Abstract

An expandable reamer for forming a space within a vertebral disc includes a pair of opposing blades which have a expanded state and a retracted state. The blades being pivotally positioned at the distal end of a shaft assembly. A shaft housing being substantially disposed about the shaft assembly. The proximal end of the shaft assembly being operatively engaged by a control device which when rotated allows the blades to be fully retracted for insertion into a pre-bored hole and then to be expanded incrementally until the cavity is bored as desired.
