DEFINING DERMATOMES / CENTRAL CORD SYNDROME


SPINAL COLUMN
The spinal column is made up of a collection of bones that
protect the spinal cord. There are disks between the bones.
There are nerves in the spinal cord that originate from the 
brain.

SPINAL INJURIES
Injury to the spinal cord, may result in decreased sensation
to the extremities and torso.

CHECKING DERMATOMES
Checking dermatomes, is usually done by using a pin
and cautiously pricking the skin of the arms, fingers, 
legs and feet. In addition, asking the patient if the 
sensation is dull, sharp or absent.
It is important to document findings.

Spinal trauma


Scenario:The young lady in the image above,
fell off her horse. She sustained a spinal injury.
Spinal shock may be caused by hyperextension
or hyperflexion of the spinal column.Vasogenic
shock may also occur, leading to vasodilation
of the blood vessels, hypotension and bradycardia.

Central cord syndrome typically involves the central
part of the spinal cord. This unusual phenomenon
causes weakness of the upper extremities and minimal
or no weakness of the lower extremities.
