A method and system is provided for repairing bone fractures at locations where high levels of stability are required. The system employs two plates to buttress a fracture from both the dorsal and volar sides. The plates are affixed to one another using screws that are installed from a volar plate, through the bone and into a dorsal plate. The method provides for use of a directional guide that allows the precise placement of Kirschner wires for temporary fixation of the fracture, installation of a first bone fixation plate using the installed K-wires for alignment, installation of a second bone plate adjacent the bone to be repaired and opposite the first bone plate, and installation of cannulated fasteners between the two opposing bone plates such that the fasteners rigidly engage both of the bone plates.

There is described an instrument set for use in spinal surgery that includes as elements a spinal body spacer, a placement tool, and an extraction tool. The spacer may be constructed with a body having a first wall and a second wall connected by a top face, a bottom face, and a lateral support. Further, the spinal body spacer has a threaded opening and keyways connected to the threaded opening positioned in a face. The spinal body spacer may also include a superior surface and an inferior surface with a plurality of antimigration furrows positioned on each of the superior surface and the inferior surface. The spacer may have an outer face positioned around the opening and the placement tool may also have a contact face such that the contact face comes into contact with the outer face when the placement tool is fully connected with the spacer. The placement tool has a threaded tip for connecting with the threaded opening of the spacer. The extraction tool has a tip configured to pass through the opening of the spacer, and the tool has tabs positioned on the tip such that the tabs pass through the keyways of the spacer. The extraction tool is configured such that it passes through the aperture, rotates, and then can be used to exert a pulling force on the spacer. The tip of the extraction tool may be a substantially blunt tip, a substantially pointed tip, or even a tip with a hollow area. The spacer may have at least one block disposed on an interior surface such that the block contacts the tabs of the extraction tool thereby restricting rotation of the extraction tool relative to the spacer. The spacer may have a backing plate, and the backing plate may itself include projections disposed in the matrix of the spacer.

An armor system has a hardened strike panel and a backing panel. The strike panel utilizes common hard materials such as granite, hardened concrete or ceramic tile. The backing panel utilizes reinforcement materials having high strength and stiffness to provide support to the strike panel upon impact of a projectile.

An interior panel assembly and an airbag device are provided that are equipped with structure for preventing an interior panel and a backing plate from becoming detached from each other. In one form, when an inflator discharges gas, movable door-frame members are moved (lifted) upward by being pushed upward by an inflating airbag. An instrument panel ruptures along a peripheral tear line, causing a door portion to be cut and separated from the surrounding instrument panel. Grooves serving as rupturable sections extend along joint sections between backing plates and leg plates of the movable door-frame members. When the backing plates of the movable door-frame members open outward together with the door portion, the grooves rupture to cause the backing plates to become partially separated from the leg plates. At the sections of the backing plates partially separated from the leg plates, the backing plates become substantially flat as a result of the partial separation from the leg plates.

A backing sheet, and a system and method of manufacturing a backing sheet with stapling tabs. The system includes a roller device configured to apply an adherent material to a first side of the backing sheet continuously fed from a feed roll. The sheet is then fed to a first pair of folders configured to fold the backing sheet along the edges such that the adherent material holds the first fold in place. The sheet passes through a second pair of folders that form a second fold along the edges of the sheet by folding in the opposite direction as in the first fold. Advantageously, an applicator device is configured to apply a tacky substance, such as a starch solution, between the contacting portions of the second fold, prior to the formation of the second fold. The tacky substance maintains the second fold and prevents the stapling tab from opening during further manufacturing and packaging processes. Alternatively, the system includes a piercing device configured to piece a hole through the backing sheet in order to allow a portion of adherent material to leak through the hole and contact a portion of the backing sheet. Once the second fold is made, the portion of adherent material extending through the hole will contact a portion of the backing sheet and will adhere to the portion of the backing material it contacts, and thereby prevent the stapling tab from opening during the remaining manufacturing and packaging processes.
