Obstetric brachial plexus injuries.

It is clear that OBPP will continue to be a challenge for the foreseeable future. Because it is a rare condition the best results occur in specialised units for the fairly small number of patients who do not make a full recovery within two to three months of birth. This figure varies from 10 to 80%, according to the literature. Early referral to a specialist unit if there is not full, or almost full recovery, by two months will ensure that patients with OBPP obtain the optimal treatment available.
