Shoulder care treatment in las vegas USA America
All the body’s joints, those in the shoulder are the most mobile and have incredible range of motion. They rotates the arm in a full circle as well as elevate it upward, downward, forward, backward, and more.
At the shoulder, three major bones meet and create a 90-degree angle:
- Clavicle: Also known as the collarbone, the clavicle extends across the front of the shoulder from the sternum to the scapula. It helps stabilize the shoulder’s movements.
- Scapula: More commonly known as the shoulder blade, the scapula is a flat triangular bone located in the upper back. It connects with the collarbone at the front of the body.
- Humerus: The largest bone of the arm, the humerus connects to the scapula and clavicle in the shoulder. The head of the bone has a ball-like knob to create a ball-and-socket joint with the scapula.
The junctions of these three bones and the sternum (chest bone) form three joints:
- Glenohumeral joint: This shallow ball-and-socket-style joint created by the humerus and scapula allows the arm to rotate circularly and to move up and out from the body. It is surrounded by soft tissue and strengthened by fibrous ligaments.
- Acromioclavicular (AC) joint: This joint forms the highest point of the shoulder and provides the ability to raise the arm above the head. The meeting of the scapula and clavicle forms it.
- Sternoclavicular joint: This joint is at the center of the chest where the clavicle meets the sternum. It allows the clavicles to move.
Surrounding each joint is cartilage to pad the meetings of the bones, ligaments to connect the bones, muscles, and tendons to attach the muscles to the bones.
