Thigh

1. Lacuna musculorum is bounded by medial portion of inguinal ligament anteriorly, pectineal ligament posteromedially, lacunar ligament medially, and iliopectinal arch posterolaterally
2. Posterior wall of femoral triangle consist of iliopsoas, pectineus, and adductor longus from lateral to medial side
3. Femoral hernia is more commonly seen in female due to their wider pelvis and femoral canal
4. Sartorius originates from anterior superior iliac spine and inserted to upper medial surface of tibia
5. Illiopsoas are innervated by tibial nerve branch of sciatic nerve and is responsible for the flexion of thigh on trunk
6. Muscles of the medial compartment are adductor longus, adductor brevis, adductor magnus and gracilis
7. All of the muscles of the medial compartment are innervated by obturator nerve
8. Sciatic nerve leaves pelvis through infrapiriform foramen to enter gluteal region, runs inferiorly medially deep to gluteus maximus
9. Superior and inferior gluteal nerve are branches from lumbar plexus
10. Obturator artery arises from internal iliac artery in the lesser pelvis, passes through the obturator canal where it divides into anterior and posterior branches
11. Contents of adductor canal are sciatic nerve, femoral artery, femoral vein and loose connective tissue
12. Femoral artery is distributed to all three muscle compartments of thigh by medial and lateral femoral circumflex artery and four perforating arteries of deep femoral artery
13. Sephanous nerve accompanies the femoral artery and femoral vein in the adductor canal
14. Femoral nerve enters the thigh anteriorly to the inguinal ligament and lateral to the femoral artery
15. All hamstring muscles are innervated by tibial nerve branch of sciatic nerve except short head of bicep femoris which is innervated by common peroneal nerve
16. A portion of adductor magnus is sometimes considered as part of hamstring muscle
17. Semitendinosus and semimembranosus rotates tibia laterally when knee is flexed meanwhile biceps femoris rotates the tibia medially
18. Intertrochanteric crest is found on the shaft of the femur
19. Patellar dislocation are more common in medial direction
20. The anterior, medial and posterior compartment of thigh muscles are divided by a septa which is formed by the deep fascia of the thigh
21. Pectineus helps in extension of thigh at the hip joint
22. Long head of biceps femoris is inserted to the linea aspera
23. Femoral artery and femoral vein pass through the adductor hiatus
24. Portions of small sephanous vein are harvested for heart bypass surgery
25. Coxa vara is when the head of femur is bent inwards meanwhile coxa valga is when the head of femur is bent outwards
