I-PSS 5.5 &6.0 Isistimu Yokulungisa I-Posterior Spinal Inter-Fixation
Isingeniso Somkhiqizo
Iphephile, ilula futhi isebenza kahle kakhulu I-Posterior Pedicle esetshenziselwa ukulungiswa kwangaphakathi komgogodla
Idizayini yentambo ye-engeli engalungile
Ukunciphisa i-torque yokukhiya
Amandla okulungisa amakhulu
Ukusebenza kahle komshini
Izinzuzo Zomkhiqizo
Idizayini yesihlalo sesikulufa sephrofayili ephansi
Ukucasuka kwezicubu ezithambile ezincane
Isifunda esikhulu sokuxhunyelelwa amathambo
Idizayini enezintambo ezimbili
Ukulungiswa okunamandla
Ukukhishwa kwesikulufa esincane
Ukufakwa ngokushesha
Amathiphu Ezokwelapha
Izinkomba Eziyinhloko Zokulungiswa Kwe-Pedicle
Ukungaqini komgogodla okubuhlungu okukhona: i-post-laminectomy spondylolisthesis.i-pseudoarthrosis ebuhlungu.
Ukungazinzi okungenzeka: i-spinal stenosis.i-degenerative scoliosis.
Ukuphuka okungazinzile.
Ukwengeza i-anterior strut grafting: isimila.ukutheleleka.
Ukuzinzisa ama-osteotomies omgogodla.
Izinzuzo ze-Pedicle Screw Fixation
I-pedicle iphinde imele iphuzu eliqine kakhulu lokunamathiselwe komgogodla futhi ngaleyo ndlela amandla abalulekile angasetshenziswa emgogodleni ngaphandle kokwehluleka kwe-bone-metal junction.
Ukulungiswa kwesikulufu se-Pedicle okwamanje kungenye yezindlela ezisetshenziswa kakhulu zokuqiniswa kwe-thoracic yangaphakathi kanye ne-lumbar spine.Nakuba ukulungiswa kwezigaba ngezintambo, amabhande namahhuku kusadlala indima ebalulekile, izinzuzo ze-biomechanical zesikulufu se-pedicle zibangele ukwanda kokusetshenziswa kwe-pedicle screw fixation ngokuhamba kwesikhathi.Ngaphandle kwalokho, izikulufu ze-pedicle zinikeza imiphumela yomtholampilo ephakeme kakhulu uma kuqhathaniswa nezinye izindlela ze-instrumentation yomgogodla.Kodwa-ke, emathanjeni e-osteoporotic "in vitro" ukuqina okufanayo okuyisisekelo nesikhathi eside kwabonwa phakathi kwezikulufu ze-pedicle kanye nesistimu ye-laminar hook ehlanganiswe ngaphezu kwalokho egxilwe ku-lamina ngesikulufa sokubhoboza kanye nezikulufu ze-cortical kuboniswe ukuthi kunamandla alinganayo okudonsa ethanjeni le-osteoporotic. uma kuqhathaniswa nezikulufa ze-pedicle.
Isiqondiso sokusetshenziswa
Idizayini yesiphetho esifiphele, Ukuvikela uchungechunge oluyaluza, ukufakwa kalula.
I-Multi-axial screw's universal direction+ -18°, Ukunciphisa umthelela wezinzipho, ukufakwa kwesakhiwo esivumelanayo.
lapho i-screw ifakwe, ukuphuka kucindezelwe kahle ngentambo, okuzokwandisa ukuzinza kwe-fracture.
