Dynamic external fixators offer a promising alternative for treating distal radius fractures, achieving good to excellent functional and anatomical outcomes. Adjunctive Kirschner wires aid early mobilization in unstable cases.

Area of Science:

  • Orthopedics
  • Traumatology
  • Surgical Innovation

Background:

  • Distal radius fractures, particularly comminuted and intraarticular types, present significant treatment challenges.
  • Optimal management aims to restore anatomical alignment and functional wrist mobility.

Purpose of the Study:

  • To evaluate the efficacy and outcomes of dynamic external fixator treatment for closed comminuted distal radius fractures.
  • To assess the role of adjunctive Kirschner wires in managing unstable fracture patterns.

Main Methods:

  • Thirty adult patients with distal radius fractures underwent closed reduction and immobilization with a dynamic external fixator.
  • Thirteen patients with unstable fractures received additional Kirschner wires.
  • A phased approach involving rigid fixation followed by controlled mobilization was employed.

Main Results:

  • Excellent or good functional outcomes were achieved in 87% of patients.
  • Excellent or good anatomical results were observed in 97% of patients.
  • Minimal loss of reduction and manageable complications were reported.

Conclusions:

  • Dynamic external fixation is an effective treatment for comminuted distal radius fractures, yielding favorable functional and anatomical results.
  • The use of Kirschner wires is recommended for unstable fractures to facilitate early wrist mobilization.
  • This method presents a viable alternative for complex distal radius fracture management.
