What does it mean that the distance from A to H of the left supraspinatus muscle outlet is about 1mm?
The distance A-H from the outlet of the left supraspinatus muscle is about 1mm, which means that the distance between the acromion of the left scapula and the humeral head is 1mm, and the outlet of the supraspinatus muscle is a commonly used auxiliary examination method for shoulder X-ray examination, which makes up for the fact that only the coracoid process and acromion of the scapula are seen on the shoulder joint radiograph, and the humeral head overlaps with each other. The supraspinatus muscle outlet radiograph shows the lateral position of the scapula, which forms a Y-shaped projection with the coracoid process and acromion, and is completely separated from the rib margin, so that the distance between the acromion of the scapula and the humeral head can be clearly measured.
