Adams furrow is a groove on the outer surface of the skull, located transversely in the area of the coronal suture. Described in 1850 by the English surgeon William Adams (1820-1900).
Adams's groove is a shallow groove 5-7 cm long, running obliquely outward from behind and somewhat posteriorly parallel to the coronal suture. Formed as a result of partial fusion of the coronal suture.
The presence of Adams' groove indicates incomplete fusion of the coronal suture, which may indicate delayed ossification of the skull. Therefore, this anatomical feature is more common in children and adolescents. As Adams ages, the groove usually disappears.
