Abstract:
1. An orthopedic device for surgical treatment of bone, comprising: a tubular body defining a longitudinal axis; a plurality of splines integrally formed from the tubular body between first and second regions of the tubular body, wherein the splines are substantially aligned with the longitudinal axis in a collapsed state, and movable substantially transversely outwardly relative to the longitudinal axis to define an expanded state; and an elongate control member disposed within the tubular body, the elongate control member having a first end non-threadably coupled to the first region of the tubular body and a second end threadably coupled to an actuating element disposed within the tubular body; wherein rotation of the actuating element in a first direction about the longitudinal axis causes the control member to move linearly within the tubular body relative to the second region of the tubular body, thereby moving the splines from the collapsed state to define the expanded state; and wherein rotation of the actuating element in a second direction about the longitudinal axis causes the control member to move linearly within the tubular body relative to the second region of the tubular body, thereby moving the splines from the expanded state to the collapsed state.
