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.

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.

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.

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.

A system for anchoring implants to bones comprises a screw and fixation collar that when connected together inhibit axial movement of the screw and that when connected to an implant with a compatibly shaped aperture inhibit the screw's ability to back out from the bone and back out from the implant. The fixation collar includes a substantially C-shaped configuration partially surrounding a void, with first and second ends defining a gap that is slightly narrower in width than the diameter of the screw and being partially flexible to allow compression and expansion of the fixation collar to snap fit the collar around the screw.
