A patient presents to the Emergency Department with difficulty bearing weight on the right lower extremity after sustaining an inversion injury to the right ankle just prior to presentation. On exam she has moderate right ankle swelling. She is tender over the anterior joint line, particularly laterally. There is no bony tenderness of the malleoli, the calcaneus, the navicular, or the 5th metatarsal. There is no tenderness over the Lisfranc joint. She is tender over the anterior talofibular ligament (ATFL) and the calcaneofibular ligament (CFL). No tenderness with tib-fib compression testing. Right ankle x-rays are obtained (Image 1).
