I-Orthopedic titanium knee replacement joint prosthesis
I-Orthopedic titanium knee replacement joint prosthesis
Idolo lelona lungu likhulu emzimbeni womntu. Lidibanisa i-femur yakho ne-tibia yakho. Likunceda ume, ushukume kwaye ugcine ibhalansi yakho. Idolo lakho likwane-cartilage, efana ne-meniscus, kunye ne-ligaments, kubandakanya i-anterior cruciate ligament, i-middle cruciate ligament, i-anterior cruciate ligament, kunye ne-anterior cruciate ligament.
Kutheni sifunaukutshintshwa kwedolo?
Esona sizathu siqhelekileyoutyando lokutshintsha idolokukunciphisa iintlungu ezibangelwa yi-arthritis. Abantu abafuna utyando lokutshintshwa kwamalungu edolo banengxaki yokuhamba, ukunyuka izinyuko kunye nokuvuka ezitulweni. Injongo yokufakelwa kwamalungu edolo kukulungisa umphezulu wendawo eyonakeleyo yedolo kunye nokunciphisa iintlungu zamadolo ezingenakulawulwa zezinye iindlela zonyango. Ukuba yinxalenye yedolo yonzakeleyo kuphela, ugqirha otyandayo unokutshintsha loo nxalenye. Oku kubizwa ngokuba kukutshintshwa kwamadolo okungaphelelanga. Ukuba lonke ilungu lifuna ukutshintshwa, isiphelo sethambo le-femur kunye ne-tibia kuya kufuneka sitshintshwe, kwaye lonke ilungu kuya kufuneka libe ngaphezulu. Oku kubizwa ngokubaukutshintshwa kwedolo elipheleleyo (i-TKA)Ithambo le-femur kunye ne-tibia ziityhubhu eziqinileyo ezineziko elithambileyo ngaphakathi. Isiphelo senxalenye yokwenziwa sifakwa kwinxalenye ethambileyo esembindini wethambo.
Kuphephe ukuxhomekeka kwiimpawu ezintathu
1. Uyilo lweeradiyumu ezininzi lubonelela
inkululeko yokujika kunye nokujikeleza.
2. Uyilo lwe-radius ehlayo ye-J curve femoral condyles lunokuthwala indawo yoqhagamshelwano ngexesha lokujika okuphezulu kwaye luphephe ukumba ngaphakathi.
Uyilo olucekeceke lwePOST-CAM lufezekisa i-osteotomy encinci ye-intercondylar ye-PS prosthesis. I-retained anterior continuous bone bridge inciphisa umngcipheko wokuqhekeka.
Uyilo olufanelekileyo lwe-trochlear groove
I-patellatrajectory eqhelekileyo yi-S shape.
● Nqanda ukuthambekela kwe-patella medial xa ugoba kakhulu, xa idolo kunye ne-patella zinamandla okucheba kakhulu.
● Musa ukuvumela umgca ophakathi wendlela yepatella.
1. Iiwedges ezihambelanayo
2. Udonga olusecaleni oluphakathi kwekhondili olucoliweyo kakhulu luyakuphepha ukukrala emva kokugruzuka.
3. Ibhokisi evulekileyo ye-intercondylar ithintela ukukrala kwe-post top.
Ukugoba i-155 degree kungabakufezekisiwengobuchule obuhle botyando kunye nokuzilolonga okusebenzayo
Iikhowuni zokuprinta ze-3D zokugcwalisa iziphene ezinkulu ze-metaphyseal ngesinyithi esinemingxuma ukuvumela ukukhula.
Iimpawu zokutshintshwa kwamalungu edolo
Irheumatoid arthritis
I-arthritis emva kwe-traumatic, i-osteoarthritis okanye i-arthritis ewohlokayo
Ukungasebenzi kakuhle kwe-osteotomies okanye ukutshintshwa kwe-unicompartmental okanye ukutshintshwa kwedolo elipheleleyo
