Gluteal region

As Regio glutaea (also Regio glutea , "buttocks region") is the area of ​​the buttocks in topographical anatomy . In animals, this region is also called " croup ".

The boundaries of the gluteal region are:

• cranial (towards the head) the iliac crest of the iliac bone
• ventrally (ventrally) and laterally (laterally) the iliac spine of the iliac bone and the anterior border of the tensor fasciae latae muscle
• caudally ( towards the tail) the gluteal groove ( sulcus glutaeus ) and
• medially (towards the middle) the anal groove ( crena analis ).

The musculus gluteus maximus is dominant . The gluteal groove is stabilized by a fascia with fixation on the ischial tuberosity ( tuber ischiadicum ). Under the gluteus maximus muscle lie the gluteus medius muscle and gluteus minimus muscle . Their muscle boxes are structured by the gluteal fascia ( Fascia glutaea ), which prevents the spread of inflammatory processes.

Under the gluteus maximus muscle lies the subgluteal space , which is filled with fat and connective tissue . Downwards the Spatium is subglutaeum of the outer rollers of the hip joint ( articulatio coxae ) to form the greater sciatic foramen and minus limited to the inner basin. Important nerves for the buttocks and thighs run in this 1–2 cm gap . Through this opening, inflammation can spread far distally to the popliteal region of the knee .

The skin innervation of the gluteal region is done by the Nervi clunium .
