What is widening of the ankle mortise?
What is widening of the ankle mortise?
Widening of the ankle mortise that causes syndesmosis injury can also be the result of excessive or severe dorsiflexion. Normally, dorsiflexion causes the interosseous ligament to become taut.
What is the standard view for the ankle?
The standard radiographic analysis of the ankle includes three views: the anteroposterior (AP, also sometimes referred to as dorsoplantar or DP) view, the internal oblique (or mortise) view, and the direct lateral view.
What is mortise view of ankle?
The mortise view enables assessment for fractures and spacing of the entire joint surface, including that between the fibula and talus. The distance between the talus and either the fibula or tibia should be equal throughout the joint.
What does disruption of the ankle mortise mean?
When the mortise is disrupted by a fracture, the talus is free to move more than it should. This abnormal motion leads to focal pressure points which can be damaging.
What does a mortise view show?
The mortise view shows the entire mortise joint space between the talar dome and the medial malleolus, tibial plafond and lateral malleolus (Figures 1B and 2). On the AP view, the lateral malleolus overlaps and obscures the lateral joint space (Figure 1A).
Where is the syndesmosis?
ankle joint
The syndesmosis is a fibrous joint held together by ligaments. It’s located near the ankle joint, between the tibia, or shinbone, and the distal fibula, or outside leg bone. That’s why it’s also called the distal tibiofibular syndesmosis. It’s actually made up of several ligaments.
How is mortise view done?
The Mortise-view is an AP-view taken with a 15-25? endorotation of the foot. The technologist turns the foot inwards until the lateral malleolus is at the same height as the medial malleolus. This view visualizes both the lateral and medial joint spaces.
What does mortise mean in anatomy?
A depression, groove, or hole
A depression, groove, or hole into which another anatomical structure fits.
What would an MRI of the ankle show?
During a foot and ankle MRI procedure, pictures–also referred to as slices–of the ankle and foot will be produced. A radiologist will use the resulting images to identify any abnormalities. Such as tendon tears, inflammation, cartilage deterioration, or tumours.
