How do you stabilize the sternoclavicular joint?
Shoulder flexion (lying down)
- Lie on your back, holding a wand with your hands. Your palms should face down as you hold the wand.
- Keeping your elbows straight, slowly raise your arms over your head until you feel a stretch in your shoulders, upper back, and chest.
- Hold 15 to 30 seconds.
- Repeat 2 to 4 times.
How is sternoclavicular joint divided?
The articular surfaces are covered with fibrocartilage (as opposed to hyaline cartilage, present in the majority of synovial joints). The joint is separated into two compartments by a fibrocartilaginous articular disc. Fig 1 – The articulating surfaces of the sternoclavicular joint.
What Innervates the sternoclavicular joint?
Innervation. The sternoclavicular joint is innervated from two sources; superficially by the medial supraclavicular nerve (C3-C4; cervical plexus) and deeply by the nerve to subclavius (C5-C6; brachial plexus).
Why is my sternoclavicular joint swollen?
The sternoclavicular joint (SCJ) is an integral part of the shoulder girdle that connects the upper limb to the axial skeleton. Swelling of the SCJ is commonly due to trauma, degeneration, infections and other disease processes that affect synovial joints.
What level is 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.
How is sternoclavicular arthritis treated?
Nonsurgical treatment can include a trial of activity modification, anti-inflammatory medications, physical therapy, and possible corticosteroid injections. Patients with persistent pain despite appropriate nonsurgical management may benefit from surgical treatment with resection arthroplasty.
Where is the articulation of the sternoclavicular joint?
The Sternoclavicular Joint (SC joint) is formed from the articulation of the medial aspect of the clavicle and the manubrium of the sternum.
What are the four major ligaments of the sternoclavicular system?
There are four major ligaments: Sternoclavicular ligaments (anterior and posterior) – these strengthen the joint capsule anteriorly and posteriorly. Interclavicular ligament – this spans the gap between the sternal ends of each clavicle and reinforces the joint capsule superiorly.
How is the depression of the sternoclavicular joint limited?
Which is weaker the sternoclavicular ligament or the scapula?
Weaker than the Anterior Sternoclavicular Ligament. Sternal end of one clavicle to sternal end of the other clavicle. There are no muscles that act directly on the SC Joint. However, the SC Joint motions closely mimic the reciprocal motions of the scapula.
