Abstract: An orthopedic implant having a titanium or titanium alloy body with a plurality of surfaces. The orthopedic implant is produced according to a process comprising the steps of: (a) additively building the orthopedic implant; and then (b) mechanically, chemically, or mechanically and chemically eroding one or more surfaces of the orthopedic implant to (i) remove alpha case from, and (ii) impart an osteoinducting roughness including micro-scale structures and nano-scale structures into, the one or more surfaces.

Abstract: Bone-contacting surfaces and free surfaces of orthopedic implants. The implants are additively manufactured, followed by mechanical, chemical, or mechanical and chemical erosion. At least some of the surfaces of the implants include an osteoinducting roughness that has micro-scale structures and nano-scale structures that facilitate and enhance osteoinduction and osteogenesis, as well as enhanced alkaline phosphatase, osterix, and osteocalcin expression levels along the pathway of mesenchymal stem cell differentiation to osteoblasts.

Abstract: Implants for vertebral body or functional spinal unit replacement comprise a bioactive surface roughening on one or more of the anterior, posterior, and lateral surfaces of the implant. The bioactive surface includes macro-, micro-, and nano-scale structural features that contact vertebral bone that lines a specialized channel in a vertebrae, and thereby facilitate bone growth and osteointegration of the implant with the vertebral bone.

Abstract: Orthopedic implants produced by additive manufacture, followed by refinement of exterior and interior surfaces trough mechanical erosion, chemical erosion, or a combination of mechanical and chemical erosion. Surface refinement removes debris, and also produces bone-growth enhancing micro-scale and nano-scale structures.

Abstract: A system for use during surgical procedures. The system includes an implant and a tool. The implant combines a modular adjustable cage and a shim that locks the cage into position, after the cage has been adjusted to its final position and at its final height, in situ. The tool combines an expander and an inserter. A related method of using the system is also provided.

Abstract: A system for use during surgical procedures. The system includes an implant and an inserter. The implant has a faceted post that rotates, ribs adapted to receive impact from an instrument to help position the implant, and stops. The inserter has a sleeve, into and from which a hook retracts and extends and on which a tab is disposed, and a pair of catches. The hook and tab combine to lock the post into position and to release the post so that the post can rotate. The engagements between the hook and the post and between the tab and the post permit rotation of the implant in situ. The stops and catches define an articulation range for the implant relative to a longitudinal axis of the inserter. A related method of using the system is also provided.

Abstract: A screwdriver for resisting premature disengagement of a screw from the screwdriver. The screwdriver includes a shaft having a central axis; a tip radially aligned with the central axis of the shaft which includes an end opposite the shaft, at least one radial protrusion extending away from the central axis, and a notch; and a screw retention mechanism including a flexible member aligned with the notch and attached to either the tip or the shaft. The flexible member has an unattached end which is separated from the second end of the tip. When the tip is inserted into a recess of a screw, the flexible member flexes toward the central axis and creates an opposing elastic force which holds the screw to the tip.

Abstract: Implants are formed from a multiple staged process that combines both additive and subtractive techniques. Additive techniques melt powders and fragments of a desired material, then successively layer the molten material into the desired implant shape, without compressing or remelting for homogenization of the layers, thereby producing an implant that is substantially free of pores and inclusions. Subtractive techniques refine implant surfaces to produce a bioactive roughened surface comprised of macro, micro, and nano structural features that facilitate bone growth and fusion.

Abstract: A system for affixing a stop plate to an interbody implant. The system includes a clamping device, a stop plate, and an inserter tool. The clamping device includes a body, a first clamping portion attached to the body including a stepped seat and a guide slot, and a second clamping portion attached to the body by a spring. Compressing the spring moves the second clamping portion away from the first clamping portion and expanding the spring moves the second clamping portion toward the first clamping portion.
