Abstract: A method and system for reducing and affixing two separated bone segments, the system having a bone plate with a pair of positioning slots, and a pair of elongated manipulating members with anchoring structures, the anchoring structures sized to pass through the positioning slots and for advancement into the bone segments. The bone plate is loosely mounted to the bone segments across the separation gap and a manipulating member is screwed into each bone segment through a positioning slot. The manipulating members are then used to reposition the bone segments by moving them together longitudinally within the slots. Fixation bone screws are inserted into the bone segments through screw receiving apertures to securely affix the bone plate to the repositioned bone segments. The manipulating members are then removed.

Abstract: A surgical device includes one or more cameras integrated therein. The view of each of the one or more cameras can be integrated together and provided to a surgeon display and/or an assistant display. A surgical tool that includes an integrated camera may be used in conjunction with the surgical device. The image produced by the camera integrated with the surgical tool may be associated with the images generated by the one or more cameras integrated in the surgical device. The position and orientation of the cameras and/or the surgical tool can be tracked, and the surgical tool can be rendered as at least partially transparent. A surgical device may be powered by a hydraulic system, thereby reducing electromagnetic interference with tracking devices.

Abstract: A vertically expandable intervertebral cage, deployment devices, and methods for using the same. The intervertebral cage can include a circuitous body at least partially enclosing an interior volume. The intervertebral cage can also include a front panel which can be formed into a wedge for facilitating implantation of the intervertebral cage into an intervertebral space. The intervertebral cage can be converted from an undeployed configuration, wherein the height of the intervertebral cage is reduced, to a deployed configuration, wherein the height of the intervertebral cage is increased to support end plates of the vertebrae. The intervertebral cage can be converted from the undeployed configuration to a deployed configuration by using a deployment device such as an implantation device and a guide wire. The deployment device can be used to impart a force upon the cage.

Abstract: A rongeur including a base, which includes a handle portion, a body portion and a shaft portion. The shaft portion is made of a metal material and includes a male mold-on interlock portion configured to non-removably interlock with an over-molded plastic material. The body portion is made of plastic material and includes an over-mold interlock portion that is over-molded onto and non-removably fixed onto the mold-on interlock portion of the shaft portion. A slide shaft of the rongeur includes a distal portion and a proximal portion. The distal portion is made of a metal material and includes a male mold-on interlock portion configured to non-removably interlock with an over-molded plastic material.

Abstract: An anchor to be screwed into a hole and self-lock therein with high initial stability. The anchor has an aggressively-threaded, self-tapping apical end. A central region of the anchor is formed with a plurality of helical flutes and intervening lands. Each land carries a condensing edge. The condensing edges are configured to apply a circumferentially sweeping compressive strain to the interior surface of the host material while the anchor is being screwed into position. A coronal end of the anchor includes a corking feature to mitigate mushrooming around the perimeter of the hole. A helical groove intersects the condensing edges and flutes. The helical groove has a variable pitch and a decreasing depth which functions to squeeze and displace trapped host material thereby enhancing stability and other benefits. In bone applications, the groove hosts material chips which promote and enhance healing.

Abstract: A wedge osteotomy method inserts a first wire into a first bone of the foot, distal from tissue to be removed. A second wire is inserted into a second bone, so the tissue to be removed is distal from the second wire. A cut guide is pivoted about the first wire, until a first axis of the cut guide is parallel with a longitudinal axis of the first metatarsal. The cut guide has a slot perpendicular to the first axis for guiding a cutter to cut bone, while the first axis is aligned with the longitudinal axis of the first metatarsal. The cut guide is then pivoted about the second wire, until the first axis is aligned with the longitudinal axis of the talus, and bone is cut through the slot, to form a second planar cut into or through bone material.
