A fat pad sign at the elbow is indicative of which condition?

• A. Anterior dislocation of the elbow
• B. A radiographic finding indicative of intra-articular fracture
• C. A sign of soft tissue swelling
• D. A confirmation of elbow ligament strain

Answer: (B)

The fat pad sign at the elbow is a crucial radiographic indicator that suggests the presence of an intra-articular fracture. This phenomenon occurs due to the displacement of the fat pads surrounding the elbow joint as a result of bleeding or swelling following a fracture. When there is an intra-articular fracture, such as with a distal humeral fracture, the fat pads typically shift or become more visible on imaging, leading to characteristic 'sail' signs where the anterior and posterior fat pads become elevated. In contrast, although a fat pad sign can relate to other injuries or conditions like soft tissue swelling or ligament strains, it is specifically the association with intra-articular fractures that is most clinically significant. Many soft tissue or ligamentous injuries do not produce the same visual changes in the fat pads observed in imaging. This distinction makes understanding the fat pad sign critical for accurate diagnosis and treatment planning in elbow injuries.
