Erb palsy

Erb's Palsy is a medical condition that primarily affects the arm's nerves, leading to paralysis or weakness. It is also known as Brachial Plexus Injury or Brachial Plexus Palsy. This condition is often associated with birth injuries, particularly those involving shoulder dystocia.

Causes[edit | edit source]

Erb's Palsy is typically caused by an injury to the upper group of the arm's main nerves, specifically the upper trunk C5-C6 nerves. These nerves form part of the brachial plexus, a network of nerves that send signals from the spine to the shoulder, arm, and hand. The most common cause of this injury is a difficult or traumatic birth, such as a breech birth, prolonged labor, or the use of forceps or vacuum devices.

Symptoms[edit | edit source]

The symptoms of Erb's Palsy can vary depending on the severity of the nerve damage. They may include weakness in one arm, loss of feeling in the arm, partial or total paralysis of the arm, and inability to use certain muscles in the arm or hand. The arm affected by Erb's Palsy may also hang limp to the side.

Diagnosis[edit | edit source]

Diagnosis of Erb's Palsy is usually made through a physical examination and the patient's medical history. In some cases, imaging tests such as MRI or CT scan may be used to confirm the diagnosis and assess the extent of the nerve damage.

Treatment[edit | edit source]

Treatment for Erb's Palsy depends on the severity of the condition. Mild cases often improve with physical therapy and exercises to strengthen the arm muscles. In more severe cases, surgery may be required to repair the damaged nerves. The prognosis for recovery is generally good, especially if treatment begins within the first year of life.
