WHAT’S BEHIND THAT SORE SHOULDER?

Your shoulder would win many design awards if we had made it in a lab rather than over ions of evolution. It’s an amazing bit of engineering that allows a wide degree of motion in your arm — everything from smashing a tennis ball to paddling out through the break at Trestles to throwing a curveball. The shoulder consists of several joints and an assortment of tendons and muscles.

But complexity has its shortcomings; the shoulder can be a source of pain and weakness, both from acute injury and also from the simple effects of wear and tear. From tearing the rotator cuff (Dodger pitcher Tommy John made that injury famous) to separating the shoulder to AC joint pain, myriad issues can develop with the shoulder

At Orthopaedic Surgery & Sports Medicine, Dr. Dini is all about diagnosing and treating your shoulder problems. Here are some of the most common factors causing your shoulder pain.

SHOULDER ANATOMY 101

Your shoulder consists of three bones: the upper arm bone (humerus), the shoulder blade (scapula), and the collarbone (clavicle). The head of the humerus fits into a socket in the shoulder blade. A combination of muscles and tendons, known as the rotator cuff, keeps the humerus centered in the socket. They attach the humerus to the shoulder blade.

CAUSES OF YOUR SHOULDER PAIN

Your shoulder pain usually comes from one of four areas: tendon issues, instability, fracture, or arthritis. Here’s a more detailed breakdown.
