Identifying Symptoms of Erb’s Palsy and Other Brachial Plexus Birth Injuries
In a newborn, a brachial plexus injury doesn’t come with any visible wounds or trauma.
The damage is internal, so signs can be easy to miss in the first hours and days. What parents and especially trained nurses will notice, however, are the following:
- The baby will not or cannot move one arm
- The baby keeps one arm bent at an odd angle, hand turned inward
- A weaker or absent grip in one arm or hand
- No startle reflex in one arm
Any or all of these signs can point to a problem. The specific condition depends on which nerves have been damaged.
Erb’s palsy, the most common brachial plexus injury in newborns, affects the upper nerves that control the shoulder and upper arm.
Klumpke’s palsy affects the lower nerves that control the hand and wrist.
A global, or total injury, affects the entire arm. This is the most severe injury.
These situations are not hopeless. In fact, many babies with Erb’s palsy improve. With early physical therapy and time, 70 to 90 percent of newborns recover much of their functions within the first few months. Babies born with Klumpke’s palsy don’t always recover so quickly.
For them, more medical attention could be necessary. However, a newborn with a rupture or avulsion injury cannot heal without surgery. The clearest sign of a rupture or avulsion is a limp, completely unresponsive arm.
The sooner the specific injury is identified, documented, and treated, the stronger your case and the more optimistic your child’s outlook will be.
