Where is the SC joint located?
Where is the SC joint located?
shoulder
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.
What is the best imaging technique to evaluate for a SC joint dislocation?
The computed tomography (CT) scan was found to be the best diagnostic procedure to assess the integrity of the sternoclavicular joint. The cause of the dislocation was most commonly lateral compression of the shoulders sustained during contact sports, particularly football and hockey.
How many degrees of elevation should be present at the sternoclavicular joint?
The elevation is assumed to be 45 degrees and the depression to be 10 degrees. The elevation is limited by the tension of the costoclavicular ligament and the subscapularis muscle. Depression is limited by the superior sternoclavicular ligament, the interclavicular ligament, and by the bony contact with the first rib.
What axis does the SC joint move around?
Mobility and Stability Type of joint – being a saddle joint it can move in two axes. Articular disc – this allows the clavicle and the manubrium to slide over each other more freely, allowing for the rotation and movement in a third axis.
What is the close packed position of the sternoclavicular joint?
The sternoclavicular joint takes a closed packed position when the clavicle is maximally (posteriorly) rotated, as occurs during maximum arm elevation and full scapular rotation. While the open (resting) position occurs when the arm is resting by the side.
What is the imaging modality of choice for evaluation of joint suspected sternoclavicular joint injury?
Radiographs are the initial imaging modality of choice in suspected sternoclavicular separations or dislocations. Anterior-posterior views may be helpful; lateral views are unlikely to be of significant utility to assess the joint due to superimposed structures.
What is serendipity view?
The serendipity view is a specialized radiographic projection utilized in the setting of suspect dislocations of the sternoclavicular joint. The projection is seldom used in departments with functioning computed tomography, but still utilized in postoperative imaging.
How many degrees of freedom does the sternoclavicular joint have?
The sternoclavicular joint is a diarthrodial joint with three degrees of freedom that is relatively immobile and incongruent. It is the only articulation between the upper limb and trunk.
What position is the close packed position for the Radiohumeral joint?
What is the close packed position of the radiocarpal joint? The close packed position of the radiocarpal joint is wrist extension with radial deviation. The radiocarpal joint has two degrees of freedom. It is encased in a strong capsule reinforced by numerous ligaments shared with the midcarpal joint.
Is inferior angle of scapula palpable?
FIGURE 5-9 Inferior angle of the scapula: Palpate along the medial border of the scapula from the superior angle down to the inferior angle of the scapula. FIGURE 5-10 Lateral border of the scapula: Once you are at the inferior angle of the scapula, continue palpating superiorly along the lateral border of the scapula.
How do you stabilize the sternoclavicular joint?
Sit in a firm chair, or stand up straight. Keeping your chin level, turn your head to the right, and hold for 15 to 30 seconds. Turn your head to the left, and hold for 15 to 30 seconds. Repeat 2 to 4 times to each side.
