Erbs Palsy is a paralysis or weakness of the muscles of the arm following an injury to a plexus of nerves in the upper limb region called the brachial plexus. An injury to part of this plexus results in weakness or paralysis of certain muscles in the arm. Though there are different types of injuries, Erbs palsy is the most frequently occurring one usually associated with assisted childbirth. The birth injury typically occurs when there is a stretch on the shoulder, arm or neck while assisting with delivery. This injury affects the C5-C6 nerve root and its deformity is commonly described as waiter’s tip deformity. Trauma, dislocation and gunshot can also cause brachial plexus injury in adults.
