Question

What is the method used for PA axial projection wrist in stecher method?

1) Anterior oblique
2) Posterior oblique
3) Lateral
4) None of the above

Answer 1

The method used for PA axial projection of the wrist in the Stecher method is Posterior Oblique. This technique utilizes a PA position with ulnar deviation and a 20-degree angled sponge to visualize the carpal bones, especially the scaphoid.

Step-by-step explanation:

The method used for PA axial projection wrist in Stecher method is Posterior Oblique. This radiographic positioning technique is used to visualize the carpal bones, particularly the scaphoid bone, without superimposition. In the Stecher method, the patient's hand is placed in a PA (posteroanterior) position with a slight ulnar deviation. To achieve the necessary angle, the wrist is typically elevated on a 20-degree angle sponge or foam pad, causing the central ray to project in a 20-degree angle towards the elbow. This positioning effectively gives a detailed view of the scaphoid without the interference of the radius and ulna which is common in a straight PA projection method.
