Exploration of gluteal region and hip
Deep relations of gluteus maximus, left posterolateral view
The gluteus maximus has been divided transversely across its midportion and the ends of the muscle have been reflected medially and laterally. The medial part of the lamina of fascia lata underlying the muscle has been removed. The gluteus medius and piriformis muscles have been exposed together with the sciatic nerve and branches of the gluteal vessels and nerves. The medial area of this dissection is shown in detail in the following view.
1 . Superior gluteal artery (accompanied by superior gluteal vein)
2 . Quadratus lumborum muscle
3 . Iliac crest
4 . Gluteus medius (partially covered by fascia lata)
5 . Upper pointer: Inferior gluteal nerve Lower pointer: piriform muscle
6 . Fascia lata (deep to gluteus maximus)
7 . Gluteus maximus muscle (divided and reflected)
8 . Location of greater trochanter
9 . Inferior cluneal nerve (cut off)
10 . Posterior femoral cutaneous nerve
11 . Iliotibial tract
12 . Biceps femoris muscle
13 . Vertebral spinous process of L. IV
14 . Sciatic nerve
15 . Artery supplying sciatic nerve
16 . Ischial tuberosity
17 . Perineal branch of posterior femoral cutaneous nerve
