Erb's palsy, also known as Erb-Duchenne palsy, is a form of brachial plexus injury. The brachial plexus is a network of nerves that originates near the neck and shoulders and is responsible for providing movement and sensation to the arm, hand, and fingers. Erb's palsy typically involves damage to the upper brachial plexus nerves, specifically the C5 and C6 nerve roots.
Causes Erb's palsy commonly occurs during childbirth when an infant's neck is stretched to the side during a difficult delivery. Risk factors include:
Large birth weight Breech birth Prolonged labor Use of forceps or vacuum extraction during delivery Symptoms Symptoms of Erb's palsy can vary in severity and may include:
Weakness or paralysis in the affected arm Loss of sensation in the arm or hand Partial or complete loss of movement in the shoulder, arm, or hand Muscle atrophy in severe cases Diagnosis Diagnosis of Erb's palsy typically involves a physical examination, assessment of the infant's arm movements, and sometimes imaging studies such as X-rays, MRI, or ultrasound to evaluate the extent of nerve damage.
Treatment Treatment options depend on the severity of the injury and can include:
Physical therapy to improve strength and range of motion Occupational therapy to assist with fine motor skills Surgery in severe cases, which may involve nerve grafts or transfers Prognosis The prognosis for Erb's palsy varies. Many infants recover fully with appropriate therapy, while others may have lingering weakness or limited movement. Early intervention and consistent therapy are crucial for improving outcomes.
