Relationship of age and type of obstetric brachial plexus paralysis in forearm pronosupination.

OBJECTIVE: To evaluate the arc of forearm pronosupination of patients with sequelae of birth paralysis and correlate with these variables.

METHODS: 32 children aged between 4 and 14 years with total or partial lesions of the brachial plexus were evaluated; measurements of pronation and supination, active and passive, were made, both on the injured side and the unaffected side.

RESULTS: A statistically significant difference was observed between the injured side and the normal side, but there was no difference between the groups regarding age or type of injury.

CONCLUSION: The age and type of injury did not impact on the limitation of the forearm pronosupination in children with sequelae of birth paralysis.
