"10% yeAnkle Fractures inoperekedzwa neTibiofari Syndissmosis yekukuvara kweSyndendemosis. Maererano neAo bhuku, rinokurudzirwa Isa iyo distal tibiofular screw 2 cm kana 3.5 cm pamusoro peiyo distal tibial articular pamusoro, pakona ye 20-30 ° kusvika kuTibua kune iyo Tibia, ine hukasha munzvimbo isina kwayakarerekera. "
Manual kusawirirana ne distal tibiofibular inowanzoitika mukutsauka mune yekupinda munzvimbo yekupinda uye naiwo, hapana nzira chaiyo yekubvisa nzira yekuisa yeiyi screws. Kuti ugadzirise nyaya iyi, vaongorori vekunze vakatora nzira itsva, iyo 'angle bisector nzira.
Uchishandisa kufungidzira data kubva 16 zvakajairika majoini majoini, 16 3D-anodhindwa mhando dzakagadzirwa. Panzvimbo ye2 cm uye 3.5 cm pamusoro peiyo tibial articular pamusoro, maviri ma1,6 mm Kirschner waires akaenzana neyejogsion akaiswa padhuze nepamhepo yeTibia neTibula, zvichiteerana. Iyo kona iri pakati pemawairi maviri akayerwa uchishandisa protractor, uye ne2,7 mm Drill Mushure mekunge screw kuisirwa, screw yakatemwa nekureba kwayo uchishandisa saw kuti uongorore hukama pakati pechikepe chinotungamira uye chepakati axis yeTibia neTibula.
Miedzo yekufungidzira inoratidza kuti pane kusarudzika kwakanaka pakati peTibia neTibula uye nekona bisector mutsara, pamwe pakati peiyo axis uye iyo screw kutungamira.
Heoretically, iyi nzira inogona kuisa zvinobudirira screw parutivi rwezasi yeTibia neTibula. Nekudaro, panguva yekuvhiya, kuisa iyo Kirschner waya padhuze neyenzidhi uye yepashure medhi yeTibia neTibula inoisa panjodzi yekukuvadza mitsipa yeropa uye nerves. Pamusoro pezvo, nzira iyi haigadzirise nyaya yeIatrogenic kushungurudzika, sezvo iyo Disky Tibiofularlar alignment isingakwanisi kuongororwa zvakakwana intrauperarative isati yaiswa screw.
