Tsananguro yeChigadzirwa
132° CDA
Pedyo nechimiro chechisikigo chemuviri
50° Osteotomy angle
Dzivirira femoral calcar kuti uwane rutsigiro rwakawanda rweproximal
Mutsipa Wakatetepa
Deredza kukanganiswa panguva yechiitiko uye wedzera huwandu hwekufamba
Kuderedzwa kwefudzi reparutivi
Dzivirira trochanter huru uye bvumira kuvhiyiwa kusingakuvadzi zvakanyanya
Deredza saizi yeM/L iri kure
Ipai kubatana kweproximal cortical yeA Shape femur kuti muwedzere kugadzikana kwekutanga
Dhizaini yegroove kumativi ese
Zvinobatsira kuchengetedza mapfupa akawanda uye ropa riri mukati medumbu mumativi eAP emuti wefemoral uye kuwedzera kugadzikana kwekutenderera.
Dhizaini yekona yerutivi rwekumashure ine rectangular
Wedzera kugadzikana kwekudzivirira kutenderera.
Di Yakakombamastal
Zvinobatsira kuisa prosthesis kuburikidza nenzira dzepamberi nepadivi, ukuwo uchidzivirira kushushikana kwedivi
Kuoma kwakanyanyakuti pave nekugadzikana mushure mekuvhiyiwa
Ukobvu hwekufukidza hwakakura uye porosity yakakwirazvinoita kuti mapfupa akure zvakadzika mukati mejira, uye zvakare ave nekugadzikana kwenguva refu.
●Ukobvu hwepedyo hwe500 μm
●60% porosity
●Hurema: Rt 300-600μm
Kugadzirwa kwejoini rehudyu
A chidyarwa chehudyumudziyo wekurapa unoshandiswa kutsiva joini yehudyu yakakuvara kana ine chirwere, kuderedza marwadzo uye kudzorera kufamba. Joini yehudyu ijoini ine bhora nesocket inobatanidza femur (pfupa rechidya) nechiuno, zvichiita kuti pave nekufamba kwakasiyana-siyana. Zvisinei, mamiriro akadai se osteoarthritis, rheumatoid arthritis, kutyoka kana avascular necrosis zvinogona kukonzera kuti joini iome zvakanyanya, zvichikonzera kurwadziwa kusingaperi uye kufamba kushoma. Muzviitiko izvi, chiuno chinogona kukurudzirwa.
Kubva muna 2012-2018, kune nyaya 1,525,435 dzekutanga nedzekudzokororakutsiva majoini ehudyu nebvi, pakati pawo ibvi rekutanga rinoita 54.5%, uye chiuno chekutanga chinotora 32.7%.
Mushure mekutsiva majoini, mwero wekupararira kwekutyoka kwepamuviri:
THA Yekutanga: 0.1~18%, yakakwira mushure mekudzokorora
TKA Yekutanga: 0.3~5.5%, 30% mushure mekudzokorora
Kune mhando mbiri huru dzezvinoiswa muhudyu: kutsiva hudyu zvachoseuyekutsiva chikamu chehudyu. Akutsiva hudyu zvachoseKutsiva acetabulum (socket) nemusoro wefemoral (bhora), nepo chikamu chechidya chinotsiva chiuno chinowanzo tsiva musoro wefemoral chete. Sarudzo pakati pezviviri izvi inoenderana nehukuru hwekukuvara uye zvinodiwa nemurwere. Kupora mushure mekuvhiyiwa kwechiuno kunosiyana, asi varwere vazhinji vanogona kutanga kurapwa kwemuviri nguva pfupi mushure mekuvhiyiwa kusimbisa tsandanyama dzakatenderedza uye kuvandudza kufamba. Nekufambira mberi muhunyanzvi hwekuvhiya uye tekinoroji yeimplant, vanhu vazhinji vanoona kuvandudzwa kukuru muhupenyu hwavo mushure mekuvhiyiwa kwechiuno, zvichivabvumira kudzokera kumabasa avo avanofarira nesimba idzva.
