Bone rasp and graft delivery sheath and related methods

Abstract

Surgical systems and methods for preparing multiple vertebra levels for spinal fusion are disclosed herein. An example method can include inserting a delivery sheath through a first incision formed proximate to a first pedicle screw, as well as advancing the delivery sheath toward one or more additional pedicle screws disposed in bone. The method can further include inserting an instrument with a cutting surface into the delivery sheath and passing the instrument over the bone in which the one or more additional pedicle screws are disposed to decorticate the bone with the cutting surface. The method can also include removing the instrument from the sheath, as well as passing at least one of a bone graft or a biologic material through the sheath to deliver the at least one of the bone graft or the biologic material to a surface of the bone exposed by the decorticating of the bone
