Abstract: A bolster system having a first bolster device, a second bolster device, and an adjustable tether that includes a one-way pre-tied slideable adjustment knot. The adjustment knot is at a first position prior to insertion of the first bolster device into a passageway in one or more bones. The second bolster device includes a body portion having an outer portion that is sized to be received in the passageway and/or in an aperture of a bone plate. The body portion also includes a channel that is sized to accommodate recessed and/or embedded placement of the pre-tied slideable adjustment knot. The second bolster device can also include an oversized plate portion that abuts against a cortex of a bone or a wall of a bone plate. The second bolster device can also include a threaded member or retention tab that lockingly secures the second bolster device to a bone plate.

Abstract: A cartridge arrangement having a rocket assisted projectile for firing therefrom by ignition of propellant in the cartridge case and for subsequent ignition of a rocket grain within the projectile, in which the projectile has a sealed tubular chamber cavity encompassing a tubular or ring shaped end burning rocket grain, the rear end of which chamber is formed by a combined nozzle block and rear penetrator support which has nozzle openings sealed by ignitable time delay igniter plugs, and the outer, inner, and forward extremities of which are bounded by a thin-walled projectile case, a cylindrical penetrator, and a forward penetrator support, and which ignitable time delay igniter plugs are externally ignitable by the burning of the propellant to enable subsequent ignition of the adjacent end of the rocket grain.

Abstract: A cartridge arrangement having propellant therein and a rocket assisted projectile for firing therefrom by ignition of propellant in the cartridge case, the rocket assisted projectile having an annular securing skirt rearward of a nozzle block and surrounding rifling band, with spaced pressure equalizing vent openings in the securing skirt for pressure equalization relief during debulleting of the projectile from the cartridge case or casing.
