Synonyms Brachial Plexus Birth Injuries, Dejerine Klumpke

What are Erb-Duchenne and Dejerine-Klumpke Palsies?

The brachial plexus is a network of nerves that conducts signals from the spine to the shoulder, arm, and hand. Brachial plexus injuries are caused by damage to those nerves. Erb-Duchenne (Erb’s) palsy refers to paralysis of the upper brachial plexus. Dejerine-Klumpke (Klumpke’s) palsy refers to paralysis of the lower brachial plexus. Although injuries can occur at any time, many brachial plexus injuries happen when a baby’s shoulders become impacted during delivery and the brachial plexus nerves stretch or tear. There are four types of brachial plexus injuries: avulsion, the most severe type, in which the nerve is torn from the spine; rupture, in which the nerve is torn but not at the spinal attachment; neuroma, in which the nerve has torn and healed but scar tissue puts pressure on the injured nerve and prevents it from conducting signals to the muscles; and neuropraxia or stretch, in which the nerve has been damaged but not torn. Neuropraxia is the most common type of brachial plexus injury. Symptoms of brachial plexus injury may include a limp or paralyzed arm; lack of muscle control in the arm, hand, or wrist, and lack of feeling or sensation in the arm or hand.
Is there any treatment?

Some brachial plexus injuries may heal without treatment. Many children who are injured during birth improve or recover by 3 to 4 months of age. Treatment for brachial plexus injuries includes physical therapy and, in some cases, surgery.

What is the prognosis?
The site and type of brachial plexus injury determines the prognosis. For avulsion and rupture injuries, there is no potential for recovery unless surgical reconnection is made in a timely manner. The potential for recovery varies for neuroma and neuropraxia injuries. Most individuals with neuropraxia injuries recover spontaneously with a 90-100% return of function.

What research is being done?
The NINDS conducts and supports research on injuries to the nervous system such as brachial plexus injuries. Much of this research is aimed at finding ways to prevent and treat these disorders.

	Did You Know?
	Information Is Available On Birth Defects If your child has a birth defect, you should ask his or her doctor about local resources and treatment. Geneticists and genetic counselors are another resource. CDC can give you general information about birth defects. For other birth defects, you may contact one of many national groups. These groups have fact sheets or brochures or can direct you to support groups, where you can meet and talk with other parents of children with the same type of birth defect. Many support groups also have brochures and books to help you learn more about birth defects.
