Anatomical terminology

The Transverse Acetabular Ligament is a ligament in the hip joint that bridges the acetabular notch. It is a strong, pyramidal band of fibres, completing the acetabular labrum, which is deficient at the notch.

Structure

The transverse acetabular ligament is a strong, pyramidal band of fibres, completing the acetabular labrum, which is deficient at the notch. It is attached by one end to the brim of the notch, and by the other to the bottom of the notch, converting the latter into a foramen through which vessels and nerves enter the joint.

Function

The transverse acetabular ligament serves to complete the acetabular socket and protect the vessels and nerves that pass through the acetabular notch.

Clinical significance

Injury to the transverse acetabular ligament can result in hip instability and pain.
