Abstract: Systems, apparatuses and methods for bone fusion are disclosed. In particular, a fixation screw assembly is provided that comprises a bone engagement portion including a shaft and a head member. The assembly also includes a flexible washer member that can be operably attached and secured around the head member of the bone engagement portion.

The superior core may be connected to the inferior core, and the inferior core may be connected to the inferior endplate. The inferior core may be made from a flexible material that may enable the artificial disc to expand or compress vertically.

Abstract: A surgical navigation system is provided to create a plan to correct a deformed spinal alignment.

Abstract: A power tool for removing an intervertebral disc and preparing vertebral endplates is described. The power tool may include a cutting element, and the height of the cutting element may be adjustable. The cutting element may be a braided cable and may include one or more beads to enhance the effectiveness of the cable. The cutting element may have a minimum height requirement, which may not be satisfied in patients with a collapsed disc due to degenerative disc disorder. For these patients, also described are bone tamps for increasing the intervertebral distance and providing access to tissues distal to the tamp. One type of bone tamp features an inflatable balloon with an inner lumen. Another type of bone tamp includes an expanding distal end and an inner cannula. Also described is a manual expander scraper tool that is compatible with both types of bone tamp.

Abstract: A spacer for separating bones of a joint includes a frame and a carriage. The carriage has ramped surfaces, and is slideably moveable in relation to the frame. A screw support is moveably connected to the frame to form a changeable angular orientation with respect to the frame. An actuating screw is supported by the screw support, and is connected to the carriage to cause the carriage to slideably move in relation to the frame when the actuating screw is rotated. Opposing endplates are configured to engage opposing bone of the joint, and each has ramped surfaces mateable with the ramped surfaces of the carriage. When the carriage is moved by rotation of the actuating screw, the ramped surfaces of the carriage and the endplates slide against each other, causing the endplates to move relatively apart, to increase the height of the spacer.

Abstract: Devices, systems, and methods for automatically exchanging a first end-effector on a robot arm with a second end-effector housed in a docking station. The first end-effector has a clamp that either engages or disengages the robot arm based upon an application of force of the robot arm onto the end-effector. The clamp has a spring loaded clip that disengages the first end-effector to allow the robot arm to move away from the released first end-effector. The robot arm is configured to automatically move to a port of a docking station housing the desired second end-effector using magnetic coils on the robot arm and the docking station to guide the robot arm.

Abstract: Spinal plates with additional features to improve the stability of the interface between the plate and the underlying bone. A bone plate may include one or more sharp ridges along the periphery of its underside. When attached to bone, the ridge digs into the bone and increases stability. A bone plate may alternatively or additionally include one or more holes for optional spikes, which may be inserted once the plate is attached to the bone. By separating the spikes and including them as an optional component, the plate may enhance stability while reducing or eliminating the chance of the spike injuring the patient. Furthermore, bone screws may incorporate alternating notches and ridges into the head of the screw. The notches and ridges may interface with a set screw, thereby preventing rotation and loosening of the screw.
