The anteroposterior (AP) projection is particularly beneficial when imaging a patient's hand if the fingers cannot fully extend. This technique allows for a clear representation of the hand while accommodating for limited mobility in the fingers. By positioning the hand with the palm facing up and the fingers in a relaxed position, the AP projection can still provide useful anatomical information, notably the metacarpals and phalanges, even though the fingers are not fully extended.

In situations where strict adherence to standard projections may not be possible due to patient discomfort or inability to cooperate, using the AP approach can help ensure that the necessary diagnostic information is still obtained. This is especially crucial in scenarios where trauma or other conditions may limit the patient's ability to extend the fingers fully.
