fracture of the ulna is the second most common single bone forearm
fracture, generally resulting from blunt forearm trauma. The junction of
the middle and distal thirds of the ulna is mechanically the most susceptible
to fracture because of its cross sectional geometry at that point (Hsu).
Because this is usually a low energy injury, it may be treated in a cast

displaced fractures or those failing closed treatment. Isolated radial
shaft fractures are less common, more often presenting as a Galeazzi
