What is the anatomy of the shoulder?
The shoulder is a ball and socket joint which connects the humerus (upper arm), scapula (shoulder blade), and clavicle (collarbone). It is one of the largest joints in the body and is also one of the most complex. The shoulder consists of two main joints, the acromioclavicular joint, and the glenohumeral joint. These two joints work together, allowing for movements such as rotation, extension, flexion, and lifting. Dr. Riley J. Williams, orthopedic shoulder specialist, has years of experience diagnosing and treating patients in Manhattan, Brooklyn, New York City, NY and surrounding areas who have experienced an injury or an unusual condition of the shoulder.
