What is brachial plexus palsy in newborns?
Brachial plexus palsy is a problem with the nerves to the baby's arm. The brachial plexus is a bundle of nerves that runs between the spine and the arm. If one of the nerves is stretched or injured, it can weaken the nerve signals to the muscle and make it hard for the baby to move the arm.
Often it's not clear how the nerve was damaged. Sometimes it happens with a difficult birth.
The doctor can tell which nerves were affected by noting how the baby moves. The baby may not move the affected arm as much as the other one or may hold the hand at an angle.
The affected arm usually gets better in about 3 months. In some cases, the nerve damage can last longer or be a permanent problem.
How is brachial plexus palsy in newborns treated?
- Gentle massage and range-of-motion exercises at home may help your baby. The doctor will give you instructions about how to do this.
- Your baby may get physical therapy until the weak arm starts to get stronger. Sometimes splints are used to prevent contractures.
- In severe cases, surgery may be done to repair the nerve. It may take from 3 to 9 months to know if surgery is needed.
