Hi, Before I explain you the meaning of the report, I would like to give some anatomical details. The vertebral column consists of vertebrae. The bodies of vertebrae are separated with disk-shaped cartilages. The posterior elements of the vertebrae comprise a canal where the spinal cord is located and is surrounded with a multilayer coating called thecal sac. There are also little holes on both sides of the vertebral column through which nerves originating from the spinal cord exit (neural foramina). The whole vertebral column is reinforced with tough ligaments both in the anterior and the posterior aspects. These ligaments are called anterior and posterior longitudinal ligaments, respectively. Each vertebra is marked with a letter that corresponds to the anatomic region of the body: C means cervical, T or Th means thoracic, L means lumbar, S is sacral. Now, back to your report. It says that the disk-shaped cartilages at levels C3-4, C4-5, C5-6 and C6-7 bulge (bump out) into the canal where the spinal cord is. This results in narrowing of the canal. The disks also compress the nerves that originate from the spinal cord at their exit through neural foramina. The radiologist also noted spasm of your neck muscles. Kind Regards,
