Dynamic, rigid, and convertible dynamic-to-rigid devices and methods of using such devices to treat spinal instability conditions of the cervical spine are provided. The devices may include an interspinous, interlaminar stabilization device configured for interlaminar placement between the spinous processes of adjacent cervical vertebrae and optionally secured to the lamina using bone screws or crimped or rigidly fixed to the spinous process. Multiple devices may be used to enable treatment of multiple levels at the same time.
