A prospective evaluation combining the shoulder impingement view and arthrography was made in patients presenting with chronic shoulder pain. Five hundred and twenty-three patients with chronic shoulder pain were X-rayed using conventional views and impingement views. One hundred of these patients (mean age 62 years) had subacromial bony spurs on the impingement view; these underwent arthrography. They were divided into two groups according to the degree of spur formation--whether or not the size of the spur exceeded one half of the acromial width as measured from the outer margin to the acromioclavicular joint. Of the 100 subacromial spurs demonstrated on the impingement view, only 18 were visible on the conventional view as assessed by an independent radiologist. Arthrography showed 35 cases of rotator cuff tear. The size of the bony spur was strongly associated with the incidence of rotator cuff tear (P < 0.02).
对慢性肩部疼痛患者进行了一项结合肩部撞击视图和关节造影的前瞻性评估。523例慢性肩部疼痛患者接受了常规视图和撞击视图的X线检查。其中100例患者（平均年龄62岁）在撞击视图上有肩峰下骨赘；这些患者接受了关节造影。根据骨赘形成程度将他们分为两组——骨赘大小是否超过从外缘到肩锁关节测量的肩峰宽度的一半。在撞击视图上显示的100个肩峰下骨赘中，经独立放射科医生评估，只有18个在常规视图上可见。关节造影显示35例肩袖撕裂。骨赘大小与肩袖撕裂发生率密切相关（P < 0.02）。
