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 isinqe esinamahlwili, kusetyenziswa i-prosthesis yokufakelwa kwesinqe ukuphelisa iintlungu ezibangelwa kukukhuhla iindawo ezisikiweyo.
Iiprosthesi zokufakelwa ezidibeneyo zenzelwe 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.
Izinto zokufakelwa kwe-hip endaweni ye-hip joint
Enye yezona ngxaki zixhaphakileyo emva kokutshintshwa kwesinqe kukuguguleka kwe-joint prosthesis ngenxa yokusetyenziswa okuqhelekileyo. Ngokuxhomekeke kwiimeko ezithile zesigulana, ezinje ngobudala, ubungakanani, inqanaba lomsebenzi, kunye namava kagqirha nge-implant ethile, i-hip prosthesis inokwenziwa ngesinyithi, i-polyethylene (iplastiki), okanye i-ceramic. Umzekelo, ukuba isigulana sisebenza kakhulu okanye siselula kwaye sifuna inqanaba eliphezulu lokuhamba emva kotyando, ugqirha wamathambo unokucebisa i-ceramic hip implant.
1、Intloko yebhola yesinyithikunye ne-polyethylene (iplastiki) yelineni.
Iibhola zesinyithi eziqhelekileyo kunye nee-polyethylene cup liner bezisetyenziswa ukususela ekuqaleni kweminyaka yoo-1960. Uphando lwenzululwazi lubonisa ukuba ukusetyenziswa kwee-polyethylene liners 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 kwiinxalenye ze-hip ezenziweyo ukusukela oko kwenziwa utyando lokuqala lokutshintshwa kwe-hip. Ibhola yesinyithi yenziwe nge-cobalt-chromium alloy kwaye i-lining yenziwe nge-polyethylene.
2、Intloko yebhola yeseramikhikunye ne-polyethylene (iplastiki) yelineni
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.
3Intloko yebhola yentsimbi kunye ne-liner yentsimbi
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 yeCeramic kunyeumgca weseramikhi
Kwezi hips, iibhola zesinyithi zemveli kunye nee-polyethylene liners zithathelwe indawo zizinto zeseramikhi ezinamandla aphezulu, ezaziwa ngokuba neempawu zazo zokungagugi kakhulu. Nangona kunjalo, nangona zinezibonelelo zomgangatho ophezulu kunye nokungagugi kakhulu, ngokuqinisekileyo zikwanazo neengxaki zexabiso eliphezulu.
Ukhetho lokugqibela lokufakelwa kwe-implant luya kugqitywa ngokusekelwe kwimiba ethile yempilo yesigulana kwaye kuya kufuna ubuchule, imfundo, kunye nobuchule bogqirha we-orthopedic ukuze enze ngokwezifiso imveliso yomenzi othile. Ke ngoko, kubalulekile ukuxoxa nogqirha wakho we-orthopedic ngaphambi kotyando ukuze uqonde uhlobo lokufakelwa kwe-implant abaceba ukulisebenzisa kutyando lwakho lokutshintsha i-hip, kunye nezizathu zokukhetha i-implant ethile.
