I-TKA Prosthesis- LDK X4 Primary Total Knee Arthroplasty

Incazelo emfushane:

Izimila ze-X4 edolweni zisetshenziselwa ukuqeda izikhalazo zesiguli mayelana namalunga amadolo akhubazekile noma akhubazekile, ngaphandle nje kweziguli ezinezinga lempilo elinciphile elibangelwa ubuhlungu obuhlobene ne-arthrosis.Ama-prostheses ahlangene edolo ahlanganisa izingxenye ezilandelayo;izingxenye zesifazane, ukufakwa, izingxenye ze-tibial, iziqu, izikhonkwane, amantongomane, izingxenye ze-patellar.

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

I-condyle yangaphambili ye-femoral prosthesis inikezwa ngobubanzi obuncishisiwe nokuqina ukuze kwehliswe ingcindezi ye-condyloid yangaphambili kanye nokungezwani kwe-quadriceps.I-geometry ye-sagittal efanayo kanye ne-curvature ebushelelezi ivumela i-patella ukuthi ingakhulisi amandla e-quadriceps femoris lapho idolo linwebeka futhi liguquguquka.Ngokuhambisana ne-patellar trochlear groove ejulile, kungaqinisekiswa ukuthi i-patella izinzile futhi i-groove ngisho nokuguquguquka okuphezulu ngaphandle kokukhishwa, futhi ukuxhumana okuqinile phakathi kwe-patella ne-femoral prosthesis kugcinwa ngaso sonke isikhathi.

I-femoral prosthesis iklanywe ngendiza ye-coronal egobile kancane ukuze kwandiswe indawo yokuxhumana ukuze kuncishiswe ukucindezela okuphezulu kokufakwa kwe-polyethylene.I-point-to-point edge bearing iqedwa ngesikhathi sokujikeleza kwe-varus-valgus emadolweni, ukuze i-tibiofemoral joint ihlale igcina ukuthintana ubuso nobuso.

I-patellar notch yangaphambili ye-polyethylene insert inciphisa ingcindezi eyengeziwe kanye nengcindezi ku-quadriceps femoris ngesikhathi sokuguquguquka okuphezulu.

I-posterior condylar curvature iyanda.I-tibiofemoral articular surface ihlala ithintana phezulu kunokuthintana lapho i-flexion ifinyelela ku-135 degrees.

Vula i-intercondylar fossa design: I-intercondylar osteotomy iyancishiswa, futhi ithambo lilondolozwe ngezinga elikhulu kakhulu lesiguli.

Isakhiwo se-cam-post esilungiselelwe: Ikhamera isagcinwe phansi kwekholomu ngenkathi idolo lisezingeni eliphezulu, livimbela ukuvela kokukhishwa komlomo wesibeletho ngesikhathi sokuhamba okuphezulu kuze kube sezingeni elilinganiselwe.

Umshini wokukhiya ohlukile unikeziwe.Ukulungiswa kwesibili okunamahange ensimbi kungaqeda ukugqokwa kwe-fretting phakathi kwakho kokubili.

Isakhiwo samaphiko amathathu sivimbela ukujikeleza futhi sigwema ukugxila kwengcindezi.
