In 1985, Andrews et al first described superior labral lesions primarily lo
cated in the anterosuperior aspect of the labrum in 73 athletes who throw o
verhead. Subsequently, Snyder et al coined the term superior labrum anterio
r to posterior lesion by identifying and classifying injury to the labrum t
hat originated posteriorly, and extended anteriorly. During the past 15 yea
rs, these superior labral injuries have been the source of approximately 70
peer-reviewed publications in the English language literature. Substantial
debate continues, however, with reference to the pathogenesis, diagnosis,
and treatment of these lesions. The current review defines the anatomy, pos
sible etiologies, diagnosis, and treatment of injuries to the superior labr
um.
