Sei tichishandisasikuruu yepediclekana musana wakatyoka?
Muzongoza wepazasi, sechimiro chepasi chemuzongoza wemunhu, chinova ndicho chikamu chikuru chehudyu, chinotsigira huremu hwese hwemuviri wepamusoro.Zvisinei, musana we lumbar unogona "kusagadzikana" nekuda kwezvikonzero zvakasiyana-siyana. Mienzaniso inosanganisira kutyoka kwe lumbar, spondylolysis kana degenerative lumbar spondylolisthesis, degenerative lumbar scoliosis, lumbar disc herniation ne vertebral endplate inflammation, osteophytes dzakaita semuromo wakavhurika pamucheto we vertebrae we anterior ne posterior, hypertrophy yakanyanya ye posterior articular processes, uye iatrogenic bone destruction. Muzviitiko izvi, vertebral sequence ye lumbar spine inogona kukanganiswa kana kutotenderedzwa uye kusuduruka, zvichikonzera kusagadzikana uye kurwadziwa kwemusana kwakaderera muvarwere. Nokudaro, kana lumbar spine iine mamiriro ezvinhu "asina kugadzikana" ataurwa pamusoro apa uye kurapwa kwekuchengetedza kukakundikana, "screw fixation" inodiwa kuchengetedza nekusimudzira kugadzikana kwe lumbar.
Ndeapi mavara edu? Sisitimu Yekusimudza Mapedhi Emusana?
Yedukutendererapediclesikuruuzvigadzirwa zviripo mumatanho matanhatu akasiyana edhayamita, anosanganisira φ4.5mm, φ5.0mm, φ5.5mm, φ6.0mm, φ6.5mm, uye φ7.0mm.
Kugadzirwa kweshinda mbiri dzemapfupa e cortical ne cancellous zvakateerana, kunosimudzira kutenga screws, izvo zvinoenderana nemamiriro emapfupa akafara evarwere. Kuzvibata-bata screw tip kunoita kuti kuisa screw kuve nyore.
Sikuruu dzinoshandiswa pakugadzirisa tambo dzinodzivirira kukuvara kweshinda nekuda kwekushanda nesimba zvakanyanya.
Tambo yekona yakatenderedzwa inodzivirira screw kudzokera shure.
Kugadzirwa kweshinda ine makona akapinza kunodzivirira kupatsanurwa kweshinda.
Chinongedzo cheBuckle Type Crosslink, mafambiro e35° kuti zvive nyore uye zvinochinjika kushanda.
Ndezvipi zvinhu zvikuru zvehurongwa hwetsoka dzemusana?
Ansisitimu yekugadzirisa musana wemukatiine sikuruu, sikuruu yakagadzikwa, tsvimbo yekubatanidza, uye crosslink. Pedcle chimiro chemapfupa chiri padivi rekumashure remusana wemusana, chine simba rakasimba uye kugadzikana. Nekuisa pedicle screw mupedicle, simba remapfupa epedicle rinoshandiswa kupa kugadzikana kwakasimba, zvichigadzira mamiriro akanaka ekupora nekupora kwemusana.
Ndezvipi zvinhu zvakagadzirwa ne spine pedicle system?
Yedusikuruu yemusana nepakeji isina utachiona kuderedza mwero wekukura kwemapfupa, zvinokurumidzisa kubatana kwemapfupa uye kupfupisa nguva yekuvandudza mapfupa.
