Treatment:

Gentle massage of the arm and range of motion exercises are recommended for mild cases. More severe cases may need to be evaluated by several specialists.

If some strength has not returned to the affected muscles by the time the baby is 3 - 6 months old, treatments may include:

• Surgery on the nerves
• Tendon transfers to help the muscles that are affected by nerve damage work better

Expectations (prognosis):

A full recovery is expected in most cases. Most infants recover within 6 months, but those that do not recover have a very poor outlook.

The benefit of surgery to try to repair the nerves or compensate for the nerve deficit is not clear.

In cases of pseudoparalysis, the child will begin to use the affected arm as the fracture heals. Fractures in infants usually heal very quickly and easily.

Complications:

Complications include:

• Abnormal muscle contractions (contractures) or tightening of the muscles, which may be permanent
• Permanent, partial, or total loss of function of the affected nerves, causing paralysis of the arm or arm weakness

Calling your health care provider:

Call your health care provider if your newborn shows a lack of movement of either arm.
