The Stecher method is used for the PA axial projection of the wrist. The patient's arm is extended, and the hand is placed palm down. The projection demonstrates the superficial anterior compartment of the forearm.
Step-by-step explanation:
The Stecher method is commonly used for the PA axial projection of the wrist. In this method, the patient's arm is extended and the hand is placed with the palm down on the image receptor. The central ray is directed horizontally and enters the wrist joint from the posterior side. This projection demonstrates the superficial anterior compartment of the forearm, which includes the flexor tendons and muscles that bend the wrist toward the body.
