Abstract: Disclosed herein is a surgical instrument configured for attachment to a surgical device. The surgical instrument includes a distal region having a curved internal surface configured to mate with a curved external surface of the surgical device, a rotational locking feature that limits rotational movement of the instrument with respect to the surgical device, and an axial locking feature that limits axial movement of the blade with respect to the surgical device. Methods of using the surgical instruments include sliding the axial locking feature past a corresponding axial locking feature on the surgical device, locking the axial locking feature to the corresponding axial locking feature on the surgical device (thereby limiting axial movement of the elongated blade with respect to the surgical device), adjusting the position of the surgical device using the surgical instrument, and disengaging the axial locking feature (for example, by using a disengagement instrument).

Abstract: A lateral plate assembly has an elongated lateral plate for attachment to adjacent vertebrae having a first end portion and a second end portion and a pair of apertures for receiving a first and a second bone screw. The pair of apertures includes a first aperture which is an opening positioned in the first end portion for receiving the first bone screw and a second aperture which is a slotted opening to receive the second bone screw. The second end portion of the lateral plate has an open end with channelled internal sides for receiving and holding a moveable washer on top of the slotted opening. The washer is configured to move along a length of the slotted aperture. The moveable washer has an opening for holding a head of the second bone screw. Movement of the washer relative to the slotted opening increases or decreases the distance between locations of the respective screw heads.

Abstract: The bone anchor disclosed herein includes a tulip housing with a distal radially expandable portion, a threaded shank having a proximal ball head, a pressure cap, and a retaining ring that limits radial expansion of the distal radially expandable portion. During assembly, the pressure cap and the proximal ball head through the distal end of the radially expandable portion. The retaining ring is positioned around the distal radially expandable portion of the tulip housing to prevent distal movement of the pressure cap and the proximal ball head. The bone anchors disclosed herein are configured to be inserted without using tapping steps.

Abstract: An improved spinal fusion system (10) for positioning between a first and second vertebral body, the system (10) has a body (100), a pair of polyaxial fasteners (220) and a locking bridge (102). The distal end has a slotted opening (120) extending through the body (100) and forming a gap extending between the two or more bore holes (110) to form a deflectable bridge (102) spanning the bore holes (110). The bridge (102) has a center opening (50) for receiving a set screw (20) passing through the bridge (102) into a threaded opening (52) in the body. When the set screw (20) is tightened, it deflects the bridge (102) closing the gap as the bridge (102) contacts an exterior surface of each head (210) of the polyaxial fasteners (200). The angulation of each polyaxial screw (200) is adjustable, controlled by the tightening of the set screw. Initial contact of the bridge (102) with the head (210) of the fastener (200) reduces angulation movement of the shank (220) requiring manual manipulation.

Abstract: The present invention provides a unique way to provide a self-locking screw opening that has no separate parts. The self-locking feature (20) is formed in the wall (11) of the screw receiver opening (12) and automatically locks a screw (100) from backing out. During insertion of the screw (100) into bone, the screw head (110) passes one or more, preferably two nubs (20) or one or more projections (20) formed into the surface wall (11) of the receiver opening (12), and as the screw (100) is threaded into the bone, the screw head (110) contacts the nubs (20) or projection (20) and the screw (100) is deflected slightly in a direction opposite the nubs (20) or projection (20) allowing the screw head (110) to pass by the nubs (20) or projection (20) locking the screw (100) from backing out.
