    Study Notes

    Ankle Anatomy

    • The ankle joint is a synovial hinge joint (dorsiflexion/plantar flexion).
    • The mortise joint is a gliding joint between the distal ends of the tibia and fibula and the proximal end of the talus.
    • The ankle mortise is formed by three borders:
      • Articular facet of the lateral malleolus
      • Articular facet of the medial malleolus
      • Inferior articular surface of the tibia and superior margin of the talus
    • The ankle includes the tibiotalar joint, subtalar joint, and distal tibiofibular joint (syndesmosis).

    Ankle Ligaments

    • The ankle has three main sets of ligaments:
      • Medial: Deltoid ligament
      • Lateral: PTFL, ATFL, and CFL
      • Syndesmotic ligament
    • Achilles injuries often occur during sports.

    Ankle Fat Pads

    • Kager fat pads are normally lucent on lateral radiographs.
    • Obliteration or distortion of the fat pad borders may indicate posterior ankle pathology.

    Ankle Imaging

    • Potential indications for ankle imaging include trauma, pain, lumps, swelling, foreign body, deformity, loss of function, reduced range of motion, and infections.
    • For ankle radiographs, remove shoes, socks, and jewelry (anklets, toe rings, etc.).
    • Standard ankle radiographs include:
      • AP ankle
      • AP mortise oblique ankle
      • Lateral ankle
      • 45-degree oblique ankle
      • Horizontal beam lateral ankle

    Ankle Radiographic Projections

    AP Ankle

    • The central ray should be directed midway between the medial and lateral malleoli at the level of the malleoli.
    • The cassette should be parallel to the long axis of the ankle.
    • The foot should be dorsiflexed to place the long axis of the foot in a vertical position.

    AP Mortise Oblique Ankle

    • The central ray should be directed midway between the medial and lateral malleoli at the level of the malleoli.
    • The cassette should be parallel to the long axis of the ankle.
    • From the AP position, rotate the entire lower leg 15-20 degrees internally, placing the intermalleolar plane parallel to the image receptor.

    Lateral Ankle

    • The central ray should be directed over the medial malleolus.
    • The cassette should be parallel to the long axis of the ankle.
    • Roll the patient laterally onto the affected side.
