Ezigulini ezizofakelwa isinqe noma ezicabanga ngokufakelwa isinqe esikhathini esizayo, kunezinqumo eziningi ezibalulekile okufanele zithathwe. Isinqumo esibalulekile ukukhetha indawo esekelayo yokufakelwa ukuze kufakwe isinqe: insimbi phezu kwensimbi, insimbi phezu kwe-polyethylene, i-ceramic-on-polyethylene, noma i-ceramic-on-ceramic. Ngezinye izikhathi, lokhu kungaba yinkinga!
Ukuhlinzwa kokushintsha i-hip okuphelele kungasetshenziswa ukufaka esikhundleni se-arthritis hip joint, kusetshenziswa i-prosthesis yokufakelwa ukuze kuqedwe ubuhlungu obubangelwa ukuhlikihla izindawo.
Izitho zokufakelwa ezihlangene zokwenziwa zenzelwe ukunikeza iziguli ukuzinza okukhulu kanye nokuguguleka okuncane. Izitho zokufakelwa zensimbi neze-polyethylene zendabuko bezilokhu zisetshenziswa kusukela ngawo-1960, kodwa intuthuko kwezobuchwepheshe iholele ekutheni izinto zobumba nezinye izinto zibe zithandwa kakhulu.
Izinto zokufakelwa kwejoyinti lesinqe
Enye yezinkinga ezivame kakhulu ngemva kokufakelwa i-hip ukuguguleka kwe-prosthesis yamalunga ngenxa yokusetshenziswa okuvamile. Kuye ngezimo ezithile zesiguli, njengobudala, usayizi, izinga lomsebenzi, kanye nolwazi lukadokotela ohlinzayo nge-implant ethile, i-prosthesis yokufaka i-hip esikhundleni ingenziwa ngensimbi, i-polyethylene (ipulasitiki), noma i-ceramic. Isibonelo, uma isiguli sisebenza kakhulu noma sisesincane futhi sidinga izinga eliphezulu lokuhamba ngemva kokuhlinzwa, udokotela ohlinzayo wamathambo angancoma i-implant ye-ceramic hip.
1、Ikhanda lebhola lensimbikanye nolwelwesi lwe-polyethylene (ipulasitiki).
Amabhola ensimbi ajwayelekile kanye nama-polyethylene cup liner abelokhu esetshenziswa kusukela ekuqaleni kwawo-1960. Ucwaningo lwesayensi lubonisa ukuthi ukusetshenziswa kwama-polyethylene liner athuthukisiwe, aziwa ngokuthi ama-polyethylene liner "axhumene kakhulu", kunganciphisa kakhulu izinga lokuguguleka kwe-implants. Ngenxa yokuqina kwayo kanye nezinye izakhiwo ezihlobene nayo, i-polyethylene yensimbi ibilokhu iyinto ekhethwa odokotela abahlinzayo bamathambo bezingxenye ze-hip zokwenziwa selokhu kwenziwa ukuhlinzwa kokuqala kokufaka esikhundleni se-hip. Ibhola lensimbi lenziwe nge-cobalt-chromium alloy kanti ulwelwesi lwenziwe nge-polyethylene.
2、Ikhanda lebhola le-ceramickanye nolwelwesi lwe-polyethylene (ipulasitiki)
Ama-ceramic aphezu aqinile kunensimbi futhi ayizinto zokufakelwa ezimelana nokuklwebheka kakhulu. I-ceramics esetshenziswa njengamanje ekuhlinzeni okufakwe esikhundleni samalunga inezindawo eziqinile, ezingaklwebheka, ezibushelelezi kakhulu ezinganciphisa kakhulu izinga lokuguguleka kwezindawo zokungqubuzana ze-polyethylene. Izinga lokuguguleka okungenzeka kwalesi simila liphansi kunezinga lokuguguleka okungenzeka kwensimbi ku-polyethylene.
3Ikhanda lebhola lensimbi kanye ne-liner yensimbi
Izixhumi zokungqubuzana kwensimbi (ama-cobalt-chromium alloys, ngezinye izikhathi insimbi engagqwali) bezisetshenziswa kusukela ngo-1955, kodwa azizange zivunyelwe yi-FDA ukuthi zisetshenziswe e-United States kwaze kwaba ngu-1999. Njengoba ubuchwepheshe buthuthuka, ukuguguleka kuncipha kakhulu, okuholela ekuvuvukeni okuncane kanye nokulahlekelwa amathambo. Ama-bearings ensimbi atholakala ngobukhulu obuhlukahlukene (kusukela ku-28mm kuya ku-60mm), kanye nezinketho ezahlukene zobude bentamo. Kodwa-ke, imibiko yesikhathi eside yangemva kokuhlinzwa ikhombisa ukuthi insimbi, njenge-ion esebenzayo, iqoqa imfucumfucu yensimbi ngenxa yokuguguleka kwesikhathi eside, okungaholela ekuqhekekeni kwamathambo eduze kwe-prosthesis yamalunga, ekugcineni okuholela ekukhululekeni nasekuguqukeni kwe-prosthesis yamalunga. Ukuhlinzwa kwehlulekile.
4Ikhanda lebhola le-Ceramic kanyeulwelwesi lwe-ceramic
Kulezi zinqe, amabhola ensimbi endabuko kanye nama-polyethylene liner athathelwe indawo yi-ceramics enamandla kakhulu, eyaziwa ngezakhiwo zayo eziphansi kakhulu. Kodwa-ke, yize inezinzuzo zekhwalithi ephezulu kanye nokungagugi kahle, futhi ngokungenakugwenywa inezinkinga zezindleko eziphakeme.
Ukukhetha kokugcina kokufakelwa kuzonqunywa ngokusekelwe ezicini ezithile zempilo yesiguli futhi kuzodinga nobuchwepheshe bukadokotela wamathambo, imfundo, kanye nobuchwepheshe ukuze enze ngokwezifiso umkhiqizo womkhiqizi othile. Ngakho-ke, kubalulekile ukuxoxa nodokotela wakho wamathambo ngaphambi kokuhlinzwa ukuze uqonde uhlobo lokufakelwa abahlose ukulisebenzisa ekuhlinzeni kwakho esikhundleni senqulu, kanye nezizathu zokukhetha ukufakelwa okuthile.
