Abstract
An orthopedic fixation system includes a fastener configured to secure a first bone with a second bone whereby the fastener stabilizes the first bone relative to the second bone. The fastener includes an elastic component that provides the fastener with the ability to accommodate relative motion between the first bone relative to the second bone.

1-15. (canceled)
An orthopedic fixation system, comprising:
- a screw including a natural insertion shape, the screw being configured to secure a first bone with a second bone whereby the screw stabilizes the first bone relative to the second bone, the screw, comprising:
- an upper shaft with a top end and a bottom end, the upper shaft including threads about at least a segment thereof,
- a lower shaft with a top end and a bottom end, the lower shaft including threads about at least a segment thereof, and
- a series of interconnected individual geometric shapes formed from a superelastic shape memory material connecting the upper shaft at the bottom end thereof with the lower shaft at the top end thereof;
- the series of interconnected individual geometric shapes being configured to allow the screw to move from the natural insertion shape to an elastically deformed shape in response to a stress applied to the screw during a relative motion between the first bone and the second bone;
- the series of interconnected individual geometric shapes being configured to allow the screw to return from the elastically deformed shape to the natural insertion shape upon a removal of the stress applied to the screw;
- and
- the series of interconnected individual geometric shapes being configured to provide the screw with the ability to repeatedly cycle between the natural insertion shape and the elastically deformed shape such that the screw accommodates relative motion between the first bone relative to the second bone.
