Abstract
An interbody distractor and geometry trial instrument to measure a height and an angle for an associated implant includes a height handle and an expansion head coupled to the height handle that is adapted to be positioned in a vertebral body. A wedge sleeve is coupled to the expansion head, to control an angle of a first surface plate and a second surface plate of the expansion head when the wedge sleeve interacts with the expansion head. A wedge sleeve knob is adapted to drive the wedge sleeve linearly towards the vertebral body when the wedge sleeve knob is actuated. A height of the expansion head and an angle of the first and the second surface plate are measured to determine the height and the angle of the associated implant when the height handle and the wedge sleeve knob are actuated.
