The shoulder is the joint with the widest range of motion in the body. It is made up of three bones known as the clavicle (collarbone), the scapula (shoulder blade), and the humerus (upper arm bone) as well as muscles, ligaments and tendons. The shoulder joint consists of the humerus which attaches to the scapula and the head that rests against the glenoid.
Joints are the locations in your body where two bones meet. Movement of these bones against each other is what permits our bodies to move. Cartilage is located at the end of our bones and is a smooth, slippery tissue that allows the bones to slide against one another with minimal friction. Once cartilage is damaged, it cannot heal itself and the progressive deterioration leads to a loss of cartilage and exposed bone. Because pain sensors are located in bone and not in cartilage, it is the exposed bone that results in a painful joint.
As you might expect, there are many different reasons why you could be feeling shoulder pain, including injury, infection, dislocation and arthritis. Fortunately with the HemiCAP technology you can restore your joint instead of undergoing a total joint replacement.
