Although a spine fusion surgery may be done at different levels throughout the spine (cervical, thoracic and lumbar sections of the spine), the preoperative preparation is similar for each type of fusion.
Radiograph to assess spinal instability
Myelogram, MRI, or CAT scan to identify nerve compression
EMG to test nerve function
All of these tests are done with the goal of more precisely planning the back surgery.
