Abstract. The ball-and-socket ankle joint is a malformation of the ankle in which the articular surface of the talus is hemispherical in both the anteroposterior and lateral projections and has a congruent, concave tibial articular surface.
Major gliding joints include the intervertebral joints and the bones of the wrists and ankles. … (3) A pivot joint provides rotation. At the top of the spine, the atlas and axis form a pivot joint that allows for rotation of the head. (4) A condyloid joint allows for circular motion, flexion, and extension.
Beside this, What joint is a pivot joint?
