What does the term circumduction refer to?

Circumduction refers to a specific type of joint movement that involves the circular motion of a limb. When a limb circumducts, it moves in a way that traces out a cone shape, combining flexion, extension, abduction, and adduction in a single smooth motion. This action is typically observed at ball-and-socket joints, such as the shoulder and hip, where the limb can move in a circular pattern while maintaining its connection to the body. The concept of circumduction is important in understanding how different joints work together to produce fluid movement in various activities, highlighting its role in both functional and athletic performance.
