Pivot joint. In animal anatomy, a pivot joint (trochoid joint, rotary joint or lateral ginglymus) is a type of synovial joint whose movement axis is parallel to the long axis of the proximal bone, which typically has a convex articular surface. According to one classification system, a pivot joint like the other synovial joint —the hinge ...
A multiaxial joint, such as the hip joint, allows for three types of movement: anterior-posterior, medial-lateral, and rotational. A multiaxial joint (polyaxial joint or triaxial joint) is a synovial joint that allows for several directions of movement. [9] In the human body, the shoulder and hip joints are multiaxial joints.

articulatio atlantoaxialis mediana, articulatio atlantoaxialis lateralis. MeSH. D001268. FMA. 25524. Anatomical terminology. [edit on Wikidata] The atlanto-axial joint is a joint in the upper part of the neck between the atlas bone and the axis bone, which are the first and second cervical vertebrae. It is a pivot joint.
Anterior aspect. The ball-and-socket joint (or spheroid joint) is a type of synovial joint in which the ball-shaped surface of one rounded bone fits into the cup-like depression of another bone. The distal bone is capable of motion around an indefinite number of axes, which have one common center. This enables the joint to move in many ...
35290. Anatomical terminology. [edit on Wikidata] The distal radioulnar articulation[1] (also known as the distal radioulnar joint, [2] or inferior radioulnar joint [1][3]) is a synovial pivot joint between the two bones in the forearm; the radius and ulna. It is one of two joints between the radius and ulna, the other being the proximal ...
The knee joints and ankle joints are less typical, as they allow a slight degree of rotation or of side-to-side movement in certain positions of the limb. The knee is the largest hinge joint in the human body. Hinge and pivot joints are both types of synovial joint. A hinge joint can be considered a modified sellar/saddle joint, with reduced ...
The movements of saddle joints are similar to those of the condyloid joint and include flexion, extension, adduction, abduction, and circumduction. [1] However, axial rotation is not allowed. Saddle joints are said to be biaxial, [5] allowing movement in the sagittal and frontal planes. [2]
A subluxation of the humeroradial joint is called a "nursemaid's elbow", also known as radial head subluxation. [1] It is generally caused by a sudden pull on the extended pronated forearm, such as by an adult tugging on an uncooperative child or by swinging the child by the arms during play. In radial head subluxation, there is little ...
