Cov lus qhia kho mob
Lub ntsiab lus qhia rau Pedicle Fixation
Kev mob txha caj qaum tsis ruaj khov: post-laminectomy spondylolisthesis.mob pseudoarthrosis.
Muaj peev xwm instability: spinal stenosis.degenerative scoliosis.
Cov pob txha tsis ruaj khov.
Augmenting anterior strut grafting: qog.kab mob.
Stabilizing spinal osteotomies.
Qhov zoo ntawm Pedicle Screw Fixation
Lub pedicle tseem sawv cev rau qhov muaj zog tshaj plaws ntawm kev sib txuas ntawm tus txha nqaj qaum thiab yog li muaj zog tseem ceeb tuaj yeem siv rau tus txha nraub qaum yam tsis muaj kev ua tsis tiav ntawm cov pob txha-hlau hleb.
Pedicle ntsia hlau fixation yog tam sim no ib qho ntawm feem ntau siv modalities rau sab hauv thoracic thiab lumbar qaum stabilization.Txawm hais tias segmental fixation nrog cov xov hlau, bands thiab hooks tseem ua lub luag haujlwm tseem ceeb, biomechanical zoo ntawm pedicle ntsia hlau ua rau muaj kev nce ntawm kev siv pedicle ntsia hlau fixation lub sij hawm.Tsis tas li ntawd, pedicle screws muab cov txiaj ntsig zoo tshaj plaws hauv kev kho mob piv rau lwm txoj hauv kev ntsuas qaum.Txawm li cas los xij, nyob rau hauv cov pob txha osteoporotic "hauv vitro" zoo ib yam li thawj thiab lub sij hawm ntev kev ruaj ntseg tau pom ntawm pedicle screws thiab laminar nuv system ntxiv rau ntawm lub lamina nrog ib tug perforating ntsia hlau nrog rau cortical screws tau pom tias muaj zog sib npaug hauv cov pob txha osteoporotic. piv rau pedicle screws.
Kev taw qhia rau kev siv
Blunt kawg tsim, Los tiv thaiv stagger xov nyob rau hauv, Yooj yim implantation.
Multi-axial ntsia hlau lub universal kev taw qhia + -18 °, kom txo cov ntsia hlau cuam tshuam, yooj yim installation.
Thaum cov ntsia hlau yog implanted, qhov tawg yog zoo compressed los ntawm cov xov, uas yuav ua rau kom lub stability ntawm lub puas.
