Galeazzi fracture-dislocations treated with open reduction and internal fixation show that distal radius fractures (Type I) are more prone to distal radioulnar joint instability than mid-shaft fractures (Type II). Early recognition and treatment of DRUJ instability are crucial.

Area of Science:

  • Orthopedic Surgery
  • Traumatology
  • Musculoskeletal Research

Background:

  • Galeazzi fracture-dislocations are complex injuries involving the radius and distal radioulnar joint (DRUJ).
  • Understanding fracture patterns is key to managing associated DRUJ instability.

Purpose of the Study:

  • To classify Galeazzi fracture-dislocations based on radial shaft fracture location.
  • To evaluate the incidence of intraoperative distal radioulnar joint instability.
  • To correlate fracture patterns with DRUJ instability and treatment outcomes.

Main Methods:

  • Retrospective analysis of 40 patients with Galeazzi fracture-dislocations treated surgically.
  • Classification of fractures into Type I (distal third) and Type II (middle third) based on proximity to the distal radius.

  • Assessment of intraoperative DRUJ stability after open reduction and internal fixation of the radial shaft fracture.
  • Management of DRUJ instability with wire transfixion or triangular fibrocartilage complex repair.

    • Main Results:

    • Twenty-two Type I fractures were identified, with 12 (54.5%) demonstrating intraoperative DRUJ instability.
    • Eighteen Type II fractures were identified, with only 1 (5.6%) showing intraoperative DRUJ instability.
    • Supplemental fixation or repair was required for 13 patients with DRUJ instability.

    Conclusions:

    • Fracture location significantly impacts the likelihood of associated distal radioulnar joint instability in Galeazzi injuries.
    • Type I fractures, located in the distal third of the radius, are strongly associated with DRUJ instability.
    • Prompt identification and management of DRUJ instability are essential to prevent long-term complications.
