Diagnosis

Multifragmentary fractures of the radius

print

Multifragmentary fractures are the result of higher energy trauma, such as motor vehicle accidents, falls from heights, high velocity gunshot injuries, etc. More details about their clinical and radiographic examination see here .

Due to the injury of the interosseous membrane and often the lesions of the muscles, tendons, and skin these are considered serious injuries.

Options
1.  Segmental radial fracture
2.  Segmental radial fracture, ulnar fracture
3.  Fragmentary segmental radial fracture

1.  Segmental radial fracture

Segmental fractures of the radius are classified as AO/OTA 2R2C2.

They may be associated with a dislocation of the distal radioulnar joint (DRUJ), i.e., a Galeazzi injury. This is indicated with the qualifier (g). If the injury illustrated were associated with dislocation of the DRUJ, it would be 2R2C2(g).

Shortening at the radial fracture in combination with an intact ulna and a torn interosseous membrane, may also result in distal axial migration of the ulnar head at the distal radioulnar joint (DRUJ). Read more on the Essex-Lopresti lesion

2.  Segmental radial fracture, ulnar fracture

When both bones are fractured, they are classified independently according to the morphology of each fracture.

For example, the injury illustrated is AO/OTA 2R2C2 2U2A2.

3.  Fragmentary segmental radial fracture

When both bones are fractured, they are classified independently according to the morphology of each fracture.

For example, the injury illustrated is AO/OTA 2R2C3 2U2A2.
