Group V
Displaced fractures of the lesser tuberosity.
Group VI
Fracture-dislocations.



Radial head fractures: Hotchkiss modification of
Mason’s classification
Type 1
Small vertical split with minimal displacement (2 mm).
Type 2
Displaced single fragment fracture (2 mm), usually distally.
Type 3
Highly comminuted fractures that cannot be internally fixated.


Fractures of the radius and ulna
Monteggia fracture-dislocation
Fracture of the ulna associated with dislocation of the radial head.

Galeazzi fracture-dislocation
