cage, fusion: A hollow titanium cylinder or box,  that holds two vertebrae in place and carries bone graft material in its interior.


cancellous bone:  The loose, open, lattice of bony material within the center of many bones.


carbon fiber: Material used in aeronautics and increasingly in medicine, that provides a hard, lightweight structure.


carotid artery: One of the main arteries running up the neck and into the face and brain. 


carpal tunnel: A structure within the wrist that carries the tendons and the nerves into the hand from the forearm.


carpal tunnel syndrome: A compression at the wrist, that causes a pinch of the median nerve affecting the thumb, 2nd and 3rd fingers of the hand.


CAT scanning: X-ray based system for producing cross-sectional images for medical examination.


catheter: A tube used for delivery of fluids or withdrawing fluids.


caudal: Towards the lower end of the body.


caudal epidural: An injection into the epidural space placed through the sacrum.


causalgia: A nerve-based pain associated with nerve or bodily injury.


cell saver: A machine that aspirates blood lost during surgery and cleans it for re-transfusion back into the patient’s body.


central canal: The central portion of the vertebral column in which the spinal cord is found.


central nervous system: The brain and spinal cord.


central pain: Pain that is based primarily in abnormal function within the spinal cord or brain.


cerebellar tonsils: The lowest end of the brain that may, in some conditions, extend through the level of the foramen magnum.


cerebellum: A posterior and low portion of the brain involved in the smooth coordination of movement.


cerebral cortex: The upper, superior covering over the brain involved in higher level integration and thought.


cerebral palsy: An associated condition with birth in which abnormal levels of spasticity prevent normal limb movement.


cerebrospinal fluid: A clear fluid that bathes the brain and spinal cord.


cervical: Associated with the neck.


cervical spine: The vertebrae in the neck.


cervical plate: A titanium device used to secure and hold cervical vertebrae in place during the time that they are fusing after a surgery.


chelator: A chemical that removes metal ions from solution.


chest tube: A catheter tube placed through the chest wall to help re-inflate a collapsed lung.


chiropractic: A process of manipulation of the vertebrae and spine to achieve relief of pain or muscle spasm.


chyle: A fluid produced in the digestive tract and that carries nutrients from digestion up the thoracic duct and into the neck it flows into the venous system.


claudication: Leg pain with walking, associated either with inadequate blood supply to the legs or circumferential compression of the spinal canal.


clotting factors: Chemicals in the blood that allow the blood to form clots and halt bleeding. 


coblation: A heat-based process for evaporating disc material.


coccyx: The lowest portion of the spine.


cohort study: A research evaluation of a spinal technique, that follows a large number of patients with similar conditions to assess the affect of different treatments.


Complex Regional Pain Syndrome (also: Reflex Sympathetic Dystrophy): Type of paint that does not respond to the usual medications and that involves the autonomic nervous system.


compression stockings: Stockings worn to prevent the pooling of blood in the veins and to reduce the risk of deep vein clots (thrombosis) in the legs.


concordant: The experience of pain during a disc injection procedure, implying that the pain is similar to the pain the patient usually experiences from their condition.


consent form:  Statement of understanding by the patient of the nature of a medical intervention giving the permission for the treating physician to proceed.


contrast agent:  An injected material that helps distinguish the appearance of two or more tissues during radiological imaging tests.


cortical bone:  The hard outer aspect of bone.


cortical responses:  Electrical activity on the surface of the brain (cerebral cortex) detected by an evoked potential monitoring system.


costovertebral:  The area of the thoracic spine where the rib meets the vertebra.


Cox II inhibitors:  Nonsteroidal anti-inflammatory medications that are less irritating to the stomach than the routine nonsteroidal anti-inflammatory medications.


CPT:  Current procedural terminology.  A code system for providing a numerical description of the various components of medical care.


cranial:  Towards the head or associated with the skull.


cranium:  The skull.


cubital tunnel:  An area in the distal humerus (upper arm bone) through which the ulnar nerve passes as it crosses the elbow.  In general, the area of the “funny bone.”


cyst:  An abnormal enclosed fluid space within the body.
