Kumvetsetsa kwa Screw ya Spine Pedicle

Chifukwa chiyani timagwiritsa ntchitoscrew ya pediclechifukwa cha kusweka kwa msana?
Msana wa m'chiuno, monga kapangidwe ka pansi pa msana wa munthu, womwe ndi gawo lalikulu lonyamula zolemera pa thunthu, lothandizira kulemera konse kwa thupi lapamwamba.Komabe, msana wa lumbar ukhoza kukhala "wosakhazikika" chifukwa cha zifukwa zosiyanasiyana. Zitsanzo zikuphatikizapo kusweka kwa lumbar, spondylolysis kapena degenerative lumbar spondylolisthesis, degenerative lumbar scoliosis, lumbar disc herniation ndi kutupa kwa vertebral endplate, osteophytes ngati pakamwa potseguka m'mphepete mwa vertebrae, hypertrophy yayikulu ya posterior articular processes, ndi kuwonongeka kwa mafupa a iatrogenic. Pazochitikazi, vertebral sequence ya lumbar spine ikhoza kusokonezeka kapena kuzunguliridwa ndikusunthika, zomwe zimapangitsa kuti odwala asamakhazikike bwino komanso azimva kupweteka kwa msana. Chifukwa chake, pamene msana wa lumbar ukuwonetsa "kusakhazikika" komwe kwatchulidwa pamwambapa ndipo chithandizo chodziletsa sichikugwira ntchito, "kukhazikitsa screw" kumafunika kuti kukhalebe ndikuwongolera kukhazikika kwa lumbar.

Kodi anthu athu ndi otani? Dongosolo la Screw la Spine Pedicle?
ZathukuzungulirapediclescrewZogulitsa zimapezeka mu ma specifications asanu ndi limodzi osiyana a mainchesi, kuphatikizapo φ4.5mm, φ5.0mm, φ5.5mm, φ6.0mm, φ6.5mm, ndi φ7.0mm.

Kapangidwe ka ulusi wawiri wa fupa la cortical ndi la cancellous motsatana, kumawonjezera kugula kwa screw, komwe kumagwirizana ndi mkhalidwe wa mafupa a odwala. Nsonga ya screw yodzigwira yokha imapangitsa kuti kuyikako kukhale kosavuta.

Skurufu yosweka imaletsa kuwonongeka kwa ulusi chifukwa cha kugwira ntchito mopitirira muyeso.
Ulusi wopingasa umathandiza kuti screw isabwerere m'mbuyo.
Kapangidwe ka ulusi wopingasa woyambira kamaletsa kupangika kwa ulusi wopingasa.

Buckle Type Crosslink, mtunda wa 35 ° woyenda kuti ntchito ikhale yosavuta komanso yosinthasintha.

Kodi zigawo zazikulu za adongosolo la msana?
Andongosolo lokhazikika msana mkatiLili ndi sikuru, sikuru yokhazikika, ndodo yolumikizira, ndi crosslink. Pedicle ndi kapangidwe ka mafupa komwe kali kumbuyo kwa thupi la msana, komwe kali ndi mphamvu zambiri komanso kokhazikika. Mwa kuyika sikuru ya pedicle mu pedicle, mphamvu ya mafupa a pedicle imagwiritsidwa ntchito kuti ikhale yokhazikika, ndikupanga mikhalidwe yabwino yochiritsira ndi kuchira kwa msana.

Kodi dongosolo la pedicle la msana ndi chiyani?
Zathuscrew ya msana ndi phukusi lopanda poizoni kuti muchepetse kuchuluka kwa kukwera kwa mafupa, zimathandiza kuti mafupa agwirizane bwino komanso kuchepetsa nthawi yochira.
