From the Guidelines

Over-distraction in an external fixator can lead to complications such as finger stiffness.

Complications of Over-Distraction

  • The most significant complication of over-distraction is finger stiffness, which can have a significant impact on patient outcomes 1.
  • While the evidence is inconclusive, it is generally agreed that limiting the duration of fixation can help to minimize complications 1.
  • Prolonged external fixation has been associated with poorer outcomes in some studies, although the evidence is not strong enough to define a specific duration for immobilization 1.
  • It is essential to balance the need for adequate fixation with the risk of complications, and individualized treatment plans should be developed to minimize the risk of over-distraction and associated complications.
  • The use of validated patient outcome scores is crucial in evaluating the effectiveness of treatment and identifying potential complications 1.

From the Research

Complications of Over-Distraction in External Fixation

  • Excess distraction can lead to adverse effects, including potential complications and a negative impact on outcome 2
  • Overdistraction of bone fragments can result in poor outcomes, emphasizing the importance of careful management to prevent this issue 3
  • The use of external fixation, particularly with overdistraction, may increase the risk of post-operative complications, such as motion loss, infection, and hardware-related issues 4
  • Overdistraction can be mitigated with additional stabilization techniques, allowing for immediate reduction of overdistraction and minimizing potential complications 5
  • Specific complications associated with overdistraction in external fixation include:
    • Motion loss
    • Infection
    • Hardware-related issues
    • Algodystrophy
    • Nerve irritation
    • Skin lesions
    • Deep vein thrombosis
    • Pulmonary embolism
    • Recurrent ligamentous laxity
    • Need for additional surgery 2, 3, 4, 5
