  1. THIGH andFEMORAL TRIANGLE

  2. Femoral Triangle • Borders: Medial border of sartorius muscle. Medial border of adductor longus muscle. Inguinal ligament: From ASIS to pubic tubercle.

  3. Femoral Triangle • Contents (lateral to medial): Femoral Nerve (not in femoral sheath) Femoral Artery (in femoral sheath) Femoral Vein (in femoral sheath) Lymphatics (in femoral sheath)

  4. Femoral Triangle • Floor: Iliopsoas muscle. Pectineus muscle. Adductor longus muscle.

  5. Femoral Triangle • Femoral Sheath: Contents: Femoral artery and vein Lymphatics: In Femoral Canal

  6. Anterior Compartment of Thigh • Cutaneous Innervation: Femoral cutaneous nerves: Lateral Intermediate Medial Posterior

  7. Anterior Compartment of Thigh • Cribriform fascia and fossa ovalis: Opening for great saphenous vein: Empties into femoral vein. Drains medial side of dorsal venous arch. May be duplicated distal to the knee. Has 10 to 20 valves.

  8. Anterior Compartment of Thigh • Adductor Canal: Borders: Lateral: Vastus medialis muscle. Posterior: Adductor longus and magnus. Anteromedial: Sartorius muscle.

  9. Anterior Compartment of Thigh • Adductor Canal: Contents: Saphenous nerve: Termination of femoral nerve. Nerve to vastus medialis. Terminal part of obturator nerve. Terminal parts of femoral artery and vein. Deep lymph vessels.

  10. Anterior Compartment of Thigh • Muscles: Iliopsoas. Sartorius. Pectineus. Quadriceps: Rectus femoris. Vastus lateralis. Vastus intermedius. Vastus medialis.

  11. Anterior Compartment of Thigh • Blood Supply: Femoral Artery: Superficial circumflex iliac. Superficial epigastric. Superficial external pudendal. Deep external pudendal. Descending genicular.

  12. Anterior Compartment of Thigh Blood Supply: Femoral Artery: Deep femoral (profunda femoris) Lateral femoral circumflex. Medial femoral circumflex. Perforating arteries: Three plus termination of deep femoral.

  13. Anterior Compartment of Thigh • Innervation: Femoral Nerve: • Action: Hip flexion. Rectus femoris. Sartorius. Knee extension.

  14. Medial Compartment of Thigh • Muscles: Gracilis. Adductor longus. Adductor brevis. Adductor magnus. Obturator externus.

  15. Medial Compartment of Thigh • Blood Supply: Obturator artery: Branch of internal iliac artery. • Innervation: Obturator nerve. Tibial nerve: To hamstring portion of adductor magnus. • Action: Adduction

  16. Posterior Compartment of Thigh • Muscles: Hamstrings: Biceps femoris: Long head. Short head. Semimembranosus. Semitendinosus. • Adductor Hiatus

  17. Posterior Compartment of Thigh • Innervation: Common peroneal nerve: To biceps femoris brevis. Tibial nerve: • Vascular Supply: Perforating arteries (from profunda femoris) • Action: Hip extension. Knee flexion.
