Claim Text:
1. An adjustable screwdriver for selectively driving an adjustable compression screw into a substrate, the adjustable compression screw having a screw shaft and a separate adjustable head threaded on a head of the screw shaft, comprising: a handle, an adjustable head driver extending distally from said handle, a distal tip of said adjustable head driver configured to engage the adjustable head of the adjustable compression screw for use in rotating the adjustable head of the adjustable compression screw, a shaft driver concentrically disposed in said adjustable head driver, said shaft driver fixed in said handle, a distal tip of said shaft driver configured to engage the head of the screw shaft of the adjustable compression screw for use in rotating the screw shaft, said shaft driver configured to selectively lock in an even driving position wherein said distal tip of said shaft driver is substantially even with said distal tip of said adjustable head driver to thereby allow said adjustable head driver and said shaft driver to cooperatively drive the adjustable head and the screw shaft, and said shaft driver configured to selectively lock in a retracted driving position wherein said distal tip of said shaft driver is recessed in said adjustable head driver to thereby allow said adjustable head driver to drive the adjustable head without said shaft driver driving the screw shaft.
