Netter’s Musculoskeletal Flash Cards Jennifer Hart, PA-C, ATC Mark D. Miller, MD University of Virginia This page intentionally left blank Preface In a world dominated by electronics and gadgetry, learning from flash cards remains a reassuringly “tried and true” method of building knowledge. They taught us subtraction and multiplication tables when we were young, and here we use them to navigate the basics of musculoskeletal medicine. Netter illustrations are supplemented with clinical, radiographic, and arthroscopic images to review the most common musculoskeletal diseases. These cards provide the user with a steadfast tool for the very best kind of learning—that which is self directed. “Learning is not attained by chance, it must be sought for with ardor and attended to with diligence.” —Abigail Adams (1744–1818) “It’s that moment of dawning comprehension I live for!” —Calvin (Calvin and Hobbes) Jennifer Hart, PA-C, ATC Mark D.

Other articulations here include the acromioclavicular and the sternoclavicular joints. The bony anatomy does not provide much stability to the shoulder joint.

The glenohumeral ligaments are really just thickenings of the glenohumeral joint capsule.
