Ukwabelana Ngecala Lomtholampilo-Ukufakwa Kwejoyinti Le-Hip
● Ulwazi Oluyisisekelo: UNksz Chen, owesifazane, oneminyaka engu-92 ubudala.
● Incazelo Emfushane Yesimo: Eminyakeni emihlanu edlule, wawa ngephutha futhi wezwa ubuhlungu esinqeni sesobunxele. Waphumula ekhaya futhi ubuhlungu baphela. Enyangeni edlule, ubuhlungu besinqe sesobunxele sesiguli banda kakhulu. Ekuqaleni kukaFebhuwari kulo nyaka, isiguli savakashela iSibhedlela saseTongliang District saseChongqing futhi sangeniswa eMnyangweni Ohlangene 1 woMnyango Wezamathambo ngenxa “yokuphuka kohlobo oludala kwentamo yesobunxele ye-femoral; i-necrosis yekhanda lesobunxele le-femoral; umfutho wegazi ophakeme; isifo senhliziyo”.
● Ukuhlolwa Okusizayo: Ukuhlolwa kwe-CT, ukuhlolwa kwe-X-ray
● Ukuxilongwa Kwangaphambi Kokuhlinzwa: Ukuphuka kwentamo yesobunxele ye-femoral okuvamile; i-necrosis yekhanda lesobunxele le-femoral
● Uhlelo Lokwelapha: Ukufakwa kabusha kwesinqe okuphelele kohlangothi lwesobunxele
● Ukuqeda Ukuhlinzwa: Ngaphansi kwesiqondiso sikadokotela, i-prosthesis ye-hip joint evela eBeijing Zhongantaihua (ZATH) yafakwa ngempumelelo. Ukuhlinzwa kwaqedwa kahle futhi izimpawu ezibalulekile zesiguli zizinzile.
Yiziphi izinhlobo ze-hip prostheses ezikhona?
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 kwe-implants. Ngenxa yokuqina kwayo kanye nezinye izakhiwo ezihlobene nayo, i-polyethylene yensimbi ibilokhu iyinto ekhethwa odokotela abahlinzayo bamathambo ejoyintini le-hip elenziwe ngokwenziwa selokhu kwenziwa ukuhlinzwa kokuqala kokufakwa esikhundleni kwe-hip. 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 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.
4, ikhanda lebhola le-Ceramic kanye nolwelwesi lwe-ceramic
Kulezi zinhlelo zokwenziwa kwe-hip joint, 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 nokugugileka okuphansi, futhi ngokungenakugwenywa inezinkinga zezindleko eziphakeme.
Uma ufuna ukufunda kabanzi mayelana ne- i-prosthesis yesinqeulwazi, sicela ukhululekeXhumana nathi; ithimba lethu lizokunikeza ukwesekwa kochwepheshe kanye nezimpendulo.
