Hinge joints are a type of synovial joint that permit movement in one direction like the hinge on a door. Usually this is achieved by a concave surface articulating with a corresponding convex surface.
Hinge joints allow for movement in a single translational plane only. This one degree of freedom is typically in the flexion / extension direction in the human body.
- flexion / extension
These joints primarily allow for hinge type movement but are modified to allow for some limited motion in other directions.
