis ukusuka kusetyenziso oluqhelekileyo. Ngokuxhomekeke kwiimeko ezithile zomguli, ezifana nobudala, ubungakanani, umgangatho womsebenzi, kunye namava ogqirha wotyando ngofakelo oluthile, i-hip replacement prosthesis inokwenziwa ngesinyithi, i-polyethylene (iplastiki), okanye i-ceramic. Ngokomzekelo, ukuba isigulane sisebenza kakhulu okanye sincinci kwaye sidinga inqanaba eliphezulu lokuhamba emva kokuhlinzwa, ugqirha wamathambo unokuncoma ukufakelwa kwe-ceramic hip.
1,Intloko yebhola yentsimbikunye ne-polyethylene (iplastiki) i-lining.
Iibhola zentsimbi eziqhelekileyo kunye ne-polyethylene cup liners ziye zasetyenziswa ukususela ekuqaleni kwe-1960s. Uphando lwezenzululwazi lubonisa ukuba ukusetyenziswa kwe-polyethylene liners eziphuculweyo, ezaziwa ngokuba "zii-highly cross-linked" i-polyethylene liners, kunokunciphisa kakhulu izinga lokunxiba lokufakelwa. Ngenxa yokuqina kwayo kunye nezinye iimpawu ezihambelanayo, i-polyethylene yensimbi ibe yinto ekhethiweyo yokuhlinzwa kwamathambo kumacandelo e-hip eyenziweyo ukususela ekubeni utyando lokuqala lokutshintshwa kwe-hip lwenziwa. Ibhola yentsimbi yenziwe nge-cobalt-chromium alloy kwaye i-lining yenziwe nge-polyethylene.
2,Intloko yebhola yeCeramickunye ne-polyethylene (iplastiki) i-lining
Iingcebiso zeCeramic zinzima kunentsimbi kwaye zezona zinto zifakelwayo zingakrwelekiyo. I-Ceramics okwangoku esetyenziswa kuqhaqho oludibeneyo lunemigangatho eqinile, engakrwelekiyo, negudileyo enokunciphisa kakhulu izinga lokunxitywa kwe-polyethylene friction interfaces. Umyinge onokuthi unxitywe wolu fakelo ungaphantsi kunomlinganiselo wokunxitywa kwesinyithi kwi-polyethylene.
3, Intloko yebhola yentsimbi kunye nelinen yentsimbi
I-Metal-on-metal friction interfaces (i-cobalt-chromium alloys, ngamanye amaxesha insimbi engenasici) isetyenziswe ekuqaleni kwe-1955, kodwa ayizange ivunywe yi-FDA ukuba isetyenziswe e-United States de kube ngu-1999. Njengoko iteknoloji iqhubela phambili, ukunxiba kuncitshiswe kakhulu, okubangela ukuvuvukala okuncinci kunye nokulahleka kwamathambo. Iintsimbi zentsimbi zifumaneka kwiindidi ezahlukeneyo (ukusuka kwi-28mm ukuya kwi-60mm), kunye neendlela ezahlukeneyo zobude bentamo. Nangona kunjalo, iingxelo zexesha elide emva kokuhlinzwa zibonisa ukuba isinyithi, njenge-ion esebenzayo, iqokelela i-debris yesinyithi ngenxa yokuguga kwexesha elide kunye nokukrazula, okunokubangela ukuchithwa kwethambo malunga ne-joint prosthesis, ekugqibeleni kukhokelela ekukhululweni kunye nokuguqulwa kwe-joint prosthesis. Umsebenzi awuphumelelanga.
4, Intloko yebhola yeCeramic kunyeulune lweceramic
Kulezi zinqunqa, iibhola zetsimbi zendabuko kunye ne-polyethylene liners ziye zatshintshwa yi-ceramics yamandla aphezulu, awaziwa ngokuba yi-ultra-low-wear properties. Nangona kunjalo, ngelixa zineenzuzo zomgangatho ophezulu kunye nokunxiba okuphantsi, ngokuqinisekileyo banakho ukungonakali kweendleko eziphezulu.
Ukhetho lokugqibela lofakelo luya kumiselwa ngokusekwe kwimiba ethile yempilo yesigulana kwaye kuya kufuna kwakhona ubuchule bogqirha wamathambo, imfundo, kunye nobuchule bokwenza imveliso yomenzi othile. Ngoko ke, kuyimfuneko ukuxoxa nodokotela wakho wamathambo ngaphambi kokuhlinzwa ukuze uqonde uhlobo lokufakelwa abazimisele ukulusebenzisa utyando lwakho lokutshintshwa kwe-hip, kunye nezizathu zokukhetha ukufakelwa okuthile.
