Systems and methods for setting an implant are provided. A robotic arm may automatically orient a screw head to a predetermined orientation relative to a pedicle screw. The screw head may be pivotably coupled to the pedicle screw. The robotic arm may lock the screw head in the predetermined position.

A surgical knife for introduction through a cannula includes a handle portion with an angled transition to a reduced portion. A blade connected to the reduced portion has a width perpendicular to the longitudinal axis that is equal to or greater than half the effective handle dimension. The blade is connected to the handle so that the outer transverse edge of the blade is outwardly offset from the outer surface of the handle. The blade width is preferably 80% of the effective dimension of the handle. The blade includes a cutting edge that extends across the width of the blade. In use, the knife can be extended through a cannula to make a first incision, retracted and rotated 180°, and then make another incision colinear with the first incision to create a single incision having a length greater than the width of the cannula.

An orthopedic burring tool includes a burring tip configured for removal of bone to form a bore in the bone, an elongated intermediate segment having a smooth outer surface along a length of the segment, a conical widening segment at the proximal end of the intermediate segment that widens from the diameter of the burring tip to a diameter that is about twice the burring tip diameter. The widening segment includes an outer surface configured for removal of bone upon rotation of the burring tool. The tool includes an upper segment configured for engagement to a rotary driving tool and having a cylindrical outer surface configured for removal of bone upon rotation of the burring tool for removal of material from bony structure adjacent the bone bore formed by the burring tip.
