Kwizigulane eziza kufakelwa isinqe okanye ezicinga ngokufakelwa isinqe kwixesha elizayo, kukho izigqibo ezininzi ezibalulekileyo ekufuneka zenziwe. Isigqibo esibalulekileyo kukukhetha umphezulu oxhasayo we-prosthetic ukuze kufakwe isinqe: isinyithi-kwisinyithi, isinyithi-kwi-polyethylene, i-ceramic-kwi-polyethylene, okanye i-ceramic-kwi-ceramic. Ngamanye amaxesha, oku kunokuba yingxaki!
Utyando lokutshintshwa kwesinqe lonke lungasetyenziswa ukutshintsha isihlunu se-arthritis, kusetyenziswahip iisityalo esifakelweyoukuphelisa iintlungu ezibangelwa kukukhuhla iindawo ezikuyo.
Inquluji-ointpi-rosthesiszenzelwe ukubonelela izigulane ngozinzo olukhulu kunye nokungonakali kakhulu. Izixhobo zemveli zesinyithi kunye ne-polyethylene zisetyenziswe ukusukela ngeminyaka yoo-1960, kodwa inkqubela phambili kwezobuchwepheshe ikhokelele ekubeni izinto ze-ceramic kunye nezinye izinto zithandwa kakhulu.
Ezonyangohip ji-ointizixhobo.
Enye yezona ngxaki zixhaphakileyo emva kokutshintshwa kwesinqe kukuguguleka kwelungu lokufakelwa amalungu ngenxa yokusetyenziswa kwesiqhelo. Ngokuxhomekeke kwiimeko ezithile zesigulana, ezinje ngobudala, ubungakanani, inqanaba lomsebenzi, kunye namava kagqirha ngesixhobo esithile sokufakelwa, i-Theoi-rhetopedichip iizityalo ezifakelweyoingenziwa ngesinyithi, i-polyethylene (iplastiki), okanye i-ceramic. Umzekelo, ukuba isigulana sisebenza kakhulu okanye siselula kwaye sifuna ukuhambahamba okuphezulu emva kotyando, ugqirha wamathambo unokucebisa ukuba kufakwe i-ceramic hip implant.
1. Intloko yebhola yesinyithi kunye ne-polyethylene (iplastiki) yelayini
Iibhola zesinyithi eziqhelekileyo kunye nee-polyethylene cup liner bezisetyenziswa ukususela ekuqaleni kweminyaka yoo-1960. Uphando lwenzululwazi lubonisa ukuba ukusetyenziswa kwee-polyethylene liner eziphuculweyo, ezaziwa ngokuba zii-polyethylene liners “ezixhumene kakhulu”, kunokunciphisa kakhulu izinga lokuguguleka kwee-implants. Ngenxa yokuqina kwayo kunye nezinye iimpawu ezinxulumene noko, i-polyethylene yesinyithi ibisoloko iyinto ekhethwayo koogqirha bamathambo ukuze banyange.ayokwenyanihip ji-ointukusukela oko kwenziwa utyando lokuqala lokutshintshwa kwesinqe. Ibhola yesinyithi yenziwe nge-cobalt-chromium alloy kwaye ulwelo lwenziwe nge-polyethylene.
2, intloko yebhola yeseramikhi kunye ne-polyethylene (iplastiki) yelayini
Iincam zeseramikhi ziqinile kunesinyithi kwaye zezona zinto zokufakelwa ezikwaziyo ukumelana nokukrweleka. Iiseramikhi ezisetyenziswa ngoku kwiindlela zokutshintshwa kwamalungu zineendawo eziqinileyo, ezikwaziyo ukumelana nokukrweleka, ezigudileyo kakhulu ezinokunciphisa kakhulu izinga lokuguguleka kweendawo zokungqubana kwepolyethylene. Izinga lokuguguleka elinokwenzeka kwesi sifakelo liphantsi kunezinga lokuguguleka elinokwenzeka lesinyithi kwipolyethylene.
3,Intloko yebhola yesinyithikunye ne-liner yesinyithi
Ii-interfaces ze-metal-on-metal friction (ii-cobalt-chromium alloys, ngamanye amaxesha i-stainless steel) bezisetyenziswa kwasekuqaleni kowe-1955, kodwa azizange zivunywe yi-FDA ukuba zisetyenziswe e-United States de kwaba ngu-1999. Njengoko ubuchwepheshe buqhubeka, ukuguguleka kuyancipha kakhulu, nto leyo ebangela ukudumba okuncinci kunye nokulahleka kwamathambo. Ii-bearings zesinyithi ziyafumaneka ngobukhulu obahlukeneyo (ukusuka kwi-28mm ukuya kwi-60mm), kunye neendlela ezahlukeneyo zobude bentamo. Nangona kunjalo, iingxelo zexesha elide emva kotyando zibonisa ukuba isinyithi, njenge-ion esebenzayo, iqokelela inkunkuma yesinyithi ngenxa yokuguguleka kwexesha elide, okunokukhokelela ekuqhekekeni kwamathambo ajikeleze i-prosthesis yamalungu, ekugqibeleni okukhokelela ekukhululekeni nasekuguqulweni kwe-prosthesis yamalungu. Olu tyando aluphumelelanga.
4,Intloko yebhola yeseramikhikwayeumgca weseramikhi
Kweziayokwenyanihip ji-ointsinkqubos, iibhola zesinyithi zemveli kunye nee-polyethylene liners zithathelwe indawo zizinto zodongwe ezinamandla aphezulu, ezaziwa ngokuba neempawu zazo zokungagugi kakhulu. Nangona kunjalo, nangona zineengenelo zomgangatho ophezulu kunye nokungagugi kakhulu, zikwanazo neengxaki zexabiso eliphezulu.
Ukhetho lokugqibela lwehip ji-ointiisityalo esifakelweyoiya kugqitywa ngokusekelwe kwimiba ethile yempilo yesigulana kwaye iya kufuna ubuchule, imfundo, kunye nobuchule bogqirha wamathambo ukuze enze ngokwezifiso imveliso yomenzi othile. Ke ngoko, kubalulekile ukuxoxa nogqirha wakho wamathambo ngaphambi kotyando ukuze uqonde uhlobo lwe-implant aceba ukuyisebenzisa kutyando lwakho lokutshintsha i-hip, kunye nezizathu zokukhetha i-implant ethile.
