Ancient physicians documented shoulder dislocations in wrestlers and soldiers, treating them with bandages and immobilization. Hippocrates himself described a technique for reducing a dislocated shoulder using traction and counter-pressure from the physician's own foot placed in the patient's armpit — a method still referenced in orthopedic teaching today, even if the tools have changed. For centuries afterward, treatment remained largely limited to splinting and rest, since the shoulder's complex web of muscles, tendons, and ligaments wasn't yet well understood.

With Renaissance anatomy, the shoulder's complexity became better understood. Detailed anatomical study during this period — most notably by Andreas Vesalius, whose dissections corrected centuries of inherited anatomical error — revealed the shoulder as a shallow ball-and-socket joint held together primarily by surrounding soft tissue rather than bone, explaining both its remarkable range of motion and its vulnerability to injury. This shift from guesswork to direct observation laid the groundwork for more precise diagnosis of shoulder conditions in the centuries that followed.

By the 20th century, sports medicine emphasized exercise and rehabilitation. As organized athletics grew and injuries like rotator cuff tears and impingement became better recognized, physicians and trainers began shifting away from prolonged immobilization toward early, guided movement — recognizing that a stiff, underused shoulder often healed worse than one kept appropriately mobile. This era also saw the rise of physical therapy as a distinct discipline, giving patients a structured path back to strength and function after injury.

Today, conservative care uses chiropractic, massage, and rehabilitation to restore function without invasive methods. Rather than treating the shoulder in isolation, modern approaches often consider the neck, upper back, and posture as a connected system, since dysfunction in any one area can shift stress onto the shoulder joint itself.
