Diagnosing aching shoulder pain from rotator cuff tears can be challenging. Real-time ultrasound (US) offers high accuracy (95%), with magnetic resonance (MR) imaging as a valuable alternative for complex cases.

Area of Science:

  • Orthopedics
  • Radiology
  • Musculoskeletal Imaging

Background:

  • Aching shoulder pain is often difficult to diagnose, potentially impairing surgical outcomes due to delayed detection of rotator cuff lesions.
  • Long-standing rotator cuff lesions can lead to tendon adhesions and muscle atrophy, complicating diagnosis and treatment.

Purpose of the Study:

  • To evaluate the diagnostic accuracy of arthrography, real-time ultrasound (US), and magnetic resonance (MR) imaging for aching shoulder.
  • To compare the effectiveness of these imaging modalities in detecting rotator cuff tears and associated pathologies.

Main Methods:

  • Retrospective analysis of 25 patients with aching shoulder pain.
  • Imaging techniques included arthrography, real-time US (5 MHz linear probe), and high-field (1.5 T) MR imaging.

  • Comparison of diagnostic findings for rotator cuff tears and periarticular pathologies.

    • Main Results:

    • Arthrography identified cuff tears in 14/25 patients.
    • US detected tears in 14/25 (95% accuracy, 1 false negative) and identified other pathologies.
    • MR imaging revealed cuff lesions in 16/25 patients, including a partial tear missed by arthrography, and visualized periarticular inflammation.

    Conclusions:

    • Real-time US demonstrates high diagnostic accuracy (95%) for rotator cuff tears in patients with aching shoulders.
    • MR imaging is a valuable alternative to arthrography for equivocal US findings, offering detailed visualization of cuff lesions and associated inflammatory conditions.
    • Early diagnosis of rotator cuff lesions and related pathologies is crucial for effective management of aching shoulder pain.
