Synovial Joints - Plane Joints

Plane joints allow only gliding or sliding motions. This motion can be in any direction of a single plane. Thus, it is a uniaxial joint. The articular surfaces in plane joints are flat or slightly curved and the movement is restricted by a tight fibrous capsule. Examples of plane joints include the:

1. facet joints (those between articulating surfaces on the vertebrae)
2. intercarpal joints
3. carpometacarpal joints
4. intermetacarpal joints
5. intermetatarsal joints
6. acromioclavicular joints
