Oblique simple fracture of the ulna

These fractures include:

  • Spiral fractures of the ulna (AO/OTA 2U2A1)
  • Oblique fractures of the ulna (AO/OTA 2U2A2)

Simple fractures are likely to occur at the middle zone of the diaphysis, where the ulna has thick cortices, a narrow medullary canal, and an approximately triangular cross-section.

Simple fractures are often the result of indirect mechanisms, such as a fall onto an outstretched hand, sporting activities, etc. Surgical management of ulnar fractures is generally more straightforward because of the architecture of the ulna and its superficial location.
