articulatio trochoidea

Meaning

A synovial joint where a bony process rotates within a ring formed by another bone and a ligament, allowing only rotational movement around a single axis.

Examples

• The atlantoaxial joint is a prime example of an articulatio trochoidea in the human cervical spine.
• An articulatio trochoidea restricts movement to rotation, unlike the more flexible ball-and-socket joints.
