Abstract
Apparatus and methods for spinal surgery include a retractor with an elongated body extending along a longitudinal axis between a distal end and an opposite proximal end. The retractor defines a passage between the distal and proximal ends and a window opening into the passage adjacent to the distal end. The apparatus also includes a guide member extending laterally from the proximal end of the retractor and the guide member includes a body extending along an arc. The body defines a number of trajectories each intersecting the window of the retractor. The apparatus further includes an instrument removably mounted to the guide member and the instrument is movable along the guide member and securable to the guide member in any one of the number of trajectories so that the instrument can be moved along the selected trajectory through the window.
