Abstract: An interspinous stabilizer, comprising: an interspinous spacer, comprising a central support, having a first direction and a second direction opposite to each other, and an upper side and a lower side perpendicular to the first direction and the second direction; an upper side wing is on the first direction and extending from the upper side of the central support; a lower side wing is on the first direction and extending from the lower side of the central support; an upper protrusion is on the second direction and extending from the upper side of the central support; a lower protrusion is on the second direction and extending from the lower side of the central support; at least one perforation, the perforation traversing through the first direction to the second direction of the central support.

Abstract: An auxiliary bone reinforcement structure includes a deformable hollow body having multiple bosses formed on an outer periphery of the hollow body and a connection portion, a connector detachably connected to the connection portion and having an annular groove defined in an outer periphery of the connector and an injector detachably connected to the connector for injection of a medicine into the hollow body whereby the hollow body is deformed after the medicine is injected into the hollow body and thus able to stuff a hole in the bone.
