The profile view of the acromion

A previously undescribed roentgenographic view shows the acromion in "profile." A sagittal view of the acromion outlines its bony architecture, specifically, the subacromial portion. This view is clinically useful in the perioperative evaluation of patients with impingement syndrome and can be especially revealing in some cases of persistent symptomatic impingement following previous acromioplasty. The view also provides an excellent perspective for roentgenographic examination of os acromiale. It is reproducible and relatively easy to obtain. The acromion is but one component of the subacromial arch, but this view is a valuable additional diagnostic tool to be used in evaluating the sometimes perplexing problem of impingement syndrome.
