Many thanks to all who chipped in! Everyone agreed that it´s a pathologic fracture at the site of an underlying bone lesion. Concerning this lesion, a sizable majority is in favour of FD. I will try to follow the case and post some f/u. Happy Sunday everyone! Andrei Hi there, is this supposed to be

Mohamed Gaceb shared this with me….I’m guessing it is "PL" which is the Plantaris Longus origin I’ve never seen a femoral avulsion of the Plantaris Longus… maybe I missed it Thanks! There is marrow edema at the cranial margin of the LFC deep to the origin of whatever it is that is torn….it’s next to
