2. Anatomic illustration of a right hip demonstrating the anatomic attachment sites of the labrum, hip joint capsule, direct and indirect heads of the rectus femoris muscle, and the iliocapsularis muscle.
Anatomic illustration of a right hip demonstrating the anatomic attachment sites of the labrum, hip joint capsule, direct and indirect heads of the rectus femoris muscle, and the iliocapsularis muscle. AIIS = anterior inferior iliac spine. Mean measurements of the footprint area of the AIIS superior and inferior facets and the width of the AIIS ridge are presented with 95% confidence intervals shown in brackets.

5. Anatomic illustration of a right hip showing the locations of the anterior labral sulcus (psoas-u), stellate crease, hip joint capsule, and the rectus femoris muscle in relation to their clock-face locations, with 95% confidence intervals shown in brackets.
Anatomic illustration of a right hip showing the locations of the anterior labral sulcus (psoas-u), stellate crease, hip joint capsule, and the rectus femoris muscle in relation to their clock-face locations, with 95% confidence intervals shown in brackets. The center of the psoas-u is located at the 3:30 position, in comparison with the superior tip, located at 3:00.

6. Dissection photo of a right hip showing the locations of the anterior labral sulcus (psoas-u), stellate crease, hip joint capsule, and the rectus femoris muscle in relation to their clock-face positions, with 95% confidence intervals shown in brackets.
Dissection photo of a right hip showing the locations of the anterior labral sulcus (psoas-u), stellate crease, hip joint capsule, and the rectus femoris muscle in relation to their clock-face positions, with 95% confidence intervals shown in brackets. The center of the psoas-u is located at the 3:30 position, in comparison with the superior tip, located at 3:00. The joint capsule was retracted utilizing a surgical grasper in order to better visualize the anterior labral sulcus.
