Answer:
The saddle joint that can be found in the thumbs ensures that it moves from side to side and rotate on its own axis alone.
The saddle joint allows movement in different directions but only a small amount of rotation. The thumb is the only organ that has a saddle joint.
It should be noted that the bones that are in the saddle joint ensure the back and forth movement of the thumbs.
The pivot joint is the joint that's responsible for ensuring that one bone rotates around another bone. Ball and socket joint can be found in the shoulder and the hip and it allows for greater freedom of movement.
When compared to other movable joints, the saddle joint is prone to dislocation because it's free-moving and rotates on its own axis alone.
In conclusion, if the thumb contained a pivot joint or a ball and socket joint, it'll be able to move more freely.
I hope this helps! :)
