An instrument for spinal procedures is a vertebral endplate spreader device having a vertebral endplate spreader and a driver handle. The vertebral endplate spreader includes a linkage with a drive sprocket operatively connected for rotation relative thereto and with a secondary sprocket. The secondary sprocket is operatively connected for rotation relative to the linkage. The vertebral endplate spreader includes a belt operatively connected to the drive sprocket and the secondary sprocket to be driven about a belt axis. The driver handle has a distal end and a proximal end. The distal end is operatively connected to the drive sprocket to actuate rotation of the belt.
