The shoulder is a ball-and-socket joint formed by the head of the humerus (the arm bone) and the glenoid labrum (the name for the socket of the shoulder joint in the scapula). The shoulder joint is very mobile – allowing great freedom of movement for the arm (much more than the equivalent joint in the hip). This greater mobility means that te shoulder joint is less stable. The stability of the shoulder joint also relies a lot on the ‘rotator cuff muscles’ – four muscles (supraspinatus, infraspinatus, subscapularis, teres minor) inserting around the shoulderjoint that help move it, as well as providing stability. These muscles are a common source of pain. Shoulder pain is common, and can result from a number of conditions. Importantly, pain felt in the shoulder region does not necessarily mean that the pain is coming from the shoulder. The pain could be caused by neck problems, or referred from internal structures.
You may not realize how important your hands, wrists and elbows are until you suffer an injury or condition that causes pain when doing simple tasks like picking up a fork, moving your wrist or straightening a finger. Hand, wrist and elbow issues can prevent you from going to work, participating in sports or taking care of your family. Fortunately, we can recommend several treatments to resolve pain and disability.
