Routine shoulder ultrasound seen as appropriate for infants with brachial plexus birth palsy

July 20, 2017

Read the Perspective from Kevin Little, MD

Recently published results showed ultrasound screening is appropriate for infants with brachial plexus birth palsy with a passive external rotation in adduction of 60° or less used as the criterion to achieve appropriate sensitivity for ultrasound.

Researchers obtained data from an ultrasound screening program of 66 infants born between January 2011 and April 2014 with brachial plexus birth palsy. Researchers recorded details of a standardized physical examination, including active movement scale and measurement of passive external rotation of the shoulder, as well as ultrasound measurements that included the percentage of the humeral head displaced posterior to the axis of the scapular (PHHD) and the alpha angle. Researchers defined shoulder dislocation as both a PHHD of greater than 0.5 and an alpha angle of greater than 30°.
