Dislocation.
If you mean as in bones, two or more bones form the joint. There are also stabilizing ligaments that help form the joint. If you mean a joint between two or more wood pieces, those are held together with fasteners or glue.
Three bones meet at the elbow joint: the humerus (upper arm bone), the radius, and the ulna (forearm bones). These bones come together to form a hinge joint that allows for flexion and extension of the arm.
The four bones that form the ankle joint are the tibia, fibula, talus, and calcaneus. The tibia and fibula are the bones of the lower leg that articulate with the talus, which sits on top of the calcaneus, or heel bone.
A joint that does not allow any movement is called a synarthrosis joint. This type of joint can be found in the skull, where two bones have a suture line that is immovable. An example is the joint between the two parietal bones of the skull.
The bones next to the carp joint are the radius and ulna in the forearm, and the metacarpal bones in the hand. These bones form the structure that supports and allows movement at the carpometacarpal joint.
I think it might be a ball and socket joint of a universal joint.

The bones that form the hinge joint at your elbow are the humerus, ulna, and radius. The humerus is the upper arm bone, while the ulna and radius are the two forearm bones. These bones come together to allow the elbow to bend and straighten.
Dislocation
Where two bones come together or "join" is called a "joint".
Cartilage covers the ends of bones at joints, while a ligament is the tissue that connects two bones to form a joint.
