Reading Film
- Anterior humeral line should intersect with middle third of capitellum
- If not, consider supracondylar fracture or lateral condyle fracture
- Line drawn along axis of radial head and neck should pass through middle of capitellum
- If not, consider fracture of lateral condyle, radial neck, Monteggia, or elbow dislocation
- Fat pads
- Anterior may be normal or if large may be abnormal ("sail sign")
- Posterior is always abnormal
