Are there various degrees of severity with a Brachial Plexus Injury?
A. There are four basic types of nerve injuries. Some people only have one type while others have a combination of two or more types. Avulsion- the nerve is detached from the spinal cord. Rupture- the nerve is separated from itself, but not at the juncture of the nerve and the spinal cord. There may be one or more ruptures in a single nerve. Praxis or Traction- the nerve is typically overstretched and damaged, but not detached from itself or the spinal cord. Neuroma- scar tissue has surrounded the injured nerve and excessive pressure is now placed on the nerve. Therefore, the nerve has trouble getting all the signals to the muscle to be able to perform a movement.
