A pivot joint (trochoid joint, rotary joint, lateral ginglymus) is a type of synovial joint. In pivot joints, the axis of a convex articular surface is parallel with the longitudinal axis of the bone.
According to one classification system, a pivot joint like the other synovial joint —the hinge joint has one degree of freedom.
