- Medial circumflex artery
- Lateral circumflex artery
These supply the femoral head.

Question 2

Answer 2

Knee extension

• Vastus Medius
• Vastus Intermedius
• Vasus Lateralis
• Rectus femoris

Question 3

Hamstrings

Answer 3

Knee flexion and hip extension

• Semimembranosus
• Semitendinosus
• Biceps femoris

Question 4

Abductors:
- Gluteus medius, medius and minimus

• Gracilis
• Sartorius

Question 5

Nerves in the hip

Answer 5

F.O.S.S.

Anterior: Femoral nerve
Medial: Obturator nerve
Posterior: Superior gluteal nerve
Lateral: Sciatic nerve

Question 6

Deformities of the hip on inspection

Answer 6

• Fixed flexion deformity: Thomas’s test
• External rotation
• Adduction: hip OA/shortened leg/protrusio acetabuli
• Abduction: NOF#/anterior dislocation of femoral head
