Saddle joints are said to be biaxial, [5] allowing movement in the sagittal and frontal planes. [2] Examples of saddle joints in the human body include the carpometacarpal joint of the thumb, [6] [7] the sternoclavicular joint of the thorax, [8] the incudomalleolar joint of the middle ear, [9] and the calcaneocuboid joint of the heel. [2]
The movements of the first CMC are limited by the shape of the joint, by the capsulo-ligamentous complex surrounding the joint, and by the balance among involved muscles. If the first metacarpal fails to sit well 'on the saddle', for example because of hypoplasia , the first CMC joint tends to be subluxated (i.e. slightly displaced) towards the ...
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.

The sternoclavicular joint or sternoclavicular articulation is a synovial saddle joint between the manubrium of the sternum, and the clavicle, and the first costal cartilage. The joint possesses a joint capsule , and an articular disc , and is reinforced by multiple ligaments.
“A saddle that is too low will keep your knee angle too tight at the top of the stroke, which increases the shear forces pulling the patella against the femur, which in turn increases the ...
Joints can also be classified functionally according to the type and degree of movement they allow: [1] [12] Joint movements are described with reference to the basic anatomical planes. [3] synarthrosis – permits little or no mobility. Most synarthrosis joints are fibrous joints, such as skull sutures. This lack of mobility is important ...
It is a saddle type of synovial joint but functions as a plane joint. The sternoclavicular joint accommodates a wide range of scapula movements and can be raised to a ...
