A revision instrument for positioning and securing an intervertebral implant in an intervertebral space between vertebrae is provided. The revision instrument includes a shaft having a body extending from a first end to a second end. A first port and a second port extend through the body of the shaft and a connection tool having a first end and second end is positioned within the first port. The connection tool extends through the first end of the shaft through the second end of the shaft. The first end of the connection tool includes a mating feature configured to couple with an expandable implant and the second end of the connection tool includes a rotation feature configured to rotate the connection tool to engage or disengage the connection tool with the expandable implant. The second port is configured to receive an expansion driver for expanding or compressing the expandable implant.

Systems and methods for performing spinal surgery

A detachable vertical cutter for insertion into a cylinder or tube is formed as a single unitary structure. The single blade has a pair of tool attachment end portions and a cutting blade extending in a loop between the attachment ends. The cutting blade is inclined vertically relative to a longitudinal axis of a cylinder or tube into which the attachment ends can slide into. The cutting blade has a cutting edge, a portion of which when extended free of the cylinder or tube will extend a distance greater than the tube outside diameter. The cutting edge when pushed inwardly and pulled outwardly between adjacent vertebrae scrapes and cuts disc material. When retracted the cutting blade deflects into the cylinder or tube for insertion or extraction into or from the disc space.

Vertical cutter and method of use

A bone anchor locking device for receiving a bone anchor having a shank and an enlarged head, the device has a bone anchor, a dome and a conical split washer. The receiving portion has a base extending radially outward and inwardly to a wall. The dome has a center aperture sized to pass a bone anchor. The split washer has an inner conical surface sloped to slide and expand against at least a portion of the base on insertion of a bone anchor to allow a maximum diameter of a head of a bone anchor to pass and thereafter the split washer retracts overlying the maximum diameter of the head to prevent a bone anchor from backing out.

A spinal implant revision device has a revision connector and a tulip member. The revision connector is configured for attachment to a pre-existing rod in a patient. The revision connector has a slotted opening configured to receive a first or a pre-existing rod. The tulip member is pivotally connected to the revision connector and movable in angularity within predetermined ranges in a first plane. This first plane is parallel to a rod to which the revision connector is attached. A second plane which is non-parallel to that first plane allows a second or new rod to be received in the tulip and allows the second rod to pivot relative to the first rod.

A dilator delivered nerve shield assembly is presented. The dilator delivered nerve shield assembly has an elongate dilator shaft with a distal end and a proximal end. The dilator delivered nerve shield assembly also has an elongate nerve shield that is configured for simultaneous insertion with the elongate dilator shaft.

An instrument for selectively decorticating a bony surface is described. The instrument may have a decorticating implement having a truncated scoop on its medial face and an inclined blade disposed on its opposing lateral face. The blade edge may be coincident with the linear distal edge of the truncated scoop. Also described is a method for using such an instrument to selectively decorticate a bony surface in order to prepare it for service as a bone graft bed.

Decorticating surgical instruments and guidance systems with tactile feedback

An improved spinal fusion system () for positioning between a first and second vertebral body, the system () has a body (), a pair of polyaxial fasteners () and a locking bridge (). The distal end has a slotted opening () extending through the body () and forming a gap extending between the two or more bore holes () to form a deflectable bridge () spanning the bore holes (). The bridge () has a center opening () for receiving a set screw () passing through the bridge () into a threaded opening () in the body. When the set screw () is tightened, it deflects the bridge () closing the gap as the bridge () contacts an exterior surface of each head () of the polyaxial fasteners (). The angulation of each polyaxial screw () is adjustable, controlled by the tightening of the set screw. Initial contact of the bridge () with the head () of the fastener () reduces angulation movement of the shank () requiring manual manipulation. Increased tightening of the set screw () fixes the angulation as the bridge () reduces the gap and increases fastener head contact forces.
