Obstetric brachial plexus injury also known as birth related brachial plexus injury has a reported incidence of 0.15-3 per 1000 live births. The extent of the injury varies from involvement of one trunk to involvement of all the roots and trunk which is called pan plexopathy. Physiotherapy is essential for the patient not only to prevent the contracture but also to detect the early signs of recovery and to encourage the child for spontaneous movement of the limb. The present report describes the case of a 11 months’ female child with obstetric pan brachial plexopathy treated with surgery and is presently undergoing physiotherapy.
