What is the sternoclavicular joint?

The sternoclavicular (SC) joint is one of the four joints that complete the shoulder. The joint is located in the spot where the clavicle (collarbone) meets the sternum (breastbone) at the base of the neck. Although not common, problems with the SC joint can arise from injury and other disorders.

What is the purpose of sternoclavicular joint?

The sternoclavicular joint is a saddle-type joint that allows movement of the clavicle, predominantly in anteroposterior and vertical planes, although some rotation also occurs. The ability to thrust the arm and shoulder forward requires sound function of this joint.

What is the joint classification and type of movement for the sternoclavicular joints?

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 in a fracture of the clavicle before a dislocation of the SC joint.

Is the sternoclavicular joint an intermediate joint?

Although the AC joint is between the shoulder and the clavicle, it is considered an intermediate joint.

Is the sternoclavicular joint a major joint?

The sternoclavicular joint or sternoclavicular articulation is the joint between the manubrium of the sternum and the clavicle bone. It is structurally classed as a synovial saddle joint and functionally classed as a diarthrosis and multiaxial joint….

What is a sternoclavicular injury?

STERNOCLAVICULAR (SC) SPRAINS. [Back] What is it? An SC sprain is an injury to the joint where the clavicle (collarbone) meets the sternum (breastbone). These injuries are rare, requiring an accident with a lot of force, such as a tackle in football or rugby.

What kind of joint is the SC joint?

The sternoclavicular (SC) joint is a saddle-shaped, synovial joint that serves as the primary skeletal connection between the axial skeleton and the upper limb.

What is the joint classification and type of movement for the sternoclavicular joints quizlet?

358: the bony thorax is typically widest at the lateral margins of the eighth or ninth ribs. 358: the sternoclavicular joints are synovial joints, containing articular capsules that permit a plane of motion, or gliding motion, and are therefore termed diarthrodial joints.

What type of joint is the SC joint?

synovial joint
The sternoclavicular (SC) joint is a saddle-shaped, synovial joint that serves as the primary skeletal connection between the axial skeleton and the upper limb.

Which type of joint are SC joints and AC joints?

The sternoclavicular (SC) joint connects the collarbone (clavicle) to the breastbone (sternum). At the other end of the collarbone, the acromioclavicular (AC) joint connects the clavicle to the acromion, the highest point of the shoulder blade.

What causes sternoclavicular joint pain?

Injuries to the SC joint are called sternoclavicular joint injuries and can include stretching or tearing of the ligaments. It is usually caused due to severe trauma or a direct blow to the side of your body such as in motor vehicle accidents or contact sports like football or rugby.

Why is my SC joint swollen?

Swelling of the SCJ is commonly due to trauma, degeneration, infections and other disease processes that affect synovial joints.

What is a sternoclavicular joint also known as?

The sternoclavicular joint, also known as the SC joint, is the bony joint that links the arm to the torso and creates the movement of the collarbone. Joint dislocations are the most common injuries to the SC joint. Displacements to the SC joint are classified as either an anterior (frontwards) sternoclavicular joint dislocation or a posterior

What type of joint that connects shoulder and clavicle?

The acromioclavicular joint, or AC joint, is a joint at the top of the shoulder. It is the junction between the acromion (part of the scapula that forms the highest point of the shoulder) and the clavicle. It is a plane synovial joint. The joint is stabilized by three ligaments :

Where does the clavicle meet the sternum?

The sternoclavicular joint is where the clavicle, or collarbone, meets the sternum, or breastbone. As the skeleton tends to be symmetrical, there are two sternoclavicular joints which mirror each other, one on the left and one on the right.

Is the acromioclavicular joint a synovial joint?

The Acromioclavicular Joint. The acromioclavicular joint is a plane type synovial joint. It is located where the lateral end of the clavicle articulates with the acromion of the scapula . The joint can be palpated during a shoulder examination; 2-3cm medially from the ‘tip’ of the shoulder (formed by the end of the acromion).
