May be used to reveal associated ligamentous injuries, osteochondral fractures and chondral fractures 7. fragment number and orientation/relationshipįor the same reasons, CT aids in treatment planning as well 6.
#Trimalleolar fx series
Standard ankle series suggested AP, lateral and mortise (best view to define displacement). The uncommon medial variation usually occurs with an adduction force 9. Pathology MechanismĮxternal rotation and supination is the main mechanism of injury in lateral triplane fractures. Possible signs include swelling, localized/referred pain, and/or deformity of the ankle. Symptoms comprise of pain and inability to weight bear. If intra-articular, called reverse Barton fracture BACK to TOPįracture dislocation involving the midtarsal joints in which there is superior dislocation of the navicular and cuboid bones on the talus and calcaneus BACK to TOPįracture of shaft of radius associated with dislocation of distal radioulnar joint-īaseball finger (a.k.a.In adolescents with closing epiphyseal plate(s) they are the most common ankle joint fractures - along with Tillaux fractures.
