Dynamic spinal stabilization members and methods

摘要

Devices and methods for spinal stabilization include first and second anchor assemblies engageable to respective ones of first and second vertebrae and a connecting element engageable to the first and second anchor assemblies. The connecting element includes opposite first and second anchor engaging end portions and a length along a longitudinal axis between the first and second anchor engaging end portions sized for positioning between and engaging each of the first and second anchor assemblies when the first and second anchor assemblies are engaged to the respective vertebrae. The connecting element further includes a support portion between the first and second anchor engaging end portions. The support portion includes first and second support members spaced from one another on opposite sides of the longitudinal axis, and a stabilizing member extending between the support members in a transverse orientation to the longitudinal axis.
