Kutengeswa kunopisa Ti alloy JDS yakazara hudyu inotsiva titanium joint prosthesis

A kudyara hudyuchigadzirwa chekurapa chinoshandiswa kutsiva chakakanganisika kana chirwere chehudyu joint, kubvisa marwadzo uye kudzorera kufamba. Kubatana kwehudyu ibhora uye socket joint inobatanidza femur (chidya chepfu) kune pelvis, ichibvumira kufamba kwakasiyana-siyana. Nekudaro, mamiriro akadai seosteoarthritis, rheumatoid arthritis, fractures kana avascular necrosis inogona kuita kuti mubatanidzwa udzikire zvakanyanya, zvichikonzera kurwadziwa kusingaperi uye kufamba kushoma. Muzviitiko izvi, kuiswa kwehudyu kunogona kukurudzirwa.

Kubva 2012-2018, pane 1,525,435 nyaya dzepuraimari nekudzokorora.hudyu nemabvi majoini kutsiva, pakati peiyo mabvi ekutanga anotora 54.5%, uye hip yekutanga inotora 32.7%.

Mushure mekubatana kutsiva, chiyero chechiitiko chekuputsika kweperiprosthetic:
Primary THA: 0.1 ~ 18%, yakakwirira mushure mekudzokorora
Primary TKA: 0.3 ~ 5.5%, 30% mushure mekudzokorora

Kune mhando mbiri huru dzekudyara hudyu: zvachose hudyu kutsivauyechikamu chehudyu chinotsiva. Azvachose hudyu kutsivakunosanganisira kutsiva zvese acetabulum (socket) uye musoro wechikadzi (bhora), nepo kutsiva hudyu kunowanzo kutsiva chete musoro wechikadzi. Chisarudzo pakati pezviviri zvinoenderana nekuwanda kwekukuvara uye zvinodiwa nemurwere. Kupora mushure mekuvhiyiwa kwehudyu kuisirwa kunosiyana, asi varwere vazhinji vanogona kutanga kurapwa kwemuviri nguva pfupi mushure mekuvhiyiwa kusimbisa mhasuru dzakatenderedza uye kuvandudza kufamba. Nekufambira mberi kwehunyanzvi hwekuvhiya uye tekinoroji yekudyara, vanhu vazhinji vanowana kuvandudzwa kukuru kwehupenyu hwavo mushure mekuvhiyiwa kwehudyu kuisirwa, zvichivabvumira kudzokera kumabasa avo avanofarira nesimba idzva.
