    摘要： An apparatus for inserting an intervertebral prosthesis within a spine of a mammal includes: a handle disposed at a proximal end of the tool and including a drive nut operating to produce rotational torque in response to user-input about a central axis; a first drive shaft including proximal and distal ends; the proximal end in communication with the drive nut, receiving rotational torque therefrom, and imparting rotational torque to the first drive shaft about a first axis, which is laterally offset from the central axis; and the distal end of the first drive shaft including a first drive head; and a chuck disposed at a distal end of the tool and being sized and shaped to engage the intervertebral prosthesis during implantation, wherein the first drive shaft extends through the chuck and the first drive head engages a first gear of the intervertebral prosthesis, such that rotation of the first gear causes rotation and deployment of a first anchoring element of the intervertebral prosthesis.

    摘要： An expandable spinal implant comprising a cage body including at least two movable branches having first end portions that are interconnected to one another and second end portions that are movable relative to one another. The movable branches include a first shell portion having a first pair of longitudinal edges and defining a first hollow region therebetween, and a second shell portion having a second pair of longitudinal edges and defining a second hollow region therebetween, with the first and second hollow regions cooperating to define at least a portion of a hollow interior of the cage body. An expansion member co-acts with the first and second shell portions to transition the cage body to an expanded configuration as the expansion member is axially displaced along said first and second pairs of longitudinal edges. In one embodiment, at least one of the shell portions defines a plurality of retention elements positioned at select axial locations along a corresponding one of the longitudinal edges, with the expansion member engaged with one or more of the retention elements to retain the expansion member at a select axial position to maintain the implant in the expanded configuration.

    摘要： A milling instrument assembly (15) is provided for vertebral endplate preparation along a cutting path obliquely oriented to the axis of approach to the vertebra. The milling instrument assembly (15) provides control of the anterior-posterior depth of endplate removal by guiding cutting assembly (120) in the disc space as it moves transversely across a housing assembly (16.) Methods and techniques are included for using the milling instrument assembly (15) in spinal surgery.
