kutseka maxillofacial mini rectangle mbale

Locking mbale ndi chipangizo chomangirira chothyoka chokhala ndi bowo lotsekera. Chotsekera mbale chimathandiza fupa kuti ligwirizane kwambiri ndi mbale, kupangitsa kuti nthambi yodulidwayo ikhale yolimba ikayikanso.

Mimba yotsekera idagwiritsidwa ntchito koyamba zaka 20 zapitazo mu opaleshoni ya msana ndi maxillofacial kuti akhazikitse fractures ndikuchepetsa kufalikira kwa minofu yofewa komanso kuvulala.

Chotsekera mbale ndi chipangizo chomangira chophwanyika chokhala ndi zibowo zopindika momwe mbaleyo imagwira ntchito ngati chipangizo cholumikizira ngongole ikalowetsedwa kotiyo yokhala ndi mutu wopindika. Mabowo onse okhoma komanso osatseka atha kuperekedwa kuti alowetsemo misala yosiyanasiyana. Mbale iliyonse yomwe imatha kupindidwa kukhala skrubu yokhazikika (yokhazikika) Sikofi kapena bawuti ndiyomwe imapangitsa kuti mbaleyo ikhale yokhoma. kwathunthu zimadalira dongosolo lokhoma la mbale zitsulo palokha. Kusiyana kwina kungasiyidwe pakati pa mbale yachitsulo ndi fupa pamwamba, zomwe zimathetsa zotsatira zoipa za kukhudzana kolemera pakati pa mbale yachitsulo ndi fupa, komanso kumapangitsa kuti magazi asamayende bwino komanso kukula ndi kuchira kwa periosteum. Kusiyana kwakukulu kwa biomechanical pakati pa mbale yachitsulo ndi mbale yachitsulo ndi yakuti yotsirizirayi imadalira mphamvu ya fupa la fupa.

The locking screw ndi self-tapping screw ndipo ingagwiritsidwe ntchito popanda kugogoda kapena kubowola fupa. Palibe kukakamiza pakati pa mbale yachitsulo ndi fupa la fupa, kotero palibe kupanikizika pa periosteum, kuti muteteze magazi a periosteum. Pankhani ya opaleshoni ya opaleshoni, imatha kukwaniritsa zofunikira za opaleshoni yochepa, ndipo imatha kuteteza magazi a m'deralo, kotero kuti kupasuka kwapakati sikufunika. scaffold ndi zotanuka. Pamaso pa katundu, pali kukondoweza kupsinjika pakati pa midadada yosweka, yomwe imathandizira kupanga ma callus ndi machiritso a fracture.

Pambuyo maxillofacial fracture, makamaka kuchepetsa ndi fixation.Chizindikiro chofunikira cha kuchepetsa nsagwada kuthyoka ndi kubwezeretsa yachibadwa occlusal ubale chapamwamba ndi m'munsi mano, ndiko kuti, kukhudzana kwambiri ubale teeth.Otherwise izo zidzakhudza kuchira mastication ntchito pambuyo fracture kuchira.Pali njira zitatu wamba Bwezerani:

1.Kuchepetsa kwachangu: kumayambiriro kwa kuphulika kwa nsagwada, gawo la fracture limakhala logwira ntchito, ndipo gawo la fracture losamutsidwa likhoza kubwezeretsedwa ku malo abwino ndi dzanja.

2. Kuchepetsa kuchepetsa: pambuyo pa kuthyoka kwa nsagwada, patapita nthawi yaitali (kuposa milungu itatu ya maxilla, masabata oposa anayi a mandible), kupasuka kuli ndi gawo la machiritso a minofu ya fibrous, kuchepetsa kuchepa kwapamanja sikuli bwino, njira yochepetsera mphamvu ingagwiritsidwe ntchito. Chipilala chopindika, ndiyeno pakati pa chipilala cha mano ndi maxillary, ndi gulu laling'ono la mphira la zotanuka, kotero kuti pang'onopang'ono kubwezeretsanso chiyanjano cha occlusal. Pambuyo pa kuphulika kwa maxillary, ngati gawo la fracture likusintha cham'mbuyo, chigoba cha mano chikhoza kuikidwa pamutu wa maxillary chojambula ndi pulasitiki. The zotanuka traction akhoza kupangidwa pakati pa mano arch splint ndi zitsulo bulaketi, kotero kuti maxillary fracture gawo akhoza kubwezeretsedwa patsogolo.Horizontal yokoka traction ingagwiritsidwenso ntchito pamene mphamvu yaikulu yokoka ikufunika.

3.Kuchepetsa kutseguka: Zizindikiro zochepetsera zotseguka ndi zazikulu.Kuchepetsa kotseguka kuyenera kuchitidwa pamene gawo la fracture likuchotsedwa kwa nthawi yaitali ndipo pali machiritso a fibrous kapena bony malalignment machiritso, ndipo kuchepetsa sikungatheke mwa kugwiritsira ntchito kapena kugwedeza. kugawanikanso kuti abwerere ku malo ake.
