Multiaxial joint

A multiaxial joint (polyaxial joint or triaxial joint) is a diarthrosis that allows for several directions of movement.

Details
In the human body, the shoulder and hip joints are multiaxial joints. They allow the upper or lower limb to move in an anterior-posterior direction and a medial-lateral direction. In addition, the limb can also be rotated around its long axis. This third movement results in rotation of the limb so that its anterior surface is moved either toward or away from the midline of the body.
