Lucency projected across the radial neck. Possible fracture.
Case Discussion
Large joint effusion following trauma in children in their mid-teens are likely to be the result of proximal radial fractures rather than supracondylar fracture. Supracondylar fractures are much more common in younger pre-teenage children.
