1. Anatomy lecture 26-10-2008 Gluteal Region
Structures undercover of gluteus maximus

2. Gluteal surface of hip bone

3. Gluteus maximus ORIGIN Outer surface of Ilium, sacrum, coccyx
and sacro tuberous
Ligament.
Insertion:
Gluteal tuberosity of
Femur and iliotibial
Tract.
Nerve :
Inferior gluteal nerve
Action:
Extends and laterally
Rotates thigh.

4. GLUTEUS MAXIMUS

5. STRUCTURES UNDER GLUTEUS MAXIMUS

6. Gluteus medius Origin: Insertion: Nerve: Outer surface of ilium
greater trochanter
of femur.
Nerve:
Superior gluteal nerve
Action
Abduct thigh

7. Gluteus minimus Origin: Outer surface Of ilium. Insertion:
grearer trochanter
Nerve :
superior gluteal
Action
abduction

8. Piriformis muscle Comes through Greater sciatic notch. Action
(key muscle)
Comes through
Greater sciatic
notch.
Action
Laeral rotator of hip
joint
Ligaments:
Sacrotuberous
Sacrospinous

9. Iliotibial tract it is a deep fascia of the thigh
Most of gluteal maximus
Muscle fiber inserted
Into the iliotibial tract

10. PIRIFORMIS&SCIATIC NERVE

11. Sciatic nerve Formation Sacral plexus Root value L4-S3 of sacral
The thickest
nerve in the
body

12. Greater and lesser sciatic notch
Greater sciatic notch: lesser sciatic notch:
it provides the exit from the pelvis to the an intrance into the perineum from
gluteal region the gluteal region :
1- piriformis tendon of obturator internus
2- sciatic nerve muscle
3- post cutaneous nerve of the thigh nerve to obturator internus
4- sup and inf gluteal arteries and veins
5- pudendal nerve pudendal nerve
6- nerves to the obturator internus
and quadratus
7- internal pudendal artery and vein

13. Clinical anatomy I.M injection The gluteal region divide into
4 quadrant
and the injection
shoud be:
At the upper lateral
quadrant

14. POSTERIOR COMPARTMENT OF THE THIGH

15. HAM STRING MUSCLES 1.SEMI MEMBRANOSUS 2.SEMI TENDINOSUS
3.BICEPS FEMORIS
4.SCIATIC NERVE DIVIDES INTO TIBIAL AND THE COMMON PERONEAL NERVE
5.HAM STRING MUSCLES FLEXE THE KNEE JOINT AND EXTEND THE HIP JOINT

16. SCIATIC NERVE INJURY
PLEASE DON’T INJECT INTO THE SCIATIC NERVE AND SAVE ONE LOWER LIMB
PLEASE GIVE IM INJECTION INTO THE SUPERO LATERAL QUADRATANT OF THE GLUTIAL RIGION AND SAVE THE LIMB
