What is the indication for the stress ap of the ankle joint?
Indications. In intermediate ankle injuries that have no syndesmotic widening on x-ray — yet a high suspicion of injury — will warrant a stress view to demonstrate dynamic widening of the ankle joint 1.
What is ankle mortise disruption?
Disruption of the medial deltoid ligament also causes instability. The proximal fibula may also be fractured (called a Maisonneuve fracture) when the medial malleolus is fractured, the ankle mortise (the joint between the tibia and the talus) is open, and the distal fibula is not fractured.
What is mortise view of ankle?
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 are stress views?
Stress views are additional X-ray projections that demonstrate indirectly the amount of joint cartilage left. They are to be taken with the knee bent 15 degrees, the thigh supported by a thigh rest.
How do you know if you have chronic ankle instability?
What are the symptoms of chronic ankle instability?
- Pain – usually on the outside of the ankle.
- Stiffness.
- Swelling – can be constant or sometimes come and go.
- Tenderness around the ankle.
- Repeated ankle sprains or sensation of your ankle giving out.
What do stress fractures look like on MRI?

Can you have a stress fracture in your ankle?
Stress fractures are common in foot and ankle bones because we continually place force on them by standing, walking, running and jumping. In a stress fracture, the bone breaks but usually does not shift position (become “displaced”).
What is another name for the ankle mortise?
The tibial plafond, lateral malleolus, and medial malleolus form a mortise, a socket in which the talus sits (Figure 2).
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).
What is ankle AP?

Can ankle instability be cured?
Often, patients with ankle instability can be treated without surgery by strengthening the muscles that control the ankle joint, avoiding high risk activities, and using a supportive brace or shoe to decrease the risk of recurrent sprains.
What does ankle instability feel like?

Over time, an untreated stress fracture can put you at risk of suffering a fracture in the affected bone. Even if the pain appears to go away on its own, without proper treatment, your bones may never have a chance to heal and they may be vulnerable to reinjury.
Is it OK to walk on a stress fracture?
