Gluteal Region

Gluteal Region By Dr Samar

Boundaries       

SUPERIORLY iliac crest INFERIORLY Fold of buttock Gluteal muscles Thick layer of fascia skin

The skin 

Posterior and Anterior rami of spinal nerves

Fascia 



Superficial thick large amount of fat Deep fascia lata splits to in close gluteus maximus .then covers as single layer outer surface of medius . Becomes attached to iliac crest .on the lateral side forms iliotibeal tract which covers tensor fascia lata

Deep   



Piriformis Obturator internus Superior and inferior gemelli Quadratus femoris

Clinical  



Arteries   



Superior gluteal Inferior gluteal Trochanteric anastomosis Cruciate anastomosis

lymphatic 

Lateral group of superficial inguinal lymph nodes

The back of thigh   


