Scaphoid fracture which area has maximum chances of AVN/Non-union/Malunion:- 
Select and explain. 
A. Proximal 1/3, B. Middle 1/3, C. Distal 1/3, D. Scaphoid Tubercle fractrue
A: Proximal 1/3
Answer: A: Proximal 1/3 
Explanation: * Scaphoid has retrograded blood supply (distal to proximal) hence the distal pole is highly vascularized.* Due to fracture at the waist of scaphoid, blood supply to proximal pole is compromised. Hence proximal 1/3rd has the maximum chance to undergo AVN/non-union or malunion.
