Distal tibial fractures yog ib hom kab mob qis qis. Kev kho mob ib txwm muaj xws li Locking plates thiab antegrade intramedullary rau tes txhua tus muaj lawv qhov tsis zoo. Locking plates tej zaum yuav ua rau muaj kab mob tom qab phais lossis cov nqaij mos necrosis, ua rau lub sijhawm rov qab los; Txawm hais tias cov ntsia hlau antegrade muaj qhov cuam tshuam tsawg heev, lawv tuaj yeem ua rau lub hauv caug sib koom ua ke, ua rau mob, thiab ua rau muaj kev pheej hmoo ntawm kev kho tsis zoo lossis tsis zoo, cuam tshuam kev rov qab los.
2Kev daws teeb meem tshiab: Distal Tibial Nail (DTN)
Ib qho kev xaiv kho tshiab-Distal Tibial Nail (DTN) - muab qhov kev xav tshiab rau kev tswj cov pob txha pob txha pob txha nrog nws cov qauv retrograde tshwj xeeb.
Daim duab 1: DTN retrograde insertion tsim
II. Kev phais mob
1Tus neeg mob qhov chaw thiab kev npaj txo qis
Tus neeg mob muab tso rau hauv lub supine txoj hauj lwm. Tshem tawm cov pob txha tawg yuav tsum tau txo qis manually; yog tias tsim nyog, siv qhov txo qis los pab ua ntej tso DTN. Yog tias muaj qhov sib txuam nrog cov pob txha pob txha, kev kho kom zoo ntawm cov nqaij mos tuaj yeem pab txo tibial.
Cov ntsiab lus tseem ceeb: Supine txoj hauj lwm, siv txo forceps yog tias xav tau. Ua ntej kev tswj fibular pob txha kom ntseeg tau tias tibial txo qis.
2DTN insertion txheej txheem
Ib tug 2-3 cm ntev incision yog ua nyob rau hauv lub ntsis ntawm lub medial malleolus kom nthuav tawm lub sab deltoid ligament. Ib daim ntawv qhia tus pin yog muab tso rau ntawm los yog me ntsis nruab nrab mus rau lub ntsis ntawm lub malleolus, 4-5 mm los ntawm articular nto.
Post-op: Tsuas yog 6 me me incisions, ua tiav kho tsis pub dhau 1 xyoos
Cov ntsiab lus kho mob
DTN implanted los ntawm me me incisions nrog zoo heev mos mos preservation. Fibular puas stabilized nrog intramedullary ntsia thawv. Tus neeg mob tau txais kev rov zoo tag nrho tsis muaj teeb meem.

VI. Kev sib tham
1Biomechanical Stability
Retrograde rau tes muaj superior axial thiab rotational nruj piv rau medial Locking plates thiab antegrade rau tes. Greenfield et al. Kev sim biomechanical qhia tau hais tias siv ob lub qhov ntsia hlau distal hauv DTN ua tiav 60-70% ntawm cov compressive txhav thiab 90% ntawm qhov torsional nruj piv rau peb cov ntsia hlau.
2Qhov zoo ntawm DTN
Piv rau Locking plates , intramedullary rau tes ua rau cov nqaij mos puas tsawg, tshwj xeeb tshaj yog tsim rau cov neeg laus thiab cov neeg uas muaj cov nqaij mos raug mob hnyav los ntawm kev raug mob siab. Cov txheej txheem tsis tas yuav tsum tau lub hauv caug flexion, txo qhov kev pheej hmoo ntawm kev txo qis thiab ua kom haum rau cov neeg mob uas muaj kev txwv lub hauv caug.
