Abstract
A spinal construct for implantation in a patient to provide stabilization to spinal structure with improved load sharing includes a flexible spinal rod having a first end and a second end, the spinal rod being configured to provide stabilization to spinal structure. It also includes a first bone fastener configured to securely attach to the flexible spinal rod and a second bone fastener configured to securely attach to the flexible spinal rod. The second bone fastener is a dynamic fastener arranged to provide motion in one direction more than another direction. The flexible spinal rod and the second bone fastener are oriented to cooperate in a manner that achieves load sharing by dynamically flexing under applied loads in a manner that distributes stresses and strains between the flexible spinal rod and the second bone fastener.
