Pivot Synovial Joint

BY: Marle Knowles, Anna Crowley, Alexi Lund

An example of a pivot synovial joint is in the neck vertebrae. The Atlas (C1) rotates around the Axis (C2) to enable lateral neck movement. Another example is the rotation of the ulna on the radius.


The movement performed by the pivot synovial joint is rotation. For example the neck will rotate to the left and right. Another movement is in the arm with the rotation of the ulna on the radius.


For the neck, the Sternocleidomastoid (SCM) are involved with the movement of the pivot synovial joint. There is a left and right SCM that work together to move the head around to the left and right. The splenius

The Transverse Ligament is what places and guides the rotation of the pivot synovial joint in the cervical joint ( First picture below). In the radioulna joint the Annular ligament is what holds the bone in place while is rotates (second picture below).


The cervical joint allows for the neck to move the head back and forth, like to say no. An example of that motion in the radioulnar joints would be swinging a racket around in tennis to hit a tennis ball. The last movement of the stroke makes the racket face downward. That is the ulna rotating the radius.


Diseases and injuries of the pivot synovial joint:

- Cervical Degenerative disc disease causes the neck to stiffen.

- Osteoarthritis is the most common form of arthritis where the cartilage breaks down.

-Septic arthritis is an infection in the joint.

5 Facts

-  It works in conjunctions with other joints so the neck can go all different directions.

- There are two radioulnar joints, one proximal and one distal.

-  There are on two true pivot synovial joints in your body, the cervical and the radioulnar.

- Its also called the trochoid joint.

- There are many joints that allow for pivoting movements like the hips and spin but are not real pivot synovial joints.
