Klumpke's palsy

Klumpke's palsy is a form of brachial plexus injury that affects the lower roots of the brachial plexus, a network of nerves that sends signals from the spine to the shoulder, arm, and hand. It is named after Augusta Dejerine-Klumpke, a pioneering French neurologist who first described the condition.

Causes

Klumpke's palsy is typically caused by a birth injury, particularly during a difficult delivery. It can also occur as a result of a traumatic injury, such as a fall or accident. The injury involves damage to the eighth cervical (C8) and first thoracic (T1) nerves, which can be stretched, compressed, or, in the most severe cases, torn.

Symptoms

The main symptoms of Klumpke's palsy include weakness or paralysis in the hand and forearm, and a characteristic "claw hand" deformity. Sensation may also be affected, and in severe cases, the condition can cause Horner's syndrome, which involves a drooping eyelid and smaller pupil on the affected side.

Diagnosis

Diagnosis of Klumpke's palsy is based on physical examination and the patient's medical history. Imaging tests such as MRI or CT scan may be used to confirm the diagnosis and assess the extent of the injury.

Treatment

Treatment for Klumpke's palsy depends on the severity of the injury. Mild cases may improve with physical therapy and occupational therapy. In more severe cases, surgery may be required to repair the damaged nerves. Prognosis varies, but with early intervention and appropriate treatment, many individuals with Klumpke's palsy can lead normal lives.
