obstetric brachial plexus palsy

A specific type of brachial plexus injury caused by mechanical injury during a difficult childbirth, due either to excessive lateral flexion of the head on the trunk during delivery of the shoulders (shoulder dystocia), or delivery of the head in a traction injury to one or more components of the brachial plexus, resulting in stretching of the plexus.
