  • Figure 1
    Lateral radiograph of left foot

    Lateral radiograph of left foot shows a radiolucency traversing the anterosuperior calcaneal process representing a fracture (arrowhead).

     
    Area of Interest: Bones; Imaging Technique: Plain radiographic studies; Procedure: Diagnostic procedure; Special Focus: Trauma;
     
     
  • Figure 2
    Medial oblique radiograph

    Medial oblique radiograph reveals a broad-based faint radiolucent line (arrowhead) at the anterosuperior calcaneal process.

     
    Area of Interest: Bones; Imaging Technique: Digital radiography; Procedure: Diagnostic procedure; Special Focus: Trauma;
     
     
  • Figure 3
    Sagittal T1-weighted MR

    Sagittal T1-weighted MR image depicts slightly irregular interface (arrow) traversing the base of the anterosuperior calcaneal process. The surrounding low signal intensity area indicates bone marrow oedema.

     
    Area of Interest: Bones; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Trauma;
     
     
  • Figure 4
    Axial T1-weighted MR

    Axial T1-weighted MR image better reveals the broad-based triangular shape of the fragment (arrow) outlined by a hypointense line representing the fracture. Mild hypointensity involving the fragment and adjacent bone...

  • Figure 5
    Sagittal STIR MR

    Sagittal STIR MR image shows separate fragment (arrow) at the anterosuperior calcaneal process. Bone marrow oedema involving the anterior aspect of the calcaneus and small fluid collection at the talocalcaneal and...
