This exhibit depicts a C4-6 cervical discogram to determine the underlying cause of radiculopathy symptoms. Cervical nerve roots exit the spinal canal to provide motor and sensory nerve function to the upper body. Compression of these nerve roots can lead to radiating pain, numbness, or weakness throughout the corresponding dermatome. This is referred to as cervical radiculopathy. Nerve compression can be caused by protruding intervertebral disc materials, osteoarthritis, or other degenerative conditions of the spine. A cervical discogram is a procedure in which contrast dye is injected into a cervical disc for clearer radiological visualization. Upon injection, recurrence of the patient’s radiculopathy symptoms may signify the presence of a disc bulge or herniation. Magnetic Resonance Imaging (MRI), Computed Tomography (CT Scan), or X-Rays are then used to confirm the presence of intervertebral disc injury.
