The presence of an acromial spur implies a rotator cuff disorder due to impingement between the acromial spur and the rotator cuff. The purpose of the study was to observe acromial spurs using ultrasonography and to compare measurements between plain radiographs and sonograms.
We retrospectively enrolled 51 consecutive patients with acromial spurs, which were interpreted on preoperative plain radiographs (supraspinatus outlet view and 30° caudal tilt) and preoperative sonograms. The ultrasonography transducer was held vertically and continuously moved laterally, which corresponded to the long axis of the long head of the biceps. The distance from the most distal margin of the original acromion to the most projected point of the acromial spur was measured.
No significant difference was found between the plain radiograph and ultrasonography measurements (p=0.186). A moderate to strong correlation was detected between the ultrasonography and supraspinatus outlet-view measurements (r=0.776, p=0.000).
Anteriorly projected acromial spurs were well-visualized by ultrasonography. No discrepancy in acromial spur length was detected between the use of plain radiography (supraspinatus outlet view and 30° caudal-tilt view) and ultrasonography. The correlation coefficients between the plain radiography and ultrasonography measurements exceeded 0.7.
肩峰骨刺的存在意味着肩袖疾病是由肩峰骨刺与肩袖之间的撞击引起的。本研究的目的是使用超声观察肩峰骨刺，并比较X线平片和超声图像的测量结果。
我们回顾性纳入了51例连续的肩峰骨刺患者，这些患者在术前X线平片（冈上肌出口位和尾端倾斜30°位）和术前超声图像上均有诊断。超声探头垂直握持并沿外侧连续移动，该移动方向对应于肱二头肌长头的长轴。测量从原始肩峰最远端边缘到肩峰骨刺最突出点的距离。
X线平片和超声测量结果之间未发现显著差异（p = 0.186）。超声与冈上肌出口位测量结果之间检测到中度至强相关性（r = 0.776，p = 0.000）。
超声能很好地显示向前突出的肩峰骨刺。在使用X线平片（冈上肌出口位和尾端倾斜30°位）和超声测量肩峰骨刺长度时未发现差异。X线平片与超声测量结果之间的相关系数超过0.7。
