The document discusses the gluteal muscles, which include the gluteus maximus, medius, and minimus, and their functions such as extension, abduction, and external rotation. It also covers conditions related to the gluteal region, including Trendelenburg's gait, sciatic nerve compression, sciatic hernias, trochanteric bursitis, and piriformis syndrome. The document emphasizes clinical anatomy and diagnostic tests associated with these conditions.

4. GLUTEAL
REGIONThe gluteal muscles are a
group of 3 muscles which make
up the buttocks: the Gluteus
maximus, gluteus medius, and
gluteus minimus. The 3
muscles originate from the ilium
& sacrum and insert on the
femur.
Functions:
1. Extension
2. Abduction
3. External rotation

8. Trendelburg’s Sign
Trendelenburg's sign is found in people with
weak or paralyzed abductor muscles of the hip,
namely gluteus medius and gluteus minimus
In A : Negative trendlenburg's
test . The hip abductors are
acting normally tilting the
pelvis upwards when the
opposite leg is raised from
the ground
In B : Positive
Trendelenburg's test . The hip
abductors are unable to

9. TRENDELBURG’S GAIT
The Trendelenburg gait pattern (or gluteus medius
lurch) is an abnormal gait (as with walking) caused
by weakness of the abductor muscles of the lower
limb, gluteus medius and gluteus minimus
Have patient stand on
one leg and assess if the
pelvis drops
(+) Trendelburg sign

11. SCIATIC HERNIA
A sciatic hernia is a rare type of hernia that develops in
the pelvic area through the lesser sciatic foramen. Unlike
other abdominal wall hernias, a swelling or bulge is
difficult to detect because of its position under the larger
gluteus muscle that covers the back of the pelvis.

12. SCIATIC NERVE
 Can be compressed at
lower border of gluteus
maximus by sitting on
bench
with a sharp
edge.(SLEEPING FOOT)
May be injured by
misplaced deep
intramusclular injections.
 To prevent this, the
injection is usually given
in the superolateral
quadrant.

14. TROCHANTERIC
BURSITIS
Trochanteric bursitis is characterized by painful
inflammation of the bursa located just superficial
to the greater trochanter of the femur

15. PIRIFORMIS
SYNDROME
When the sciatic nerve
divides in the pelvis, the
common peroneal nerve
may exit either:
below Piriformis
pierce piriformis
pass above piriformis
When it pierces piriformis, it
may be compressed by
contractions of this muscle.
This causes piriformis
