Abstract: A curette including a cylindrical handle, having a longitudinal axis, and a shaft, having a longitudinal axis. The shaft is attached to the cylindrical handle at a first end of the shaft, such that the longitudinal axis of the shaft is parallel to, but not collinear with, the longitudinal axis of the cylindrical handle. A tip is included in a second end of the shaft.

Abstract: An anterior fixation device comprises an oval shaped intervertebral spacer and a retaining plate. The spacer has a side wall and superior and inferior walls. The superior and inferior walls are dome-shaped and porous to allow bone to grow through the device to achieve fusion of two adjacent vertebral bodies. Extending from the anterior side of the spacer are superior and inferior lips through which bone screws 16 extend. The bone screws are non-weight bearing and screw into the strongest areas of bone within the vertebral bodies. The intervertebral spacer is hollow inside to allow for bone grafts, bone morphogenic protein, or other bone stimulating substances to be inserted therein. The retaining plate is attachable to the anterior surface of the spacer to prevent the bone screws from backing out once the device is installed.

Abstract translation: 前固定装置包括椭圆形椎间隔垫和保持板。 间隔件具有侧壁和上下壁。 上下壁是圆顶形和多孔的，允许骨通过该装置生长以实现两个相邻的椎体的融合。 从间隔物的前侧延伸的是骨螺钉16延伸的上下唇。 骨螺钉是非重量的，并且被拧入椎体内最坚固的骨骼区域。 椎间隔垫在内部是中空的，以允许将骨移植物，骨形态发生蛋白质或其它刺激物质插入其中。 固定板可安装在间隔件的前表面上，以防止在安装设备后骨螺钉脱离。

Abstract: A bone shaver comprises a top plate with a fixed handle fixedly attached to the top plate and a bottom plate slidably attached to the top plate. The top plate further comprises an anvil at its end. The bottom plate comprises a foot plate and a cutting edge on the foot plate. A movable handle is attached to the bottom plate. Movement of the movable handle towards the fixed handle results in movement of the bottom plate towards the top plate. A cutting edge is provided on the foot plate to thereby cut tissue when the handles are squeezed together.
