II-JDS hip ithuluziimele intuthuko enkulu ekuhlinzeni kwamathambo, ikakhulukazi emkhakheni wokuhlinzwa kokufakelwa kwe-hip. Lawa mathuluzi aklanyelwe ukuthuthukisa ukunemba nokusebenza kahle kokuhlinzwa kokufakelwa kwe-hip, futhi enziwa ngokwezifiso ngokwezidingo ezishintsha njalo zodokotela abahlinzayo neziguli.
I-JDSithuluzi lokuhlangana kwenquluinesakhiwo esisha esenza inqubo yokuhlinzwa ibe lula. Le thuluzi lifaka isethi ephelele yamathuluzi okusiza ekubekeni ngokunembile umgodi we-hip joint, ukuqinisekisa ukuhambisana kahle kanye nokuqina. Lokhu kubalulekile empumelelweni yesikhathi eside ye-hip implants, njengoba ukubekwa kahle kunganciphisa kakhulu ingozi yezinkinga futhi kuthuthukise ukubikezela kwesiguli.
Isethi YesinqeUkusetshenziswa kanye Nezicelo Ekuhlinzeni Kwamathambo
Enye yezindlela eziyinhloko zokusebenzisaIzinsimbi zomculo ze-JDS hip jointi-total hip arthroplasty (THA), okuwukuhlinzwa okuvamile kweziguli ezine-arthritis noma ukwaphuka okukhulu kwe-hip. Le thuluzi lisiza odokotela abahlinzayo ukulungiselela ngokunembile i-hip socket kanye ne-femur ukuqinisekisa ukuhambisana kahle kanye nokuqina kwezitho ezifakelwe e-hip. Ukwakheka kwayo kwe-ergonomic kuvumela ukuguquguquka okukhulu, ngaleyo ndlela kunciphisa ingozi yezinkinga zokuhlinzwa.
Ingqikithi yeInsimbi yomculo ye-hipyi-femoral shaft uqobo, evame ukwenziwa ngezinto ezinamandla aphezulu njenge-titanium noma i-cobalt chromium alloy. Sikhethe lezi zinto ngenxa yokuhambisana kwazo kanye nokuqina kwazo ukuze zisetshenziswe isikhathi eside emzimbeni womuntu. I-femoral shaft inamathela eduze ku-femur, ihlinzeka ngesisekelo esiqinile sejoyinti lesinqe lokwenziwa.
Esinye isici esibalulekile yi-reamer, esetshenziselwa ukulungiselela ithubhu le-femoral le-femoral shaft. I-reamer iqinisekisa ukuthi ithubhu le-femoral linobukhulu nesimo esifanele, ngaleyo ndlela iqinisekisa ukuqina okuphephile kwe-femoral shaft. Lesi sinyathelo sibalulekile ekunciphiseni ingozi yezinkinga nokuqinisekisa ukuthi i-implant ihlala isikhathi eside.
Ngaphezu kwalokho, ikhithi yemishini ingafaka izingxenye ezahlukahlukene zokuhlola ezivumela odokotela abahlinzayo ukuthi bahlole osayizi abahlukene kanye nokuma ngaphambi kokufakelwa kokugcina. Inqubo yokugqoka ukuhlolwa ibalulekile ekufezeni ukubambisana nokusebenza kahle kwesiguli.
Ngamafuphi, iithuluzi lokuhlangana kwenquluIqukethe izingxenye eziningana ezibalulekile, okuhlanganisa i-femoral stem, i-reamer, umhlahlandlela wokulinganisa, kanye nokuhlolwa. Ingxenye ngayinye ibalulekile ekuqinisekiseni impumelelo yokuhlinzwa kokufakelwa kwe-hip, ekugcineni ithuthukise ukubikezela kwesiguli kanye nokuthuthukisa ikhwalithi yokuphila kweziguli ezinezifo ezihlobene ne-hip.
