Obstetric palsy is a birth injury that occurs when the brachial plexus is damaged by traction. In the majority of patients spontaneous recovery will occur; however, in case of incomplete spontaneous recovery early neurosurgical intervention may be indicated. We present 3 case reports in this article, as well as describing the strategy favoured in our clinic. We recommend referring patients who have incomplete spontaneous recovery at the age of 1 month. At that age a good prediction of prognosis can be made by combining neurological examination with needle electromyography (EMG) of the biceps muscle.
