Icandelo le-Femoral Condyle prosthetic knee joint

Sikunika iinkqubo zamadolo ezigobileyo ezisebenza ngokugoba okuphezulu, iinkqubo zamadolo ezithintelayo kunye neeprostheses zamadolo ezenziwe ngokwezifiso. Iprosthesis epheleleyo yokutshintshwa kwedolo idla ngokuba neqakala le-femoral, itreyi ye-tibial, kunye ne-tibial pad. Izinto zayo ziyafumaneka kwiindlela ezahlukeneyo zokuhlangabezana neemfuno zonyango.
Inkqubo yokudibanisa idolo egobileyo ephezulu: uyilo lwebhokisi evulekileyo ngasemva, igcina umthamo wamathambo, igcina ukuqhubeka kwethambo le-cortical elingaphambili, uyilo oluncinci oluyi-J lwe-malleolus engasemva ye-femur, uyilo lwe-cam olulungiselelweyo, olulungele ukugoba okuphezulu, i-ridge ye-3-degree yetreyi ye-tibial medullary cavity stem Uyilo lwetreyi ye-tibial egobileyo emva, olune-anatomical luyandisa ukugquma komphezulu we-tibial osteotomy, luphucula isithuba se-tibial spacer, kwaye lunyusa ukuqengqeleka kwe-femoral xa igobile phezulu. I-tibial spacer i-chamfered ngaphambili ukunciphisa impembelelo ye-patella ngexesha lokugoba okunzulu. Umngxuma we-trochlear we-ankle ye-femoral inde, inzulu kwaye isemacaleni ukuze ilungelelanise indlela ye-femur, enokunciphisa ukulingana ngokubanzi kwe-prosthesis yejoyinti yedolo.
Inkqubo yokudibanisa idolo ethintelweyo: ifanelekile ekutshintsheni idolo eliphambili elintsonkothileyo kunye nokutshintshwa kwedolo, ilungele ukungazinzi ecaleni kunye nezikhewu zokujika, i-J-curve, uyilo lwe-multi-radius oluhambelana nomzimba womntu, olusetyenziswa kunye nenaliti ye-medulla ukubuyisela idolo. Uzinzo, uyilo lokunwebeka emva kokwandiswa kunye nokuphakama, luqonda umda wokujika komhlaba wangaphakathi nowangaphandle ± iidigri eziyi-1.2, ukujikeleza kwangaphakathi nangaphandle ± iidigri eziyi-2, uyilo lwetreyi ye-tibial elinganayo, i-angle ye-retroversion ye-0 degree, ukubuyiselwa okungcono kokwandiswa kunye nomsantsa wokujika, iinkcukacha ezahlukeneyo kunye neemodeli zee-pad, ukuhlangabezana neemfuno zeklinikhi. Inkqubo yokudibanisa idolo iyonke: i-femoral ankle prosthesis anterior malleolus elevation angle ye-5 degrees ukunqanda i-notch; i-inter-ankle fossa ingaphambili ukunciphisa i-osteotomy, i-femoral ankle patella chute ihambela ngaphandle kwaye inzulu, i-patella ayilula ukuyisusa, i-tibial pad ithatha ikhasethi kwaye isikrufu sitshixiwe kabini, umphezulu woqhagamshelwano lwetreyi ye-tibial ucoliwe kakhulu, kwaye isiphatho sephiko setreyi ye-tibial siqinisekisa uzinzo lwenkqubo yokunyanga isamente.

Ukwenza idolo lilungelelaniswe ngendlela yalo kufuneka unikezele ngeenkcukacha ezipheleleyo, ezifana neefilimu ze-CT, imifanekiso ye-MRI kunye nolunye ulwazi, ukuze sikwazi ukwenza ngokwezifiso iimveliso ezichanekileyo nezifanelekileyo kuwe.
