Summary
This summary is machine-generated.

CT arthrography offers superior visualization of the labrum glenoidale, aiding in the diagnosis of shoulder instability. This technique is more reliable than MRI and less invasive than arthroscopy for labral lesion assessment.

Area of Science:

  • Orthopedic imaging
  • Diagnostic radiology
  • Sports medicine

Background:

  • The glenoid labrum is crucial for shoulder joint stability.
  • Advancements in imaging have improved labral assessment.
  • Diagnostic errors can arise from morphological variations.

Purpose of the Study:

  • To evaluate the effectiveness of CT arthrography for assessing the labrum glenoidale.
  • To compare CT arthrography with other imaging modalities like MRI and arthroscopy.
  • To identify common sites and causes of labral lesions.

Main Methods:

  • Review of CT arthrography, MRI, and arthroscopy for labrum glenoidale assessment.
  • Analysis of lesion sites including anteroinferior, posterior, SLAP, and anterosuperior.

  • Comparison of imaging techniques based on definition, invasiveness, and cost.

    • Main Results:

    • CT arthrography provides superior definition and fine sections for labral assessment.
    • Morphological variations of the labrum and glenohumeral ligaments are common causes of diagnostic errors.
    • SLAP lesions, particularly types I and II, are challenging to demonstrate and interpret.

    Conclusions:

    • CT arthrography is the most reliable technique for evaluating the labrum glenoidale.
    • It is indicated for painful, unstable shoulders with normal or doubtful glenoidal margins.
    • CT arthrography is preferred over arthroscopy due to lower invasiveness and cost.
