The structure known as a bony prominence or projection is termed an epicondyle. An epicondyle is a specific type of bony protrusion located above a condyle, often serving as a site for muscle attachment or ligament attachment. They are typically found on the femur (thigh bone) and humerus (upper arm bone) and play a crucial role in joint stability and movement.

In contrast, other terms like crest, spine, and tubercle describe different types of bony projections. A crest refers to a raised or prominent ridge on a bone, often serving as an attachment point for muscles or tendons. A spine is a sharp or slender projection from a bone, which can serve similar functions. A tubercle, generally, refers to a small rounded projection on a bone that is also an attachment site. Understanding these differences helps clarify why the term epicondyle specifically denotes a bony prominence associated with the points of articulation.
