Sternoclavicular joint: Bones, ligaments, movements | Kenhub
Oct 30, 2023 · The clavicular and sternal joint surfaces are convex and concave, respectively. These curvatures are found in the vertical plane. In the horizontal plane the articular surface of the clavicle is slightly concave while that of the sternum is …
Arthrokinematics of the Sternoclavicular Joint
It is important to understand that the sternoclavicular joint is a saddle joint. It gets its name from the shape as it has a concave surface in one direction and convex in another, like a saddle. The medial aspect of the clavicle is concave anterior-to-posterior and convex superior-to-inferior.
Sternoclavicular Joint - Physiopedia
During protraction, the concave surface of the medial clavicle moves on the convex sternum, producing an anterior glide of the clavicle, and anterior rotation of the lateral clavicle.

Sternoclavicular joint - PMC
The sternoclavicular joint (SCJ) is a saddle shaped, synovial joint and is the only skeletal articulation between the axial skeleton and the upper limb. The medial end of the clavicle has a larger surface area and thicker hyaline cartilage than the adjacent sternum.
The Sternoclavicular Joint - Musculoskeletal Key
Oct 22, 2016 · The articular surfaces of the sternum and medial clavicle are incongruent, although the medial clavicle typically exists in a “saddle” configuration (i.e., concave in the axial plane and convex in the coronal plane).
Clavicle - Structures, Muscle Attachments, 3D Model
Mar 1, 2022 · The clavicle is a double curved long bone which connects the arm to the trunk. It articulates medially with the sternum at the sternoclavicular joint, and laterally with the acromion process of the scapula.
The Clavicle is curved convex forwards at its medial end Anterior Lateral Medial Posterior
Sternoclavicular Joint - an overview | ScienceDirect Topics
The ligamentous structures provide the stability of the joint. The proximal surface of the clavicle is convex in the coronal plane but somewhat concave in the transverse plane. The joint angles from the anteromedial to the posterolateral in the axial plane.
