Iimpawu eziphambili zePedicle Fixation
Ukungazinzi komqolo okubuhlungu okukhoyo: i-post-laminectomy spondylolisthesis.ipseudoarthrosis ebuhlungu.
Ukungazinzi okunokwenzeka: i-spinal stenosis.i-degenerative scoliosis.
Ukuqhekeka okungazinzanga.
Ukwandiswa kwe-trut yangaphambili: ithumba.usulelo.
Ukuzinzisa i-osteotomies yomqolo.
Izinto eziluncedo kwiPedicle Screw Fixation
I-pedicle iphinda imele indawo eyomeleleyo yokunamathisela umqolo kwaye ngoko ke amandla abalulekileyo angasetyenziswa kumqolo ngaphandle kokungaphumeleli kwe-bone-metal junction.
I-Pedicle screw fixation okwangoku yenye yezona ndlela zisetyenziswa kakhulu kwi-thoracic yangaphakathi kunye ne-lumbar spine stabilization.Nangona ukulungiswa kwecandelo kunye neengcingo, iibhendi kunye neekhonkco zisadlala indima ebalulekileyo, inzuzo ye-biomechanical ye-screw ye-pedicle yakhokelela ekwandeni kokusetyenziswa kwe-pedicle screw fixation ngokuhamba kwexesha.Ngaphandle koko, izikrufu ze-pedicle zibonelela ngeziphumo eziphezulu zeklinikhi xa kuthelekiswa nezinye iindlela zesixhobo somnqonqo.Nangona kunjalo, kumathambo e-osteoporotic "in vitro" okufanayo okuphambili kunye nexesha elide uzinzo lwabonwa phakathi kwezikrufu ze-pedicle kunye nenkqubo ye-laminar hook eyongeziweyo egxininiswe kwi-lamina kunye ne-perforating screw kunye nezikrufu ze-cortical zibonakaliswe ukuba zinamandla alinganayo okutsala kwithambo le-osteoporotic. xa kuthelekiswa nezikrufu ze-pedicle.
Isalathiso sokusetyenziswa
Uyilo lwesiphelo esibuthuntu, Ukuthintela umsonto wokugxadazela, ukufakelwa lula.
I-multi-axial screw ye-universal direction + -18 °, Ukunciphisa impembelelo yesikhonkwane, ukufakwa kwesakhiwo esiguquguqukayo.
xa i-screw ifakwe, i-fracture igxininiswe kakuhle ngentambo, eya kwandisa ukuzinza kokuphuka.
