Erb's Palsy
Types of Erb's Palsy
There are different types of brachial plexus injuries. Children with
Erbs
palsy are all affected in different ways. The variations are that some children
will not have any muscle control or feeling in the arm or hand while some children
can move their arms but have little control over the wrist and hand with other
children able to use their hands well but cant use their shoulder or
elbow muscles. Depending on the type of nerve damage in Erbs palsy children
the symptoms can range from mild to severe. With Erbs palsy there are
four different types of nerve injuries, including:
- an avulsion meaning the nerve is torn from the spine
- a rupture meaning the nerve is torn but not where it attaches to the
spine
- a neuroma meaning the nerve has tried to heal but scar tissue has
grown around the injury and the scar tissue puts pressure on the injured
nerve
- praxis meaning that the nerve has been damaged but not torn but improvement
should be seen within 3 months.
Neuropraxia is the mildest form of a nerve injury. Neuropraxia,
the most common form of Erbs palsy is only at the specific place
where the injury occurs, and is a physiologic block of nerve conduction
within an axon without any anatomical interruption. Many infants born with brachial
plexus palsy have neuropraxia and sometimes recover spontaneously because
it sometimes disappears within 4-6 weeks.
Axonotmesis nerve damage in Erbs palsy injuries is characterized
by axonal and myelin sheath damage that ends with partial interruption
of the connective tissue framework. This form of Erbs palsy requires
a re-growth of the axon to the target muscle. A complete absence of sensory
modalities should be expected though recovery is fairly good.
Neurotmesis is the greatest degree of nerve injury in Erbs
palsy. There is complete disruption of the axon and supporting connective
tissue. At birth Erbs palsy is associated to neurotmesis and has
no recovery. One or more of the nerves in the brachial plexus may be affected
and injured and may be the same type of injuries or different. Due to the
fact that the injuries cause the same symptoms it is hard to distinguish
what type of injury has occurred.
