Ultrasound tutorial – Imaging of the deltoid ligament

Deltoid Ligament Ultrasound – Technique and Findings


  • Lateral decubitus

Ultrasound probe for the Deltoid

  • Hockey stick probe
    • Easiest to position
    • Good resolution
  • High frequency linear probe
    • Larger field of view
    • Sometimes difficult to position optimally

Normal Appearance

  • Consistent thickness
  • Fascicular architecture with areas of the increased echogenicity (fat interspersed in the ligament)


  • Sprain
    • Hypoechoic
    • Thickened
    • Loss of fascicular architecture
  • Tear
    • Partial/full thickness
      • Fluid (anechoic) extends into the tear
