Perilabral sulcus

Last revised by Tim Luijkx on 5 Sep 2015

The perilabral sulcus is a physiological space between the acetabular labrum and capsule of the hip joint, which inserts next to the base of the labrum and is therefore intra-articular.

Superiorly the capsule's attachment is displaced from the labrum by a few millimeters and thus the sulcus is large and well-formed. Anteriorly and posteriorly the attachment of the capsule is much closer to the base of the labrum, and thus the perilabral sulcus is commensurately smaller.
