2. CHECKLIST FOR REPORTING
Bones: Screen on fatsat images for bone marrow
edema.
Joint: Screen for effusion and look at the joint capsule
for thickening.
Ligaments: Check the syndesmosis, the lateral and
medial ligaments.
Tendons: Check the tendons using the four quadrant
approach;
Flexors on the medial side.
Achilles tendon posteriorly.
Peroneal tendons on the lateral side.
Extensors on the anterior side.
3. BONES
Large joint made up of three bones:
The shin bone (tibia)
The thinner bone running next to the shin bone (fibula)
A foot bone that sits above the heel bone (talus)
4. In addition to the bony structures of the ankle - the
distal tibia, distal fibula and talus , the calcaneum,
navicular and cuboid bone as well as the three
cuneiforms and the bases of the metatarsal bones and
their alignment are assessed.
Osseous tumors, ankle fractures / stress fractures, bone
marrow changes are noted.
10. STIEDA PROCESS
• Elongated lateral tubercle of the
posterior process of the talus
• Related pathology
• Acute fracture
• Can be associated with posterior ankle
impingement syndrome from
impingement between the tibia and the
calcaneus, especially in plantar flexion.
In some symptomatic situations, it is
resected
11. LIGAMENTS
Four major ligamentous stabilizers
Medial collateral ligament
Lateral collateral ligament
Syndesmotic complex
Interosseous ligament
12. DELTOID LIGAMENT
Best evaluated in the coronal plane.
5 components.
Serves as a hammock for the talus.
Two parts , Superficial and deep.
Continuous with spring ligament.
