Features of Saddle Joints
Saddle joint has the following features:
- Saddle joints allow for angular movements similar to condyloid joints, but with a greater range of motion.
- A saddle joint includes one concave bone and another convex bone.
- Saddle joints are highly flexible.
- Saddle joints allow for flexion, extension, adduction, abduction, and circumduction. However, axial rotation is not allowed.
- Saddle joints provide a balance of stability and mobility. It contribute to the precise and versatile movements.
- The joint surfaces are covered with articular cartilage which reduces friction. The joint cavity contains synovial fluid for lubrication.
- Saddle joints are similar to condyloid joints in functional appearance.
- The closely placed articulating surfaces reduce the risk of dislocation.
- An example of a saddle joint is the thumb joint.
Saddle Joints
The saddle joint is a type of synovial joint that allows a wide range of movements. movement in two planes. Joints are characterized by the presence of two reciprocal concave and convex surfaces, that allow movement in two planes. These planes are flexion/extension and abduction/adduction. In the human body, the saddle joint can be found in the carpometacarpal joint of the thumb, the incudomalleolar joint of the middle ear, the sternoclavicular joint of the thorax, and the calcaneocuboid joint of the heel.
