Exploration of gluteal region and hip

Relation of gluteus minimus to capsule of hip joint; nerve to hip joint

The gluteus minimus has been reflected downward to reveal the capsule of the hip joint. A branch of the superior gluteal nerve to the capsule is stretched around the retracted muscle.

1. Area of origin of Gluteus maximus muscle
2. Area of origin of Gluteus medius muscle
3. Superior gluteal artery
4. Location of Anterior gluteal line
5. Area of origin of Gluteus minimus muscle
6. Acetabular margin (visible through capsule of hip joint)
7. Reflected head of origin of Rectus femoris muscle
8. Upper pointer: Branch of Superior gluteal nerve to hip joint capsule Lower pointer: Hip articular capsule
9. Gluteus minimus muscle (reflected)
10. Iliotibial tract (covering tensor fasciae latae muscle)
11. Posterior inferior iliac spine
12. Margin of Greater sciatic foramen
13. Inferior gluteal artery
14. Sacrotuberous ligament
15. Piriform muscle (divided)
16. Upper pointer: Obturator internus muscle Lower pointer: Sciatic nerve
17. Ischial tuberosity
18. Biceps femoris muscle (origin of long head)
19. Quadratus femoris muscle
20. Nerve to tensor fasciae latae muscle (cut off)
