- Mason-Johnston classification of radial head fractures
The Mason classification ( sometimes known as Mason-Johnston classification) is used to classify radial head fractures and is useful when assessing further treatment options 1,2.
Classification
type I: non-displaced radial head fractures (or small marginal fractures), also known as a "chisel" fracture
type II: partial articular fractures with displacement (>2 mm)
-
type III: comminuted fractures involving the entire radial head
IIIa: fracture of the entire radial neck, with the head, completely displaced from the shaft
IIIb: articular fracture involving the entire head, consisting of more than two large fragments
IIIc: fracture with a tilted and impacted articular segment
type IV: fracture of the radial head with dislocation of the elbow joint
In general type I injuries can be treated conservatively whereas type II injuries require open reduction and internal fixation (ORIF). Type III injuries often require early complete excision of the radial head 2.
