Patent ID: 8147499

Claim:
A dynamic distractor comprising: an elongate pusher block having a distal portion movable in a proximal to distal direction along its longitudinal axis; a first elongate arm having a first baseplate ending at a distal end thereof; a second elongate arm having a second baseplate ending at a distal end thereof, wherein the first and second elongate arms each include a recess together which form a relief location between the first and second elongate arms, the first and second elongate arms being resiliently coupled and configured to lie adjacent to one another at proximal portions thereof and are configured to deflect away from one another such that the first and second elongate arms are curved from the relief location to the distal portions thereof when the first and second baseplates are separated from one another; a first connector rotatably coupled to the first baseplate; a second connector rotatably coupled to the second baseplate, wherein the first connector and the second connector are also rotatably coupled to the distal portion of the pusher block.
