WebAug 22, 2016 · Uniaxial Joints There are two types of synovial uniaxial joints: (1) hinge and (2) pivot. Hinge joints act similar to the hinge of a door. One surface is concave and the other is shaped similar to a spool. Flexion and extension are allowed in the sagittal plane around a mediolateral axis. 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. According to one classification system they are said to be uniaxial (having one degree of freedom). 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; the…
