Obstetric palsy is a brachial plexus injury at birth. In our country, its prevalence is unknown, but the dysfunction of the affected limb are frequent and often long lasting. Shoulder dystocia is defined as the need to maneuver to the delivery of the shoulders, or a range greater than 60 seconds between deliveryng the head and shoulders. It is related to 50% of cases of brachial plexus injury. Most cases occur in the absence of risk factors. The maneuvers of assisted childbirth with shoulder dystocia should be trained and stored. The approach of the brachial injury must be multidisciplinary. Physiotherapy, microsurgical reconstruction of the plexus, secondary correction of joint deformities and muscle transpositions are employed successfully. The role of conservative treatment and surgical procedures should be regularly reviewed. The aim of this study was performed a literature review about obstetrics brachial plexus palsy.
