A method and a device for external fixation of bone fracture fixation needles includes implanting a porous substrate, which has a loose texture, softness, uneven consistency and is easy to be penetrated through by a fixation needle, among a plurality of fixation needles exposed outside of the skin of a patient, and then injecting and applying a solidifying agent to the porous substrate or allowing the porous substrate to absorb the solidifying agent, so that the porous substrate is solidified along with the solidification of the solidifying agent to fix the relative position of each of the fixation needles, thereby providing the fractured part of the fracture a good fixation effect.一種骨折固定針的外固定方法及裝置，是在患者露出皮膚外的多數固定針間置入組織鬆散、柔軟、緻密度不等或可被固定針輕易穿過的多孔性底材，再將凝固劑注入、塗於該多孔性底材或讓多孔性底材吸附該凝固劑，使該多孔性底材隨凝固劑凝固而硬化，以固定各該固定針的相對位置，使骨折患部獲得良好固定效果。
