We report the clinical findings in the shoulders of fifty-two patients
who had ankylosing spondylitis. The three major patterns that were found
included limitation of scapulothoracic motion (forty-one patients), acute
inflammatory arthropathy of the sternoclavicular or acromioclavicular joint
(six patients), and severe restriction of glenohumeral motion (five
patients). Although radiographic abnormalities were common, they correlated
with the clinical findings in only minor respects.
