Abstract: A surgical retractor includes a body portion and first and second retractor arms operatively coupled thereto. The body portion includes a rotatable knob, a first blade holder, and a first blade. The first blade is configured for axial displacement with the first blade holder and angulation relative to the first blade holder about a first axis. The first and second retractor arms include respective second and third blades detachably secured thereto. The first and second retractor arms are transitionable between an approximated configuration and a spaced apart configuration. The second and third blades are configured to angulate about respective second and third axes that are defined by the respective first and second retractor arms.

Abstract: A precision depth guided instrument, such as a Jamshidi needle, is provided for use in various surgeries related to the vertebrae. The instrument includes an outer cannula, an inner cannula and a stylet. After the cortical bone of a vertebra is penetrated by the outer cannula of the instrument, the depth of penetration of the inner cannula is adjusted by rotation of the inner cannula. The inner cannula is then moved further into the vertebrae, and a stop mounted on the outer cannula controls the depth of penetration of the inner cannula. The correct depth of penetration is determined by radiography prior to the procedure.

Abstract: The present invention relates to an implantable intervertebral device that is made of a bone body substantially conforming in size and shape with the enplates of adjacent vertebrae. The bone body has a top surface, a bottom surface, and, a cavity, which extends from the top surface to the bottom surface. The cavity is filled with osteoconductive or osteoinductive graft material.
