14. Muscles of anterior compartment of thigh

15. Definition: pyramidal space in front of upper 1/3 of thigh.
Femoral Triangle
Definition: pyramidal space in front of upper 1/3 of thigh.
Boundaries:
Sup (base): inguinal ligament (lower border of external oblique, extending from ASIS to pubic tubercle).
Lat: sartorious (med border).
Med: adductor longus (med border).
Roof: skin, superficial fascia & deep fascia.
Floor: (med to lat): adductor longus, pectineus, psoas major & iliacus.

16. contents
1-Femoral sheath: fascial sheath surrounding upper part of femoral vessels. It contains:
Med: femoral canal: conical compartment to allow expansion of femoral V.
Intermediate: femoral V.
Lat: femoral A and femoral branch of genitofemoral N.
2-Femoral N.
3-Deep inguinal Lymph nodes.

18. Adductor (subsartorial) canal
Definition: tunnel in the middle 1/3 of thigh.
Begins at the apex of femoral triangle.
Ends at the opening of adductor magnus (becomes continuous with popliteal fossa).
Boundaries:
Anterolateral: vastus medialis.
Anteromedial (roof): fibrous roof and sartorious.
Post (floor): adductor longus & magnus.

19. contents
1-Femoral A.
2-Femoral V.
3-Saphenous N: enters the canal through upper end and leaves it behind Sartorius, pierces deep fascia to become subcutaneous in the leg.
4-N to vastus medialis: passes through upper end to vastus medialis.
5-Descending genicular A (of femoral).

20. Femoral nerve
Root value: Lumbar plexus, L2,3,4 (ant rami, post division).
Course & relations:
Descends between psoas major & iliacus.
Passes deep to inguinal ligament to enter femoral triangle.
End: 4 cm (1½ inches) below inguinal ligament as muscular & cutaneous branches.

21. Branches To hip joint. To knee joint.
Muscular: iliacus (in abdomen), pectineus, sartorious & quadriceps.
Articular:
To hip joint.
To knee joint.

22. Cutaneous Med cutaneous N of thigh: skin of med side of thigh.
Intermediate cutaneous N of thigh: skin of front of thigh.
Saphenous N:
Descends in femoral triangle → adductor canal → passes behind Sartorius → pierces deep fascia & becomes subcutaneous.
Supplies the skin of med side of leg & foot.
Cutaneous

23. Injury of femoral N (in the thigh)
Motor: paralysis of quadriceps → loss of knee extension.
Sensory: loss of sensation of the ant & med sides of thigh & med side of leg & foot.
