Abstract: A spinal surgery navigation system is disclosed for computer assisted navigation during spinal surgery. The spinal surgery navigation system is operative to obtain intra-operative feedback data and/or post-operative feedback data regarding spinal surgery outcome for a plurality of patients, and train a machine learning model based on the intra-operative feedback data and/or the post-operative feedback data. The operations obtain pre-operative patient data characterizing a spine of a defined-patient, generate a spinal surgery plan for the defined-patient based on processing the pre-operative patient data through the machine learning model, and provide the spinal surgery plan to a display device for review by a user.

Abstract: A joint spacer therapeutically maintains separation of bones of a joint. A carriage is slideably retained within the frame and has at least one ramped surface. An actuator screw is threadably engaged with the frame, and rotatably connected to the carriage, to cause the carriage to slideably move within the frame when the actuator screw is rotated. First and second endplates engage the bones of the joint, and each has at least one ramped surface that is mateable with the ramped surface of the carriage, whereby when the carriage is slideably moved by rotation of the actuator screw, the endplates ramped surface slides against the carriage ramped surface to cause the endplates to move along an axis transverse to the longitudinal axis of the frame, to increase the height of the spacer. Piercing elements are connected to the carriage to pierce bone of the joint when the carriage is moved.
