Jason SR Print(0) ID 1181041869 T1 Elbow Fractures T2 The Atlas of Emergency Medicine, 5e YR 2021 FD 2021 PB McGraw-Hill PP New York, NY SN 9781260134940 LK accessemergencymedicine.mhmedical.com/content.aspx?aid=1181041869 RD 2024/03/28 AB Direct trauma or fall on an outstretched hand may result in elbow fractures. The patient may be unable to extend the elbow and have pain on supination/pronation. AP, lateral, and oblique radiographic views can visualize most fractures. The radial head should be aligned with the capitellum on all views. The anterior fat pad may be seen on normal radiographs, but displacement anteriorly and superiorly (sail sign) suggests effusion or hemarthrosis. The posterior fat pad is not normally visualized, but if seen is indicative of effusion or hemarthrosis.
