The embodiments provide spinal fusion devices such as interbody fusion and vertebral replacement devices for insertion into a patient's intervertebral disc space for restoring disc height, or for treating a deficient vertebral column by replacing and restoring the bony anatomy respectively. These fusion devices may be provided with an engineered cellular structure component to support biological activity and promote new bone growth. In addition, these fusion devices can also include internal imaging markers that allow the user to properly align the device and generally facilitate insertion. The imaging marker shows up as a solid body amongst the mesh under x-ray, fluoroscopy, CT scan, or other visualization techniques. |
