Axial x-ray photography of scaphoid

The specific operation steps of the detection method are as follows:

1. When the examinee stands facing the photographic table or sits down, his arms naturally droop and his palms face down.

2, elbow flexion 90, forearm neutral position.

3. The wrist is extended backward, so that the third metacarpal and the fourth metacarpal are parallel to the table top, and the midpoint of the connecting line between the second metacarpal and the third metacarpal is aligned with the center line of the table top.

4. The midline is aimed at the midpoint of the second metacarpal bone and vertically shoots into the detector.

5. After the frontal image is taken, rotate the hand forward 45 degrees, so that the center line is aligned with the third and fourth metacarpal spaces, and shoot at the detector vertically.

6. After the oblique image is taken, rotate the hand backward, so that the midpoint of the connecting line between the second metacarpal and the fourth metacarpal is aligned with the center line of the tabletop, and the center line is aligned with the midpoint of the second metacarpal and vertically shoots into the detector.
