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-hip iisitshaloukuqeda ubuhlungu obubangelwa ukuhlikihla izindawo.
Inquluji-ointpi-rosthesiszenzelwe ukunikeza iziguli ukuzinza okukhulu kanye nokuguguleka okuncane. Izithako zendabuko zensimbi kanye ne-polyethylene bezilokhu zisetshenziswa kusukela ngawo-1960, kodwa intuthuko kwezobuchwepheshe iholele ekutheni izinto zobumba nezinye izinto zibe zithandwa kakhulu.
Ezokwelaphahip ji-ointizinto zokwakha.
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-Theoi-rthopedichip iizimilakungenziwa 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 ukufakelwa kwe-ceramic hip.
1. Ikhanda lebhola lensimbi kanye 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 kwama-implant. Ngenxa yokuqina kwayo kanye nezinye izakhiwo ezihlobene nayo, i-polyethylene yensimbi ibilokhu iyinto ekhethwa odokotela abahlinzayo bamathambo ukuzeaokwenziwayohip ji-ointselokhu kwenziwa ukuhlinzwa kokuqala kokufakwa kwesinqe. Ibhola lensimbi lenziwe nge-cobalt-chromium alloy kanti ulwelwesi lwenziwe nge-polyethylene.
2. Ikhanda lebhola le-ceramic kanye 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.
3,Ikhanda lebhola lensimbikanye 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.
4,Ikhanda lebhola le-ceramicfuthiulwelwesi lwe-ceramic
Kuleziaokwenziwayohip ji-ointsisistimus, amabhola ensimbi endabuko kanye nama-polyethylene liner athathelwe indawo yi-ceramics enamandla kakhulu, eyaziwa ngezakhiwo zayo ezigugile kakhulu. Kodwa-ke, yize inezinzuzo zekhwalithi ephezulu kanye nokugugile okuncane, futhi ngokungenakugwenywa inezinkinga zezindleko eziphakeme.
Ukukhetha kokugcinahip ji-ointiisitshalokuzonqunywa 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 kokufakelwa kwenqulu, kanye nezizathu zokukhetha ukufakelwa okuthile.
Uma ufuna ukufunda kabanzi mayelana ne- i-prosthesis yesinqeulwazi, sicela ukhululekeXhumana nathi; ithimba lethu lizokunikeza ukwesekwa kochwepheshe kanye nezimpendulo.
