Abstract: An anchor-in-anchor fixation system is provided for securing underlying structure, such as bone. The fixation system includes a first bone anchor having a shaft for fixation to underlying bone, and a head that defines an internal bore. A second bone anchor extends through the bore and into underlying bone. A fixation assembly is also provided that includes one or more fixation systems coupled to an auxiliary attachment member configured for long bone fixation, spinal fixation, or fixation of other bones as desired.

Abstract: An intervertebral implant for insertion into an intervertebral disc space between adjacent vertebral bodies or between two bone portions. The implant includes a spacer portion, a plate portion operatively coupled to the spacer portion and one or more blades for securing the implant to the adjacent vertebral bodies. The blades preferably include superior and inferior cylindrical pins for engaging the adjacent vertebral bodies. The implant may be configured to be inserted via a direct lateral trans-psoas approach. Alternatively, the implant may be configured for insertion via an anterior approach.

Abstract: An expandable interbody spacer (10) is provided that includes a pair of oppositely facing endplate components (20, 40) and an interior component that includes one or more vertically extending stacks of arranged C-clip members (70) radially surrounding one or more bosses (30) protruding interiorly from one of the endplates, wherein the size and configuration of the bosses and the C-clip members are designed to allow the incremental expansion of expandable interbody spacer.

Abstract: A device for reaming a bone includes an elongated shaft extending along a first longitudinal axis from and first end to a second end, the shaft being sufficiently longitudinally flexible to enable it to be passed through a path having a curvature of a target bone and a reaming head extending along a second longitudinal axis from the second end to a third free end, wherein the first longitudinal axis is parallel to and laterally offset from the second longitudinal axis so that, upon rotation of the shaft, the reaming head rotates eccentrically with respect to the first longitudinal axis.

Abstract: The present invention is directed to an allograft intervertebral implant sized and configured for insertion between adjacent vertebral bodies in a spinal fusion surgery. The implant is preferably manufactured from two or more pieces of allograft bone joined together by a joint, more preferably a dovetail joint. The dovetail joint being sized and configured to substantially follow the exterior shape or surface of the intervertebral implant.

Abstract: The present invention is directed to an allograft intervertebral implant sized and configured for insertion between adjacent vertebral bodies in a spinal fusion surgery. The implant is preferably manufactured from two or more pieces of allograft bone joined together by a joint, more preferably a dovetail joint. The dovetail joint being sized and configured to substantially follow the exterior shape or surface (e.g. perimeter) of the intervertebral implant. The intervertebral implant may also include one or more bone pins for joining the allograft pieces, the pins being inserted into the implant at an angle substantially perpendicular with respect to the dovetail joint. The intervertebral implant may also include one or more through-bores for receiving ostegenic or bone graft material. The intervertebral implant is preferably sized and configured for insertion during a T-PLIF or PLIF procedure.
