Acetabular notch
Incisura acetabuli
Definition
Acetabular notch is a small gap located inferiorly within the margin of the hip bone’s acetabulum. This gap is spanned by the transverse acetabular ligament.
When the transverse acetabular ligament crosses the acetabular notch, it forms a slight space between the ligament and the bony notch, enabling the passage of nutrient vessels into the hip joint.
