Bicondylar tibial plateau fracture ndi hyperextension ndi varus (2)

Njira zopangira opaleshoni

Pambuyo pa kulowetsedwa, odwala amathandizidwa ndi chithandizo cha opaleshoni malinga ndi momwe zinthu zilili.Choyamba, chokonzera chakunja chinakhazikitsidwa, ndipo ngati mikhalidwe ya minofu yofewa inaloledwa, inasinthidwa ndi kukonzanso mkati.

Olembawo adafotokozera mwachidule zomwe adakumana nazo ndipo adapeza kuti chinsinsi chochepetsera fracture ndi kuchepetsa kukonza ndikuchepetsa kuphulika kwapambuyo kwa cortical ya tibia poyamba, ndiyeno kuthana ndi kupanikizana kwapang'onopang'ono kwa anterior tibial plateau, kuti abwezeretse ndege ya sagittal. mzere.

Olembawo amalimbikitsa kugwiritsa ntchito njira za proximal tibial anterolateral ndi posteromedial pofuna kuchepetsa fracture ndi kukonza.

Njira ya posterior tibial ingagwiritsidwe ntchito poyera mawonekedwe a kumbuyo kwa tibia ndikuchita kuchepetsa ndi kukonza mbale yothandizira anteromedial panthawi ya opaleshoni.

Kuonjezera apo, kukonzanso kwakanthawi kochepa kwa posterior tibial plateau fractures kungakhale ngati fulcrum kukweza fracture ya anterior ndi kuchepetsa kusamuka kwa fracture panthawi yokonza kusintha kwa sagittal.

Kuchepetsa kwapambuyo kwa fracture kukatsirizidwa, chipangizo chokonzekera kwakanthawi chiyenera kugwiritsidwa ntchito kukonza, monga 1/3 tubular mbale kapena 3.5mm screw kuchokera kumapeto kwa distal anterior mpaka kumapeto kwa proximal end.

Kenaka, bwezeretsani kugwirizanitsa kwa tibial Plateau articular pamwamba ndi ndege ya sagittal.Pa opareshoni, ntchito kuchepetsa chipangizo ndi nsonga yotakata kuchepetsa kupanikizika ndi kupewa aggravation wa fracture comminuted.

Kubwezeretsedwa kwa posterior tibial inclination kunayambika ndi anterior flap spacer kapena osteotome panthawi imodzi (mkuyu 2).Pansi pa mzere wapakatikati, mawaya angapo a Kirschner adayikidwa mofanana kuchokera kutsogolo kupita kumbuyo, ndipo tibial retroversion inabwezeretsedwa mwa kukweza mawaya a Kirschner, kenako ndikukhazikika pa posterior cortex.

A- Fibular mutu autograft;B- Spinal Cage yodzaza fupa cholakwika

X-ray yam'mbali ikuwonetsa kupunduka kwa sagittal, ndipo filimu yowoneka bwino ikuwonetsa mphamvu zochepetsera kuchepetsa kuphulika kwapambuyo kwa tibial mothandizidwa ndi chosokoneza danga.

Potsirizira pake, mbaleyo idagwiritsidwa ntchito kuchepetsa fracture fragment kuti akonze retroversion ya sagittal.Mapeto a proximal lateral tibial plate (kutseka kapena osatseka) ayenera kukhala ofanana ndi articular pamwamba, ndipo mapeto a distal ayenera kukhala kumbuyo pang'ono.Mbaleyo inakonzedwa ku chigawo choyandikira ndi zomangira, ndiyeno mbale ndi chigawo chodutsacho chinachepetsedwa ndikukhazikika pamtengo wa tibial pokonza mbale ya distal, kuti abwezeretse chikhalidwe chachilendo cha tibial posterior.

Kuchepetsa kusweka kukamalizidwa, kukonza kwakanthawi ndi mawaya a Kirschner angagwiritsidwe ntchito.Nthawi zina, kukhazikika kwakanthawi kochepa kumakhala kovuta kuchita popanda kuyambiranso mzere wa mphamvu ndi kumezanitsa (tricortical iliac graft, fibular head graft, etc.)
