【摘要】The utility model discloses a waist interbody fusion cage, this waist interbody fusion cage are the wedge, and cheng suocheng's contained angle is 10~20 between wedge -form upper surface and the lower surface. Upper surface and lower surface are measure -alike rounded rectangle. Two long limit punishment along rounded rectangle do not are equipped with serration. This long limit is parallel with human sagittal face respectively. Distance between upper surface and the lower surface one side minor face is greater than the distance between the opposite side minor face. Respectively by circle arc surface connection between the minor face of both sides. The inside fretwork of part between upper surface and the lower surface, the externally inwards still is equipped with the through -hole of a plurality of rounded rectangle of being on a parallel with minor faces. This waist interbody fusion cage spreads all over the micropore, has three -dimensional micropore network structure. The utility model provides a waist interbody fusion cage can reduce the risk that fuses the ware and subside and shift, helps the recovering of normal lumbosacral angle to probably increase the success rate that fuses.
