What is the insertion point of the extensor carpi radialis longus?

The extensor carpi radialis longus is a muscle located in the forearm that plays a crucial role in wrist extension and radial deviation. Its insertion point is specifically at the base of the second metacarpal bone on the dorsal aspect of the hand. This anatomical detail is important for understanding the muscle's function, as its attachment allows for effective movement during activities that involve wrist actions, such as throwing or gripping.

Knowing the correct insertion is vital for sports massage practitioners, as it helps in identifying trigger points or areas of tension in the forearm that can affect wrist functionality. A thorough understanding of muscle insertions also aids in creating more effective treatment plans aimed at enhancing performance or alleviating discomfort in athletes.
