perilabral sulcus
Magnetic
resonance arthrography of the hip: technique and spectrum of findings in younger patients. Normal hip joint. Coronal fat-saturated T1-weighted arthro-MR image demonstrates a perilabral recess (white arrow). The superior labrum has a normal triangular shape and an homogeneous low signal (white arrowhead)
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.
