What is a key characteristic of an epicondylar fracture?

An epicondylar fracture is characterized by its involvement with the distal humerus, specifically around the bony prominences known as the epicondyles. These are located at the lower end of the humerus near the elbow and play a crucial role in the attachment of muscles and ligaments that facilitate elbow movement. The fracture usually occurs as a result of a fall or direct trauma and can significantly affect joint function due to the proximity to the elbow joint itself and the surrounding musculature.

In contrast, a fracture located in the shaft of a bone would not be classified as epicondylar since it is not near the joint or epicondyles. Similarly, a fracture impacting the cartilaginous growth plate pertains more to pediatric fractures related to growth, which does not describe the adult epicondylar fracture pattern. Lastly, the mention of muscle attachments without cellular extensions is not a relevant characteristic of epicondylar fractures, as these fractures are inherently associated with the bony structures that support muscle connection.
