Which term describes a fracture involving extensive muscle attachment?

An epicondylar fracture is characterized by its association with the bony prominences located at the ends of the long bones, particularly around the elbow and knee regions, where significant muscle attachments exist. These epicondyles serve as the attachment points for various muscles, tendons, and ligaments. When a fracture occurs in these areas, it often involves not just the bone but also the surrounding muscle structures and their functionality.

The presence of extensive muscle attachment around the epicondyles highlights the importance of understanding this type of fracture in clinical settings. Given the potential impact on muscle function and joint stability, special attention must be paid to rehabilitation and recovery following an epicondylar fracture.

In contrast, the other terms describe fractures in different contexts. A supracondylar fracture typically occurs just above the condyles of the humerus and is common in pediatric trauma. A diaphyseal fracture involves the shaft or long part of a bone, while a transcondylar fracture is a less commonly used term that might refer to fractures crossing over the condyles. These terms generally do not encapsulate the significant association with muscle attachment that characterizes an epicondylar fracture.
