- Up : insertion and belly of the gluteus medius

- Down: insertion of vastus lateralis

- Posteriorly:Insertion of Quadratus femoris with the belly of the gluteus maximus over the latter

-The horizontal crease is under the ischial tuberosity

-Inferior border is formed by insertions of the semitendinous muscle and the long belly of the biceps femoris in the ischial tuberosity

-Superiorly:formed by the lower border of the gluteus maximus

It arises in the median gluteal crease and follows a lateral curve, with a proximal concavity, no further than the union of the semitendinous muscle with the biceps femoris

2 hollows are located on either side of the medial sacral crest

-formed in their deepest part by the posterior superior iliac spine EIPS

-And medially by the multifidus muscle

In a more superficial plane,they are bounded by the lumbodorsal aponeurosis and inferiorly and laterally by the insertion of the gluteus maximus

 It is formed by

-2 lines arising in the proximal portion of the gluteal crease

-Directed towards the supragluteal fossettes

-These lines are formed by the insertion of the gluteus maximus in the lumbodorsal aponeurosis.They measure no more than 1/3 of the distance between the gluteal crease and the supragluteal fossettes

1.Lateral depression formed by the lateral border of the gluteus medius and vastus lateralis to the greater trochanter

2.Infragluteal fold created by the ischial tuberosity, the insertions of the semi tendinous muscle and long belly of the biceps femoris and the lower border of the gluteus maximus

3.Supragluteal fossettes (1 on either side) over the posterior superior iliac spine,created by the multifidus muscle, the lumbodorsal aponeurosis and the insertion of the gluteus maximus

4.V shaped crease arising in the proximal portion of the gluteal crease

5. Lumbar hyperlordosis contributes to beautiful buttocks. This hyperextension of the spine in the lumbosacral region is an ethnic feature ( black-mulato)
