Ezigulini ezizothatha indawo ye-hip noma ezicabangela ukushintshwa kwe-hip esikhathini esizayo, kunezinqumo eziningi ezibalulekile okufanele zenziwe. Isinqumo esibalulekile ukukhethwa kwendawo esekela yokufakelwa ukuze kufakwe indawo ehlangene: insimbi-on-metal, insimbi-on-polyethylene, i-ceramic-on-polyethylene, noma i-ceramic-on-ceramic. Ngezinye izikhathi, lokhu kungaba inkinga!
Ukuhlinzwa okuphelele kokubuyisela inqulu kungasetshenziswa ukufaka esikhundleni sejoyinti le-hip le-arthritic, kusetshenziswa i-prosthesis yelunga lokwenziwa ukuze kuqedwe ubuhlungu obubangelwa ukuhlikihlwa kwendawo.
Izitho zokwenziwa ezihlangene zenzelwe ukunikeza iziguli ukuzinza okukhulu kanye nokuguga okuncane. Izimila zendabuko zensimbi neze-polyethylene bezilokhu zisetshenziswa kusukela ngeminyaka yawo-1960, kodwa ukuthuthuka kwezobuchwepheshe kuholele ekutheni i-ceramic nezinye izinto ezisetshenziswayo zidume kakhulu.
Izinto zokufakelwa ezihlangene ze-Hip
Enye yezinkinga ezivame kakhulu ngemva kokushintshwa kwe-hip ukuguga kwe-joint prosthesis kusukela ekusetshenzisweni okuvamile. Kuye ngezimo ezithile zesiguli, njengeminyaka yobudala, ubukhulu, izinga lomsebenzi, kanye nolwazi lukadokotela ohlinzayo ngokufakela okuthile okukhethekile, ukufakelwa kwe-hip esikhundleni kungase kwenziwe ngensimbi, i-polyethylene (ipulasitiki), noma i-ceramic. Isibonelo, uma isiguli sisebenza kakhulu noma sisencane futhi sidinga izinga eliphezulu lokuhamba ngemva kokuhlinzwa, udokotela ohlinzayo wamathambo angase atuse ukufakelwa kwe-ceramic hip.
1,Ikhanda lebhola lensimbikanye ne-polyethylene (ipulasitiki).
Amabhola ensimbi ajwayelekile kanye ne-polyethylene cup liners bezilokhu zisetshenziswa kusukela ekuqaleni kwawo-1960. Ucwaningo lwesayensi lubonisa ukuthi ukusetshenziswa kwama-polyethylene liners athuthukisiwe, okwaziwa ngokuthi "highly cross-linked" polyethylene liners, kunganciphisa kakhulu izinga lokuguga lilonke lokufakelwa. Ngenxa yokuqina kwayo nezinye izici ezihlobene, i-polyethylene yensimbi ibe yinto ekhethwa odokotela abahlinzayo bamathambo ezingxenyeni ze-hip yokwenziwa kusukela kwenziwa ukuhlinzwa kokuqala esikhundleni se-hip. Ibhola lensimbi lenziwe nge-cobalt-chromium alloy futhi ulwelwesi lwenziwe nge-polyethylene.
2,Ikhanda lebhola le-Ceramickanye ne-polyethylene (ipulasitiki).
Amathiphu e-Ceramic aqinile kunensimbi futhi ayizinto zokufakelwa ezikwazi ukumelana kakhulu. Izithako zobumba ezisetshenziswa njengamanje ekuhlinzeni okuhlanganyelwe zinezindawo eziqinile, ezikwazi ukumelana nokuklwebheka, nezibushelelezi ezinganciphisa kakhulu izinga lokuguga lokuhlangana kwe-polyethylene friction. Izinga lokuguga okungenzeka lalokhu okufakwayo liphansi kunezinga lokuguga okungenzeka lensimbi ku-polyethylene.
3、 Ikhanda lebhola lensimbi kanye nomugqa wensimbi
I-Metal-on-metal friction interfaces (ama-cobalt-chromium alloys, ngezinye izikhathi insimbi engagqwali) iye yasetshenziswa kusukela ngo-1955, kodwa ayizange ivunyelwe yi-FDA ukuthi isetshenziswe e-United States kuze kube ngu-1999. Njengoba ubuchwepheshe buthuthuka, ukuguga kuncipha kakhulu, okuholela ekuvuvukeni okuncane nokulahlekelwa kwamathambo. Izinsimbi zensimbi zitholakala ngobukhulu obuhlukahlukene (kusukela ku-28mm kuya ku-60mm), kanye nezinhlobonhlobo zezinketho zobude bentamo. Kodwa-ke, imibiko yesikhathi eside yangemva kokuhlinzwa ibonisa ukuthi insimbi, njenge-ion esebenza ngokuqhathaniswa, iqoqa izinsalela zensimbi ngenxa yokuguga nokuklebhuka isikhathi eside, okungaholela ekuhlakazweni kwamathambo azungeze i-joint prosthesis, ekugcineni kuholele ekuxegisweni nokuguqulwa kwe-joint prosthesis. Umsebenzi wehlulekile.
4、 Ikhanda lebhola le-Ceramic kanyeindwangu ye-ceramic
Kulezi zinqulu, amabhola ensimbi endabuko kanye nama-polyethylene liners athathelwe indawo yi-ceramics yamandla aphezulu, aziwa ngezakhiwo zawo ezigqokwa kakhulu. Kodwa-ke, nakuba benezinzuzo zekhwalithi ephezulu kanye nokugqoka okuphansi, futhi nakanjani banesimo esibi sezindleko eziphezulu.
Ukukhethwa kokugcina kokufakelwa kuyonqunywa ngokusekelwe ezicini zezempilo zesiguli futhi kuzodinga ulwazi lukadokotela ohlinzayo wamathambo, imfundo, kanye nobuchwepheshe ukuze wenze umkhiqizo womkhiqizi othile ngokwezifiso. Ngakho-ke, kuyadingeka ukuxoxisana nodokotela wakho ohlinzayo wamathambo ngaphambi kokuhlinzwa ukuze uqonde uhlobo lokufakelwa abahlose ukukusebenzisa ukuhlinzwa kwakho esikhundleni se-hip, nezizathu zokukhetha ukufakelwa okuthile.
