Abstract

|
|
|
The shoulder links the upper extremity to the trunk and acts in conjunction with the elbow to position the hand in space for efficient function. It consists of the glenohumeral, acromioclavicular, sternoclavicular, and scapulothoracic articulations and the muscular structures that act on them to produce the most dynamic and mobile joint in the body. An absence of bony constraints allows a wide range of motion at the expense of stability, which is provided for instead by the various ligamentous and muscular structures. The biomechanics of the shoulder are complex, and a complete discussion necessitates analysis of articulations that make up the shoulder complex. This review describes the anatomy of the various aspects of the shoulder complex and shows how their structures allows for efficient biomechanical functions.
