Các khớp sternoclavicular diarthrodial chung là Các trục và appendicular Giữa các bộ xương. Nó là tùy thuộc vào các quá trình đó xảy ra dịch bệnh tương tự trong khớp, thoái hóa khớp bao gồm, viêm khớp dạng thấp, nhiễm trùng, và subluxation. Hầu hết những hoàn cảnh hiện tại với sưng khớp, | Atraumatic Disorders of the Sternoclavicular Joint Thomas O. Higginbotham MD and John E. Kuhn MD Abstract The sternoclavicular joint is the diarthrodial articulation between the axial and appendicular skeletons. It is subject to the same disease processes that occur in joints including degenerative arthritis rheumatoid arthritis infection and subluxation. Most of these conditions present with swelling of the joint which may be associated with pain and or tenderness. Plain radiographs can demonstrate changes on both sides of the joint. Because of variations in anatomy computed tomography scans and magnetic resonance images are often necessary to clarify the pathology. With the exception of acute infection most conditions can be managed nonsurgically with joint resection reserved for patients with persistent symptoms. J Am Acad Orthop Surg 2005 13 138-145 The sternoclavicular joint a saddleshaped synovial joint is the only bony articulation between the axial and appendicular skeletons Fig. 1 A . The large medial clavicle articulates somewhat incongruently with a shallow socket formed by the superomedial manubrium and the first costal cartilage creating a joint with little inherent bony stability. Between the two articular surfaces is a dense fibrocartilaginous articular disk separating the joint into two distinct synovial cavities. An intra-articular disk ligament originates from the junction of the first rib and sternum passes through the sternoclavicular joint and attaches on the posterior and superior medial clavicle. That ligament contributes to joint stability and prevents medial displacement of the clavicle. It is contiguous with the anterior and posterior sternoclavicular ligaments which are thickenings of the fibrous joint capsule that function as the primary restraints to anterior and posterior translation of the medial The joint capsule extends laterally to include the epiphysis of the clavicle. The sternoclavicular joint also is reinforced .
