总结

• Involves an injury to the nerves of the arm derived from the C5 to C6 levels of the spinal cord.
• Presents in a newborn with decreased movement of the involved arm, usually in the 'waiter tip' position.
• Typically recovers over the course of the first 6 to 12 months of life.
• Physiotherapy or occupational therapy is used in children with brachial plexus birth palsies in order to maintain motion and prevent contracture as the nerves reinnervate muscles affected by the initial injury.
• Nerve reconstruction or muscle transfer surgery may be needed to improve function in children with incomplete recovery.
