RADIAL HEAD DISLOCATION AS A RARE COMPLICATION OF OBSTETRIC BRACHIAL PLEXUS PALSY: LITERATURE REVIEW AND FIVE CASE SERIES

Abstract

Radial head dislocation secondary to obstetric brachial plexus palsy is a rare complication that may occur a few years after birth. Five cases were examined and a comprehensive literature search was performed. Although it is a concern for parents, the dislocation resulted in mild or minimal functional impairment for all five children. Surgical interventions such as biceps tendon transfer, radial head open reduction or excision and annular ligament reconstruction were largely ineffective in significantly improving ranges of motion. Clinicians should be aware of the potentially futile outcomes and risks associated with the surgical treatment of radial head dislocation.
