Distal Radius Fractures

  • Fractures of the distal radius are among the most common of all orthopaedic injuries accounting for nearly 1/6 of all fractures
  • Bimodal age distribution exists, one peak in early adolescence, second in the older age.

    Mechanism

    • FOOSH
    • Wrist at 40 - 90° dorsi-flexion usually produces fractures of the distal radius
    • Scaphoid fractures occur at about 97°

    Examination

    • Check for other fractures
    • Neurovascular assessment, particularly median nerve compression
  • Check for other fractures

    X-ray

    • PA/Lateral
    • CT for intra-articular fractures
  • PA/Lateral
  • CT for intra-articular fractures

    Check for

    • Loss of radial height (>5mm)
    • Loss of radial inclination (Normal 20-25°)
    • Dorsal tilt (Normal 10° volar)
    • Radial width
    • Comminution
    • Ulnar fracture
  • Loss of radial height (>5mm)
  • Loss of radial inclination (Normal 20-25°)
  • Dorsal tilt (Normal 10° volar)
  • Radial width
  • Comminution
  • Ulnar fracture

    NB Axial or rotational malalignment can produce DRUJ problems
