## Abstract

In one form, a bone compression device is provided having a shape-retentive bone plate with an initial, unflexed configuration and a flexed configuration. The bone plate may be shifted to the flexed configuration and secured to bones using bone screws of the bone compression device. Once the bone plate has been secured to the bones, the bone plate returns toward its unflexed configuration which compresses the bones.
