It lies between the articulating bony surfaces and joins to the capsule at the sides.The sternoclavicular joint is what is known as a,Sometimes a condition occurs in young people which mimics dislocation of the sternoclavicular joint. The sternoclavicular joint is a synovial saddle joint that connects the sternum with the clavicles.

This enables the clavicle to move backward and forward and to lift up and down. Function of the Sternoclavicular Joint The sternoclavicular joint is the most frequently moved, nonaxial joint in the body.40 It acts similar to a ball and socket joint, allowing for motion in almost all planes, including rotation. Specifically, the movements … Posterior dislocations are treated with closed reduction, which is successful in most cases. Careful evaluation is required to rule out life-threatening injuries to the respiratory, vascular, or neurologic structures that are adjacent to the SCJ. The growth plate does not develop into bone until one's teenage years are over and, if broken, it can resemble a,Wikibuy Review: A Free Tool That Saves You Time and Money,15 Creative Ways to Save Money That Actually Work.What Are the Different Treatments for Clavicle Swelling. Surgery can be entertained in those few patients in whom anterior instability remains symptomatic.SC instability can be classified according to degree (subluxation or dislocation), direction (anterior or posterior), etiology (traumatic or atraumatic), and chronicity (acute, chronic, recurrent, congenital, or developmental).The S-C joint is difficult to visualize on plain chest or shoulder radiographs. It contains an intra-articular disk or meniscus that helps provide congruity and stability. It is one of four joints that compose the Shoulder Complex. The surgeon should be familiar with the anatomy and proximity of vital structures prior to treating these injuries as catastrophic complications can occur. The function of the sternoclavicular joint is to coordinate the movements of the upper limb with the core of the body.

While not as well accepted as computed tomography for trauma, magnetic resonance imaging has been found to reliably identify damage to the intra-articular disk and supporting ligamentous structures.The sterno-clavicular joint seems poorly understood and more poorly researched, but it is accepted that this is, in part, due to the rarity of significant injury to the joint. The anterior capsule is supported by anterior sternoclavicular ligaments, which provide support against anterior translation of the joint. This membrane produces fluid which lubricates the joint. The disc acts as a shock absorber for forces traveling along the clavicle.

In common with other synovial joints, the sternoclavicular joint is enclosed by a capsule, lined with a thin layer of tissue known as a synovial membrane. The sterno-clavicular joint is oriented somewhat posterior, lateral, and upward. Computed tomography should be performed to visualize any acute injury to the S-C joint. The most familiar is the serendipity view, initially described by Rockwood and Wirth.Computed tomography is now recognized as the most reliable way to identify abnormalities of the S-C joint. Several radiographic views have been described in a specific attempt to better visualize the S-C joint.

Open reduction may be required when closed reduction is unsuccessful.

The Sternoclavicular Joint (SC joint) is formed from the articulation of the medial aspect of the clavicle and the manubrium of the sternum. The sterno-clavicular joint is a shallow, relatively incongruous joint supported by a strong ligamentous complex. Additional research is needed to determine the best practices for the treatment of SCJ trauma.An acute traumatic anterior or posterior dislocation of the sternoclavicular joint should undergo an attempt at closed reduction in the operating room. It is the only true joint which connects the appendicular skeleton of the upper limb with the axial skeleton of the trunk. Treatment of most anterior dislocations is nonoperative with good outcomes.

Open reduction with repair or reconstruction of the sternoclavicular joint capsule is indicated for irreducible posterior dislocations because a chronically dislocated clavicular head can erode into the mediastinal contents, causing late complications (.For these reasons, a chronic posterior dislocation of the sternoclavicular joint is an indication for open reduction and reconstruction of the stabilizing ligaments. SC injury is usually the result of high-energy force sustained during a motor vehicle accident (50%) or during contact sports activity (20%).SCJ injuries are uncommon but can include dislocations and medial clavicle fractures. Thus allowing the upper limb to perform its full range of motion. For posterior dislocations, compression of structures behind the medial end of the clavicle can be well seen on computed tomography. However, as physical therapists continue to gain the privilege of direct access to patients it is essential they become aware of how to differentiate between pathological conditions of this joint that may be either health or life threatening demanding a medical consult or that require a physical therapy intervention. Unrecognized mediastinal vascular injury could be life-threatening in acute posterior sternoclavicular joint dislocations.We use cookies to help provide and enhance our service and tailor content and ads. Posteriorly, th… The SC joint is generally classified as a plane style synovial joint and has a fibrocartilage joint disk.The ligamentous reinforcements of this joint are very strong, often resulting a fracture of the clavicle before a dislocation of the SC Joint. The joint is well supported by its ligaments and the overall range of motion is fairly limited.

The shadows from surrounding structures overlap the outlines of the joint. The sternoclavicular joint allows movement of the clavicle in three planes, predominantly in the anteroposterior and vertical planes, although some rotation also occurs.
