Ho hloka botsitso ho teng ha lesapo la mokokotlo: post-laminectomy spondylolisthesis.pseudoarthrosis e bohloko.
Ho se tsitse ho ka bang teng: spinal stenosis.degenerative scoliosis.
Ho robeha ho sa tsitsang.
Ho eketsa strut grafting: hlahala.tšoaetso.
Ho tsitsisa li-osteotomy tsa mokokotlo.
Melemo ea Pedicle Screw Fixation
The pedicle e boetse e emela ntlha e matla ka ho fetisisa ea ho khomarela mokokotlo oa mokokotlo 'me kahoo matla a bohlokoa a ka sebelisoa mokokotlong ntle le ho hlōleha ha lesapo-metal junction.
Pedicle screw fixation hona joale ke e 'ngoe ea mekhoa e sebelisoang ka ho fetisisa bakeng sa ho tsitsisa ka hare ho sefuba le lumbar spine.Le hoja ho lokisa likarolo ka lithapo, lihlopha le lihakisi li ntse li phetha karolo ea bohlokoa, melemo ea biomechanical ea "screw" ea pedicle e entse hore ho be le keketseho ea tšebeliso ea "pedicle screw fixation" ka nako.Ntle ho moo, li-screws tsa pedicle li fana ka liphello tse phahameng tsa kliniki ha li bapisoa le mekhoa e meng ea lisebelisoa tsa mokokotlo.Leha ho le joalo, masapong a osteoporotic "in vitro" botsitso bo tšoanang ba mantlha le ba nako e telele bo ile ba bonoa lipakeng tsa screws tsa pedicle le laminar hook system e kenyellelitsoeng holim'a lamina e nang le screw ea perforating hammoho le li-screws tsa cortical li bonts'itsoe li na le matla a lekanang a ho hula masapong a osteoporotic. ha e bapisoa le li-screw tsa pedicle.
Tataiso bakeng sa tšebeliso
Moralo o sa hlakang, Ho thibela khoele e thekeselang, Ho kengoa habonolo.
Multi-axial screw's universal direction + -18 °, Ho fokotsa tšusumetso ea lipekere, ho kenngoa ha sebopeho sa Flexible.
ha sekoti se kenngoa, ho robeha ho hatelloa hantle ke khoele, e leng ho tla eketsa botsitso ba ho robeha.
