    • Instrumentation for treatment of the spine, including an elongate member having a deformable distal end portion at least partially formed of a flexible and preferably elastic material. The distal end portion has an initial configuration for placement adjacent a vertebral body and a deformed configuration defining at least one outwardly extending projection for displacement of at least a portion of the vertebral body. The elongate member preferably comprises a rod member, a sleeve member and an actuator mechanism for imparting relative linear displacement between the rod and sleeve members to effect outward deformation of the distal end portion of the sleeve member. In one embodiment, the instrumentation is used to compact cancellous bone to form a cavity within a vertebral body. In another embodiment, the instrumentation is used to reduce a compression fracture. In yet another embodiment, the instrumentation is used to distract a disc space between adjacent vertebral bodies.
    • 用于治疗脊柱的装置,包括具有至少部分地由柔性和优选弹性材料形成的可变形远端部分的细长构件。 远端部分具有用于邻近椎体放置的初始构型和限定至少一个向外延伸的突起的变形构型,用于移位至少一部分椎体。 细长构件优选地包括杆构件,套筒构件和致动器机构,用于在杆和套筒构件之间施加相对的线性位移以实现套筒构件的远端部分的向外变形。 在一个实施例中,仪器用于压制松质骨以在椎体内形成腔。 在另一个实施例中,仪器用于减少压缩断裂。 在另一个实施例中,仪器用于分散相邻椎体之间的椎间盘空间。
