The digits must be flexed excessively when positioning for a PA wrist radiograph in order to demonstrate the CMC joints open. True/False

False, If the digits are flexed too much when positioning for a PA wrist radiograph, the bases of the metacarpals obscure the CMC joints. The CMC joints must be demonstrated open on PA wrist radiographs, and this is accomplished by avoiding excessive flexion of the digits.
