Mayo classification of scaphoid fractures

Mayo classification of scaphoid fractures divides them into three types according to the anatomic location of the fracture line:

  • middle (70%)
  • distal (20%)
  • proximal (10%)

Fractures of the distal third are further divided into distal articular surface and distal tubercle fractures:

  • distal tubercle third fracture
  • distal articular surface fracture
  • distal third fracture
  • middle third fracture
  • proximal third fracture

The location of the fracture has important implications on the risk of AVN and, therefore, management.
