    Computed tomography (CT) accurately identifies sequestra in chronic osteomyelitis exacerbations. CT imaging also reveals foreign bodies and abscesses missed by plain radiographs, aiding surgical planning and treatment.

    Area of Science:

    • Radiology
    • Orthopedic Surgery
    • Infectious Disease

    Background:

    • Chronic osteomyelitis presents diagnostic challenges, particularly during acute exacerbations.
    • Plain radiographs can be equivocal for detecting small sequestra or in cases of diffuse bony sclerosis.
    • Accurate identification of bony sequestra, foreign bodies, and soft tissue abscesses is crucial for effective treatment.

    Purpose of the Study:

    • To evaluate the efficacy of computed tomography (CT) in identifying sequestra during acute exacerbations of chronic osteomyelitis.
    • To compare the diagnostic capabilities of CT with plain radiography in this patient population.
    • To assess the role of CT in guiding surgical management and treatment.

    Main Methods:

    • Retrospective review of CT examinations in 25 patients with acute exacerbations of chronic osteomyelitis.

  • Comparison of CT findings with plain radiographs for the identification of sequestra, foreign bodies, and soft tissue abscesses.
  • Correlation of imaging findings with surgical outcomes and treatment approaches.

    • Main Results:

    • CT correctly identified sequestra in 14 surgical patients, including cases where plain radiographs were equivocal.
    • CT detected small sequestra and diffuse bony sclerosis more effectively than plain radiographs.
    • CT revealed a foreign body and five soft tissue abscesses not evident on plain radiographs.
    • CT findings aided in guiding the operative approach and treatment for both positive and equivocal plain radiograph cases.

    Conclusions:

    • CT is a valuable tool for diagnosing sequestra in acute exacerbations of chronic osteomyelitis.
    • CT offers superior visualization of sequestra, foreign bodies, and soft tissue abscesses compared to plain radiography.
    • CT imaging significantly enhances surgical planning and treatment strategies for patients with chronic osteomyelitis.
