Ukwabelana Ngetyala Lezonyango-Ukutshintshwa kweLungu leSinqe
● Ulwazi oluSisiseko: Nksz. Chen, ibhinqa, oneminyaka engama-92 ubudala.
● Inkcazo emfutshane yeSimo: Kwiminyaka emihlanu eyadlulayo, ngengozi wawa waza wafumana iintlungu esinqeni sasekhohlo. Waphumla ekhaya kwaye iintlungu zaphela. Kwinyanga ephelileyo, iintlungu zesinqe sasekhohlo somguli zanda. Ekuqaleni kukaFebruwari kulo nyaka, isigulana satyelela iSibhedlele saseTongliang District saseChongqing saza sangeniswa kwiCandelo eliHlangeneyo 1 leSebe leeOrthopedics ngenxa “yokwaphuka kohlobo oludala kwentamo yasekhohlo yefemoral; i-necrosis yentloko yasekhohlo yefemoral; uxinzelelo lwegazi; isifo sentliziyo”.
● Uvavanyo oluNcedisayo: Uvavanyo lwe-CT, uvavanyo lwe-X-ray
● Ukuxilongwa kwangaphambi kotyando: Ukwaphuka kwentamo yekhohlo ye-femoral okuqhelekileyo; i-necrosis yentloko ye-femoral yasekhohlo
● Isicwangciso Sonyango: Ukutshintshwa kwe-hip epheleleyo yecala lasekhohlo
● Ukugqitywa kotyando: Phantsi kwesikhokelo sikagqirha, i-hip joint prosthesis evela eBeijing Zhongantaihua (ZATH) yafakelwa ngempumelelo. Utyando lwagqitywa kakuhle kwaye iimpawu ezibalulekileyo zesigulana zizinzile.
Ziziphi iintlobo zeeprostheses ze-hip ezikhoyo?
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 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 ibiyeyona nto ikhethwayo koogqirha bamathambo kwi-hip joint yokwenziwa ukusukela oko kwenziwa utyando lokuqala lokutshintshwa kwe-hip. Ibhola yesinyithi yenziwe nge-cobalt-chromium alloy kwaye i-lining yenziwe 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 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 kunye ne-ceramic lining
Kwezi nkqubo zokwenziwa kwe-hip joint, iibhola zesinyithi zemveli kunye nee-polyethylene liners zithathelwe indawo zi-ceramics ezinamandla aphezulu, ezaziwa ngeempawu zazo zokungagugi kakhulu. Nangona kunjalo, nangona zineengenelo zomgangatho ophezulu kunye nokungagugi kakhulu, zikwanazo neengxaki zexabiso eliphezulu.
