The present invention provides a fixation device for a femoral stem, comprising: a guide hole inwardly recessed from an outer edge of the femoral stem at least one fixation pawl including a fixation tooth portion and a linkage wedge to be forced into the guide hole of the femoral stem. After the linkage wedge is forced into the guide hole, it will accordingly drive the fixation tooth portion of each fixation pawl out of the femoral stem and punctured or pressed against the medullary cavity wall of a patients femur.一種股骨柄之固定裝置,係包括:一導穴,自該股骨柄之外緣向內凹設者;至少一固定爪,含有一固定齒部者;以及一聯動楔,可迫入於該股骨柄之導穴中,令該聯動楔迫入該導穴中後,係聯動各該固定爪之固定齒部穿出該股骨柄,並刺入或緊抵於患者股骨的髓腔壁。(10)‧‧‧股骨柄(11)‧‧‧導穴(12)‧‧‧導孔(13)‧‧‧導引溝(14)‧‧‧螺孔(20)‧‧‧聯動楔(21)‧‧‧樞軸(22)‧‧‧溝槽(30)‧‧‧固定爪(31)‧‧‧固定齒部(32)‧‧‧聯動端(321)‧‧‧軸孔(40)‧‧‧螺栓(41)‧‧‧螺桿段
