Causes of Erb’s Palsy
If you or someone you love has suffered with brachial plexus palsy, you are probably very familiar with both of these terms, the causes, effects, and failures. If you are not, then you need to be. If you’ve never had an encounter with Erb’s Palsy, as it is referred to, count your blessing, but be aware.
Erb’s is caused by an injury to the nerves that effect the neck and upper chest. These nerves supply feeling, control, and can cause pain to the shoulders and arms. Injuring any nerve can and usually does cause some kind of loss of control or pain and this one is no exception. Damaging the brachial plexus can lead to loss of feeling and/or movement in arms, hands, and fingers.
How often does this occur?
About 3 of every 1000 live births has an occurrence of Erb’s Palsy. About 25% of these occurrences suffer permanently. Erb’s Palsy is graded into forms depending on the degree of paralysis.
So how does this happen?
This injury can occur during childbirth. When a baby becomes lodged behind the mother’s pubic bone (shoulder dystocia), if the correct delivery techniques are not used, Erb’s Palsy, a possible permanent lifetime of impairment, can be the result.
