- Synovial joints allow for various types of movement and are classified based on their axes of motion
Nonaxial Joints
- Nonaxial joints, also known as gliding joints, allow for movement in a single plane.
- They have a flat articular surface.
- Examples include intercarpal, intertarsal, sacroiliac, vertebrocostal, acromioclavicular, and calviculosternal joints.
Monoaxial Joints
- Monoaxial joints allow for angular movement in one axis.
- Hinge joints are a type of monoaxial joint made of cylindrical projections fitting into a trough-shaped structure.
- Examples of hinge joints include the elbow, knee, ankle, and interphalangeal joints.
- Another type of monoaxial joint is the rotational or pivot joint which allows for uniaxial rotation around a long axis.
- Examples of pivot joints include the atlas/axis joint and the proximal radioulnar joint.
Biaxial Joints
- Biaxial joints permit angular movement in two axes.
- Condyloid (ellipsoid) joints are a type of biaxial joint.
- Examples include the radiocarpal joint, metacarpophalangeal joints (2-5), and metatarsophalangeal joints.
- Saddle joints are another type of biaxial joint that are concave-convex.
- Saddle joints allow for more movement than condyloid joints.
- An example is the 1st carpometacarpal joint.
Multiaxial Joints
- Multiaxial joints, also known as ball-and-socket joints, allow for movement in multiple axes.
- The rounded head fits into a cup-shaped cavity.
- Ball-and-socket joints are the most freely moving type of joint.
- Examples include the shoulder and hip joints.
