A Hinged Expansion joint is an assembly designed to absorb angular rotation in the plane perpendicular to the hinge pins. The hardware consists of two hinged plates 180 Â° apart and joined to the end connection.
Ball-and-socket joints are classified functionally as multiaxial joints because they can move bones along several axes. The muscles that surround the joints permit the humerus and femur to move away from the bodyâs midline (abduction), toward the bodyâs midline (adduction), forward (flexion), and backwards (extension).
