Surgical instrument for moving vertebrae
First Claim
1. A surgical instrument for moving a first bone portion relative to a second bone portion, said surgical instrument comprising:
- a first portion having a longitudinal axis engageable with a first member connected with the first bone portion;
a second portion engageable with a second member connected with the second bone portion, said second portion being movable relative to said first portion; and
an actuator connected with said second portion for moving said second portion relative to said first portion in a direction extending transverse to said longitudinal axis to move the first and second bone portions relative to each other;
wherein said first portion has an end engageable with a clamping member threadably engaging a fastener connected to the first bone portion which clamps a longitudinal member extending between the first and second bone portions to the fastener, said first portion being rotatable about said longitudinal axis relative to the second portion to rotate the clamping member relative to the fastener.

Abstract
A surgical instrument extendable through a cannula for moving a first bone portion relative to a second bone portion includes a first portion having a longitudinal axis engageable with a first member connected with to the first bone portion. A second portion is engageable with a second member connected with the second bone portion. The second portion is movable relative to the first portion from a first position toward a second position to move the first and second bone portions away from each other. An actuator connected with the second portion moves the second portion relative to the first portion in a direction extending transverse to the longitudinal axis.
