2.
- Articular and Muscular
- Sensation
- External rotation and posterior thigh, foot
Femoral Nerve

Q
Avascular Necrosis
Interruption of Vascular supply of the femoral head
Risk factors?
A
- Fracture
- Steroids
- Coagulopathy
- Dislocation
- ETOH
- Sickle Cell

8
Q
Avascular Necrosis of femoral head
- Bilateral or unilateral?
- Prognosis?
- Tx? 2
