Ankle Fractures & X Rays - Everything You Need To Know - Dr. Nabil Ebraheim

Dr. Ebraheim’s educational animated video describes about fractures of the ankle X - rays, ankle fracture classification,ankle fracture dislocation, it also describes ankle fracture treatment and ankle fracture surgery and ankle fracture recovery. The Mortise view is about 15° of internal rotation. The medial clear space should be 4-5 mm or less, and it should be equal to the superior clear space which is between the talus and the distal tibia on the mortise view. If the medial clear space appears widened before surgery, then there is a deltoid injury. If the medial clear space does not appear widened, then make sure that you do not have a supination- external rotation type 4 injury. You may need to do stress view x-rays before surgery in order to prove that the deltoid ligament is or is not injured. The tiblofibular clear space should be less than 6 mm on the mortise view and it is the distance between the medial border of the fibula and the tibial Incisura notch. If the tiblofibular clear space is widened and the ankle mortise is unstable, this allows the talus to shift because the syndesmosis is unstable. 1 mm of talar shift will give a 42% decrease in tibiotalar contact area. This will cause future, accelerated arthritis. The tiblofibular overlap is about 10 mm in the AP view and you measure that from the medial border of the fibula. In the mortise view, the tibiofibular overlap should be more than 1 mm. Talo-Crural Angle I don’t use this and find not much value in this measurement except on exam questions! The lateral malleolus is longer than the medial malleolus, if the fibula is short, I can rely on two other x-ray measures that can help me: 1- Shenton’s Line: The subcondylar bone of the tibia and fibula should form a continuous line around the talus, so if the fibula is short then the spike of the fibula will too proximal. If the fibula is long then the spike of the fibula will too distal. Always look for the broken line from the lateral part of the articular surface of the talus to the distal fibula. 2- Dime Test Look for the sprung mortise. Look for the spike of the fibula to proximal. Look for the broken Shenton’s Line. Look for the Dime Test. Look for medial clear space widening. Get a lateral x-ray to see if there is a posterior malleolus fracture. See if there is any talar subluxation. See if there is any other associated Injuries from the talus and the calcaneous. The most important thing you will see on the lateral view x-ray of the ankle is the type of fracture: is it a Pronation - External rotation or Supination - External rotation Injury. you will see that from the direction of the fracture. or Is the fracture comminuted? So you can say this is Pronation - Abduction Injury.
