Sternoclavicular dislocation is rare, [2] but may result from direct trauma to the clavicle or indirect forces applied to the shoulder. [4] Posterior dislocations deserve special attention, as they have the potential to be life-threatening because of the risk of damage to vital structures in the mediastinum ; [ 5 ] surgery can be used to fix ...
The anterior sternoclavicular ligament is a broad band of fibers attached to the clavicle above, and to the manubrium below. The ligament overlies the anterior (front) surface of sternoclavicular joint .
The articular disc of the sternoclavicular joint is flat and nearly circular, interposed between the articulating surfaces of the sternum and clavicle.. It is attached, above, to the upper and posterior border of the articular surface of the clavicle; below, to the cartilage of the first rib, near its junction with the sternum; and by its circumference to the interclavicular and anterior and ...
The sternoclavicular joint is the articulation of the manubrium of the sternum and the first costal cartilage with the medial end of the clavicle. 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 60° angle
A separated shoulder, also known as acromioclavicular joint injury, is a common injury to the acromioclavicular joint. [2] The AC joint is located at the outer end of the clavicle where it attaches to the acromion of the scapula. [2] Symptoms include non-radiating pain which may make it difficult to move the shoulder.
Brown sustained a sternoclavicular joint sprain in the Chiefs’ 26-13 loss at EverBank Stadium, coach Andy Reid confirmed after the game. ... Hill went down with a sternoclavicular joint ...
The acromioclavicular joint and sternoclavicular joint also play a role in shoulder movements. [3] White hyaline cartilage on the ends of the bones (called articular cartilage) allows the bones to glide and move on each other, and the joint space is surrounded by a synovial membrane. Around the joint space are muscles - the rotator cuff, which ...
The posterior sternoclavicular ligament is a band of fibers, covering the posterior surface of the sternoclavicular joint. It is attached above to the upper and back part of the sternal end of the clavicle, and, passing obliquely downward and medialward, is fixed below to the back of the upper part of the manubrium sterni.
