Summary

An initially overlooked transligamentary Chopart dislocation was diagnosed after severe foot trauma. Prompt diagnosis and treatment, including closed reduction and K-wire fixation, are crucial for managing this rare injury.

Fractures: Bone Repair

Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...

Area of Science:

  • Orthopedics
  • Trauma Surgery
  • Radiology

Background:

  • Chopart dislocations are rare injuries, often resulting from high-energy trauma.
  • Peritarsal dislocations constitute a small percentage of overall joint dislocations.
  • Initial radiographic assessment may miss subtle dislocations following significant foot trauma.

Observation:

  • A 55-year-old female presented with severe left foot swelling and deformity after a 4m fall.
  • Initial radiographs showed no fracture or dislocation, despite significant pain and deformity.
  • Delayed assessment revealed a transligamentary Chopart dislocation with talar head displacement, avulsed navicular fragments, and a depressed talar fracture.

Findings:

  • The case highlights the challenge of diagnosing transligamentary Chopart dislocations, especially when initially overlooked.

  • Successful treatment involved closed reduction, percutaneous K-wire fixation, and 8 weeks of immobilization.
  • Immediate reduction is emphasized to minimize potential complications.

    • Implications:

    • Clinicians must maintain a high index of suspicion for dislocations in high-energy foot trauma, even with initially negative radiographs.
    • Early and accurate diagnosis of Chopart dislocations is vital for optimal patient outcomes.
    • This case underscores the importance of thorough radiographic interpretation in foot and ankle injuries.
