In
anatomy, a biaxial joint is a freely mobile
joint that allows movement in two
anatomical planes.[1] An example of a biaxial joint is a
metacarpophalangeal joint of the hand.[2] The joint allows for movement along one axis to produce bending or straightening of the finger, and movement along a second axis, which allows for spreading of the fingers away from each other and bringing them together.[3]
