A hinge joint ( ginglymus or ginglymoid ) is a bone joint in which the articular surfaces are molded to each other in such a manner as to permit motion only in one plane. [1] According to one classification system they are said to be uniaxial (having one degree of freedom ). [2] The direction which the distal bone takes in this motion is seldom in the same plane as that of the axis of the proximal bone; there is usually a certain amount of deviation from the straight line during flexion .
The articular surfaces of the bones are connected by strong collateral ligaments .
The best examples of ginglymoid joints are the Interphalangeal joints of the hand and those of the foot and the joint between the humerus and ulna . The knee joints and ankle joints are less typical, as they allow a slight degree of rotation or of side-to-side movement in certain positions of the limb . The knee is the largest hinge joint in the human body.
Hinge and pivot joints are both types of synovial joint . A hinge joint can be considered a modified sellar/saddle joint , with reduced movement. [3]
