Identify a spinal posterior (dorsal) root ganglion. The posterior root ganglion lies at the level of the intervertebral foramen (Figure 2.4) and is located in the posterior root of the spinal nerve. .

To expose one of these ganglia, place a probe into an intervertebral foramen, between adjacent thoracic vertebrae, to protect the spinal nerve within it. Use bone pliers to remove the articular process lying posterior to this foramen.
