Injuries to the elbow collateral ligaments, often from repetitive stress, are best visualized with magnetic resonance imaging (MRI). Contrast-enhanced MRI improves the identification of ligament damage and abnormalities.

Area of Science:

  • Orthopedics
  • Radiology
  • Sports Medicine

Background:

  • Elbow collateral ligaments provide stability against varus and valgus forces.
  • Injuries can be acute or chronic, often resulting from repetitive microtrauma.
  • Elbow overuse injuries are common, making the joint the second most frequently affected by overuse.

Purpose of the Study:

  • To demonstrate normal anatomy of the elbow collateral ligaments.
  • To illustrate collateral ligament pathology using magnetic resonance imaging (MRI).
  • To compare unenhanced and contrast-enhanced MRI for visualizing ligament abnormalities.

Main Methods:

  • Review of magnetic resonance imaging (MRI) techniques for elbow collateral ligaments.
  • Demonstration of normal ligamentous anatomy on MRI.

  • Presentation of pathological findings in unenhanced and contrast-enhanced MR images.

    • Main Results:

    • Magnetic resonance imaging (MRI) is the optimal modality for visualizing elbow collateral ligaments.
    • Contrast injection enhances the identification of these structures and associated pathologies.
    • Specific examples of collateral ligament injuries are shown in both unenhanced and enhanced MR images.

    Conclusions:

    • MRI is essential for diagnosing elbow collateral ligament injuries.
    • Contrast-enhanced MRI offers superior visualization for detecting ligament pathology.
    • Understanding normal and abnormal MRI findings is crucial for accurate diagnosis and treatment planning.
