Condyle and Epicondyle

Human anatomy is a fascinating topic, especially when it comes to the names of bones, muscles, and joints. In particular, the topic at hand today is the difference between condyle and epicondyle. Both are bony prominences that are present on the elbow, but their characteristics and functions are different.

Condyle

The condyle is a rounded protuberance at the bottom of the humerus bone that articulates with the ulna and radius at the elbow joint. In essence, the condyle is an articular surface responsible for allowing flexion and extension movements of the forearm.

Epicondyle

On the other hand, the epicondyle is a bony prominence that is located just above the condyle. There are two epicondyles in the humerus: the medial and the lateral. The lateral epicondyle is larger and protrudes more than the medial one.

What is the difference?

The main difference between the condyle and the epicondyle is their function. While the condyle is responsible for allowing flexion and extension movements of the forearm, the epicondyles are anchoring points for the muscles of the forearm. The muscles whose tendon inserts into the lateral epicondyle are important for flexion and extension movements of the wrist. The muscles whose tendon inserts into the medial epicondyle are important for pronation and supination movements of the forearm.

Conclusion

In summary, the difference between the condyle and the epicondyle is that the former is an articular surface that allows flexion and extension movements of the forearm, while the latter are anchoring points for the muscles of the forearm. It is important to understand the anatomy and functioning of each structure in the human body to be able to understand and properly treat the injuries and diseases that may affect them.
