Diagnosis

Simple fracture of the radius

print

Simple fractures are often the result of indirect mechanisms, such as a fall onto an outstretched hand, sporting activities, etc. More details about their clinical and radiographic examination see here .

Simple radial fractures are classified by AO/OTA as 2R2A. They are further subdivided based on the direction of the radial fracture line.

If there is a concomitant involvement of the distal radioulnar joint (Galeazzi), this is indicated with the qualifier (g).

Options
1.  Oblique and spiral fractures
2.  Transverse
3.  With dislocation of distal radioulnar joint (Galeazzi)

1.  Oblique and spiral fractures

These fractures include:

  • Spiral fractures of the radius (AO/OTA 2R2A1)
  • Oblique fractures of the radius (AO/OTA 2R2A2)

2.  Transverse

22-A2.2

22-A2.2

Transverse and short oblique (< 30°) fractures of the radius are classified as AO/OTA 2R2A3.

3.  With dislocation of distal radioulnar joint (Galeazzi)

In a Galeazzi fracture-dislocation the displaced radial shaft fracture is associated with a dislocation of the ulnar head at the distal radioulnar joint (DRUJ).

These are classified by AO/OTA, according to the morphology of the radial fracture, with qualifier (g). For example, the illustration shows a 2R2A2(g).

Most often, the dislocation of the ulnar head is posterior, but very seldom it is anterior (as shown in the x-ray).
