Computed tomography of septic joints.

M Rafii, H Firooznia, C Golimbu

    The Journal of Computed Tomography
    |January 1, 1985
    PubMed
    Summary

    Computed tomography (CT) is valuable for diagnosing septic arthritis, especially in deep axial joints. CT imaging aids in early detection of soft tissue swelling and bone erosion, guiding treatment and procedures.

    Area of Science:

    • Orthopedics
    • Radiology
    • Infectious Diseases

    Background:

    • Septic arthritis requires prompt diagnosis and treatment to prevent joint destruction.
    • Conventional radiography has limitations in visualizing early changes in septic arthritis, particularly in deep-seated or complex joints.

    Observation:

    • Computed tomography (CT) was retrospectively reviewed in 26 patients with suspected or known septic joints.
    • Eighteen patients (20 joints) were diagnosed with septic arthritis.

    Findings:

    • CT demonstrated soft tissue swelling in deep axial joints (hip, sacroiliac) as early as 36 hours after symptom onset.
    • CT identified osseous foci of infection and was superior to conventional radiology in detecting early articular bone erosion.
    • CT findings facilitated diagnosis, guided needle aspiration biopsies, and altered patient treatment in several cases.

    Implications:

    • CT is a valuable tool for evaluating acute septic arthritis of axial joints, including abscess formation and guiding percutaneous drainage.
    • CT can detect early articular bone erosion and medullary extension of osteomyelitis when conventional radiography is inconclusive.
    • Early and accurate diagnosis with CT can lead to improved patient outcomes and joint preservation.
