Abstract
A device for stabilizing bone includes a tubular body having first and second end regions defining a longitudinal axis therebetween. A plurality of splines extend from the first end region, the splines including first ends coupled to the first end region, and second ends disposed away from the first end region, the second ends being directable from a generally axial collapsed state to a substantially transverse expanded state. A plurality of support arms are coupled to the splines, and an actuator is coupled to the support arms, the actuator movable axially relative to the elongate body for causing the support arms to direct the second ends of the splines from the collapsed state to the expanded state. Optionally, the device includes another set of splines extending from the second end region or located at an intermediate region of the tubular body.
