Morphologic Variants of Acromion in Neonatal Cadavers

Abstract

In this study, the morphology of the acromion in neonatal cadavers was investigated. The hooked-type acromions (Bigliani and Morrison type III), which are said to be responsible for rotator cuff lesions in adults, were found to have a very low incidence in this age group (5%). This finding challenges the validity of the assumption that some individuals have a congenital tendency for rotator cuff lesions, depending on their acromion types.
