DEEP FASCIA OF THIGH

Regional Anatomy: Lower Limb

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

2. OBJECTIVE What is Fascia L ata ? 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. IMPORTANCE OF ILIOTIBIAL TRACT Insertion of 2 muscles(upper part) 3/4 part of the Gluteus M aximus Tensor Fasciae L atae .

7. The iliotibial tract stabilizes the K nee Extension & Partial flexion Constantly during walking and running

8. In leaning forwards With slightly flexed knee M ain support of the knee against gravity .

9. Saphenous Opening O val 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 .

10. 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.

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

12. Intermuscular Septa

13. 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.
