Scaphoid fracture which area has maximum chances of AVN/Non-union/Malunion:-: (A) Proximal 1/3, (B) Middle 1/3, (C) Distal 1/3, (D) Scaphoid Tubercle fractrue
Answer is A. * 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.
