Regional Anatomy: Lower Limb

1. DEEP FASCIA
Dr. Heta Patel (PT)
Assistant Professor,
ARIP,
CHARUSAT.

2. OBJECTIVE
• What is Fascia Lata?
• How to recognize it?
• Brief about its modifications.
• Opening in Fascia Lata.
• Septa of Thigh.
• Recalling the Lecture.

3. What is Fascia Lata?
• tough fibrous sheath
• envelops the whole of the thigh.

4. • Attatchments:
• Superiorly
• Anteriorly
• Laterally
• Posteriorly
• Medially
• Inferiorly

5. Modifications of Fascia Lata
• Tensor Fascia Lata: The fascia lata is thickened
laterally where it forms a 5 cm wide band
called the iliotibial tract.

6. SUPERIORLY
Superficial
lamina
Tubercle of the
iliac crest
Deep lamina
Capsule of the
hip joint

7. Inferiorly
anterior surface
of the lateral
condyle of the
tibia.
smooth area

8. IMPORTANCE OF ILIOTIBIAL
TRACT
Insertion of 2 muscles(upper part)
3/4 part of the Gluteus Maximus
Tensor Fasciae Latae.

9. The iliotibial tract stabilizes the Knee
Extension & Partial flexion
Constantly during walking and running

10. In leaning forwards
With slightly flexed knee
Main support of the knee against gravity.

11. Saphenous Opening
• Oval opening in the fascia lata.
• Site : The centre of the opening is 4 cm below
and 4 cm lateral to the pubic tubercle.
• Size : It is about 2.5 cm long and 2 cm broad
with its long axis directed downwards and
laterally.

12. • Margin: The opening has a sharp crescentic
lateral margin or falciform margin which lies
in front of the femoral sheath.
• The medial margin of the opening lies at a
deeper level. It is formed by the fascia
overlying the pectineus.
• The fascia passes behind the femoral sheath.

13. • Overlying Fascia: The saphenous opening is
closed by the cribriform fascia which covers
the opening.

14. Intermuscular Septa

15. CLINICAL ANATOMY
• Attached to the inguinal ligament
• Extension of the thighs pulls the abdominal
wall downwards and makes it tense.
• To relax the abdomen fully for palpation by an
examining physician, the patient is asked to
draw the legs up.
• This overcomes the pull of the fascia lata on
the abdominal wall.
