What is sternoclavicular joint?
Sternoclavicular joint is a place where the collarbone or collarbone encounters bone or breast. Since the skeleton is symmetrical, there are two sternoclavicular joints that mirror each other, one left and one right. The joint is surrounded by capsules and fibrous belts known as ligaments, helping to strengthen. The dislocation of the sternoclastic joint is rare due to the stability provided by these hard ties, and the fracture of the collarbone is more likely to be more likely. Together with other synovial joints, the sternoclavicular joint is closed by a capsule, lined with a thin layer of tissue known as the synovial membrane. This membrane produces liquid that lubricates the joint. The articulation surfaces of the collarbone and thoracic bones are covered with fibrous cartilage, which helps to be smoother and more resistant during joints. The disk acts as a shock shock for forces passengers along the collarbone. It lies between articulating bone surfaces and connects to the capsule on the sides.
Sternoclavicular joint is known as a saddle joint that allows movement in two different directions. This allows collarbones to move back and forward and lift up and down. The joint is well supported by its ligaments and the overall range of movement is relatively limited.
A particularly strong ligament called Costoclavice Ligament connects to the collarbone to the cartilage of the first rib, which makes the joint quite stable. Occasionally, perhaps in sports, dislocation occurs when the person lands with one arm on the ground and the other shoulder is hit from above. The end of the collarbone is separated from the joint, pushing down and forward. Symptoms include pain and swelling of the joint and treatment usually involves a combination of pain relief and relaxing joint in the strap. In more complex cases, the joint repair operation may be required.
Sometimes there is a condition in young people that mimics the dislocation of sternoclavicular joint. At the end of the collar toThe area is an area of cartilage called growth plate. The growth plate does not develop into the bone until the adolescent years end and if it breaks, sternoclavicular dislocation may resemble. The doctor will be able to distinguish the difference and most cases of growth plate fractures without any special treatment.
