The human form has four appendages, both arms and two legs, that allow us to walk, crawl, reach, push, and pull. Our legs and arms are critical to our survival as a species. Your shoulders connect your neck to your upper arms.
Your shoulder has three parts; the humerus (long arm bone), the clavicle (collarbone), and the scapula (shoulder blade). Their successful partnership depends on a layer of cartilage, which keeps the joints working smoothly.
There are two joints in the shoulder. One is the glenohumeral joint. The top of the humerus bone, the ball-shaped part, and the scapula’s outer edge make up the shoulder joint. The shoulders have more ability to move than any other in the body. The shoulder joint can move your arm forward and backward, move your arm in circles, and move your arm up and away from your body.
Several common conditions can affect the shoulder, including rotator cuff injuries, and what is called a frozen shoulder syndrome. There are exercises that can help protect your shoulder from these injuries and prevent shoulder pain. When should you see your doctor about shoulder problems? We’ve got a handy guide to treating your shoulder pain at home and when to call for an appointment at your physician’s office. There are quite a few treatments to try before replacement surgery.
Rotator Cuff Injuries
That impressive range of motion of the glenohumeral joint is due to the rotator cuff, a commonly injured group of four tendons. The purpose of ligaments is to connect your muscles to bones. When the rotator cuff tendons become inflamed, damaged, or swollen, then lifting your arm over your head may be nearly impossible.
