    Scaphoid fracture - Herbert classification

    Herbert classification of scaphoid fractures is primarily based on the distinction between stable fractures, which can be treated non-operatively, and unstable fractures in the acute setting.

    Type Description
    A: acute, stable A1: fracture of the tubercle
    A2: nondisplaced incomplete fracture in the waist
    B: acute, unstable B1: oblique fracture in the distal third
    B2: displaced or mobile fracture in the waist
    B3: fracture of the proximal pole
    B4: fracture with dislocation
    B5: comminuted fracture
    C: delayed union >6 weeks
    D: established non-union D1: fibrous
    D2: sclerotic
