Isobar® Semi-Rigid Rod

Alphatec OsseoFix

The Isobar is a pedicle screw based semi-rigid rod designed to be part of an adjunct to fusion construct. The Isobar semi-rigid rod provides stabilization and controlled motion of the functional spinal unit while simultaneously sharing load with the interbody device. The load sharing with the interbody device, based on Wolff’s law, increases the potential of a fusion while simultaneously reducing stress on the screw-to-bone and screw-to-rod interfaces.
