Orthopedic titanium hauv caug sib koom tes hloov prosthesis
Orthopedic titanium hauv caug sib koom tes hloov prosthesis
Lub hauv caug yog qhov sib koom ua ke loj tshaj plaws hauv tib neeg lub cev. Nws txuas koj femur rau koj tibia. Nws pab koj sawv, txav mus thiab ua kom koj qhov sib npaug. Koj lub hauv caug kuj muaj pob txha mos, xws li cov meniscus, thiab ligaments, nrog rau cov ligament anterior cruciate ligament, nruab nrab cruciate ligament, lub anterior cruciate ligament, thiab lub anterior cruciate ligament.
Vim li cas peb xav taulub hauv caug hloov pauv?
Qhov feem ntau yog vim li caslub hauv caug hloov phaisyog los txo qhov mob los ntawm kev mob caj dab. Cov neeg uas xav tau kev phais lub hauv caug hloov pauv muaj teeb meem taug kev, nce ntaiv thiab nce ntawm cov rooj zaum. Lub hom phiaj ntawm lub hauv caug hloov prosthesis yog kho qhov chaw ntawm lub hauv caug puas thiab txo qhov mob hauv caug uas tsis tuaj yeem tswj tau los ntawm lwm yam kev kho mob. Yog tias tsuas yog ib feem ntawm lub hauv caug puas lawm, tus kws phais feem ntau tuaj yeem hloov qhov ntawd. Qhov no yog hu ua ib nrab lub hauv caug hloov. Yog tias tag nrho cov pob qij txha yuav tsum tau hloov, qhov kawg ntawm cov pob txha femur thiab tibia yuav tsum tau hloov kho, thiab tag nrho cov pob qij txha yuav tsum tau surfacing. Qhov no hu uatag nrho lub hauv caug hloov (TKA). Cov pob txha femur thiab tibia yog cov leeg tawv nrog ib qho chaw mos sab hauv. Qhov kawg ntawm cov khoom siv dag zog yog muab tso rau hauv qhov chaw softer hauv nruab nrab ntawm cov pob txha.
Tsis txhob pendency los ntawm peb nta
1.Qhov ntau lub vojvoog tsim muab
s kev ywj pheej ntawm flexion thiab kev sib hloov.
2.Qhov tsim ntawm decrescent radius ntawm J nkhaus femoral condyles tuaj yeem dais qhov chaw sib cuag thaum lub sij hawm siab flexion thiab tsis txhob ntxig excavating.
Cov qauv tsim ntawm POST-CAM ua tiav qhov me me intercondylar osteotomy ntawm PS prosthesis. Cov pob txha anterior txuas ntxiv txuas ntxiv txo qhov kev pheej hmoo ntawm pob txha.
Qhov zoo tshaj plaws trochlear groove tsim
Qhov ib txwm patellatrajectory yog S puab.
● Tiv thaiv patella medial bias thaum lub sij hawm siab flexion, thaum lub hauv caug sib koom tes thiab patella dais lub zog shear feem ntau.
● Tsis txhob pub patella trajectory hla nruab nrab kab.
1.Matchable wedges
2.Lub siab polished intercondylar sab phab ntsa zam tom qab abrasion.
3.Lub thawv qhib intercondylar zam qhov kev puas tsuaj ntawm ncej saum toj.
Flexion 155 degree tuaj yeem ua tauua tiavnrog cov txheej txheem phais zoo thiab kev ua haujlwm zoo
3D luam ntawv cones los sau loj metaphyseal defects nrog porous hlau kom tso cai rau ingrowth.
Knee Joint Replacement Indications
