Disc replacement typically occurs at cervical spine levels C4-5, C5-6, or C6-7. The first seven vertebrae make up the cervical spine. Doctors often refer to these vertebrae as C1 to C7. The cervical spine starts where the top vertebra (C1) connects to the bottom of the skull. The cervical spine curves slightly inward and ends where C7 joins the top of the thoracic spine (the chest area) at the first thoracic vertebra, T1.

Actor Christopher Reeve, best known for his role as Superman, is paralyzed and cannot breathe without the help of a respirator after breaking his neck in a riding accident in Culpeper, Va., on Saturday.
Reeve suffered fractures to the top two vertebrae, considered the most serious of cervical injuries, and also damaged his spinal cord, John A. Jane, the University of Virginia neurosurgeon treating Reeve in Charlottesville, revealed yesterday.
