    摘要: A screw tower that is a single-use instrument that attaches to existing screws but remains open along a rod slot to allow for screws to intermesh and prevent interference of adjacent screws during screw and rod insertion. The screw tower interfaces with existing features of the screws to facilitate screw insertion, rod insertion, rod reduction, and locking cap insertion in a percutaneous approach. The tower is broken in half and removed from patient to end with a completed construct.

    摘要: 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.

    摘要: An implant assembly including an expandable vertebral body replacement implant. Two outer cores disposed on opposing ends of an inner are configured to move away from each other when the inner core is actuated. The implant assembly may include removable endplate configured to engage vertebral bodies as interbody spacer or through a corpectomy. The implant may include a locking mechanism to prevent collapse or movement the implant assembly after implantation. The locking mechanism may be automatically engage after removal of an inserter instrument from the implant assembly.
